I am getting messages about xcrun when I try to run off standalones from LiveCode, and do NOT want to bung my SSD full of xCODE, JUST install the command line tools: is this possible?
I did file a bug with apple for Big Sur. This is a know issue/bug with Big Sur update until Big Sur 11.3 beta3.
Good news with Big Sur 11.3 beta 3 update it's fixed.
