Thanks of all help getting up and running machine. It's been getting better and better but so far one major issue keeps annoying usage.
Problem is that everything visible freezes but if there was video running background.. i can still hear soundtrack without problem and i can move cursor but nothing is responding anymore and needs force shut down.
I am too hard to give up at anything so i make this thread to continue what people keeps doing around internet trying solve this issue with HD3000.
My setup:
Did open some hidden bios options and changed Gtt size, aperture size, Gfx low power mode.. and so.
i5 version
MacBookPro8,1
12GB ram
Removed whatevergreen
I have got explanations that it could be..
*HD3000 memory bug via Clover.
*Clover nvram emulation (EmuVariableUefi-64.efi)
*Screen EDIS info injection or screen refresh rate mod *For glitches but i have second monitor attached..
*CPU VT-d problem
*HD led blinks so it could be AHCI kext.. *No affect
*Quicklook bug https://discussions.apple.com/thread/8506070
What helps..
*More ram less glitchy.
?
At moment trying different set of HD3000 kexts than HS own ones and yesterday i didn't got it freeze yet but i keep updated.
#UPDATE; Now has been full 5 day working and NO FREEZE crashes. Only glitches... Apart once did happen blackout during day and i didn't have battery so that we wont calculate.
Here is files i used: https://github.com/chris1111/Legacy-Video-patch/tree/master/Legacy-Video-patch/KEXT/InstallKext
AppleIntelHD3000Graphics.kext
AppleIntelHD3000GraphicsGA.plugin
AppleIntelHD3000GraphicsGLDriver.bundle
AppleIntelHD3000GraphicsVADriver.bundle
AppleIntelSNBGraphicsFB.kext
AppleIntelSNBVA.bundle
Seen more than one place issue never solved where HD3000 freezes. Maybe Gt2 bug?
#UPDATE#2; Still crashing but i guess freezing COULD be due sound chip? I bring this up as i can hear sound still some time during freeze. But under Win7 there can come sudden *brrrrr* sound like glitch when i close the program (like video player). Now looking soundcard.
