Since upgrading to Sierra 10.12.5, I've noticed that when waking from sleep, it would not detect my monitor. I tried a number of different things that didn't help.
Finally, I found out that if I power cycle the monitor while the system is sleeping, it detects the monitor correctly and wakes normally. Of course, this is not the most ideal solution, but it's the only thing that works right now...
I'll continue to try to dig for a more elegant solution.
Edit May 18, 2017:
The problem doesn't happen when I use HDMI to HDMI to connect my monitor. So, I'm assuming it's the monitor or the DisplayPort to DisplayPort that I had been using. I've ordered a replacement cable that should arrive in a few day.
Update June 1, 2017:
I'm back from vacation and finally narrowed down my problem to the darkwake setting in Clover Configurator. Previously, I had it set to "darkwake=1". Now, I have it set to "darkwake".
Also, during my trial and error testing, I stumbled upon something interesting. We already knew that by enabling the HD 530 graphics we were able to get iBooks to work. But, now, I know how to enable Quick Sync, however, doing so will break iBooks. So, you must make a choice on whether you want to have iBooks working or Quick Sync to help rendering times on certain apps.
I have only tested this with iMac17,1 system definition.
How to get iBooks working:
- Use MultiBeast to enable the Intel HD 530 graphics.
- Open your config.plist with Clover Configurator.
- In the ACPI section, click on List Of Patches and select "change GFX0 to IGPU".
- Double check the Graphics section and make sure that "0x19120000" is in the ig-platform-id.
- Save.
- Reboot and enable the HD 530 graphics in BIOS.
How to get Quick Sync working:
