I have Open core 0.6.3 loaded and Big Sur working (thanks for the tip Jake) I can't figure out why ALC255 won't load I can get audio with VoodooHda but can't get audio with every layout ID I tried. This is a test machine, trying to get it working before I upgrade my main machine from clover and Catalina to Big Sur with open core. 11.25.2020 Updated (thank you Jake) Sound working Bluetooth working Facetime working App Store working Wake from sleep goes to black screen, don't know how to turn off sleep in Big S Can't replace Efi so I attached pictures instead and my config.plist E5550 OC 0.6.3 EFI.zip E5550 plist OC 0.6.3.zip

Hi. I new here. I followed Jake Lo's guide on installing OS X El Capitan 10.11.6 on E5550, but no success. I repeated and followed every step but it always failed to load. (Stuck at loading) I searched about this issue but couldn't find anything that would be of any help. I booted with -v in boot args and saw Mac OS version: Not yet set. I had to delete the files in EFI/Clover/ACPI/patched to make it run, but audio, bluetooth, web cam, card reader, & wifi (intel) don't work. I attached a picture that shows the booting process with -v and config file. Any help is appreciated! config.plist.zip

I was finally able to get Sierra running on my E5550, but some problems remain. Working: Graphics, battery indicator, Ethernet Not working: Audio, Bluetooth, Camera, Card reader I followed Jake Lo's guide, but wasn't able to get up and running that way. I had to hack my way through every step it seems. I used EFI_4200.zip and the E5550_A15_Disable_GT820M.zip bootpack. I've copied kext files to Clover and to LE, ran the chmod/chown and cache rebuild. I copied the config.plist from the bootpack download section-by-section into my working file. I finally tracked down the item that seems to be the issue. If I include ACPI\SSDT\DropOem = YES then I am not able to boot. Booting starts, but mid-way through the progress bar, I receive the O- symbol. I am not even sure if that has anything to do with my issue, but that is the only thing that I haven't completed all the way from the guide. I have attached my config file and can send you any other data that you want to see. Any help would be greatly appreciated! I hope I haven't missed something dumb. config.plist.zip

Hi! First of all, I am new here. I searched with Google and with the forum's search engine for E5550 with any OSX topic, but I found nothing. It's quite disappointing. Is anyone here who tried to install OSX on E5550? My notebooks specs are on the attachment. I hope somebody can help me. I'm familiar with Linux, so Terminal and another CLI based tools or methods are good for me. I have basic knowledge for Clover and for the installation method, earlier I installed Yosemite for Desktop PC with success (except audio). One more thing: I am using a second (external monitor) on VGA port, and an ASUS Xonar U3 soundcard. Thanks guys, vitat6atlan
