Hello there uhmm just wanna ask any thoughts in my little problem of my macboook pro installing MacX Youtube downloader, it was almost a year since used this app that no problem at all, but now this month im having a problem of downloading videos on youtube, is it because i have new OS the Mavericks or what? but take note when i upgraded my mountain lion to mavericks it was the day when mavericks is already available that week, so i thinks its more than 5months i guess since i update my OS but just this month i encounter error downloading videos using MacX Youtube downloader every time i download it will stop automatic so i need to click it again the button "download" keep on doing every very minutes, it sometimes at almost end of downloading it will stop the whole operation so back to the beginning again of downloading im piss off of this...hope you guys can give me any opinion or suggest better youtube downloader for free?
