Hi @TonyT1,Is anyone seeing issues with this? Does Parallels have a beta group to test upgrades for High Sierra?
Hi @PaulS25, yes! You are correct. Our development team is working with the APFS file system and we will update you via the same article.Hi,
VM's on APFS filesystems went bad - corrupted and became unbootable there is a KB on this http://www.kb.parallels.com/en/123840
Restored them back to an HFS+ second disk and all has been OK with them so far.
I have had a couple of crashes and sent the reports into Parallels but nothing major when running from HFS+ filesystems.
Thanks
Hi @TonyT1,
Parallels Desktop 12 for Mac does not officially support High Sierra that has been made available as a beta yet. We are closely working with Apple on providing official support for High Sierra.
We recommend you to wait for an update of Parallels Desktop 12 for Mac that will be available with High Sierra. Subscribe to http://kb.parallels.com/123948 to know when a new update is available.
Parallels Desktop 12 will support High Sierra when it is officially released and we can only know the types of Guest OS's supported after that. If you are using beta version of High Sierra and facing any issue particularly with 32bit virtual machines, share it with us.Has Parallels said anything about providing 32 bit support (XP, Snow Leopard Server) on High Sierra? Are all VMs going to have to be 64 bit?
The latest build of High Sierra, unlike the previous one, somehow doesn't even allow the "System Preferences > Security & Privacy > General" panel to display "Parallels, Inc" so I can click on "Allow." I'm using Parallels Desktop 12.2.1 (41615). It doesn't get past the warning as indicated in the screen shot.

Hi @megavolt17,Same here (I think as what you are saying).
There is no mention of Parallels, nor an option to "allow" using itView attachment 12722
Hi @KatiaF, thanks for the suggestion.Try downgrading to 12.2.0. That worked for me.
Hi @megavolt17,
As macOS High Sierra is not officially released it is not supported by us. You can try disabling System Integrity Protection and check if you can use Parallels Desktop.
Follow these steps to disable SIP:
Parallels Desktop 13 will support, after High Sierra is released officially.Is version 13 of PD is ready for macOS X High Sierra?
