We’ve been taught that Apple devices are a standard of reliability. If you want a stable computer, you get a Mac. If you want a phone that can handle hours of unbreakable connection, you get an iPhone. There’s some truth to it, but it would be wrong to think Apple devices are invincible. If you’ve ever experienced random Mac shutdowns, you know for sure Apple experience is not always flawless.
Worst of all, shutdowns might happen while you’re working on something important. This results in unsaved documents and your work being seriously delayed. In this article, we’ve collected all fixes you’ll ever need if your Mac starts shutting down. It also includes the guide to fixing a 13-inch MacBook Pro misbehavior.
One savior for all Mac issues
Save hours of your time, treating Mac shutdowns, app misbehavior, and other problems with Setapp — 180+ best apps for Mac.
Troubleshooting random Mac shutdowns
Restarting your Mac is always the first idea that should come to mind. And sometimes, it really helps. Even though your Mac is technically shut down, restart Mac once again — the proper way. This will kill the background processes, ensuring your Mac has a healthy startup.
Once you power up your Mac after a shutdown, press Command + Alt + Esc to force quit background apps and then put your Mac to sleep, restart, or shut down from the Apple menu.
Unfortunately, this will hardly prevent your computer from shutting down again. If your computer keeps shutting down, consider SMC and PRAM resetting.
Reset the SMC
The SMC (System Management Controller) is responsible for battery and thermal management as well as any processes related to closing and opening your MacBook lid and pressing the power button. Clearly, it might be a part of the shutdown problem.
There are some differences on how to reset the SMC, depending on the type of computer you own. Pick your device from the list below and try it out.
MacBooks with removable or nonremovable battery
Reset the SMC on Mac laptops with removable battery:
- Shut down your Mac.
- Remove the battery (if you don’t want to do it yourself, go to the nearest Apple Service Center or Apple Retail Store).
- Press and hold the power button for a few seconds.
- Reinstall the battery and turn on your computer.
Reset the SMC on Mac laptops with nonremovable battery:
- Shut down your Mac from the Apple menu.
- Hold Shift + Control + Option + the Power button (or Touch ID button) for about 10 seconds.
- Release the keys and turn on your computer.
Mac desktop computers
Here’s how to reset the SMC if you’re an owner of iMac, Mac Mini, Mac Pro, or Xserve. Note that this method works only for desktop computers without the Apple T2 Security Chip.
- Shut down your Mac from the Apple menu.
- Unplug the power cord and wait for about 15 seconds.
- Plug the power cord back in and wait for about another 5 seconds.
- Turn on your computer.
Computers that have the Apple T2 Security Chip
Here’s the complete list of Macs with the Apple T2 Security Chip:
- iMac Pro
- Mac Pro (2019)
- Mac mini (2018)
- MacBook Air (2018 or later)
- MacBook Pro (2018 or later).
You can also find out whether your computer has the T2 Security Chip by holding Option > Apple Menu > System Information. From there, navigate to Controller or iBridge in the sidebar. You’ll find the answer under “Model Name.”
Here’s how to reset SMC if your computer has the T2 Chip:
- Shut down your Mac from the Apple menu.
- Hold the power button for about 10 seconds.
- Release the power button and wait for a few seconds before turning on your Mac.
If it didn’t work, try shutting down your Mac and then unplug the power cord. Wait for about 15 seconds, plug the power cord back in, and turn on your computer.
Here’s how to reset SMC if your computer doesn’t have the T2 Chip:
The traditional reset method for Macs without the T2 Chip is identical to the one described above. However, if it doesn’t eliminate the problem, you might need to try this one:
- Shut down your Mac from the Apple menu.
- Press and hold the right Shift key + the left Option key + the left Control key for about 7 seconds.
- Once the Apple logo appears on your screen, continue holding Shift, Option, and Control + the Power button for another 7 seconds.
- Wait for your Mac to turn off and release the buttons.
