Phase One has just released Capture One 20.0.1 for Mac.
Capture One 20.0.1 fixes an issue with tethered shooting on MacOS Catalina 10.15.2.
Plus, there are two additional bug fixes:
• Fixed an issue where using the Color Editor sometimes caused Undo to break.
• Fixed an issue where a default Catalog would load on start-up instead of the previously used Document.
