I have a 400GB Photos Library on my MacBook. These photos are in iCloud photos as well, and the originals on my Mac.
My Mac is only 500GB, so it was full, with only 10GB left. Now I bought a 1TB external SSD. What I did:
- In Photos I 'paused' the updating/downloading, because it seemed stuck. Probably not enough space to download the latest photos.
- Turn off the internet on my MacBook
- Copy the Photos Library to the SSD
- Open that Photos Library in Photos, and set it as System Library
Now it says "Uploading 72.xxx photos". I know it's probably not uploading, but checking if they exist in iCloud. At least that's what I'm hoping...
But it's terribly slow. So far it has been on for 3 hours, and it has gone through 200 items, of the 72.000. In Activity Monitor the network speed is at 0 most of the time, and every minute or so a very small peak in "Sending". With this speed it's going to literally take weeks to complete. Also I hope it won't get confused when suddenly there are new items available in iCloud that my iPhone has taken and uploaded in the meantime.
Photos seems to not be doing much at all. Is this normal? Is there any way to speed it up? Or would it be better to create a new Photos Library that will download all originals from iCloud? If I do that, what do I lose? The saved faces only (which I can regenerate of course)? Or is there more?
It seems a bit ridiculous that it goes through all the photos when I just moved the library to a different disk without making any changes. Waiting weeks is also something I don't like, as then the new originals form my iPhone are only in iCloud and not backed up to my Mac.
