I recently bought a 2012 macbook air 128gb version. When I first started i checked the storage it had 120gb available in total storage. I downloaded ilife, iwork, itunes stuff, etc. Now when I am checking the storage I only have 60gb available? My suspicion is that it has something o do with itunes. have several movies on my itunes account and about 30gb being used is from movies. I haven't actually downloaded any movies though. I usually just stream them. Music also taking up 800 megabytes even though i only actually downloaded one song. And finally about 22 gb is being taken by "other" which i really don't know. I am a former pc user and this stuff was usually easy to figure out for me. Anyone know what the problem is?
