Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

I kept my photos library on an external ssd for quite some time - and everything went well. Since update to OS 15.5 I get "Photos unable to open library "Photos Library" (4302). If I create a new library (just to test) - the same happens.

Hi


Regarding the external SSD - is it correctly formatted for a photos library?

It must be formatted APFS or MacOS extended (journaled) (preferred for spinning drives)

It Must not be (or have been) used for time machine. (A time machine drive can be used if re-formatted)

It must have the 'ignore ownership" checkbox ticked.

It must be directly connected (No ethernet or wifi)
