iLife 11
I have an old CD with iLife, and I should like to have iMovie theme to use on my Mac with Catalena/BigSur. I that possible or is the version too old?
iLife is a discontinued software suite, so cannot be updated. Only iMovie and Garageband remain of the original apps in the suite, and those are sold separately.
You would need to upgrade to Catalina or Big Sur in order to upgrade to current iMovie. I'm not running either of those operating systems so not sure whether the current iMovie provides more themes.
