Why am I seeing the ‘macos could not be installed on your computer’ error message?
Recently, I attempted to upgrade or reinstall the operating system on my Mac, and I was greeted with a frustrating message: ‘macos could not be installed on your computer.’ This error has left me puzzled and unable to proceed with the installation. I double-checked my internet connection to ensure that it was stable and made sure that my Mac had enough free disk space for the new installation, yet the error persisted. I wondered if there could be an issue with the integrity of the installation files or possibly some compatibility problems with my existing hardware. Despite closing all other applications and even trying the installation from a different network, I continue to face the same obstacle. This repeated failure to install macOS is both confusing and inconvenient, and I’m not sure what the root cause might be.

I’ve been in this situation before, and an unusual cause I found was incorrect date and time settings. This can disrupt the installer. Here’s a way to correct it:
1. Enter Recovery Mode by restarting and holding Command + R.
2. Open Terminal from the Utilities menu.
3. Type date mmddhhmmyyyy (adjust to the current date), for example, date 102417302020 for October 24, 2020, at 5:30 PM.
After correcting the date and time, exit Terminal and try the install again. Sometimes, even the smallest details can stop the process, so ensuring accurate settings is crucial.
The error message ‘macos could not be installed on your computer’ can also signal issues caused by third-party software. I recommend booting your Mac into Safe Mode to isolate the problem:
1. Restart your Mac while holding the Shift key.
2. Release the Shift key when the login screen appears.
3. Log in (you should see Safe Mode displayed in the top right).
Attempt the installation in Safe Mode. This mode prevents third-party software from running, which can help the installation process by avoiding conflicts.
A common culprit for the ‘macos could not be installed on your computer’ error is the health of your Mac’s hard drive or SSD. Disk errors can impede the installation process. Here’s how you can check and potentially fix this:
1. Restart your Mac, then hold Command + R to enter Recovery Mode.
2. Open Disk Utility and select your startup disk.
3. Click ‘First Aid’ to initiate a check and repair for any disk issues.
After completing these steps, attempt the installation once more. This often resolves the problem when disk errors are at play.
One possible reason for seeing the ‘macos could not be installed on your computer’ message is a corrupted macOS installer. I’ve experienced this issue myself and found that re-downloading the installer from the App Store typically resolves the problem. Ensure you have a stable internet connection during this process to avoid any interruption. Once you have the fresh installer, try running the installation again and it should proceed smoothly.
