My recommendation to everyone running a Mac is to go to Walmart or any other discount store and pick up a cheap laptop for $200 or less and be done with it.
$200 wasted (maybe). If you already have a mac, you can partition the hard drive using Bootcamp (default program) and install free Ubuntu Linux or Debian on the second partition. You could even install Win 7 or 10 on it to your heart desire, but I suggest Linux or Debian for sticks-it makes running them super easy (typically). You may do the same on PC (make a second partition and install Ubuntu). Seeing all those complains about Win and sticks, I don't know why you guys cling to Win so much.
I use Windows 7 and 10 in my work, and it is fine, but totally unnecessary in running sticks and/or any mining besides, maybe Vega.
