[python-committers] Travis CI: macOS is now blocking -- remove macOS from Travis CI?

[Alex Gaynor]

If you find a macOS CI platform with more capacity, please let me know :-)

Travis has been totally underwater of late, but I don't know of any
alternatives; probably because operating a fleet of macOS builders is a
giant pain. You need Apple hardware, and it turns out you can either
purchase a trashcan or a mac mini, and neither of those is really designed
for a server farm.

If anyone here can magically whisper in Tim Cook's ear, can you ask him to
license macOS to AWS or Google Cloud or something?

:-(,
Alex
