stuck in loop with restore_ports.tcl migrating to macOS Sierra (10.12.1)

[Ken Cunningham]

Hi Murray,

Just to tell you I have not touched a thing on this Sierra install, and it works fine for me.


(Did you have a beta installed? Can you think of any reason why your SDK might not be stock?)

It takes 5 minutes to reinstall Xcode and the command line tools. That would be step 1 for me, but it's up to you.

Ken
