I think there is a misunderstanding. I have the black screen with only backlight issue when the system wakes up from sleep. If I don't let it sleep, I'm not effected by the issue. When I saw the thread, I thought maybe changing that value fixes my issue too, since I have the same graphics and wanted to quickly test it with clover boot options/gui on boot.
The problem is, when I changed it I couldn't even see the login screen. Since I'm still a newbie, I don't know even know how to do the change properly. For instance, should I change it like
*-platform-id:16260004_
or
*-platform-id:16260004
or
*-platform-id:0x16260004
So, I tried all of them and everytime I got blank/black screen with backlight on after apple logo. Which one is the correct way to do it btw?
I don't have a separate monitor with hdmi support nor I know how to remote desktop from PC to MAC that has login with password. (I did checked it via google, it seems there is a 3rd party app to do it but you cannot do it without physically loging on to Mac.)
Anyways, this can wait for now. Thanks for the replies though.
