Is Preview malfunctioning on your Mac? Let's troubleshoot! First, try the simple fixes: force-quitting and restarting the app, then trying other files to rule out file corruption. A quick system restart is also worth a shot. If these don't work, more in-depth solutions are available.
You're trying to view images, but your trusty Preview app refuses to cooperate. Is it the files, or is Preview itself the culprit? This guide provides solutions to get Preview back on track.
Why Isn't Preview Opening?
Several factors can prevent Preview from launching. A corrupted file (PDF, JPG, PNG, etc.) is a common cause. Test this by opening different files. If they work, the problem lies with the original file.
Other potential causes include:
- Preview App Issues: A misconfigured preferences (PLIST) file can cause problems.
- macOS Bugs: System updates sometimes introduce glitches affecting app functionality.
- Hardware Malfunction: While less frequent, hardware issues can be the root cause. (MacKeeper's Premium Services might assist here).
Fixing Preview on Your Mac
Here's a step-by-step guide to resolving Preview issues:
- Force Quit Preview: Use the keyboard shortcut Command Option Esc, select Preview, and click "Force Quit."
-
Test with Other Files: Attempt to open different files. If they don't open, the issue is likely not file-specific.
-
Restart Your Mac: A simple restart often resolves temporary glitches. Hold down the Power button until the Mac shuts down completely, then restart.
-
Reset Preview: Resetting Preview's preferences can fix configuration problems.
- Open Finder.
- Go to Go > Library (hold down the Option key to reveal it) > Preferences.
- Locate and delete
com.apple.Preview.plist. - Restart Preview; a new PLIST file will be created.
-
Update Your System: Outdated macOS can cause compatibility problems.
- Go to Apple menu > About This Mac.
- Click Software Update and install any available updates.
- Restart in Safe Mode: Booting in Safe Mode disables non-essential startup items, helping identify software conflicts. Instructions vary slightly depending on whether you have an Intel or Apple Silicon Mac (see original instructions for detailed steps).
- Reinstall macOS: This is a last resort, but reinstalling the operating system can resolve deep-seated system issues. Boot into Recovery Mode (Command R during startup), select "Reinstall macOS," and follow the on-screen instructions.
Solving Preview Problems Effectively
Even top-tier Macs can experience occasional hiccups. Start with the simpler solutions and progress to more involved steps if needed. If you're still facing issues, consider seeking assistance from MacKeeper's tech experts via their Premium Services.
