Just downloaded zwift on my Mac. When I launch Zwift I get the error message 'Zwift encountered the following Error Code 23 in file/patcher.cpp at Line 512 and will close.

Any ideas?

Hey Seamus - did you get a solution to this?  
I have the same and am having little joy with Zwift Support ☹

Hey for anyone experiencing the same issue, I solved it by freeing up enough memory for the app, since my mac was almost full (used CleanMyMac)
