Photos Library transfer back to Mac from External Hard Drive
Years ago I transferred my Photos Library.photoslibrary to an external hard drive to save space on my iMac. I now have a new iMac running Big Sur. I'm having a lot of problems running the Photos program from the EHD and would now like to move it back to my computer in the hopes that it will run more smoothly. I tried to copy/move it to the Mac "Pictures" folder, then later when that didn't work I tried to copy/paste it, but neither way worked. The 30 minute copy job would appear to be working, then with about 3 minutes left to go, it would stop and say it couldn't finish because there was already a file called Photos Library.photoslibrary. There is no file in Pictures on my computer called that. The only place that file exists is on my EHD. Does anyone know how I can get this move/copy/transfer accomplished?