- Turn on the computer again.
Reset the PRAM
PRAM, or Parameter RAM, is another part of your computer that might be responsible for misbehavior. It stores lots of minor preferences — including those related to the startup disk. Resetting PRAM might be a good way to prevent shutdowns:
- Shut down your Mac from the Apple Menu.
- Press the Power button and hold Command + Shift + P + R.
- Release the keys once you see the Apple logo for the second time, hear the second startup time, or after 20 seconds.
App Is Not Shutting Down On Mac Iphone
After resetting PRAM, you might need to go to the System Preferences and adjust some of your settings — including volume and display resolution.
Update your macOS
There’s always less likelihood your Mac will be shutting down if you keep the macOS up-to-date. Unless you use 32-bit apps that are unsupported on macOS Catalina, we recommend to upgrade your Mac. You can check for any pending updates in Apple Menu > About This Mac > Software Update.
How to fix 13-inch MacBook Pro shutting down
If you have a Mac Pro with a Touch Bar instead of function keys, there’s a dedicated troubleshooting method for your device. While Apple hasn’t launched the hardware replacement program for this device yet, it’s important you make note of the following:
- Discharge your MacBook Pro battery to 90% and below.
- Close all open applications.
- Connect the charger and switch to the Sleep Mode.
- Close the lid and let your Mac Pro charge for about 8 hours.
- Turn on your computer and update it to the latest macOS version.
If MacBook keeps restarting
Another issue is your Mac getting into the loop of constant restarting. It might be impossible to trace the reason for such restarts, so make sure you know all the fixes. But before taking any further steps, create a bootable back up of your disk with Get Backup Pro to keep everything you store on your Mac protected.
Disconnect peripheral devices
Make sure no external devices such as hard drives or printers are connected to your Mac. If it’s a desktop computer, you might leave a keyboard, mouse, and a display connected — but nothing beyond that. Turn on your Mac and continue working as usual.
Update software
Quite often, outdated software might cause restarting. Here are a few tips on how to deal with it:
- Update apps if you have any software updates pending.
- If there’s a particular app causing the problem, contact the developers to help you solve it, or remove the app from Mac.
- Reinstall third-party apps.
Reinstall macOS
If you’ve exhausted all the update attempts, your next step would be to reinstall macOS from Recovery. You’ll need to erase your startup disk first, but with the data backed up, there’s no need to worry. You can check the instructions on how to reinstall macOS on the Apple Support page.
Keep your Mac healthy and avoid the trouble
App Is Not Shutting Down On Mac Windows 10
In many cases, random shutdowns have their symptoms: Your computer starts slowing down, the fans run at full speed and make loud noise, the apps go unresponsive. The other times, there’s no sign. Nothing. So it’s better to keep your Mac performance controlled so that you be warned whenever something goes wrong.
Tidy up your Mac with CleanMyMac X
CleanMyMac X is a cleaning utility for Mac that makes your machine tidier and therefore faster and stronger. It eliminates all the clutter from your hard drive and operating system in one scan.
Cluttered Mac is generally slower. If there are heaps of apps that haven’t been updated on your Mac, it can also shut down unexpectedly. This is where CMMX comes to help. From old caches to duplicates, CleanMyMac X wipes away everything that might be hampering your progress. The app will tell you about malware threats and let you know if there are any particularly large files you haven’t attended to.
Prevent future Mac shutdowns
Get iStat Menus to stay in the know about your Mac’s health. So that you never even get close to fixing a shutdown.
Monitor Mac’s health with iStat Menus
Your Mac will give you a hint when it’s not doing well if you have iStat Menus. The app adds tons of Mac health indicators to your menu bar. You’ll be able to control free disk space, instantly see what apps are draining your Mac’s battery, and view active processes. It’s the best way to ensure your computer never even starts misbehaving.
