I'm trying to install Yosemite on a Parallels 16 VM. I downloaded the Yosemite installer .dmg from Apple's legacy OS page. When I create the new VM and point it to the .dmg, it says it can't detect the os. I click continue anyway, and then get to the UEFI Shell. I've connected the installer .dmg as a disk image, but I'm not sure how to proceed from there. Any advice is appreciated!
I have Yosemite installed on a Parallels 16 VM. It was a very laborious process. I went around and around with lots of combinations and eventually this is what worked. This could probably be optimized, though. 1. Downloaded Yosemite InstallMacOSX.dmg installer from the Apple Legacy OS page. 2. Created a MacOS VM using the recovery partition (for me it's Big Sur). 3. From within the Big Sur VM, I ran the InstallMacOSX.pkg, which created an "Install OS X Yosemite" app in the Applications folder. (I ran this in the VM because I didn't know what it would do and if it would mess-up my host machine) 4. Copied the Install OS X Yosemite app to the Host machine. 5. Now I created a new VM with GuestOS option and drag/dropped the Install OS X Yosemite.app to start the process. It did say it needed to create a bootable disk image and I gave it a name and location, and everything worked. 6. For some reason, I felt like I needed to keep the Configuration settings unlocked while creating the VM. Seems like a previous attempt it said something like it needed access to the host credentials??? I forget. This whole process seemed way more painful than it needed to be.
