I recently updated MacOS, and now when I launch Parallels 17 Pro [v17.0.1 (51482)], I immediately get a pop-up window saying "Access denied." followed by "You do not have enough rights to use this virtual machine.". The Pop-up does provide a link to a Parallels Knowledge Base article (https://kb.parallels.com/en/5796) which indicates checking read/write permissions and ownership for the .pvm file, but mine appear to be set correctly. It also suggests using the 'chmod" command to change permissions on directories/files, but macOS will not allow me to do it (I get two identical messages saying "Unable to change file mode on <file-name>: Operation not permitted). This all worked fine a couple of days before the macOS upgrade. I originally tried this with Parallels v17.0.0, and when it failed, I checked for a Parallels upgrade (which was available) and installed it - same problem. The macOS upgrade was to Monterey 12.0 (21A5522h) from an earlier version of Monterey 12.0. IF anyone has some thoughts, they would be appreciated. Thanks.
