I just upgraded to MacOS Big Sur. I've never used the Screen Resolution tool before the upgrade so I can't say if it worked previously. I thought I'd give it a try to manage my resolution on three monitors. When I click the icon, nothing happens. No application launches, nothing! No errors either. What I've tried so far: 1. Logged out and back in 2. Rebooted my mac 3. Uninstalled Parallels Toolbox and reinstalled Has anyone else encountered this issue and if so, what was the resolution?
