to upgrade to High Sierra you can typically download and install directly if you are running the lastest clover zip etc. 

i recommend making a usb installer too.

you can clone with dd if you know what you are doing - i used to copy my windows stuff using dd. i use carbon copy for my macOS copy

if you have modded your bios, you may be able to just put in the chip and go.

i use Atheros AR5BHB92 aka 9280 and it works OOTB - no extra kexts etc.

but it is just wifi. bluetooth is a separate chip .

Been there, done that.


I extracted my EDID from linux and injected it in Clover and faked the display ID to match the Color LCD of the Macbook (610 9cf2) and love the Color profile. The default is too cool (bluish)  for my taste.


I still get some glitches with the EDID injection.


i did the same thing for the color profile. different topic.  but it sounds like means you injected/used the same built-in EDID from the LCD that macOS finds. i am talking about replacing the built-in EDID with a modified EDID. can be done with DSDT and/or Clover. That is a use a EDID with different timings, blanking time, spacing etc. the standard LCD edid glitches like crazy and eventually get total gfx freeze (BRSNC in log etc). my guide for Lenovo T420 has examples. I also use EDID with just RGB mode so now I don't get acid wash color flicker on certain apps - was getting that using LCD+External. (thanks vusun).


High Sierra does seem more prone to HD 3000 gfx issues -  as i ran artifact free fro about 3 or 4 years on 10.10, 10.11 and 10.12 without issue. but all of sudden High Sierra has issues?! For example, I was using EDID injection on my mini-mac5 hack for years now by adding AAPL00,override-no-connect "trick" for headless boot - but had to remove that otherwise i get wicked artifacts. oh well.

How are you doing with the graphical glitches of the HD3000? do you have any??


I have 2 systems with HD 3000 and my experience is that glitches and/or gfx artifacts (random black lines/spots etc) can be caused by an improper EDID - or conversely fixed by an alternate/proper EDID. without going into detail, besides EDID there are other causes of glitches and there are plenty of other threads that discuss this topic.

I need some assistance with my laptop ASUS U46E (Intel HD 3000):


I'm now using Clover r4369 with AptioFix2 and calculated my slide and found the value of 0x201 (513). I can even boot without a slide value or with that slide=513 but I can't reboot. As soon as I reboot I get the prohibited sign or the print-f work message.


Attached are my memmap and boot.log.


My nvram was already working without any help in UEFI mode. I still can't get rid of some graphic artifacts like lines on the screen that appear when I'm starting using programs.


Thanks in advance!






I was you, I might try slide of 257 -> targets this area:
