Hello Jake , how are you I hope you are ok I'm having a problem with the power management on my Dell HD 520 , the wake after sleep does not work , so when I click on sleep or close the lid ,The Screen become black and gradually become white and never wake up after sleep ,I tried many solutions but no success I am using clover , what can be the reason for this and the solution to this issue on skylake because it was working properly on sierra and it is not working in high sierra. Thanks for any reply

Thank u Jake for the info provided and thanks to all who might be able to find a solution to the ACPIPlatform kext in HS for Skylake HD520. Trying my best to find the solution but no luck. so i think we need to ask Ermac for his Enoch project about dropping the BGRT table in his releases because it can only drop the DMAR and many other which i tried to drop all one by one and in several sets but no luck. Found in clover that only dropping the BGRT and DMAR can make the installer and Os partition to boot smoothly. Hope someone can tell Ermac asap to test. Also If u think there can be a solution by a tinny ssdt or dsdt edits to drop any tables as in enoch and clover .. that can be a smart solution. I can confirm that it is BGRT Table to be dropped because there is no table named MATS in the clover origin folder. Thanks for all support.

Thanks for all .. i tried to see what table to be dropped to boot the high sierra in clover , found that dropping only two tables , DMAR and GBRT tables.. can boot the High sierra in clover , which means it is not related to the MATS table. so i can say it is sorted in clover but still stuck with enoch , how we can fix that for enoch ?? Waiting any reply .. Thanks

Herve , How r u Seems the problem is how to drop the MATS Table using enoch Appleacpiplatform kext not loading ,, as Piker Alpha said I tried to patch the kext but not successful can droping tables be done via ssdt - dsdt edits .. i need ur help plz Thanks

Sorry Herve .. Got nothing ?? is there any dsdt , ssdt to add to sort the AppleACPIPlatform kext error in enoch, probably it is causing the mats error??

Thanks Herve .. i sent the clover config plist file just to check it but sorry i didnt refer to the drop tables in it that sorted the clover booting , will there be any solution with enoch ???

Herve , Drop tables has sorted my problem in clover , how can enoch drop tables ,, the error is related to the mats table , take a look at my clover config plist Thanks
