Can anyone give me some tips to free up some space on my 2013 MacBook Pro? I have 21GB available of 250 GB. My last iPad Pro back up could not be done. What I was thinking of doing is moving my iTunes to an external hard drive. This would free up enough space but is it safe to do so? Are there any "quick fixes" to free up more storage? Also, if an external hard drive is the answer, which one do you recommend? I do have a 2TB Time Machine. Can I not just move my iTunes there? Or is iTunes Match something that might work? Sorry for my ignorance but can someone please advise? Thanks.
