viking1304 Posted November 28, 2021 Share Posted November 28, 2021 Since a lot of things have changed in last few years, I had to read a lot in order to catch up. Installation wasn't difficult, thanks to @Jake Lo. Almost everything works fine, but I have to ask a few questions. 1. What exactly is in SSDT-E7450.aml? I will decompile it for sure when I find some time, but quick info would be appreciated. 2. Do I need to change anything related to ACPI, since I am on latest (A24) BIOS? 3. What is the best way to disable NVidia GeForce 840M with OC? I guess DeviceProperties method. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted November 28, 2021 Administrators Share Posted November 28, 2021 1. What SSDT-7450.aml? Maybe a single table where the patches of all the usual OC SSDT tables (EC, CPU PM, USB, PNLF, etc) are unified. 2. Not when you use add-on SSDTs only rather than a patched DSDT 3. an add-on SSDT made to that effect. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted November 28, 2021 Moderators Share Posted November 28, 2021 Just add this additional SSDT-Disable-DGPU.aml to ACPI folder and Make sure to add it to the config.plist as well until ACPI/Add Link to comment Share on other sites More sharing options...
viking1304 Posted November 28, 2021 Author Share Posted November 28, 2021 @Hervé I was talking about SSDT-7450.aml from E7450 OC 0.7.5 that Jake posted. Most important thing is that installation went fine and that macOS works. I was just curious what he actually put inside. Since I wasn't here for a last few years I forgot some things. Thank you very much for reming me. Everything is clear now. @Jake Lo I already tried DP method and it works fine. I will also try this method soon. Thank you very much . Not just for this answer, but also for the OC package and config. The only real issue that I have is that trackpad is little hectic, but that is not related to your package or config. I will submit an issue report as soon as I figure out how to find ALPS HW version. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted November 28, 2021 Moderators Share Posted November 28, 2021 If you're using my OC 0.7.5 bootpack, then it includes skyrilHD's version of voodoops2controller that enables multi gestures for Alps version 7. You might just need to decrease the tracking speed. Link to comment Share on other sites More sharing options...
viking1304 Posted November 28, 2021 Author Share Posted November 28, 2021 I am aware that you replaced old VoodooPS2Controller-Alps.kext with that one and indeed it works much better. Unfortunately I noticed random zoom-ins of web pages while I am scrolling with two fingers, so I already submitted this ticket. Link to comment Share on other sites More sharing options...
