I have a 15 inch MacBook Pro 2016 with the 2.7GHz, and 460 graphics. I love the computer, but the main problem I have with it is it does not wake properly from sleep. If I use it within a few hours, it wakes up just fine, however, if I leave it with the lid closed for more than 4 hours then when I open the lid back up, it either completely reboots or I get the graphics glitch. Should I return, or is this more software related? I turned off FileVault, reset SMC, and NVRAM. Are there any other troubleshooting steps I should take?
