MacX YouTube Downloader for Mac is a free utility for downloading and locally saving videos from YouTube. YouTube has recently implemented changes to prevent downloading of its videos, but MacX YouTube Downloader for Mac seems to be able to bypass the current tricks (unlike some other similar apps). You can download MacX YouTube Downloader for Mac from the publisher's site or from several Mac download portals.
Installing MacX YouTube Downloader for Mac is easy, and the app functions well. There's configurability in the way it operates and the formats it handles, but the defaults will suffice for most users. Even HD videos can be downloaded, as can all standard YouTube formats. The publisher claims over 420 codecs are embedded in the app, but we didn't try all the possible variations after proving we can download the most common ones for playback on Apple devices (including iPhone and iPad). In addition, we could save in native formats for Android and Blackberry.
MacX YouTube Downloader for Mac worked on every clip we tried without an error, which is notable for apps of this type. There is no download manager included, but the clips seemed to download at full connection speed, so the lack of a manager (and simultaneous download streams) wasn't an issue for us. We liked using MacX YouTube Downloader for Mac for its simplicity and reliability.
