Hey! I just got a new MBP and have been comparing it to my iMac 5k. Something I've noticed is "System" takes about 35Gb on my MBP but takes up over 70Gb on my iMac. I get the feeling that something is amiss with my iMac, but can't figure out where all that data is stored or what it is. I've check the size of numerous folders and it's not adding up. All the threads I've found deal with "other" not "system". Thoughts?
