If Logic Pro X isn't performing as expected, try these basic steps to attempt to fix the issue. 

These steps might not cover your specific issue and are not comprehensive.


1. Ensure Logic Pro X is up to date

Installing the latest update ensures that your software has the latest improvements and enhancements. Choose Apple () menu > Software Update and make sure that you have the most recent update for Logic Pro X.

Learn how to update Logic Pro X on your Mac.

2. Verify that your computer meets the system requirements for Logic Pro X

See Logic Pro X Technical Specifications.

3. Review Logic Pro X documentation

To verify that Logic Pro X is working correctly, it's always a good idea to review the documentation to ensure that you clearly understand the expected behavior of what you're trying to do in Logic Pro X. Following this step thoroughly could save a lot of time by eliminating perceived issues.

The user guides are available from the Help menu in Logic Pro X, or as a PDF download. To access the user guides in Logic Pro X , choose Help and select the user guide you wish to view. Access the user guides online or download PDFs.

4. Check third-party compatibility

If you're using a third-party audio interface, MIDI interface, storage system, control surface, or plug-ins, check the support area on the manufacturer's website to be sure that you're using the latest version of the relevant driver or other software for your product. Learn more about resolving possible issues with Audio Unit plug-ins.

5. Test with no audio driver

You can isolate issues with audio devices by starting Logic Pro X with no audio driver. Press and hold the Control key immediately after Logic Pro X starts to open. A dialog asking whether you wish to launch the Core Audio Driver will appear. Click "Don't launch" and see if Logic Pro X starts up normally. If Logic Pro X launches with no audio driver, check with the audio device manufacture for an updated driver. There could also be an issue with an Audio Unit plug-in. Learn more about disabling or removing Audio Unit plug-ins to fix issues.

6. Test using the computer's built-in audio hardware

If you use external audio hardware, try setting Logic Pro X to use the built-in audio hardware on your computer. Choose Logic Pro X > Preferences > Audio from the main menu and click the Devices tab. Choose the built in audio hardware from the Input Device and Output Device pop-up menus. If the issue is resolved using built-in audio, refer to the manufacturer of your audio interface.

7. Start Logic with a different project template

Sometimes project files can become damaged, causing unexpected behavior in Logic. If you use a template, damage to the template can cause unexpected results with any project subsequently created from it. To create a completely fresh project choose File > New from Template and select Empty Project in the template selector window. Test to see if the issue is resolved in the new project.

Sometimes, issues with the data in a project can be repaired. Open an affected project and open the Project Information window with the Project Information key command. Click Reorganize Memory to attempt to repair the project. When you reorganize memory, the current project is checked for any signs of damage, structural problems, and unused blocks. If any unused blocks are found, you will be able to remove these, and repair the project. Project memory is also reorganized automatically after saving or opening a project.

8. Isolate an issue by using another user account

For more information, see how to test an issue in another user account on your Mac.

9. Reset the user preferences

You can resolve many issues by restoring Logic Pro X back to its original settings. This will not impact your media files, presets, or patches.

Important: Before resetting user preferences, be sure to first review your Logic Pro X preferences and note the settings you've chosen. Once you reset Logic Pro X preferences, your custom preferences will return to default settings. To learn more about different preferences, see Logic Pro preferences overview in the Logic Pro X user Guide. 

To reset your Logic Pro X user preference settings to their original state, choose Logic Pro > Preferences > Initialize All Except Key Commands. 

10. Delete user preferences

To delete the user preferences, do the following:

  1. Quit Logic Pro X if it is running. 
  2. In the Finder, choose "Go to Folder" from the Go menu.
  3. Type ~/Library/Preferences in the field and click Go.
  4. Remove the "" file from the Preferences folder. Note that if you've programmed any custom key commands, this will reset them to the defaults. You might want to export your custom key commands before performing this step. Learn how to Browse, import, and save key commands.
  5. If you upgraded from an earlier version of Logic Pro, also remove the "" file.
  6. Restart the computer.

After following these steps, try to reproduce the issue you were experiencing with the default preferences. If the issue is resolved, reset your preferences to the way were before and then test again.

11. Reinstall Logic Pro X

Another approach you might consider is reinstalling Logic Pro X. To do this effectively, you need to remove the application, then reinstall it. You don't have to remove everything that was installed with Logic Pro X. 

To reinstall Logic Pro X, do the following:

  1. In the Finder, choose Applications from the Go menu.
  2. Locate the Logic Pro X application and drag it to the trash.
  3. Open the Mac App Store.
  4. Click the Purchases button in the Mac App Store toolbar.
  5. Sign in to the Mac App Store using the Apple ID you first used to purchase Logic Pro X.
