e7270: black screen on wake

Hey, @beavermml, can you post the bootpack/clover folder you are using now?  I'm having a similar problem with a black screen on wake on an E5570 so I'm hoping to see what you have in your folder that got the sleep/wake working. 

 

I know you wrote about the platform you used but I tried that too and I'm not getting it to take effect so I'm missing something else that I'm hoping your final clover will help me figure out.

 

Thanks!!

Thanks for posting your EFI @beavermml.  But it's interesting that you don't have the ig-platform-id in the config.plist file.  At least not that I could find.  So I'm not seeing how you were changing the ig-platform-id in your loading.  But don't worry about answering that because my issue is now resolved.  

 

My problem was resolved as described in another topic.  My problem was having a laptop with a 2nd GPU that macOS does not support. The solution was to disable it.  So it's probably not your case and I don't know if a 7270 can have a second GPU, but in case it can, check your System Information (in Utilities folder) to see if you have more than one entry in "Display/Graphics".
