If there are several solutions to fix this error and successfully install macOS on your computer. In this article, we will discuss some of the most effective solutions to fix the “macOS could not be installed on your computer” error.
Before attempting to install a new version of macOS, it is important to check if your Mac is compatible with the latest version.
Apple provides a list of supported Macs for each version of macOS on their website. If your Mac is not compatible with the latest version, you may need to consider upgrading your hardware or installing an older version of macOS.
Free Up Storage Space
If your Mac does meet the compatibility requirements for the latest version of macOS, the next step is to check if you have enough free space on your hard drive. Upgrading to a new version of macOS requires a significant amount of storage space.
It is important to free up as much space as possible before attempting to install the new operating system. You can use the built-in Disk Utility app to check how much free space you have and delete any unnecessary files or apps.
Restart Your Mac
Sometimes, a simple restart can fix the “macOS could not be installed on your computer” error. Restarting your Mac can clear any temporary files or settings that may be causing the issue. To restart your Mac, simply click on the Apple menu in the top left corner of the screen, select Restart, and wait for your Mac to reboot.
Boot into Safe Mode
If restarting your Mac does not fix the issue, you can try booting your Mac into Safe Mode. Safe Mode disables any third-party extensions or apps that may be causing the issue and allows you to perform basic troubleshooting.
To boot your Mac into Safe Mode, restart your Mac and hold down the Shift key as it boots up. Once your Mac is in Safe Mode, try to install macOS again.
Reset NVRAM or PRAM
NVRAM (non-volatile random-access memory) or PRAM (parameter random-access memory) are types of memory that store settings for your Mac. Sometimes, resetting NVRAM or PRAM can fix issues like the “macOS could not be installed on your computer” error.
To reset NVRAM or PRAM, restart your Mac and hold down the Command + Option + P + R keys as it boots up. Keep holding the keys until you hear the startup sound twice, then release the keys and try to install macOS again.
Create a Bootable Installer
If none of the above solutions work, you can try creating a bootable installer for the latest version of macOS. A bootable installer allows you to install macOS from a USB drive instead of downloading it from the internet.
To create a bootable installer, you will need a USB drive with at least 12 GB of free space and the macOS installer app. Follow the instructions on Apple’s website to create a bootable installer and use it to install macOS on your Mac.
In conclusion, the “macOS could not be installed on your computer” error can be frustrating, but there are several solutions to fix it. By checking compatibility, freeing up storage space, restarting your Mac, booting into Safe Mode, resetting NVRAM or PRAM, or creating a bootable installer, you can successfully install the latest version of macOS on your Mac.
If you are still having issues, it may be best to seek help from Apple Support or a professional technician.
