Have you ever found yourself staring at a computer screen, clutching your head in your hands, and asking the question, “Why won’t my Mac update?”
Computer trouble is always frustrating, and even more so with Macs because, to be frank, things don’t go wrong very often on a Mac. It gets easy to expect that nothing ever will.
But if you find yourself staring down a computer that just will not work right, don’t worry. There are ways to fix a corrupted Mac OS update. Read on to learn the symptoms of a corrupted update and what you can do about it.
Why Won’t My Mac Update?
You might see these problems or errors when you're trying to update your Mac. Here's what's causing them.
Symptoms and Error Messages
If you have a problem with your Mac’s latest update, chances are the problems are going to show up when you try to boot up the computer. You may get a message that reads “A critical software update is required for your Mac, but an error was encountered while installing this update. Your Mac can’t be used until this update is installed.”
You could also start getting a screen with a black background and white text in four languages. The text will read, “You need to restart your computer. Hold down the Power button for several seconds, or press the Restart button.”
In some cases, your Mac won’t even get as far as booting up long enough to get you an error message. Some update problems can be so severe that your system won’t boot up at all, even if you know the computer is plugged in and working fine.
More commonly, you may see a system that begins to boot and then crashes. Your Mac may get stuck on a blue or gray screen and refuse to move from there. Or you may get a flashing question mark on your screen.
Causes of the Problem
Oftentimes if your Mac runs into an issue with an update, it’s because the update process was interrupted somehow. Maybe you lost power or lost patience and unplugged the computer partway through the process. If a laptop battery died or you tried to turn a system off before it finished updating, it can land the computer in a sort of limbo between updated and running an update.
Imagine if you and a friend were driving down a highway you know when you fell asleep. Once you woke up, you were on a stretch of road you didn’t recognize, and you didn’t know how to get back home or to your destination.
That’s the state your computer finds itself in when an update is interrupted – as long as it’s got power during the update, it knows where it is on the road, but as soon as it goes to sleep, it’s lost the way.
If your computer won’t boot up or boots and then crashes, you may be dealing with a problem called a kernel panic. This is where your computer runs into a critical problem when it tries to turn on. Its response to hitting critical problems is to try to start fresh, so it reboots, but if the problem is with the system, it can get stuck in an endless loop of reboots and crashes.
There are a ton of things that can cause a kernel panic, including installing new apps or not getting them installed in the right folder. You may have outdated drivers or plugins or apps that conflict with each other. There may also be some hardware issues or broken disk permissions.
How Do I Update My Operating System on My Mac?
We'll guide you through running updates on your Mac, whether it's old or new.
Normal Updates
So before we dive into troubleshooting, let’s talk about how you update a Mac under normal circumstances. First open the System Preferences app, which should be under an icon in your dock that looks like a gear inside a silver box. You can also click the apple symbol at the top left of your screen and choose “System Preferences.”
If you’re up to date on your software, you should have a “Software Update” option under System Preferences. When you click this, it will check for updates to your operating system. If it finds any updates, it will give you information about what they are and give you the option to “Update Now.”
You can also choose to have your Mac automatically run any updates that come through. This will save you having to check every so often on whether your system has any updates waiting. It can also help fend off problems before they start since it will prevent kernel panics over outdated drivers and the like.
Earlier OS Versions
If you aren’t up to date on your operating system, you’ll have to go through a couple of extra steps to update your computer. You’ll still start in System Preferences, but this time you’ll go to the App Store icon. You can also open the App Store app from your launchpad; the Icon looks like a white A made of a pencil and a paintbrush on a blue background.
In the App Store, navigate to the “Updates” section of the top menu bar. This will be on the right side of the menu bar next to “Categories” and “Purchased.” You’ll be able to check here for new updates both to apps and to your operating system and run them if they come up.
You may notice that you have a few incompatible app updates listed. More than likely this is because you haven’t updated your operating system software in a long time. There may be some apps that have new updates that are not compatible with your current operating system.
The Latest Version
The latest version of the Mac OS is version 10.15, or Catalina. This version is set to release on October 4, 2019, though it has been out on a beta testing basis for a while now. You can check if your computer is running this version yet by clicking the apple icon at the top left of your screen and selecting “About This Mac.”
There are two sides to the question of whether to update your Mac; will you get all the cool new features, or will you just wind up with a computer that no longer works the way you need it to?
In general, if your computer was made in the last five years, it’s a good idea to run the update. But if your computer is more than five years old, it’s best to stick with what works for you.
Updating Old Systems
So what if you do still have some of those older operating systems running on your computer? It depends a lot on which computer you’re running, but almost all of them will still support Sierra. Only newer machines will support Mojave and Catalina, and nothing above a 2015 Retina will still run El Capitan or the older operating systems.
