Mac photos not uploading to Facebook
I can't upload any photos from my Applemacbook pro to Facebook. I've looked on previous articles and find that the option under photos/preferences/ shows the option to "use as system library" is greyed out and nothing I do will alter it. all my photos ar eon the machine, but there is no way to transfer them to FB. I'm getting totally fed up with computers not doing something they are designed to do simply. everything is over-complicated. I am over 65 and am fed up with technology. What is the easy way to fix the problem apart from smashing the computer to pieces?
MacBook Pro 13″, macOS 10.14
