My MacBook refuses to update Catalina OS for a while now. Everything was fine until yesterday, when update reaches 90% and keeps being frozen at that percentage. I would restart the process, restart the computer, internet connection, everything, and nothing works. Where could be the issue since I am not even getting the error report on it?
Hello, check the below steps to resolve the issue.
- Check compatibility
If you’re using one of these computers with OS X Mavericks or later you can install macOS Catalina. Your Mac also needs at least 4GB of memory and 12.5GB of [available storage space] or up to 18.5GB of storage space when upgrading from OS X Yosemite or earlier.

- Make a backup
Before installing any upgrade, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available.
- Get connected
It takes time to download and install macOS, so make sure that you have a reliable Internet connection. If you’re using a Mac notebook computer, plug it into AC power.
- Download macOS Catalina
If you’re using macOS Mojave, Choose Apple menu > System Preferences, then click Software Update.
- Begin installation
After downloading, the installer opens automatically.
- Allow the installation to complete
Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar, or show a blank screen several times as it installs both macOS and related updates to your Mac firmware.
Hope this helps.
