MP 7,1 Help I need to restart on Big Sur from Catalina

[machenryr]

I was trying to open an older disk on mavericks. I can’t see it. I recalled that there was a trick. So I restarted under a test SSD I set up with Catalina. Now I can’t find my Big Sur SSD to restart under my home main OS. Help. I’m sure it’s a simple solution but I ding remember what it is!

Does the Big Sur SSD appear in the Option/Bootpicker screen when you restart, holding the Option key?

I’ll try that. It doesn’t appear. But I’ll try the option key. Right now I’m updating Catalina. If I need to I’ll upgrade this to Monterey since this was designed to be my test drive.

Thank you! That’s what I had forgotten. Age. Damn. Lol.

Damn it. It’s me again with the same problem. Now I’m going from Catalina back to Monterey. Mac Pro (2019). I had to find something on the Catalina SSD. Now I can’t see the home Monterey SSD. I’m holding option on restart but I’m not seeing anything. Help.

I got it. I knew I would. I wasn’t waiting for the Apple splash screen. Whew.
