pafkata Posted December 13, 2016 Share Posted December 13, 2016 I do not know what is the issue with the issue mnx's installer. Follow up on the thread if Sierra is possible....Today I updated via App store to 10.12.2 - all good except for sound. I just used the old kext used during installation and rebuilt kernel cache and sound is working now. I do not see any other issues. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted December 14, 2016 Administrators Share Posted December 14, 2016 It's a well know fact that every update installs a vanilla AppleHDA which therefore requires re-patching. The alternative is indeed to replace the new vanilla kext by an earlier pre-patched Sierra version. Link to comment Share on other sites More sharing options...
mnx Posted December 29, 2016 Share Posted December 29, 2016 yes from those links At least booted. Solved. I used MBA 5,2 for SMBIOS and after that my Dell Latitude E6220 (without DVD) on i7-2640m booted successfully and installed with no issues. Maybe will be helpful to someone. UPD: Updated to Sierra from El_Captain. Works ok, only clicking sound disturbs me at that moment. Link to comment Share on other sites More sharing options...
mnx Posted January 13, 2017 Share Posted January 13, 2017 Have another issue. 1. If I try to create config.plist with any other MBP (8,1 or 8,2) system cannot boot - all guides told me this shall be the right choice. 2. Starting of script ssdtPRGen also told me that MBA shall not be SandyBridge. 3. Overheating a problem - system don't know fans speeds, controls unpredictably - sometime too hot and book stood still after. Cannot say this is 100% workable version. Advice where to dig and what to do please. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted January 13, 2017 Administrators Share Posted January 13, 2017 Please use the existing and proven guides that provide all that you need for this model. Link to comment Share on other sites More sharing options...
mnx Posted January 13, 2017 Share Posted January 13, 2017 Give me a link please. Guides for installation is ok, but not give the answers to create fully supported machine. As long as I need to generate DSDL and etc... it is lack of descriptions to configure machine right way. And as I told - in guides my PC shall be MPB 8,2 or 8,1 but it not loads so far with that.
