To be very clear I purchased an Open box 2016. I understand that this maybe an edge case but I the fact that you can spend so much money on something and in turn get this is completely unacceptable to me.
- The biggest problem is a complete graphical meltdown. As soon as the dGPU kicks on I get flickering, tearing, artifacts, color bands, solid blue and red screens. It's worse when plugged into an external display. Apple claims it was an OS problem and released an update (that didn't fix this one). As someone who owned a 2011 faulty gpu MacBook I'm extremely hesitant to invest in one that is showing worse graphical issues than my old MBP.
- Login/Keychain problems: Once a day when I wake it from sleep it will refuse to accept my password. Just realized that not once has this machine asked for touchID, and yes I have it all setup. It somehow deleted my 7+ years worth of keychain passwords. Anytime I use an app or visit a page that requires credentials I get 3 pop-ups requesting a password that could be 1 of 3: my iCloud password, my new login password that it made me create, or my old login pw. Imagine having to do this with every single pw you use email, safari, etc.
- Probably related to above but my iCloud messaging and syncing doesn't work. Can't send messages, can't use handoff, make calls, nothing.
- Random mouse clicks, keyboard input will randomly not work. Literally could be one field in safari, a dropdown in a website nav, or trying to grab an object in photoshop.
- Constant beach balling and horrible performance compared to the 2011 mbp it replaced. I'm not exaggerating here.
- Disconnecting and reconnecting to the thunderbolt display is a nightmare. Usually involves opening and closing the lid or even restarting.
- I'm sure there are more bugs I'm forgetting.
Can I trade it in for another and be fine? probably. But I simply can't trust the 2016 models after this experience. And my hunch is they are going to be even worse in a couple of years when you get aging problems like a bad battery, gpu, ram, ssd. I can't even imagine what it'll cost to get those repaired in the 2016 design.
I know the 2012-2015's had their fair share of bad lemons. My 2011 mbp finally bit the dust last week and after 6 years I'm ok with that. I used a late 2013 rMBP that I ran hard every day for 3 years at my last job. I simply can't recall any major bugs or problems that I had with either.
It wasn't an easy decision because I do love the direction apple is going with the machine. My buddy brought over his 2015 yesterday and just looking at such a familiar stable machine helped me choose the completely safe route for now.
