Bumping this thread because I spent 30 minutes pulling my hair out on this. Someone correct me if I'm wrong, but it used to be the case that you could have *both* "iCloud Photos" *and* "My Photo Stream" enabled, right? I seem to recall articles even having been written that suggested that it wasn't a bad idea to use both.
On my wife's 2018/2019 (I forget which) MacBook Air that I looked at earlier today, I'm fairly positive that she had both options available to her inside of the Photos app's Preferences/iCloud settings, whereas on my 2019 MacBook Pro 16, if I select "iCloud Photos", then the option for "My Photo Stream" disappears. If I uncheck "iCloud Photos", then the "My Photo Stream" option reappears. If that's the intended behavior now, then OK, but why are they using check boxes instead of radio buttons for these options, if they're now mutually-exclusive?
I just upped my iCloud storage to 2TB, so I guess I should just enable iCloud Photos, right? If so, I'm pretty sure that I also want to check off "Optimize Mac Storage" instead of "Download Originals to this Mac" as I don't want my MacBook's SSD to get filled with my entire photo library. Does this sound right?
Or are there still use cases where I might want to instead enable "My Photo Stream" on my MacBook?
Assuming that I'm OK using "iCloud Photos" in conjunction with "Optimize Mac Storage" then how would I go about uploading old photos I might have on a hard drive to iCloud, such that I don't have to keep them stored permanently on my MacBook?
