Administrators Hervé Posted July 13, 2017 Administrators Share Posted July 13, 2017 Really sorry but I've not had my hands on any Skylake platform yet, so no experience whatsoever. Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted July 13, 2017 Administrators Share Posted July 13, 2017 I don't recall if you can drop tables in enoch but you can in clover. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted July 13, 2017 Administrators Share Posted July 13, 2017 You can only drop SSDT with Chameleon/Enoch but I must admit I've never seen that MATS table being dropped in Clover before. I've only seen DMAR + SSDT CpuPm + SSDT CPU0Ist. Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted July 14, 2017 Administrators Share Posted July 14, 2017 you have to manually add the table into config.plist I have not seen MATS as a dropdown option in the configurator apps. but it might not only be the MATS table that has the hangup as some machines do not have MATS table. it is an issue with some of the SSDT table headers. you can see what tables your machine has using clover F4 dump and look at what tables it has in the ORIG ACPI folder then manually add tables to clover config till you find the one that causes the lockup. in my case I did not have a MATS table.

haydara Posted July 14, 2017 Author Share Posted July 14, 2017 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 Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted July 15, 2017 Moderators Share Posted July 15, 2017 Not a solution but just information that might be the cause https://alextjam.es/debugging-appleacpiplatform/ Link to comment Share on other sites More sharing options...
haydara Posted July 16, 2017 Author Share Posted July 16, 2017 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.
