Julia: Problem Loading Mac Application (1.3) on Catalina

[arnavs]

Discussed this with @ararslan.

Loading the app gives:

Last login: Thu Jul 25 12:11:46 on ttys000
exec '/Applications/Julia-1.3.app:/Contents/Resources/julia/bin/julia'
arnavsood@mbp:~$ exec '/Applications/Julia-1.3.app:/Contents/Resources/julia/bin/julia'
-bash: /Applications/Julia-1.3.app:/Contents/Resources/julia/bin/julia: No such file or directory
-bash: exec: /Applications/Julia-1.3.app:/Contents/Resources/julia/bin/julia: cannot execute: No such file or directory
arnavsood@mbp:~$ 

There shouldn't be a colon. Remove it and it's fine (i.e., the actual binary embedded in the app works fine.)

I have an unfounded hunch that it could be a change in AppleScript new in Catalina that affects this line: https://github.com/JuliaLang/julia/blob/master/contrib/mac/app/startup.applescript#L3.

cc @simonbyrne, who IIRC has done a fair bit with the .app packaging on macOS.

Looks like an applescript bug. This discussion suggests it was fixed in the latest beta.

@arnavs it would be great if you could try out the latest beta to confirm.

[arnavs]

Thanks @simonbyrne, will update and report back here.

[arnavs]

Yeah, this disappears on Beta 4.

Thanks for investigating.
