VMware tech support recommends users of VMware Fusion not install the latest version of macOS, released July 15. The combination inevitably crashes the Mac they’re running on.

VMware Fusion makes it easy to run Windows or Linux apps right alongside Mac apps in macOS. But it doesn’t cooperate with macOS 10.15.6.

macOS 10.15.6 and VMware Fusion don’t cooperate

Reports of crashes were submitted to VMware support forums. After some debugging, the company reports that the problem is in the newest macOS update. A bug report has been submitted to Apple.

Unfortunately, there’s not much else the company can do at this point. “We have not yet identified any workaround other than refraining from installing macOS 10.15.6, which is a bit painful (and the advice will come too late for anyone who finds this thread because they are already running into this problem), or shutting down your VMs whenever you aren’t using them and rebooting your host every day or every few hours or every hour, which is … ugggggh,” said VMware engineer Darius in the forums.

Otherwise, All the company can do is urge Apple to introduce macOS 10.15.7 with a fix for this bug.
