Tossing this into the fediverse on the off chance someone is familiar with the problem and a fix.
My father is on a 2015 iMac (Intel Core i7) running macOS 12 Monterey.
PDFs are not opening properly, in a number of ways. This is the case for both Preview *and* Adobe Acrobat:
- If the app is not running, dragging a PDF over the app icon on the dock does nothing; the app doesn't launch.
- Double-clicking or selecting “Open With" from the contextual menu *will* launch the app and open the first document.
- Any successive documents will *not* open via double-clicking/the contextual menu/dragging to the dock.
- They will, however, be opened if “Open..." is selected from the File menu within the app.
- The same thing does *not* happen with TextEdit files or OpenOffice files - those apps behave normally and open successive files. It's just PDFs in Preview and Adobe Acrobat.
Any ideas? I find it odd that the problem exists over different apps, but not different filetypes. If I get desperate I will wipe and reinstall the system, but I'm hoping someone has a more refined fix before I have to resort to that.
