Yesterday I started experiencing display hiccups in my new Macbook Pro
The issue is most noticeable when playing videos, though it really effects every animation: minimizing windows, switching screens, even typing is now choppy. The display has hiccups where it freezes for a split second, making it very choppy. I get lots of warning from WindowServer in my console (snippet here). I've tried several solutions so far:
- Rebooting
- Disabling automatic brightness
- Resetting my user keychain
- Disabling iCloud keychain
- Removing all user LaunchAgents
- Turning WiFi off and on again
but none of them have worked. I'd really like to avoid a full OS reinstallation and from what I can see, I'm not the only one experiencing this issue. It appears to be related to the 10.12.1 update.

Troubleshooting is basically a process of elimination and often requires patience. Below I have some steps for you to try and report back on.
1. Safe Mode
What happens when you run your computer in Safe Mode? To do this:
Once you've done the above, report back on how your computer was in Safe Mode and how it was again when not in Safe Mode.
2. Reset your NVRAM
Older Macs had what's called Parameter RAM (PRAM), newer Macs use Non-Volatile Random-Access Memory (NVRAM). It may be worth you also resetting this. Here’s how to:
Note: When you log back in you may need to readjust some of your system preferences (e.g. mouse speed, time and date/timezone, etc).
3. Reset the SMC
Your computer's System Management Controller (SMC) can also be reset. The instructions for doing this on your particular MacBook are:
After resetting both your NVRAM and SMC, use your computer and report back on how it's now going.