You may be wondering what to do with the “Install Mac OS Mojave” app you have leftover after your 10.14 update. You can delete this app with no problem; that’s the installer, and it doesn’t serve any purpose once the OS is installed. You can go to “Applications” in Finder, drag the app to the trash can, and clear the trash can to get rid of it.
What Do I Do If My Mac Won’t Update?
There are some steps you can take to get your Mac updated even if it seems stuck.
Install in Safe Mode
If you can’t get your Mac to update properly, the first thing to do is try to run the update in Safe Mode. Safe Mode is a diagnostic mode that you find in both Windows and Mac operating systems. It prevents some of the usual background processes from running, which can make it easier to sniff out bugs on a PC and can keep your computer from loading some of the programs that may be causing it problems during booting on a Mac.
The easiest way to boot into Safe Mode on a Mac is to hold down the shift key while it restarts. So if your computer is off, press the Start button, and if it’s on, start the reboot sequence. As soon as the apple appears on the screen, press down either of the Shift keys and hold it down while the computer boots up.
You can let the shift key go as soon as the login screen appears on your computer. If you’re not sure if you’re in Safe Mode, hold down the option key, click on the apple icon at the top left corner of your screen, and click “System Information.” This should pull up a window with a menu on the left that reads “Hardware,” “Network,” “Software,” and so on.
If you click on the Software menu, you should get a screen to the right that shows your system software overview. Under the Boot Volume, you should see Boot Mode, and it should be in “Safe.” If it isn’t, try an alternate method of booting into Safe Mode.
Once your Mac is in Safe Mode, run through the same update process we discussed before. With other programs out of the way, it may be able to make it through the update and then boot up normally.
Wait It Out
It may sound strange, but one of the best things you can do when your computer won’t update properly is to just wait it out. Yes, computers can indeed execute about two billion operations a second. But what you’re asking it to do is the virtual equivalent of building a fully furnished mansion out of Lego bricks; even at two billion blocks a second, that’s going to take some time.
Your computer is good at figuring things out, so try giving it the time to do so. It’s not a bad idea to boot into Safe Mode first, as we discussed but set the update running and do not touch it until you are certain the problem isn’t going to solve itself.
This can mean letting the computer sit and work things out for eight to twenty-four hours; after that, you can be confident this isn’t a self-fixing problem.
When you’re doing regular updates, it’s a good idea to set them to run when you go to bed. Make sure your computer is plugged in and set so that it won’t go to sleep after a certain amount of inactivity. Then let it run all night, and in the morning, it should have had plenty of time to work out all the update issues it needed to; your mansion will be ready to move into.
Use a Recovery
If you absolutely cannot get your computer to install the update on its own, it may be time to bring in a recovery backup. This will do a few things; for one, it will make sure none of your files get lost in the update shuffle. But for another, it will act as a sort of air rescue for your lost computer operating system.
So let’s go back to our road trip metaphor from earlier. Running a backup would be like going back in time and making sure you had a road map and plenty of coffee on hand during your trip. This time, you don’t fall asleep, you catch every turn you take, and you get where you’re going just fine.
You can boot your computer into recovery mode by starting it back up or restarting it. When the apple logo appears on the screen, press Command+R. This will allow you to connect to the internet to get a new operating system download to start the process over.
Recover Your Data
Trying to answer the question “Why won’t my Mac update?” is frustrating, but you don’t have to resort to pitching a thousand-dollar machine. There are ways to manage a corrupted update, and as long as your files are safe, you can get things back up and go again. But you want to make sure none of your files are unprotected.

One of the best things about a Mac is the range of free apps that come pre-installed. However, that doesn’t mean you won’t download and install other applications from time to time. It should be easy — like most Apple tasks — but that isn’t always the case. This post explains what you can do if your Mac won’t install apps.

Common error messages when installing Mac apps
When trying to download or update apps, you might get one of the following messages:
- “App can’t be opened because it is not from the App Store.”
- “App failed to download. Use the Purchases page to try again.”
- “The application could not be downloaded. The installation could not be started.”
If this, or something similar, has happened to you, we have the solution below. But first, let’s make sure you’ve got the basic requirements to install an app.
What do you need to install apps on a Mac?
In order to download, install, or update an app on your Mac you will need the following three things:
- a good Internet connection
- ample free storage
- an administrator password.
Check your Internet connection by streaming a video online. If the video is slow to load, contact your Internet service provider for assistance.
Check your storage by clicking the button in the menu bar and selecting About This Mac > Storage. Ensure you have at least as much space as recommended by the app developer. Preferably a bit more.
You’ll often need an administrator password to complete the installation of an app. If need be, ask the administrator to log on and install the app themselves. Otherwise, they may need to enter their password when prompted from your account.
How do I open apps that aren’t from the App Store?
