Ah of course! > git pack-refs --all Yeah that "fixes" things so you get `fatal: invalid reference: MASTER`. I guess `git checkout` checks whether `MASTER` exists (yes, according to MacOS), but git log checks whether the current branch (`MASTER`) matches `master` (it doesn't). Very unfortunate, but I guess it's not worth fixing.
