Another different failure on "bolen-dmg-3.x". I don't understand the "RuntimeError: command failed: make" error :-(

The macOS Tiger buildbot where all of these "too many files open" OS failures occurred has been retired.

> The macOS Tiger buildbot where all of these "too many files open" OS failures occurred has been retired.

macOS Tiger is still supported, since we still have x86 Tiger buildbot, it's just the dmg buildbot on Tiger which has been retired. Right?

Whether or not Tiger is supported, we no longer have any Tiger buildbots. We agreed to retire them earlier this year.
