iMovie 9 Not Working for Mojave? Problem Fixed

In iMovie's history, iMovie 9 is an important version you can't get it passed. iMovie 9 was also called iMovie '11 which is part of Apple's iLife suite. iMovie '11 was released with features such as trailer making, enhanced audio editing, real-time filter effects, character finder, sports and news themes, and more. It's a powerful video editing without loss of simplicity.

After Apple released iMovie 10, so many people was disappointed with it and want to get back iMovie 9 on Mojave. It's a good idea on Sierra (macOS 10.12) or even High Sierra (macOS 10.13).

However, getting back iMovie 9.0.9 on Mojave won't solve the problem. Due to the hardware and system issue, you at most retrieve an unworkable iMovie 9.

So if you update to Mojave and find out that iMovie 9 not working or iMovie 9 not responding, the following 3 solutions are available, excluding get back to iMovie 9. Personally, I'll either update iMovie 9 to iMovie 10 or choose an iMovie for Mac alternatives directly. For the third solution, it's a little bit complicated. Do make backups before you start downgrading.
