I’ve a Macbook Air mid-2013. The unique SSD drive had Catalina and was working intermittently, so I made a decision to alter it. I acquired a third-party SSD drive of the identical measurement, and the corresponding adapter to have the ability to plug it in. It comes from a Home windows machine, so after I begin booting it begins loading Home windows, which means that the drive is efficiently acknowledged.
I’ve a bootable USB drive, creating utilizing this information, that incorporates Catalina. Nonetheless, it does not boot, displaying as a substitute a circle with a line via it…
Now, utilizing the command+R choice on this scenario masses the OS this laptop got here bundled with, specifically OSX 10.8 (Mountain Lion). The issue is, this model of OSX is not in a position to acknowledge this SSD drive. It does not seem in Disk Utility, as an example. So I can not set up OSX Mountain Lion from it. I consider this is identical cause the USB drive is booted to a circle with a line via it.
Utilizing choice+command+R masses macOS 11 (Large Sur), and this can be a new sufficient model that it sees the SSD drive. So I may set up this model. Downside is, I consider this model is simply too new for it to run easily on this older gadget, so I wish to set up macOS 10.15 (Catalina) as a substitute.
How can I obtain that? Can I someway use the terminal on this Large Sur Restoration Mode to put in Catalina to my SSD from the USB drive?
