Contrary to Apple's promises to ensure the most stable operation of macOS Catalina on all compatible devices, regardless of generation, only a day after the release of the update on the Web, there were a lot of complaints about the failures brought by the current macOS Catalina version.Why won't macOS Catalina install on my Mac?
This problem begins with the introduction of many users with macOS Catalina. And although the result of all, faced with it, one, causing its causes may be very different.Firstly, the macOS Catalina download may stop due to the lack of disk space, because the update requires at least 6 GB if you upgrade from Mojave or 23 GB from High Sierra.
