I've been working with some of the software engineers over at applecare to try and resolve this weird bug(?), and I was wondering if any kind souls with Retina Macbook Pros would be willing to test something. (Shouldn't take more than 5-10 minutes)
The issue is, if the macbook pro screen resolution is set to the highest setting ("More space, looks like 1920x1080"), then is allowed to hibernate (not sleep), plugging in a power adapter will cause the screen to turn on.
Here are the steps to test this:
1. Close all open programs.
2. Go to "System Preferences" > "Displays"
3. Set the "Resolution" option to "Scaled", and select the furthest right of the 5 options, titled "More Space".
4. Close "System Preferences"
5. Open a terminal window, and type:
(When you close the lid of a running mac, it will go into "sleep" mode. If the power adapter is unplugged, the mac will power the memory until a certain amount of time has passed, after which it will save all the contents of the memory to the hard drive, and go into "hibernate".
The default time to wait is 4200 seconds, which is 70 minutes, but for the sake of time, the command in step 4 will reduce that wait time to 30 seconds. You will be asked to enter your password.)
6. Unplug the power adapter, if connected, and close the lid of your macbook pro.
7. Wait 2 minutes, to make sure the macbook pro is fully in hibernate mode.
8. Without opening the macbook pro lid, connect the power adapter.
9. Watch and see if the white apple on your macbook pro's lid lights up (may take up to 10 seconds).
To change everything back to the way it was, all you have to do is enter this command in the terminal window:
The issue only seems to happen on the highest resolution setting, but please let me know if it happens on other settings as well.
Please also post what version of OSX you are running!
Thank you all in advance for your help!
