I noticed some weird behavior with macOS High Sierra. This system was working just fine on Sierra 10.12.5, until I decided to update to High Sierra (10.13.3). The upgrade process went mostly fine I guess, but it got stuck in an infinite spinning wheel which would just keep overlapping. I went into verbose mode, and sure enough, I found "IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0" repeating over and over along with ACM errors... I'm really lost right now. I can boot in recovery mode and safe mode just fine, when the graphics drivers aren't loaded. Web drivers aren't installed. I installed NvidiaGraphicsFixup, but it didn't fix the issue. I tried deleting the native graphics drivers from macOS and installing web drivers, but it didn't help.
Graphics card: ASUS GT630-2GD3 (It's a Fermi card and it needs injection, so I modified my DSDT. Full graphics acceleration worked in Sierra. No Clover injection. I tried using Clover injection instead, I saw no difference.)
CPU: Intel Core i3-3210, iGPU disabled in UEFI
All kexts updated to their latest versions, along with Clover.
For more info, you can refer to the GitHub issue where I posted it. https://github.com/lvs1974/NvidiaGraphicsFixup/issues/3
Any help would be appreciated.
Thank you for your time!
I know veterans from the hackintosh community claimed that Intel HD 2500 is not supported and doesn't work, but mine (mobile version) works with High Sierra, as it did back with every versions since Mountain Lion.
I formerly started a topic here for ElCapitan : http://www.insanelymac.com/forum/topic/316981-intel-hd-graphics-ivy-b-hd-2500-qeci-for-osx-1011/
This should apply to any laptop with following CPU (mobile Ivy Bridge)
My Laptop is an Asus (F301A-RX229H) with an Intel Pentium Mobile 2020M, which includes an Intel HD Graphics, not labelled 2500, but it has 6 execution Units like the 2500, and approximately same clock settings (650-1100) instead of 650-1150 for HD2500. You can check specs here and here. Most importantly, it is identified by bootloader and MacOsX/macOS as "Intel HD Graphics 2500" and uses HD4000 kexts.
Few Graphic Glitches (windows title bar, dock...) solved by reducing transparency in Accessibility Preferences Panel.
I have a Mac Mini 2006 (upgraded) with Intel GMA950 graphics, running MLPostFactor 10.8.5. It is connected to an ASUS VS197 LCD panel using DVI-D. This is natively a 1366x768 panel that is recognized and works fine.
However, the other choices for resolution are 4:3 800x600 and 1024x768, and then the oddballs 832x624 and 1360x768. None of these are useful as a low-resolution widescreen for gaming or watching DVD content. Specifically I want to get access to 848x480 or 854x480, and also 1024x576. SwitchResX makes these choices available, but it doesn't work with a "full screen" game, presumably because the game directly queries OSX Display to get a list of valid resolutions and SwitchResX is bypassing that system instead.
So the solution is obvious: buy a new computer pull the monitor's EDID data, hack it to enable new resolutions, and then tell OSX to use this custom EDID instead of the one retrieved from the monitor.
Following the steps of the EDID injection guide, here is where I am:
* Retrieve EDID, DisplayVendorID etc from ioreg.

* Use an EDID editor to enable new 848x477 and 1024x576 resolutions. (Verify with an online EDID tool, and compare to the previous version)

* Create a new subfolder and plist within /System/Library/Overrides/Display/ containing the new EDID string and monitor name.
Now the problems begin. Even though the plist file is being read (which I know because the Monitor Name has changed in Displays), the custom EDID is not being used. When I dig into IORegExplorer I am able to come up with AAPL00,EDID string and it is the unmodified one read from the monitor. I even tried a plug-and-unplug while OSX is running, and also tried to reset the SMC and NVRAM, but no dice.
Do I need to start digging into DSDT hacking? Is the Intel driver pulling down EDID during boot and I need to override it somewhere else? What am I missing here?
I've been attempting for the past few days to install OS X Mountain Lion on my Lenovo Thinkpad Edge E530 with little success. So much so that I've finally decided I'm probably out of ideas and created this forum post requesting help.
My Laptop Specs are:
Intel Core i3-2328m (Sandy Bridge CPU at 2.2GHZ with support for SSE2 , SSE3 and SSSE3)
500GB Hitachi Z7K500 HDD
Lenovo 627226G Motherboard (Intel HM77 Chipset)
Intel HD Graphics 3000

So far , I've attempted to install iAtkos ML2 and ML3U via USB and so far both have worked up until the first sighting of the apple logo then the laptop restarted. In both cases , I was using a separate USB with chameleon bootloader on but in the instance where I tried to use the onboard bootloader on ML3U , I hit enter and the screen simply remained black.
