How to get an iMovie compatible with Catalina?

Use this procedure to obtain the highest version of iMovie that Catalina will run:

To update/redownload iMovie 10, drag your iMovie 10 app from the Applications folder into the trash, but do not empty the

trash. Sign in to the app store and open your purchases folder by clicking on your name at the bottom of the app store side bar. You will see your purchases displayed, including iMovie 10. Redownload/update iMovie from there. If not successful, drag your present iMovie app out of the trash and return it to the Applications folder.

If iMovie came with your Mac, then that's a "purchase". It may be in your app store Purchases but is just hidden. In your app store purchases folder there is an item at the top of the pane called "View Information". Click on that and a window will pop up where you can choose to unhide hidden items. Do the unhide procedure and see if your iMovie 10 now is displayed in your purchases. You might need to close out of the app store and re-log in. If it were on your Mac at one time, it should appear. If it does appear, follow the redownload instructions that I posted above in a previous response.

I am in the same predicament. I followed the procedure you described. But, in the app store, all that pops up is iMovie compatible with 11.5.1. I cannot upgrade to that OS.

What now if your previous procedure does not work?

SkiBumMexi,

Other than the procedures in my earlier responses in this thread I am not aware of any other way of obtaining an earlier compatible version of iMovie 10.

However, you should post your question in a new thread, and include details like what iMovie 10 version you are trying to update, what OS you are presently running, what happened when you tried the update procedure described earlier in this thread, were you able to see iMovie 10 in your purchases, and so on.

You are welcome. Glad you were able to get the download.

This was not successful for me
