According to the Applications page, all three Mac WW apps are working for "Mac OS 10.5+ running on an Intel 64-bit CPU".
My machines running Mac OS 10.13 fail immediately. Machines running 10.14 or higher work fine. Failing machine booted up on 10.14 works.
I vaguely remember reading a conversation regarding this (last year), but I cannot find it now. Are the Mac WW apps listed wrong on the Applications page?