Create bootable backups with Get Backup Pro
We couldn’t emphasize this more: Before running any diagnostics or reset on your Mac, create a bootable backup of your disk. If you accidentally or purposefully delete anything, you’ll be able to get it all back with Get Backup Pro.
While all three utilities mentioned above are pretty pricey if you buy them separately, we recommend to use them via Setapp. It has all of these, plus around 160 other useful Mac utilities for a monthly subscription price starting at $9.99.

If your computer keeps shutting down
Take it to the nearest Apple Service Center. If you’ve tried to force shutdown Mac, reset SMC/PRAM, and update your macOS, but your Mac continues acting naughty, you’ll need to get service for your Mac. Most likely, it will be wiped — so prepare a backup in advance. Anyway, we wish you a long-living Mac and a productive work routine!
Make your Mac invincible
Get Setapp, a toolkit with fixes for all Mac problems
After summer comes macOS. This long-standing tradition started by Apple is the most exciting moment of the year — seeing your Macs improve and gain new bells and whistles. In 2019, we’re welcoming Catalina, the 10.15 version of macOS named after Catalina island in California. Apparently, it’s hot.
The operating system boasts a whole lot of new macOS features like Sidecar, iOS apps porting, and major Photos update. To try the features right away, you can install Catalina from the Software Update tab.
However, be prepared for some troubleshooting. The acquaintance with the new macOS doesn’t always go smooth — and with macOS 10.15 deeming support for lots of software, many things will not go smooth. We’ve collected the key macOS Catalina issues you may encounter, along with the ways to fix them.
macOS 10.15 Catalina problems and their fixes
Giving up Catalina is a decision you can choose to make. But before rolling back, ensure you use every bit of advice as to how you can fix the common problems. Sometimes, a quick fix can solve your concerns.
Get macOS problem fixes on Setapp
Beta or not, you can safely install any version of the new macOS. Setapp and its 150+ apps will solve every Mac concern you have.
Problems with macOS Catalina you can solve:
macOS 10.15 Catalina won’t install
This is the classic problem that arises with every macOS release: The installation won’t start or you face the “Catalina installation stuck” problem — when it freezes and you see no progress on the install. No matter how many times you start over, you keep getting an error trying to install Catalina.”
How to fix:
- Apple recommends to reset SMC. Shut down your Mac, and hold Shift + Ctrl + Option + Power button for about 10 seconds, with your cable plugged in. Click on the power button and wait for your Mac to start up.
- Try resetting NVRAM or PRAM. Shut down your Mac, and hold Option + Command + P + R for about 20 seconds. Wait for your computer to restart.
- Reinstall from macOS recovery. Hold Option + Command + R to reinstall. Once you see the startup screen, start the installation again.
- Some users reported they were prompted to enter administrator password several times to complete the installation. So it might be something for you to try as well.
- In most cases, macOS Catalina cannot be installed on Macintosh HD, because it doesn’t have enough disk space. If you install Catalina on top of your current operating system, the computer will keep all the files and still need free space for Catalina. So the easiest fix would be to clean up your system with CleanMyMac X before upgrading. All the system junk, app leftovers, and unneeded files will go away in a minute.
- Backup your disk and run a clean install. This will wipe away your current system files, leaving space for macOS Catalina — so yes, this option is for the brave. If you use a solid backup solution, you’ll keep your data safe, though. Get Backup Pro is a nice way to do it — unlike Apple’s Time Machine, the app allows running bootable backups.
Say you’ve cleared up and backed up your disk. But your Mac still gets stuck at the installation and shows “not enough space” error, so you can’t get out of the cycle. In this case, there’s another fix you can try:
- Reinstall Mojave. No worries, this won’t delete your disk. Reboot your Mac and hold Command + R to enter the Recovery Mode. Click Reinstall macOS.
- Restore from your backup. If you have a Time Machine backup, enter the Recovery Mode again and select “Restore from Time Machine Backup.” Select the backup from the list and restore your files.
