I have Mac Sequoia Beta 3 (24A5289g) running in a Parallels VM. I tried to sign in my Apple ID in the VM's Mac App Store and still get an "unknown error" like before. Is this working/not working for anyone else? I thought beta 3 was supposed to enable this feature
Apparently, the host needs to be Sequoia beta 3 as well ... check this article and the comments (https://eclecticlight.co/2024/07/12/sequoia-virtualisation-and-apple-id/).
