space in iMac
Hi, I need more space for mi Mac. If I erase the photos on the Mac, Will I lose them in iCloud?
iMac 21.5″, macOS 10.15
Yes. The iCloud Library is a syncing service NOT an off computer storage facility.
If you want to save room on your boot drive move your Photos library to an external HD formatted as shown in this screenshot and run it from there.
