Greetings,
I was doing some debugging today and I noticed that
FSEventsCopyUUIDForDevice() occasionally returns a different value for a
given device. The frequency varies, but the UUID seems to change about
every week or so. This apparently has been going on for years.
Is this expected behavior?
I would have expected the UUID to be more persistent. I certainly
haven't reformatted my drives or anything, and I notice that the event
ID haven't rolled over either. Are there other reasons why the UUID
isn't stable (on my system)?
Thanks,
James
