I have an external disk that should be unmounted (NOT ejected) except for a short time each day to run a CCC backup. Unfortunately, CCC often fails to unmount the disk, and my manual unmounting script fails with this message:
Volume 2propstore on disk8 failed to unmount: dissented by PID 3270 (/System/Library/PrivateFrameworks/PhotoLibraryServices.framework/Versions/A/Support/photolibraryd)
It’s a pain to have to deal with this, sometimes several times each day. The only way to unmount the disk is to find the PID of
photolibraryd and manually kill it.
photolibraryd seem to say that it’s analyzing and indexing my photos for iCloud Photo Library and photo streaming. All iCloud services are turned off in Internet Accounts and I’ve never used photo streaming (I don’t ever even use Photos).
Why is Apple running tasks that are poking around in my external disk in the first place, to index photos for a service (iCloud) that I have specifically disabled? In addition to annoyingly preventing me from manipulating my disks the way I want, it seems creepy and intrusive.
Any thoughts as to how I can modify this behavior?
