This article explains how you can fix if iMovie is not working as expected on your Mac. iMovie is Apple’s video editing software that is available on the iPhone, iPad, and Mac.
Although iMovie is a great application, sometimes you may run into issues using it. Some of the common problems are listed below:
- iMovie won’t open, respond.
- The software unexpectedly quits.
- The software does not save, export or upload.
- The software is extremely slow.
Most iMovie problems can be fixed by doing one of the following tips:
Please make sure to check after each step to see if iMovie starts working.
1. Restart your Mac. It is simple but it works. You can restart your Mac by clicking the Apple menu and then Restart.
2. Update your Mac. Make sure that you are running the latest version. Here is how you can check for updates and update:
- On your Mac, click the Apple menu, System Preferences, and Software Update. If there is an update available, follow the onscreen instructions. If you are running an earlier version of the macOS software (macOS High Sierra and earlier), go to the App Store and click Updates.

- You may want to reset your network settings on your Mac.
If you have another device, can the other device connect to the Internet? If the other device also cannot connect, you may try the following tips:
- Restart your Wi-Fi router. Unplug the power cable. Wait 1 minute. Then plug the cable back in.
- Make sure that your Mac is not too far away from the router.
- Try a different connection if possible.
- There may be issues with your Internet provider. You may want to contact them for more help.
5. Reset NVRAM or PRAM. This is also very easy to do. Here is how:
