Hello @CenkK , Parallels Desktop 11 does not support High Sierra, it may or may not work. We would recommend you to upgrade to Parallels Desktop 13 which officially supports Mac OS High Sierra. Thanks
Actually I already tried and it works well with different type of VMs (Ubuntu, Win7, WinXP, OSX) but have trouble to work with Bootcamp, so finally ended up with PD 13
Just started to use P11 with High Sierra. All works fine except the full screen scrolling graphics artifacts issue that is also present in P13. It is suppose to be fixed in next Mac OS release revision.
Hi @tbirdvet, yes, we are aware of this issue. We have already forwarded the request to the Engineering team and we will let you know once we have an update regarding this. Thanks!
