Simultaneously with the first public beta version of iOS 13, the Coopertinos released other public test builds. For example, macOS 10.15 Catalina. Now everyone can try out a new apple platform. However, so far the first public beta is not very suitable for everyday use.
However, if some flaws, periodically departing applications and some “thoughtfulness” of the system do not confuse, then install macOS 10.15 Catalina Public beta 1 is easy enough.
The main thing to do before installing a public test build is to back up the system through Time Machine. Without a backup, you can’t go back to macOS 10.14. This is especially true for Mac owners with a T2 chip.
1. Connect the external hard drive to the Mac. Ideally, it should be equal to or larger than a Mac. 2. Open System Settings – Time Machine.
3. Click on the Select System Drive item. 4. In the open window, choose an external drive. If it is formatted in an inappropriate form, it will have to be formatted first.
5. After selecting a backup disk, the utility will start copying the data.
Recall that macOS 10.15 Catalina is not compatible with all Apple computers. You can install a new operating system on:
• MacBook (Early 2015 or newer) • MacBook Air (Mid 2012 or newer) • MacBook Pro (Mid 2012 or newer) • Mac mini (Late 2012 or newer) • iMac (Late 2012 or newer) • iMac Pro (2017) • Mac Pro (Late 2013 и mid 2012).
– Go to Apple’s official website, a special page dedicated to the beta program of Apple operating systems. Click on the Sign up button and enter your Apple ID.
