jfmac Posted November 23, 2021 Share Posted November 23, 2021 I installed Yosemite 10.10.3 following this Chameleon guide by Jake Lo; then updated via software update to 10.10.5. All working well, except I can't boot without -f? I have repaired permissions and rebuilt the cache numerous times. The boot screen does not progress beyond this: last 2 lines read: Sound assertion in AppleHDAEngine as line 581 Sound assertion in AppleHDAEngine as line 18170 Attached below is my Extra Directory: 6420Extra.zip All help and suggestions greatly appreciated!

Administrators Hervé Posted November 24, 2021 Administrators Share Posted November 24, 2021 Woaw, old and totally deprecated stuff. Why would you install old Yosemite with Chameleon today? It's all been abandoned for years. The E6x20 laptops can natively run macOS up to High Sierra and you'll find much more recent guides for that. The installation process and DSDT-less bootpack I posted in my E6220 Mojave guide here may be of particular interest to you. Link to comment Share on other sites More sharing options...
jfmac Posted November 24, 2021 Author Share Posted November 24, 2021 Hello Herve, initially l installed High Sierra (clover), but could not overcome freeze and crash of apps, especially safari. Usually would happen when moving windows. Tried everything I found through search, except switching out LCD . I already had the usb Yosemite install from a few years ago. Anyway… probably TMI. So that said, do you know what’s wrong with what I’ve done? Sometimes after a few years you forget how you did WHAT? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted November 24, 2021 Administrators Share Posted November 24, 2021 Absolutely no idea. I've heard of such issues on HD3000 systems but never on the Latitude E6x20 models. If you want further assistance, post the Clover setup you were using + your E6420 full specs. Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted November 24, 2021 Administrators Share Posted November 24, 2021 if you put anything in S/L/E try moving it to L/E instead and then repair permissions and rebuild the caches. Link to comment Share on other sites More sharing options...
jfmac Posted November 25, 2021 Author Share Posted November 25, 2021 Thank you Bronxteck, actually I needed to put FakeSMC in /S/L/E & my org.chameleon.Boot.plist was for newer os. The plist also didn’t tell boot the location of DSDT. Anyway all good now! Link to comment Share on other sites More sharing options...
