Catalina macOS is currently in beta version for developers but also for users who want to test the future operating system, what will be officially launched this fall by Apple.

We tested Macos Catalina Beta on a MacBook Pro 13-inch, Mid 2012, and everything went unexpectedly well, until a UPDATE OF MACOS. Following the Required Restore by UPDATE, MacBook was stuck with a screen that informs that the version of macos cannot be installed.

The only option given in the information screen, which unfortunately does not solve anything, is the button on the screen "Restart“.

Most of the time, "macOS could not be installed on your computer"It is given for two causes:

Everything is indicated after the disk is cleaned of everything. Formatted. Of course, before you start this step, you need to have a data backup.
