[SOLVED] Latitude E5520 macOS 10.12.3 patch DSDT and SSDT

Recommended Posts

Hey Jake... 


Damn... looks like I've been pleased too early... :( I was convinced everything is ok after I saw in in terminal (ifconfig) that my mac address wasn't zeroed. And in system-information app I saw that the card is recognised correctly... Unfortunately I didn't had a ethernet cable yesterday to check if a real connection is working... today I tested it and it is not working... :'( the link on the cable is not recognised...


I'll dig deeper on this and will keep you informed here... :)


Well, three additional things I have to add... (the last one is a good thing)


1. I get some ACPI errors, mostly when I boot on battery power (see attached photo)

2. video playback with vlc is laggy, with quicktime it is fluently (HD video recorded with iPhone 6)

3. i modded my E5520 with a keyboard from a Precision M4300... it works :D (just done this because of the backlight)

Hi, can someone upload his latest Clover EFI (within config, DSDT.aml, kexts) + if needed kext for put in /L/E?

I know SSDT must be made with that script for my own :)

PS: I will be implement Sierra on my E5520 (i5).
