iMovie for Mac has been revved to version 10.1.1. It’s available via the Updates tab in the Mac App Store. According to Apple, the upgrade:
° Resolves an issue with YouTube sharing that could prevent sign-ins for users with multiple accounts;
° Fixes a problem that could prevent white balance adjustments from being applied to clips;
° Correctly plays Sony XAVC S clips captured at 100 or 120 frames per second;
° Resolves an issue that could lead to the incorrect display of images.
Clips are now copied when dragged from the Project Media container to events in the Library list. iMovie 10.1.1 also sees stability improvements.
