Creating a default app.
I made ms word a default app for my documents as most are already word. By going through finder, apps, get info, there was an option under comments there was an option to "open with" with a further option to 'change all". So I made ms word a default. Then I try and do the same with pdf documents but the option isn't there. I check all the other apps and the same, this option has been deleted somehow. So I get on to support who can offer no assistance. They tried to see what happens in safe mode but the problem is still there.
So, does anyone else have any suggestions?
