    Need some help. Updated to 10.12.3 this morning, and can't open PDF's in preview, which is a big issue for me as I handle a lot of PDF's. They want to all open in Photoshop CC. I uninstalled Photoshop CC, now they open in Safari. ??? I go to open manually in Preview, and it just doesn't do anything with the command, like I didn't even ask it to. Doesn't hang or anything, just doesn't open it and gives no error. I tried deleting and that didn't work. I created a new user account to see if I could open them in there, and Preview will open PDF's there! I would really like to not have to migrate to a new user account if it can be avoided.

    BTW - I can open jpeg's in Preview without issue.

    Do a Get Info on a PDF. Change to Open with Preview. Then select Change All.

    I've done that, and I've also tried manually opening the files and it doesn't do it. Thanks though.

    I tried that too, no luck. Thank you for responding!

    Fixed It!! I downloaded Onyx, and went to Maintenance -> Rebuilding tab, executed the task and everything went back to normal. :)
