XCode 11.1 install fail XCode 11.0 update installed automatically under MacOS 10.14.6 and works fine. After MacOS 10.15 (Catalina), XCode 11.1 update repeatedly fails to install after downloading. Version 1.0 still works under MacOS 10.15 however. What am I doing wrong? Is it me or Apple? iMac (Retina 5K, 27-inch, Late 2014)
