In case you put your video files to iMovie for video editing or something, and unfortunately iMovie is unresponsive from time to time, then you should first have a check on your imported file format. Make sure if the file format is compatible with iMovie since the iMovie supported video audio formats are limited within MP4, MOV, MPEG-2, AVCHD, DV&HDV. Therefore, when your iMovie doesn’t respond the command you give, the culprit may go to your unfriendly file formats.

Reason and Solution No.2 - iMovie Version & Mac OS

When iMovie is not responding, we should also take iMovie and operating system compatibility into account. As is known to all, each version of iMovie has its own range of application. The previous iMovie versions can only function on Mac OS X 10.3-10.5. And currently the most widely used iMovie 11 works fine on Mac OS X 10.6-10.9. And if your operating system is updated to the latest Mac OS X 10.10, all you require to make efforts is to update your iMovie 11 to the upgraded iMovie 10.0 or 10.0.6. >>>iMovie VS Final Pro Cut , Which One is Better?

Chances are also that the internal parts of your computer precisely CPU accumulate s dirt and that can cause slowness. Besides, when you are launching iMovie for working, make certain if you are running other tasks online or via other software since this might lead to sluggishness to your iMovie, as well. Confronted with such condition, you are required to clean your computer regularly and shut down the unnecessary tasks lest it contributes a lot to not responding from iMovie problem.

So it’s advisable for you to clear such baggage after every task has been accomplished which also ensures the iMovie memory remains high.

Ever considered the reason of iMovie unresponsive goes to the improper conduct of iMovie and the potential virus? It’s highly possible. Assuming there were some mistakes committed in the process, iMovie would fall into the no responding quagmire or iMovie keeps crashing sometimes. Also the unknown virus esp. the worm virus is the major contributor to iMovie won’t respond problem.

Go to a reputable site online and download the suitable iMovie program and install into your computer. And later re-launch your computer and iMovie to check if it’s back to normal. (Still have problem, seek the assistance from a manufacturer who understands it well than you do.)
