Can't access Photos to use as Screensaver/Desktop
I'm using El Capitan 10.11.6 and have been having trouble accessing Photos using Photos 1.5.
Most recently, when trying to set a new desktop background or screensavers, I can choose the Photo Library as the source and see all the folders, but when I select a folder, no images are shown.
This also happens if I ever try to attach a photo in an email (using Gmail in Chrome). I select Photos in the left menu bar, the folders show up, but when I select a folder, no images appear to select.
Yet, when I am in the Photos app, I can see everything. So I end up doing all these shortcuts, dragging photos to desktop or elsewhere and it's a pain. The PHOTOS app settings are set to use the iCloud Photo library and I am on wifi when trying to do all this. The "optimize Mac Storage" is also enabled, as is the "my photo stream."
Any tips appreciated. I've read all sorts of forums and can't find a solution. I did try this one thing where I typed in these commands but nothing happened.
cd ~/Pictures
ln -s iPhoto\ Library/Originals Originals
