Not supported of course, but Parallels posted blog showing High Sierra running in Parallels:
Running the High Sierra Developer Beta in a Parallels Desktop virtual machine
Here is a screen grab in case they pull the article:
We've been trying to get this to work, but haven't been successful.
As of macOS High Sierra 10.13 Beta 5 and later, there doesn't seem to be a checkbox to prevent the drive from being formatted to APFS.
So install consistently fails, it can't get past drive verification.
So we know, not supported, but, they blogged that it is (or was?) possible.
Anyone been able to get this to work?
- Clone a 10.12.6 OOB VM.
- Enroll the VM in Developer Seed.
- Download High Sierra Beta installer.
- Run High Sierra Beta installer.
- Verification fails on each attempt, only boots back into Sierra.
PS, not for nothing but the much superior VMware Fusion Pro 8 does this without breaking a sweat...but I digress...not an option here unfortunately.
TIA,
Don
