I am using Delphi 10.4.2 Pro. For some odd reason, I cannot see the SDK option for MacOS! Shown in the picture. Could someone help with it? The Mac System are both 10.15.7 Catalina and BigSur. The PA is the latest version 12.2.10.3. Obviously, this something wrong with Delphi side.
As Dave Nottage & fpiette pointed out above. My installed package data file is damaged when I Delphi menu / Tools / Manage Platforms . Have to reinstall Delphi. Problem solved. I also noticed MacOS platform is auto selected when install Delphi. Have to manually check it. thanks guys.
