E6440 i7 Catalina freezes after few minutes


Recommended Posts

Hey guys! E6440 i7 12 GB DDR3 A13 Intel&ATI graphics


Last post I made was about a complete failure to get to the installer screen - turned out that motherboard was on the way out and after I replaced it the system gets there no problem. So I'm not a complete idiot! Yay!


I managed to get Catalina booting and everything working (audio, video, mouse) with the help of one of the installer & post installer EFI packs on here. IIRC the post mentioned that SSDTs (or DSDT?) were included to deal with a usb issue. I am guessing that my lack of custom DSDT/SSDT is what is causing these freezes, and I'm planning on diving into producing them when I get the time to dive into that rabbit hole, but I was just wondering if there could be anything else causing this problem. Also booting with ktexts in clover EFI folder, not other suggested system folder.


Thanks for all your help.

For readers...

I had to run that quite a few times to get it to go through right.

Restarted to Clover and pressed F2 and F4 to generate various logs so this script could copy them.

Install required: sudo mount -uw /

Folder was placed on desktop with zip file.

Upgrade Clover to latest v5103

Update Lilu.kex and Whatevergreen.kext to latest

Get rid of GenericUSBXHCI.kext, no use after Yosemite

Replace ACPIBatteryManager.kext with SMCBatteryManager.kext since you're using VirtualSMC. 

ACPIBatteryManager.kext is paired with FakeSMC.kext.


Not sure if sleep and wake works with VoodooHDA, if not, then replace it with AppleALC.kext and use layout-id = 12

Completed those tasks and still randomly freezes after a few minutes run time. Also, sleep doesn't work (HDD light goes wild).


Also tried swapping out VirtualSMC with FakeSMC and no change.


Also after reading about sleep issues the results of the following commands:


pmset -g
ls -la /var/vm
