Doesn't run on macOS Catalina 64 bit

[sfcgeorge]

I suspect Self wasn't compiled with 64 bit only support because it doesn't do much on macOS Catalina.

The "Self Control" (oh I just got the pun) GUI runs, but selecting a snapshot does nothing / flickers in "Running worlds" for a second. So the GUI is fine but something deeper isn't happening.

Running Self on the command line produces this weird message

/usr/local/bin/self: line 2: /Applications/Self Control.app/Contents/Resources/Self.app/Contents/MacOS/Self: Bad CPU type in executable

Which I think might mean it was compiled 32 bit only since Catalina is 64 bit only.

Yes, Self is currently 32 bit only. The VM needs to be ported to 64 bit and a 64 bit JIT compiler implemented.
