The only way to fix software bugs is to update your Mac to the latest available software. This might be happening as the result of a bug in macOS, which will still be present after you restart it. You might find that Preview still fails to open even after restarting your Mac. However, you’ll lose any unsaved progress in all your open apps when you do this. If your Mac doesn’t respond, you can force it to shut down by holding the power button. Then wait for the computer to power off and on again. Open the Apple menu and choose to Restart your Mac. The easiest way to fix most minor problems with macOS is to restart it, allowing the operating system to start up properly again. The principle here is essentially the same: Preview might be failing to open because your Mac operating system has started misbehaving. If restarting Preview didn’t work, try restarting your Mac instead. This should close down the app even if it had frozen.Īfter successfully closing Preview, try opening it again to see if it works now.

Then select Preview from the list of open apps on your Mac and choose to Force Quit it be warned, you’ll lose any unsaved progress when you do this. In that case, open the Apple menu and click Force Quit. However, this may not work if Preview isn’t responding. The safest way to close an app is to click Preview > Quit Preview in the menu bar. This allows Preview to uncross its wires and start afresh, hopefully working better on your Mac this time.

Most of the time, though, all we want to do is double-click a PDF and have a look at it. Using the Preview app is a treat, with plenty of groovy features under the hood should you care to go deep. Second punishment: by using Acrobat, you’re NOT using Apple’s built-in, elegant, powerful, joy-to-use Preview app. I wouldn’t make my dog use Acrobat Reader. Every version of Acrobat Reader is misery to use: slow to launch, clumsy to operate, thousands of indecipherable options in the Preferences dialog, and very “un-Mac-like.” First punishment: Adobe’s punishing your by making you use Acrobat Reader (or Acrobat Reader DC, or Acrobat Reader Pro DC, or maybe an older version of Acrobat Reader).

If Acrobat Reader has taken over your PDFs you’re being doubly punished.
