  1. Lenovo ThinkPad T420 with UEFI Only

    The T420 Clover Install Guide seems to be here: T420 Clover Guide
  2. Lenovo ThinkPad T420 with UEFI Only

    El Cap zip https://www.insanelymac.com/forum/applications/core/interface/file/attachment.php?id=240230 Sierra works quite well too. (current zip supports it). High Sierra is doing great on one of my T420 systems - the one that has an LG display vs not-very-good-at-all AUO display.
  3. Lenovo ThinkPad T420 with UEFI Only

    hmm. seems like you are using Chameleon? i see references to loading of config and kexts from /Extra ??? otherwise, maybe you could copy the already installed snow leopard from your real mac to a HD partition for your T420 system?
  4. Lenovo ThinkPad T420 with UEFI Only

    this is expected since VGA is not an active signal.
  5. Lenovo ThinkPad T420 with UEFI Only

    @ASROCK_IIfxThe first OS I put on the T420 was Mountain Lion 10.8. Are there AppleIntelH3000Graphics kexts/drivers in snow leopard? Otherwise you will left wih using the basic video driver for the VESA sizes.
  6. Lenovo ThinkPad T420 with UEFI Only

    well on High Sierra, I have 2 T420 systems. One has an AUO LCD display and has freezes. and the other has LG LCD display (replaced the original AUO) and works great.

    @fireROR - odd, the DP on my system works? i use the DP to connect to my HP monitor. what happens when you attach the DP cable? it should flash and recognize something attached? not sure about USB wake. i have not tried it. i use BT mouse and keyboard.

    @rollitab - For the T420, an OS downgrade is under the constraints or process as a real mac. so you can follow the recipes posted in a variety of locations. but most seem to involve an erase, (clean full) install and restore of data/apps what issues are you seeing with High Sierra. ? somez is seeing some issues - but does not seem to be the BRSYNC/Hang problem common with HD 3000 - seems to be a different issue. But on one of my systems I had some gfx/hangs with BRSYNC/VRSYNC - but since I have reverted the graphics kexts to the Sierra versions, so far so good. sleep/wake ok for me. LED power light goes from slow on/off during sleep to on for wake - moon icon on lid switches to battery icon for wake.

    @jus12 - hmm... i will double check on the LED after sleep when I get home on tonight.
  10. Lenovo ThinkPad T420 with UEFI Only

    @jus12 - hmm. strange - there is fix in the DSDT that address this issue - reset LED upon wake from sleep. so i dont know why it would still flash? i presume you have the custom DSDT in place?
  11. Lenovo ThinkPad T420 with UEFI Only

    @goodguess. seem like the ACPIsensor was the reason for KP? can remove it if you still have issues - its a non-essential fakesmc plugin @somez - here is another idea to fix graphics issues with High Sierra. I was getting some black lines so I have reverted the Graphics Kexts to the Sierra versions. so far no issues. $ ls -ld /Library/Extensions/AppleIntel* drwxr-xr-x 3 root wheel 96 Apr 14 2017 /Library/Extensions/AppleIntelHD3000Graphics.kext drwxr-xr-x 3 root wheel 96 Apr 14 2017 /Library/Extensions/AppleIntelHD3000GraphicsGA.plugin drwxr-xr-x 3 root wheel 96 Apr 14 2017 /Library/Extensions/AppleIntelHD3000GraphicsGLDriver.bundle drwxr-xr-x 3 root wheel 96 Apr 14 2017 /Library/Extensions/AppleIntelHD3000GraphicsVADriver.bundle drwxr-xr-x 3 root wheel 96 Apr 14 2017 /Library/Extensions/AppleIntelSNBGraphicsFB.kext drwxr-xr-x 3 root wheel 96 Apr 14 2017 /Library/Extensions/AppleIntelSNBVA.bundle so to make these load instead of the standard ones, i edited the Info.plist and changed all the versions from 10.x.x to 100.x.x $ kextstat |grep -i graph 93 14 0xffffff7f824b1000 0x49000 0x49000 com.apple.iokit.IOGraphicsFamily (519.13) 0C5824DB-F0E8-3C89-90FF-32400837361C <12 7 5 4 3 1> 99 0 0xffffff7f82531000 0x2e000 0x2e000 com.apple.driver.AppleIntelSNBGraphicsFB (100.0.2) 4651D99C-251F-319C-A742-FE237C8CD3A3 <93 12 11 7 6 5 4 3 1> 120 3 0xffffff7f8293a000 0x9000 0x9000 com.apple.AppleGraphicsDeviceControl (3.18.44) 02233606-BC28-33FA-AB6F-7D86206B8394 <93 12 7 6 5 4 3 1> 122 0 0xffffff7f82948000 0x63000 0x63000 com.apple.driver.AppleIntelHD3000Graphics (100.0.2) BF52C5F1-7F69-35F4-935F-3F5F237AC46C <93 12 7 5 4 3 1> 128 1 0xffffff7f82bc0000 0x3000 0x3000 com.apple.driver.AppleGraphicsControl (3.18.44) 6EA0D4AD-6E3C-37F3-B2EA-13FE0F7B8545 <7 5 4 3 1>
  12. Desktop Intel HD 3000 Graphics

    i just noticed on my HD 3000 Desktop H610 with I3-2125 ( minimac5,1) box I am getting small spots and speckles on menu bar and menus etc ? not the more typically black lines or common glithces. i checked on 10.12.6 and 10.13.3 - same thing?. I started using this box again but it did have this about a year ago! Anybody else seen this type of thing lately?
  13. Lenovo ThinkPad T420 with UEFI Only

    I have no idea why High Sierra is glitchy. my mini-mac-hack is a HD3000 and I am getting speckles and lines on that box now - after 3 years (and OS versions) without issue. My son's T420 is getting BRSYNC on occasion too. @rolitab - the current zip supports sierra and high sierra. my t420 boots Sierra and High Sierra from the same disk.
  14. Lenovo ThinkPad T420 with UEFI Only

    ok. good news. so can share what is different in your EDID vs older one?
  15. Lenovo ThinkPad T420 with UEFI Only

    @somez - i just posted a new zip/release - key item is a new EDID in the 1600x900 config. - the old one is in the .alt. files. perhaps try this one?
