Mac CI is broken

[jrmuizel]

I seem to have to broken it to cause osmesa not to build:

So the
make[4]: /Users/tcworker/.cargo/git/checkouts/osmesa-src-bf84ce2b80210dd7/1cf8c2f/mesa-src/bin/install-sh: Permission denied error makes no sense to me.

/Users/tcworker/.cargo/git/checkouts/osmesa-src-bf84ce2b80210dd7/1cf8c2f/mesa-src/bin/install-sh exists and is executable by tcworker. In fact it is usually used in earlier stages of the build successfully.

I tried to see if it was being modified during the build using https://github.com/jrmuizel/fslogger but nothing showed up.

The cause of this as far as I can tell is logging in graphically using the tcworker.

I've since tried logging out. That does not help.

This seems to be working now. Please re-open if there is more work to do here.