Macs benefit from a lot of in-built safety precautions, but when downloading third-party apps they can sometimes appear overzealous. By default, your Mac won’t install apps from anywhere other than the App Store, although this is easy to bypass.
After downloading an app, control-click the file in your Downloads folder and select Open from the menu. You’ll get the same ‘unidentified developer’ warning as before, but this time you’ll have the option to open the app anyway.
You can reduce the frequency of these alerts by going to System Preferences > Security & Privacy > General. Click the padlock and enter your administrator password to unlock the settings, then choose to “Allow apps downloaded from: App Store and identified developers.”
Update macOS and reboot your Mac to reduce issues
Update macOS to the latest version, unless it isn’t compatible with the app you’re trying to use. Developers typically list the recommended operating software wherever you download the app from.
Check for updates in macOS by clicking the button in the menu bar and selecting About This Mac > Software Update.
A reboot of your Mac is another effective troubleshooting tool. Shut down your Mac using the button in the menu bar, and leave it powered off for a minute or so before powering on again. After doing so — and allowing all the background processes to close down and start again properly — your Mac is likely to run with fewer issues.
Delete the app and then try to install it again.
Before deleting any apps from your Mac you should make sure you have a recent backup of all your valuable data.
It could be that the app, or the app installer, has become corrupt and this is why your Mac won’t install or update it. The only remedy for this is to remove the app from your machine entirely and download it again from scratch.
Close down any version of the app if it is currently running on your Mac by using the Quit [App] button in the menu bar. Then open Finder and go to the Applications folder, find the relevant app and drag it to the Trash.
You should check the Application folders for individual users on your Mac. This can be done by navigating from your Hard Drive > Users > [User Name] > Applications.
Empty the Trash, then restart your Mac and download the app again.
Temporarily turn off the firewall on your Mac.
The firewall does a great job of keeping your Mac safe, but it can sometimes get in the way of installing or updating other apps. You can turn it off in the System Preferences, but you should remember to turn it on again after so your Mac is not left vulnerable.
Go to System Preferences > Security & Privacy > Firewall. Click the padlock and enter your administrator password to unlock the settings, then click the Turn Off Firewall button.
You should also turn off any antivirus software, as this may also be interfering with app installations.
After your app installation or update is complete, remember to turn your firewall and antivirus software on again.
Restore your Mac to its factory settings.
This is something of a nuclear option, but it’s there if you want it.
If, after all the other steps listed above, you still can’t get your Mac to install or update apps, a complete factory restore may offer the solution. Doing so will erase all your data and reinstall the macOS, so ensure you have a backup first.
You should also be aware that the entire process can take quite a long time, upwards of six hours depending on your internet speed and how much data you have.
Problems with updating your apps
Recently, Mac users have experienced a new problem in the latest version of macOS Mojave. In this problem, users can’t update their stock apps such as Keynote or Pages. They need to click an accept button in their account, but that accept button doesn’t exist!

This doesn’t happen to everyone: some users can find the accept button without any problems. But if yours is missing, you can still update the app by deleting it from your Mac and downloading a fresh copy from the App Store.
The easiest way to delete an app is to move it to the Trash from the Application folder in Finder. Then it might be worth restarting your Mac before you download the app from the App Store again. And once you do, you’ll have the recently-updated version of it.
How to fix app problems in macOS Catalina
What to do if you can’t approve new apps in macOS Catalina
Another beta problem in macOS Catalina is the inability to approve new apps from the Security & Privacy System Preferences. We explained one way to do this above, but lots of users running the beta version of macOS Catalina have found it doesn’t work.
It seems the solution is to disable Gatekeeper temporarily while you install the new app. We strongly advise you to turn it on again afterward. You can do this by going to System Preferences > Security & Privacy, click to padlock and enter your administrator password to unlock it. Under Allow apps downloaded from: select Anywhere.
If there is no Anywhere option, open Terminal and enter the following command line:
Restart System Preferences and you should see the Anywhere option. You can undo this at any time using the command line:
Make sure you enable Gatekeeper again after installing your app, or you will leave your Mac vulnerable to attack!
What to do if you can’t update or sign in to the Mac App Store
If you’ve been test-driving macOS Catalina through Apple’s Beta Software Program, you might have experienced problems using the App Store on your Mac. Lot’s of users are unable to update or download new apps because the App Store doesn’t let them log in.
Despite entering the correct Apple ID username and password, the Mac App Store still appears as though they aren’t logged in. If this has happened to you, try the following user suggestions to resolve it:
My Macbook Won't Update Software
- Sign out of your Apple ID from System Preferences > Apple Account.
- Sign out of Apple Music by going to Account > Sign Out from the menu bar.
- Try downloading the apps or updates from a different user account.
- Update macOS Catalina to the latest beta version, or revert to a stable public release of macOS Mojave.
