Aloha everyone, I was wondering if I was alone in this regard. I am currently in grad school and am a bit anal about keeping all my school files on an external HDD. That way, I can plug my drive into either my main iMac or my MacBook Pro and work on the same source document. I have noticed, however, that even though my drive was formatted exactly like the ones in both my primary Macs, I am unable to use Versions. I get a prompt indicated that Versions is not supported on that volume. I have plenty of room on my external HDD and it is HFS+ Journaled, so I fail to understand why it can't support Versioning. Am I misunderstanding something here, or is it simply because it is an external HDD? Has anyone else experienced this behavior?
