jwresp Posted November 11, 2017 Share Posted November 11, 2017 Hello guys, I am very happy about my E7440 running High Sierra, however I experience an issue while connected to two external monitors. I connect using the HDMI port and a Mini DisplayPort to DisplayPort adapter. This works great, but when the screen is locked, or when the system goes to sleep, the system crashes and shuts down. Without any external monitors connected this problem does not occur. I am using the bootpack from the Clover guide along with Lilu.kext, Shiki.kext and IntelGraphicsFixup.kext. After reading this topic, I was thinking that this might have something to do with my current SMBIOS ProductName (MacBookAir6,2) or with the current VRAM amount (1536MB). I tried looking up the error in system.log, without any luck. Is this a known problem, and would changing the VRAM or ProductName solve this problem? Thanks!

Administrators Hervé Posted November 11, 2017 Administrators Share Posted November 11, 2017 Try MacBookPro11,1 SMBIOS instead of MBA6,2. VRAM is not an issue, never has been on Haswell iGPUs. Link to comment Share on other sites More sharing options...
jwresp Posted November 13, 2017 Author Share Posted November 13, 2017 Thanks Hervé! Changing the SMBIOS ProductName to MacBookPro11,1 did the trick. It now works perfectly! Link to comment Share on other sites More sharing options...
