Exciting a new version of macOS is exciting. But it can quickly become frustrating if, instead of being presented with a brand new Mac, ready to use, you see an error message like “macOS could not be installed on your computer.” Fortunately, there are lots of things you can do to fix the problem, so let’s get started.
Before you try to install a new version of macOS
It’s essential that before you perform any major upgrade, say from Mojave to Catalina, that you backup your Mac. One of the steps described below involves a complete reinstall of the operating system, which could result in you losing data. It’s best if you can do the backup using Time Machine, as you can then use Recovery Mode to restore your Mac from the backup. But if you don’t want to use Time Machine, create a bootable clone of your startup disk using a tool like SuperDuper or Carbon Copy Cloner.
Why does “macOS could not be installed on your computer” appear?
There are a number of reasons you might see this error message. Here are some of the most common.
Before you try to fix the error
Check if your Mac is compatible with the version of macOS you’re trying to install. The best way to do that is to launch the App Store app, search for the macOS version you’re trying to install and scroll down the Compatibility section. You should see a message that says “works on this Mac”. Alternatively, go to Apple’s website support pages and search for the minimum system requirements. You might need to reboot in Safe mode, see below, to check because if you do a normal restart, your Mac may immediately launch the installer again.
How to fix “macOS could not be installed on your computer”1.Restart your Mac in Safe mode
Safe mode disables startup items, launch agents, and everything else except the bare minimum macOS needs to function. Restart your Mac from the Apple menu or by holding down the power button, and press Shift until you see the Apple logo.
2. Try running the installer again while in Safe mode
If the problem was that launch agents or daemons were interfering with the upgrade, Safe mode will fix that. If it works, you should restart your Mac normally after the installation and remove any launch agents and daemons you don’t need.
The simplest way to remove launch agents is to use CleanMyMac X.
Here’s how:
3. Free up space
You’ll need up to 20GB of free space on your main drive to download and install an update to macOS. If you don’t have that much free space, it’s time to clear out the junk and free up space. I’ve found that the quickest and easiest way to do that is to use a popular app CleanMyMac X by MacPaw. It can free up tens of gigabytes of space with a couple of clicks.
Install CleanMyMac X, then launch it — download free edition here.
4. Reset the NVRAM
The NVRAM on your Mac stores data even after your Mac shuts down or restarts, unlike regular RAM which is flushed every time you restart. NVRAM persists, thanks to a small amount of power supplied by your Mac’s internal battery. Resetting NVRAM rarely has any effect, but it can do in some situations, and as it won’t do any harm, it’s worth trying. It’s quite tricky to do, so you might need some help.
Restart your Mac while holding the Command + Option (Alt) + P + R keys and wait until you hear a startup chime. It may take a little longer than normal to restart, and may restart twice, but once it’s done, the NVRAM will have reset.
5. Try the combo updater
If you can restart in Safe mode and quit the installer, try downloading the combo updater from Apple’s website. The combo updater contains all the files necessary to install macOS on all Macs, whereas the version downloaded from the App Store only has the files for your specific Mac. It may be that the combo updater works, where the Mac App Store version doesn’t.
6. Install in Recovery Mode
This is the last resort, if nothing else works.
There are a number of things you can do to fix your Mac when you see the message: “macOS could not be installed on your computer.” If the problem is that you don’t have enough space, you can use CleanMyMac X to get rid of files you don’t need. Otherwise, go through the above steps one at a time until you’re able to install a new version or update to macOS.
