offficial_florin Posted September 25, 2016 Author Share Posted September 25, 2016 Hello. I just finally upgraded my Dell Latitude E7450 to Sierra. The first time I stated I had no Wi-Fi no Ethernet, nothing. I restarted and then the system run in to a kernel panic, crashed and rebooted. How can I fix this or even downgrade back to 10.11.6?

Administrators Hervé Posted September 26, 2016 Administrators Share Posted September 26, 2016 @offficial_florin: no double posts please. And you can't downgrade OS X, you can only re-install from scratch. Link to comment Share on other sites More sharing options...
seeker_pl Posted September 29, 2016 Share Posted September 29, 2016 Hi,Managed to install macOS Sierra on e7450.I installed Clover rev 3763 and copy the Bootpack from:https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-precision-el-capitan-clover-guide/&do=findComment&comment=54632 But I left original Boot folder from Clover rev 3763, the one provided with bootpack was not working for me. E7450 restart when I clicked on Macintosh SSD after Clover shows up. I copied to library/extensions below kexts from EFI/Clover/Kexts/other/LE (check screenshot) ACPIPoller.kextAppleHDA_ALC293.kextBrcmFirmareRepo.kextBrcmPatchRAM2.kextDisableTurboBoostBattery.kextEAODFix.kextFakePCIID.kextFakePCIID_Broadcom_WiFi.kext I Repaired permission and rebuild cache.

(screenshot) There are some graphic issues (check screenshot). setup_var 0x15b and setup_var 0x15c were set to 0x3 Touchpad stop to work when I wake the PC I have to click power botton for a sec every time I restart PC, or if it goes to sleep, in order to get screen back to normal. AppleHDA_ALC293.kext.zip installed with KextWizzard, speakers are available system preferences, but still no audio…. Another update: when PC wakes from Sleep, there is a pop up about ejected USB device. I generated SSDT.aml and put it to EFI/Clover/ACPI/Patched I uploaded my EFI folder and all screenshots to dropbox, feel free to download it: https://www.dropbox.com/sh/ns120hva5m49ecd/AADpQmt_9eCAJoF4SmexBcIIa?dl=0 Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted September 29, 2016 Moderators Share Posted September 29, 2016 you have an error, rerun the last 2 commands until you have success Child process /usr/sbin/kextcache[569] exited with status 77. To fix audio, enable ResetHDA in Config file To fix wireless, add additional patch to KextToPatch Comment AirPortBrcm4360 - fcvo Disabled Find gflSqgAAdSk= Name AirPortBrcm4360 Replace gflSqgAAZpA= To fix the screen during boot, Enable Legacy Rom Option in BIOs The USB popup is normal if you have USB plugged in before sleep I have everything working, will post a guide when I have some time, been sick with the flu.

Administrators Hervé Posted September 29, 2016 Administrators Share Posted September 29, 2016 Error 77 -> your cache is not rebuilt properly. Redo the touch + kextcache commands or use the following alternative kextcache command: sudo kextcache -system-prelinked-kernel `Pop-up message about an external USB device would be normal after Sleep/Wake: power is cut off USB ports at Sleep, unless you opt for the option to retain power to USB when computer is asleep but that's usually limited to having the computer plugged to mains.

seeker_pl Posted September 30, 2016 Share Posted September 30, 2016 Wow, Guys! This solved most of my problems, actually two remains. First touch-pad after PC wakes from sleep and auto unlock with Apple Watch. Do you have any advice for Touch-Pad? Auto unlock act strange, whenever I try to enable it in System Preferences I get error regarding two-factor authentication. I tried to disable it and enable it again, but same problem. Is there any difference between two step and two-factor authentication? Link to comment Share on other sites More sharing options...

How do you handle Brightness Control and Trackstick Scrolling?Karabiner is not available yet for Sierra, or we have to wait? Link to comment Share on other sites More sharing options...
