I just got my maxed out 15'' yesterday. Haven't had any time to put it through its paces yes, but no defects right off. My question is about the screen brightness. I know thees were suppose to be brighter I but I have it at nearly max to get to where my 2015 iMac is. My iMac is about 75%, and the MacBook is 3 clicks away from full brightness but is a little under the iMac. It's been a while since I've had a MacBook, is this normal on these?
