Question: How to free up space on My MacBook Pro
I have a Mac Book Pro 2013 I think 500GB. OS X Yosemite 10.10.5 . I have asked this before and still haven't been able to free up space. Right now it says 25GB free. I have tried deleting or backing up on an external pictures and videos. I have lot of pictures on my Photos folder. But when I open to check It shows Movies 40.29GB, Photos 28.52, Apps 22.7GB, Audio 10.3GB . That is 101.81 GB . Then my problem has always been "Other" 372.45GB !!! Somebody explained me once what was the Other file but I can't still get it. I don't know how I have 40.29GB in Movies (Im thinking the shows and music videos on my iTunes). But how the "Other" grows to 372 GB ??? How can I get some space? I tried backing up my computer with an external hard drive but didn't let me because It says I need some free space to do it?? -I use My Passport for Mac 1TB-
Any help would be appreciate.
MacBook Pro, Mac OS X (10.7)
