Why is Mac OS creating a "Photos Library.photoslibrary" on my desktop every time I restart?

I have my system "Photos Library.photoslibrary" on an external SSD drive. Every time I restart, Mac OS (Sequoia 15.5) creates a "Photos Library.photoslibrary" on my desktop with "Zero Bytes" in Get Info. I checked the Photos.app Settings and it still shows the correct Library Location on my external SSD drive.


How do I prevent MacOS from creating this Library every time I restart?

iMac (2017 – 2020)

The problem is that an additional library is being created on the desktop after a restart.

Try this:


Option-launch Photos.app and let it create a new empty dummy library to its default folder in your internal disk's home folder at ~/Pictures and then ignore that dummy library's presence.


Then Option-launch Photos.app and navigate and open the system library from the external disk (or just double-click in the Finder to open it).


Does Photos then still create a new library to the Desktop after a restart?

This usually happens when you get a new Apple device & don't turn off share photos which is automatically on. Photo sharing needs to be turned off on all devices. This hopefully hails the external SSD. To delete the annoying file rename it & change the extension. Photos Library.photoslibrary to whatever name you you chose mine was rude & make the extension .jpg or some other extension & it will let you delete

It's not about what "didn't work". I have checked all of the settings in Photos. Restarted. Restarted in Safe Mode and then restarted again. Shut Down and then started up again. It seems to be something with the OS and having the photos library on an external drive.


I am an expert Mac user. I do a lot of programming and am very comfortable in Terminal. I was simply wondering if anyone else has experienced this and if there may be some type of underlying plist or something that I can tweak to stop this behavior. I'd even be fine with the Finder just hiding it from view.


It does not affect performance, it's just an annoyance.
