Clarification on iCloud Photos
So I've read a few articles on iCloud Photos and generally understand how this works, but have a couple of queries I can't find the answer to. As background I have an iMac running High Sierra (max it can get), iPhone, iPad both on iOS 14 and Apple TV 4K.
- All my photos in Photos on the Mac have titles, descriptions, keywords etc associated with them. If I turn on iCloud Photos on all these devices, does all this metadata also sync to the cloud, so that they would be visible on other devices as well?
- I'm planning on getting a new iMac next year to replace my current one. When this happens, would I restore the Photos Library to the new iMac from Time Machine/other backup, or would I simply turn on iCloud Photos on the new Mac and let it repopulate from the cloud? Or would either method work? Are there any advantages/disadvantages to either method? If I repopulate from the cloud, would all my titles, descriptions, keywords etc remain?
Thanks in advance for any advice.
