So you still need a professional YouTube downloader for Mavericks which helps to batch download 1080P/720P/4K YouTube video in MP4 or WebM as well as convert YouTube to MP3, MP4, MOV, MKV, ProRes, AVI, WMV, etc. And downloading always fails with ClipGrab and MacTube. However, still there are some people who wouldn’t like to use a safari extension for fear that it slows Safari or whatever reasons. You can download YouTube videos using a safari extension in Mavericks like YouTube5 or using the free desktop app ClipGrab or MacTubes. Though there is no activity windows with Safari in Mavericks and thus people can no longer download YouTube videos using the activity windows feature, there are several other options for downloading YouTube videos in OS X 10.9 Mavericks.

Downloading video from YouTube on Mac is no longer a tough task whether you are with Mountain Lion (OS X 10.8), Lion(OS X 10.7), Snow Leopard(OS X 10.6) or even with the latest Mac OS system Mavericks(OS X 10.9).
