#21633 (Bug) “Main – DisplayCal is already running” Cannot launch DisplayCal on Mac 10.15.2
After installing 22.214.171.124 I was first prompted upon launch to give screen recording permissions which I approved. Then it wanted me to quit and relaunch for them to take effect. I was about to when DisplayCal requested to install Argyll automatically via download, which I cancelled because I already had it downloaded. So I chose the directory and clicked Okay when it froze and I had to force quit. Upon attempt to relaunch it gave the error DisplayCal is already running. I checked the force quit application menu, nothing there. I check the Activity Monitor for any DisplayCal processes, nothing there… Rebooted the Mac. Same Message on launch… I uninstalled all Displaycal files, restarted the mac, and reinstalled. Same error. I simply cannot properly launch displaycal.
