I've received confirmation that my Mac Mini will continue to be supported and 
allowed in our labs for at least one more year, maybe two.

Therefore, the only problem I will have is the lack of a new SDK and compiler.

So, asking again to the Mac team: how long will you take patches to make 
things compile with Clang-Xcode 17 and the MacOSX26 SDK?
