[SOLVED] Latitude E5520 macOS 10.12.3 patch DSDT and SSDT


Recommended Posts

Hi Guys. :)


First of all, great forum!  :-P


Now, back to my question... I managed to get Sierra booting and working nearly perfect... I grabbed kexts, DSDTs, SSDTs and config.plist(s) from all off those well known hackintosh forums around the world... until I got to the desktop.  :mrgreen:


So, I know from some reading beside on this long way, that my system is not set up properly to work at best efficiency...

My problem is, that I really do not understand how to patch a DSDT the right way... I need some "initial ignition" ... some helping hand to bring my on the right path of the force... 


Who would be so kind? And what will he or she need for information about my system? :)


(sorry for the {maybe} bad english, I'm not a native english speaker)

I'm running latest version A14 BIOS.




- no standby while closing the lid, but it takes round about 1min until it goes to standby after closing the lid

- shutdown takes round about 1min (black screen, HDD activity)

- slight but noticeable system lags (maybe round about 200ms, mostly when running safari)

- maybe my CPU is not using correct P&C-States (due to wrong CPU in SSDT?) - i3-2310M is my actual CPU

- ethernet (BCM5761 using BCM5722D.kext) has mac-address 00:00:00:00:00 on every second boot


Last but not least... DSDT, SSDT and clover config.plist are not build by my own, i grabbed them somewhere out of the net. And I'm using them unmodified, means I never edited them.  ;)

Hey Jake.


Thx for your work so far. I'll have a deeper look into + testing your package tommorrow.


But before ii do this 2 questions...


1. the kexts from the /kexts/other/LE folder... do i have to put them in my local L/E on the HDD?

2. i can not use one of the SSDT clover extratcted? (origin folder in my attachment, they are from my current system)


Well, need to sleep now... gn8. :)
