I can't open PDF files in IBook on my IMac. My PDF files are defaulting to IBooks when I try to open them but IBooks won't open them. I need to open Preview to open the file. A lot of wasted time. Any ideas?
Jack,
That means something is going on with your installation. Do you use any antivirus or cleaning apps on your iMac? if not then please restart the computer in Safe Mode per the directions in Use safe mode to isolate issues with your Mac - Apple Support and then try to do as you were instructed again.
Select a PDF. Press "Command + I". Change "Open With" to Preview. Then press the change all button.
We've done that repeatedly. It works for a while, then the default flips back to iBooks. (Or sometimes to Kindle.) And for some reason it only happens on my wife's MacBook Pro, and not on mine.
