10.12- Screensaver question- Photos not a choice I recently updated to 10.12 - Sierra- and migrated iPhoto to Photos. In the system preferences I do not see a choice to select Photo library. In the source panel I just see National Geographic/Aerial/Cosmos/Nature patterns. I would like my photos to be my screensaver.
Any help?
I have just spotted an older (2012) answer at this link:

However it suggests clicking and holding the "Screensaver" tab, which didn't work for me.  But clicking and holding the "Source" drop-down menu button did work for me - up comes an option to use "Photos" but if you choose that, you can then choose between the "Photos" app and "iPhoto" app. This is a better solution than the one I just posted, I think.