Some users also report they tried to reboot into Safe Mode and take the installation from there; the others used a newly created admin user — but most attempts have been unsuccessful.
We must agree that macOS 10.15 is one of the slowest systems in terms of installation. But if you use the hacks described above and have a little patience, you’ll be able to get to the “Catalina installed” point.
If you can’t login after upgrading to Catalina
There’s a known problem of failing to login after the installation. Unfortunately, the only way to fix it — at least for now — would be to roll back to Mojave:
- Clean up your Mac with CleanMyMac X and backup your data.
- Save passwords to ensure you don’t lose license keys and settings.
- Create a bootable installer of Mojave (after Catalina goes public, you can download Mojave here).
- Delete macOS Catalina: Apple menu > Restart > Command + R > Disk Utility > your startup disk > Erase.
One of the things Mac users are particularly excited about is the new Sidecar feature. It comes as a handy solution for those wanting to expand their workspaces. You can either mirror your Mac’s screen to iPad or use your iPad’s screen as an extension of a Mac.
If the only reason you’re here is because you want Sidecar, we have to warn you it might not work with your new macOS. Reddit is full of user reports about the feature unavailable on macOS Catalina. Most likely, this is the issue of compatibility.
How to fix:
Here are the ways to fix Sidecar problems:
- Get the new iPadOS 13. Unfortunately, macOS Catalina doesn’t work with iPadOS 12. So basically, you have to use the recent operating systems if you want to try Sidecar.
- Make sure your Mac is one of the compatible devices. Sidecar works on:
- 2019 Mac Pro
- Late 2018 Mac mini +
- Late 2018 MacBook Air +
- 2017 iMac Pro
- Mid 2016 MacBook Pro +
- Early 2016 MacBook +
- Late 2015 iMac +
- Try connecting your iPad with a cable. With Sidecar, you should be able to connect your iPad wirelessly. If this doesn’t work, the cable might solve the issue.
Battery drain on macOS Catalina
Many of the previous macOS releases were known for battery life concerns — greedy apps, Safari and Chrome draining battery, or power-saving not working. There has been no major battery drain issues reported by the Catalina users so far.
How to fix:
Just to make sure you don’t encounter the problem as well, here are a few precautions:
- Check for apps that use significant energy. For a quick insight, check Apple’s in-built Activity Monitor. It shows the “Energy impact” for every application — calculated based on CPU, network usage, and other factors.
- Have a solution for battery health monitoring. iStat Menus is a perfect fit if you need detailed analytics on disk activity, CPU usage, battery life, memory load, and much more. The app shows all the data right in your menu bar. Plus, you can customize what’s being monitored flexibly.
- Use Screen Time to limit the use of apps. This is the brand-new app on macOS Catalina, which helps you live a healthier Mac user life. Set time limits for the use of specific apps or app categories and schedule downtime. The main goal is to track how much time you spend on the computer, but you can also use it to optimize battery life on Mac.
Apps not working on macOS Catalina
In the attempt to speed up your Mac’s performance, Apple is killing 32-bit app architecture with the release of Catalina. This means you have to switch to 64-bit, for good. You might see the messages like this when trying to launch an app:
The chances are it’s one of the oldies.
How to fix:
CleanMyMac X can pretty much solve every app problem on macOS Catalina.
Uninstall all 32-bit apps in a click
No more digging through the settings. Download CleanMyMac X and batch uninstall every outdated app on Mac.
- Use Updater to search available app updates. Maybe the app is not working, because it needs upgrading. If you’ve missed the update notification, you won’t know about this. To solve the issue, CleanMyMac X will show you the full list of apps with available updates from developers. The best thing is you can run a batch update right in the app.

Mac Not Shutting Down Properly
- Uninstaller gives you an easy way to reset or get rid of 32-bit apps. The Apple way of checking for 32-bit applications is quite easy: access About This Mac > System report > Applications. However, once you find apps with the outdated architecture, you’ll have to go and uninstall each of them separately. The Uninstaller feature in CleanMyMac X simplifies things for you — filter by 32-bit and get rid of each of them.
