I just installed a MacOS high Sierra guest on a MacOS high Sierra host on Parallels 13. Parallels tools in place and everything works. The host is a Mac Pro with 6 cores and 16Gb RAM. But why is the guest so slow? I've tried everything. I checked all processe in both host and guest, nothing strange, I assigned unlimited resources, 4 processors, 8Gb RAM and rebooted but it changes nothing. Watching a movie (a locally stored avi file) is very painful but only 34% guest CPU is used. I resently had an Ubuntu guest in Parallels 12 and it was fine. What more can I do? If it can't be faster Parallels is no use and I'd like my money back. However, it has worked in earlier releases.

Downgraded to Parallels 12 and a Sierra guest. Better, but still too slow to use. Anyone?I just installed a MacOS high Sierra guest on a MacOS high Sierra host on Parallels 13.

It seems Parallels' top priority is Windows guest (sells the product!)
Other uses seem to be an afterthought...

I guess you're right. Such a shame, I'd rather run a virtual MacOs guest instead of windows for my needs.It seems Parallels' top priority is Windows guest (sells the product!)

Hi, I'm sorry, nothing helps.
Seems like there are several users having the same problem, no solution in place. Maybe it is time for a developer to dig deep into this issue.
- Underpowered hardware - I have a Mac pro 3.7Ghz, 4 cores, 16b RAM (4x4) and 500Gb SSD. No performance issues at all.
- Using an outdated Parallels Desktop version or build. - Latest OS and latest Parallels. Even tried to downgrade, same problem .
- Too many resources assigned to the virtual machine. - I have tried different settings, low resources and high resources. Same result.
- Multiple anti-virus programs installed - No anti-virus installed.
- Malware (virus) presence in operating system. - No detectable virus
- Too many or conflicting startup items. - 3 non-conflict startup items, tried wirg only one as well, no difference.
- Too many virtual machines are running. - Only one virtual machine running.
