Solution 1: Relaunch the iMovie Application
If the iMovie app has not been loaded properly on your Mac, then it can cause the iMovie not showing the video issue. The easiest way to fix the iMovie not playing video issue is by closing the app and relaunching it.
To do this, once the app is launched, you can go to the Finder and click on the “Force Quit” button. Alternatively, you can also press the Option + Command + Esc key combination to get the Force Quit window. From here, just select the iMovie app and force quit it to stop it from running in the background.
Afterward, you can launch it again and check if the iMovie app is still not working on Mac or not.
Solution 2: Restart your Mac
Apart from the iMovie app, chances are that there could be an issue with your Mac as well. In this case, you can just restart the system to fix the iMovie not working on Mac issue. All you got to do is go to the desktop and click on the Apple icon from the top-left corner. You can now click on the “Restart” button, confirm your choice, and wait for your Mac to be restarted.
Solution 3: Update iMovie or your macOS version
If you are running an old or outdated version of iMovie on your Mac, then you can encounter some of these issues. The easiest way to fix this is by going to the App Store and updating the iMovie app.
Similarly, you can also update the firmware on your Mac to fix all kinds of issues on iMovie. Just go to its System Preferences > Software Update to check the available version of the newest macOS. From here, you can click on the “Upgrade Now” button to update macOS and fix the iMovie not playing video issue.
Solution 4: Work on a New Project with Compatible Files
If the iMovie export has failed, then chances are that you have included incompatible files in the app or would like to export it in any other unsupported scheme. To check this, you can just save changes on your existing project and open a new one from its File menu.
You can also go to its File > Import Media button to load videos to your project. Just make sure that the videos you are loading on iMovie this time are 100% compatible with the application.
Solution 5: Reinstall the iMovie application on Mac
At times, even updating the app might not fix the iMovie not showing video issue. One of the easiest ways to fix this is by reinstalling the iMovie app on your Mac.
To fix the iMovie not working on Mac, you can just go to Finder > Applications and locate the iMovie app. Now, right-click the app icon and choose to move it to the Trash to uninstall it.
Once the iMovie app has been uninstalled, you can go to the App Store and install it again. Beforehand, try to get rid of all the iMovie data from the Mac to make sure you get a clean installation.
Solution 6: Reset PRAM or NVRAM on your Mac
NVRAM (stands for Non-volatile Random Access Memory) is responsible for holding vital information about the system, related to its overall processing. Though, you can easily reset the NVRAM (or PRAM) on your Mac that might fix the iMovie project won’t play in the viewer error.
To reset NVRAM on your Mac, you need to first turn the system down and wait for at least 15 seconds. Now, press the Power key to restart your Mac. As your Mac would restart, press and hold the P + R + Option + Command keys at the same time. Make sure that you hold the key combination for at least 20 seconds and wait as it would reset the NVRAM on your Mac.
Solution 7: Reset the iMovie App
If you think the iMovie app is not working on Mac due to a corrupt resource or preference, then you can simply reset it. To do this, close the iMovie app from running on your Mac. Now, launch the iMovie app again on Mac while holding the Option + Command keys at the same time.
This will launch the following pop-up, asking you to delete the existing preferences in iMovie. Just accept the prompt and wait as it would reset iMovie and launches it on your Mac.
Solution 8: Get Rid of iMovie App and Library Data
Lastly, if you are getting the iMovie not enough disk space error, then you can try to manually remove some of its data. For instance, you can just launch Finder and browse to the ~/Movies/ folder on your Mac. From here, you can browse the iMovie folder and manually delete the Render Files, Library Files, or any other kind of unwanted data.
This will make more available space on your system, fixing the iMovie not enough disk space issue.