- If there’s no particular reason an app misbehaves, try resetting it. Guess what, CleanMyMac X has it covered too. In Uninstaller, click on the arrow button next to the app and choose Reset. As easy as that.
While app notarization takes time, you can expect many apps being unavailable after the release of Catalina. This doesn’t mean they are gone for good, though. Contact developers or follow official developer announcements to find out about compatibility plans.
OneDrive client problems on Catalina
Due to Catalina’s new security settings, Microsoft’s OneDrive may have a problem accessing your drive — even if you allow a full access. This is because macOS 10.15 comes with two disk volumes by default.
How to fix:
There are no surefire fixes just yet, but you can try to troubleshoot OneDrive by setting it up from the very beginning. This worked for some users, according to the Reddit discussion:
- Unlink your account and quit OneDrive.
- Remove OneDrive client from your Mac and delete the folder.
- Set up OneDrive again and make sure you allow full disk access in Security & Privacy.
iCloud problems on macOS Catalina
The most common issue with iCloud is that users are unable to download their folders. You can try downloading iCloud files separately — but that’s going to be a pain if you have an extensive library.
How to fix:
The best fix would be using Forklift app for your file management. The app is Catalina-ready and allows connecting local drives, Dropbox, iCloud, and tons of other storage sites.
If you’re setting up iCloud, there might be another issue standing in your way: Not being able to agree to the Terms and Conditions. The window will just keep popping up on your screen. An easy way to fix this would be to access System Preferences > Internet Accounts and then click on the iCloud icon. You’ll see a static Terms and Conditions window — click Accept and you’re good to go.
Replacing iTunes on Catalina
The new macOS 10.15 brought along the end of iTunes and the birth of the new Music app. Basically, it looks the same — but with music-only content. There’s a huge difference for people who rely on syncing Apple Music with third-party apps. The new app doesn’t support XML file support, which makes playlist syncing impossible across many apps. So if you use Apple Music for DJing, you’ll definitely have a problem.
How to fix:
The only fix to suggest here would be to stay away from Catalina if you need your XML apps to work with iTunes.
Music library issues
New Music app keeps freezing
There have been reports about the new music app freezing on Mac. Well, it’s the first splitting of iTunes, so it’s no wonder it doesn’t go smooth. In most cases, your Mac will keep showing the “library updating” status.
How to fix:
- Create a backup of your entire music library.
- Move your music out of the music folder.
- Go to ~/Library and remove every file related to “Music” and “iTunes.”
- Delete music caches in ~/Library/Caches.
- Restart your Mac and try to access the library again. It should be working now.
Memory usage problems with Apple Music app
Another problem you may come across is the Music app eating too much of your space. Pop up blocker for chrome mac. One user wrote the app used over 30GB of memory on his Mac.
How to fix:
Apparently, the problem is related to the memory management of Album Art. It is getting better, though. According to user reports, memory usage goes back to normal after restarting the app.
Mail search is broken
According to forum posts, your mailbox might get pretty messy after the upgrade — with no search functionality whatsoever. So if you try searching by keywords or recipient/sender name, the app will keep showing the numerical number of results. The reason could be the new Spotlight integration.
App Is Not Shutting Down On Mac And Cheese
How to fix:
- Open System Preferences > Internet accounts and remove your mail account.
- Restart your computer and once again add your mail account to the app.
- Try searching through your emails — it should be working now.
There have also been some early reports about emails missing from the Mail app — so you might want to wait for it to get fixed before upgrading, especially if you rely on Apple Mail.
App Store On Mac Not Working
Slowing down and overheating macOS Catalina problems
So here’s the thing: macOS Catalina should be faster than Mojave. 32-bit architecture was one of the things slowing an operating system down. It’s gone, and so are the issues with slow apps. Unfortunately, you can expect your Mac go slow and overheat anyway.
How to fix:
- Too many login items often cause your Mac to go slow. To eliminate the problem, disable apps from launching at startup. Go to System Preferences > Users & Groups > Login Items. Check the apps you don’t want to run at startup and click on the minus button.
- Reset SMC. This is a universal fix that helps solve the issues with overheating, battery life, slow Mac, and more. The process is pretty simple and doesn’t impose any risks of losing your data. To reset, shut down your Mac, but leave a charger plugged in. Hold Shift + Ctrl + Option + Power button for about 10 seconds. Click on the power button and wait for your Mac to start up.
Dock disappearing on macOS Catalina
On the Apple forum, people mentioned Dock disappearing from their screen after upgrading to Catalina. The nature of this mistake is unknown — some users connect it to PRAM resetting, the others say they had the issue when trying to work across two screens.
How to fix:
Try Option + Command + D. If it doesn’t work for you, do the following:
App Is Not Shutting Down On Mac Computer
- Go to Settings > Dock
- Change the Dock’s size so that it starts flickering
- Change the hide/show settings
- Customize the Dock’s position on screen (you can do it randomly).
Close the window and check whether it’s working now.
Internet not working after upgrading to Catalina
If you’re putting macOS 10.15 over your current system, you’re likely to encounter Internet connection problems.
How to fix:
The radical way would be to clean install macOS Catalina — it’s healthier for your Mac and will probably fix the issue. If you’re not ready to take a risk, try rebooting your Mac.
There has been a user report saying that Sophos caused the problem of network connection. So uninstalling it may be a fix as well.
Bluetooth not available on macOS Catalina
Well, that’s a problem. Definitely a huge one if you use AirPods. Deleting your Bluetooth.plist files might be the way to solve this.
How to fix:
- Open Finder > Go > Go to Folder
- Type Library/Preferences
- Find a file with the name “com.Apple.Bluetooth.plist” and delete it.
Safari extensions not working
While Apple is trying to transition to iOS-compatible extensions, it gradually deems support for many web extensions formats. On Catalina, you’ll face the problem with .safariextz files not working.
How to fix:
Just like with 32-bit apps, there’s no way to fix the missing extensions. If you can’t find a good alternative, you can switch to Chrome or another browser.
Storage filling up too fast
If you notice unusual storage filling up progress, this might mean your Mac captured too many redundant files during the Catalina installation. In most cases, these are APFS files and Time Machine backups.
How to fix:
If you can use a good Time Machine alternative like Get Backup Pro throughout the upgrade, do it. Otherwise, you can remove Time Machine leftovers after installing Catalina with CleanMyMac X. In the Maintenance tab, select “Time Machine snapshots thinning,” and run a cleanup.
To remove snapshots manually, use the following Terminal commands:
1. To view the list of snapshots:
tmutil listlocalsnapshots / tmutil listlocalsnapshots /System/Volumes/Data
2. To delete snapshots:
deletelocalsnapshots
Here’s a quick review of all mentioned fixes, which you can take with you:
Is macOS Catalina stable?
The short answer is yes — if you use it right. So before you decide to downgrade back to Mojave, make sure you’ve done the following things right:
- Backup your Mac with Get Backup Pro or any other reliable tool before running an installation.
- If you still need some of the Mojave functionality that won’t be available in Catalina, install the new macOS on partition.
- Make your Mac as clean as possible before upgrading.
- Get iPadOS 13 if you want to use the Sidecar feature.
- Get rid of 32-bit applications, even if this means killing your darlings.
- Backup your Music and then empty the folder along with music-related Library caches. The new Apple Music app is still pretty much unpredictable, so you need to ensure you don’t lose your playlist.
- CleanMyMac X is a solution for many Catalina issues, so you need it — badly. To cut the cost, you can get it through Setapp and receive extra tools like Get Backup Pro and Endurance.
