Xcode 12 GM seed uses 100% CPU Just downloaded the new "Xcode 12 GM seed" released Sept 15, and it constantly uses 100% of my CPU. I didn't have this problem with Xcode 12 beta 6. I'm on a MacBook Pro 2018, macOS 10.15.6. Anyone else experiencing the same problem? Developer Tools & Services Xcode Xcode 10 0 2.5k Sep ’20
