Also does VirtualSMC.kexts show correct info about CPU , Fans , Battery ... etc with iStat menu ? Thanks Fan speed noise? My fans rarely even ramp up to hear them. No, VirtualSMC cannot show Fans reading but everything else (read the guide properly). No, I do no use iStat, so I cannot really tell. Link to comment Share on other sites More sharing options...

In windows everything is normal I've tried both OC and Clover . But I'm using Clover and FakeSMC.kext they works good with iStat menu That's unusual, can you check that your CPU isnt being hammered by some process?

Also tried CPUFriendFriend SSDT with all Profiles Nothing help Any way it is not a big problem. I am living with it for 2 years now Thanks I hope you fix it. This doesnt seem normal, I helped 2 people with P50s (both i7s) and never reported such problem. Make sure it's not something physical. Link to comment Share on other sites More sharing options...

My model is Xeon P530 4K workstation with Nvme SSD And Fans 99% of time is silent or works as usual. But when I start an App like Photoshop , fan start with noise like Jet and then work normal Don't know why That's totally not ok, since I use PS and Autocad and Archicad all open at the same time and I never had this issue .

Nullcpu No proper cleaning of the config Using EC ssdt when not needed. That's not how OC works. Link to comment Share on other sites More sharing options...
Rocdrew Posted April 13, 2020 Share Posted April 13, 2020 Have followed the guide as best as i could. And when i run it into that sanity check website, it seems fine. Can you help on what am missing for it to boot.. Link to comment Share on other sites More sharing options...
midi-sama Posted April 13, 2020 Author Share Posted April 13, 2020 24 minutes ago, IDON-NO said: can you share your config.plist please ? something is not clear or incomplete in your tutorial in GitHub just share it for comparison thx Also do you use DSDT or NO ? My guide on github is to follow the main *OpenCore Laptop Guide*, that one has everything, but then I added things that will need to be changed for our particular models. My guide does not (and will not) provide any config.plist/kexts because 1) you should make your own config, 2) kexts are updated every day, so no. If you properly read my guide I'm not patching my DSDT statically, im patching it dynamically with OpenCore ACPI binpatch (read the documentation at the end of the guide, there are tons of links). 9 minutes ago, Rocdrew said: Have followed the guide as best as i could. And when i run it into that sanity check website, it seems fine. Can you help on what am missing for it to boot.. Your config is a mess and the laptop guide didnt call for any of those. The sanity check is really not a good indicator (it just shows if things exist the way the guide says, but not how they should be for your exact situation). You're using uneeded kexts, you're using uneeded SSDT (the EC one, and I clearly stated in the guide not to use it), your ig-platform is wrongly put and so on... I dont expect it to boot. Please redo your setup again following the laptop guide with the modifications that my guide ask for. Link to comment Share on other sites More sharing options...
midi-sama Posted April 13, 2020 Author Share Posted April 13, 2020 Just now, IDON-NO said: @midi-sama I knew you won't share your config.plist But I don't understand one thing ; are you using DSDT ? Or only SSDT ? I have same model as you exactly. When following your steps I have KP 1) your computer has its own dsdt, I dont like patching the dsdt statically because of bios/uefi updates, im doing it dynamically with binpatch + ssdts. 2) that's a vague answer, show the kernel panic log.

DKayB Posted September 18, 2020 Share Posted September 18, 2020 Great guide thanks for taking the time to make. Huge learning curve for me but making progress. Most things working but Tap/Click on trackpad has never worked, two and three fingers is fine Trackpad not in System preferences. Can you point me in the right direction? I have not yet mapped the USB ports, might that be related???? Audio not working either, Bluetooth working Any help would be great Config.plist Link to comment Share on other sites More sharing options...

Make sure your battery patch is working, then the trackpad in system preferences will work, make sure you're using VoodooRMI not VoodooPS2Trackpad (disable VoodooPS2Mouse and VoodooPS2Trackpad from the configuration), also remember that the next release of VoodooPS2 will introduce brightness control natively, so no more SSDT-KDB required (i dont remember how it's named). Good Luck! Link to comment Share on other sites More sharing options...
DKayB Posted September 18, 2020 Share Posted September 18, 2020 Thanks for the fast reply! Not got the battery patch working yet so I will give it a try and let you know.

Spent a few hours trying to patch battery, basically copied your patches into my config.plist under ACPI, set all to true. No difference Read some guides but they are way over my head Any suggestions please. It's working so well otherwise, which makes it sooooo frustrating Edited September 19, 2020 by DKayB Link to comment Share on other sites More sharing options...
DKayB Posted September 24, 2020 Share Posted September 24, 2020 (edited) Tried to patch battery without success, this is what I did, can you tell me where Im going wrong??? Added SMCBatteryManager.kext Removed any reference to VoodooPS2Mouse and VoodooPS2Trackpad in config I could find. Copied the compiled .amls from your repo to my OC/ACPI folder, did 'snapshot' in ProperTree to reflect changes, saved, reboot. Still no battery meter. Opened your oc-additions.plist and copied SSDT-BAXX patch section to my config.plist under ACPI/patch (no sure if the order of patches mattered or if there are other changes needed) set all to 'true' (later tried changing to some to 'false') saved, reboot. No change Opened my the DSDT of my machine in MaciASL (dont really understand why I need mine???) also opened SSDT-BAXX inMaciASL In SSDT-BAXX changed _WAK,1,N to XXAK (I only changed _WAK, did nothing to 1 or N) same with the others, saved, (should I have pressed 'patch' in MaciASL?) replaced in OC, Snapshot in ProperTree. Also when lid is closed and light has started blinking all is OK but sometimes the fan starts, other times not. I'm obviously missing something UPDATE Finally got everything working! Thanks again for taking the time to make the guide. Took me a while and leaned a lot along the way but worth it in the end. Config.plist still a little bit of a mess, but doing the job. Added itlwm kext WiFi which seems to work with Heliport, speeds not great but fine for basic stuff.
