I'm needing to access my macbook pro (work computer) from home via chrome remote desktop. I'll need to make sure the MBP doesn't go to sleep so I can do this. Any ideas on a safe way to do this?? Unchecking "Put hard disk to sleep when possible"? I'm running Yosemite 10.10.2 on a 15 inch retina, mid 2014. Many thanks!
