#2055791 Lenovo ThinkPad T420 with UEFI Only

Posted by tluck on 27 August 2014 - 11:45 AM

@veeryes - replace intel wifi with OS X supported wifi card and then flash the box with a modified whitelist bios so it will not reject the card. these cards are often sold rebranded by HP, Dell etc on eBay.  here are 3 options (i chose the 1st one) Atheros AR5BHB92 - dual-band: 2.4GHz + 5GHz. МасOS up to 150 Mbps on 2.4GHz and up to 300 Mbps on 5GHz, Windows up to 300 Mbps on both bands. Broadcom BCM94322HM8L - dual-band: 2.4GHz + 5GHz. МасOS up to 150 Mbps on 2.4GHz and up to 300 Mbps on 5GHz, Windows up to 300 Mbps on both bands.Atheros AR5B93- single-band: 2.4GHz only. МасOS up to 150 Mbps, Windows up to 300 Mbps. @adrenalationthis worked for me: added a credit card to my appleID account.remove all network location/interface definitions from the |System Network panelrm        /Library/Preferences/SystemConfiguration/NetworkInterfaces.plistreboot and redo network interface definitions for ethernet and then wifi (i know i know - so...

@glasgreat - you would probably only have to change DualLink=0 to DualLink=1 the difference between 1366x768 config.plist the 1600x900 config.plist are 2 items:1) DualLink value2) EDID only for 1600x900 screen (  alternate EDID is needed replace bogus/broken EDID from bios/panel with a good one for this panel size ) @viraf - it maybe the old bios only supports 2GB usb or less? i am sure you have a good reason not to upgrade your bios, because i can't think of one.

@tetonne.   running windows in a VM while using OS X is way better IMO!!!  i had problems with IDE in VMware Fusion, so i use SCSI disks.  in your case disk0 and partition 4 /Applications/VMware\ Fusion.app/Contents/Library/vmware-rawdiskCreator create /dev/disk0 4 "Disk1" lsisas then my disks are defined like this in the vmx file tluck@Toms-Mac /Local/W7x64-vmdk.vmwarevm$ grep scsi Windows\ 7\ x64.vmxscsi0.pciSlotNumber = "160"scsi0.present = "TRUE"scsi0.sasWWID = "50 05 05 64 59 da c3 60"scsi0.virtualDev = "lsisas1068"scsi0:0.fileName = "Disk1.vmdk"scsi0:0.present = "TRUE"scsi0:0.redo = ""scsi0:1.fileName = "Disk2.vmdk"scsi0:1.present = "TRUE"scsi0:1.redo = ""scsi0:2.fileName = "Disk3.vmdk"scsi0:2.present = "TRUE"scsi0:2.redo = ""

@adrenalation -  perhaps the inability to load the kext is a permission problem? how did you install the kext?i would reinstall the kext with kextutility or fix perms and do this following so it will rebuild the caches.sudo touch /System/Library/Extensions@manwe150  i will try the DMAR table drop to see what that does for us. i don't really know how measure the effect of VT-d as fusion and/or virtual box runs for me. i have a windows VM that runs from a physical VMDK (i.e. the vmdk reads/writes the partition. another one is sitting on an SSD (and start up is very fast!).

@all - Posted latest pack - updated for Yosemite DP6. Clover UEFI on T420 Guidefairly minor changes in the pack. yosemite has been very stable for me over the last few weeks. just a few random finder or mdutil crashes. Like Cowboy Mike, I just ran the app store updater to download and install DP6 - ran without any issue. Had to replace/patch AppleHDA and Broadcom kexts as they were modified again. Note:the Yosemite Recovery HD has some odd things that can be easily fixed. (seems to happens on real macs too.)mount it and you can remove the 2 bogus folders, keeping just the com.apple.recover.boot folder (and its contents) 21-August-2014 - 10.10 DP6/Beta UpdateClover updated to v2829 v2830FakeSMC updated to 6.10.1323ACPIBacklight.kext - v2.0.3 - with modified code to fix/workaround for LCD brightness in Yosemite.added drop table MCFG for Nvidia/Optimus (mixed gfx)added 10.10 kext folder (AppleHDA.kext and BroadcomBluetooth kexts are different than DP5...

I'm on vacation for a few days and don't have my hack with me to look at what the device tree lists etc. i have a similar  wifi card  AR5BHB92 - but it seems for your card you need to add an entry to pick up your id  it simply consists of adding the card PCI Vendor id/Product id 0x168c/0x002b to the list of ids defined in the plist file inside the kext:./IO80211Family.kext/Contents/PlugIns/AirPortAtheros40.kextthese are what are there.           IONameMatch = Array {                pci168c,30                pci168c,2a                pci106b,0086                pci168c,1c                pci168c,23                pci168c,24

Posted by tluck on 04 August 2014 - 03:32 PM

@Cowboy Mike - hard to say but it seems like FakeSMC did not load? something about duplicate. is this a fresh install or install onto of mavericks where there are kexts already in /S/L/E. clover with the HFS-plus driver should be able to detect if FakeSMC is there or not and load from ESP if not on the HD.- can't tell from the image what happen or not earlier.- i would NOT try don't boot without caches yet on yosemite - let yosemite rebuild them when up and running. Note: netkas just updated his FakeSMC to 6.10.1323 (vs 1315) for yosemite. i have not updated the bundle yet.

@Mittles  hmm not sure. but make sure the BIOS settings are Virtualization settings are set to not use VT-d. to get a better idea of what is going on you can boot the installer in verbose mode by hitting space when selecting the the USB installer in Clover. scroll down and hit return on "verbose". @Cowboy Mike  sure - i will post a new zip clover bundle which includes kexts for 10.10. stay tuned.

Posted by tluck on 21 July 2014 - 10:18 PM

@Fabiano_Nomad - thats cool. then you should be able to take the bits out the T420 (my DSDT.dsl ) and put in your DSDT add any missing pieces. at one point i thought i posted a diffs file showing original T420 dsdt compared to final dsdt to help will all the editing. if it helps, i can diff the DSDT clover generates vs mine to provide the delta on battery and so on. @tetonne - to boot windows via UEFI (from HD ESP), you must have the windows boot loader (bootmgfw.efi) and the BCD in /EFI/Microsoft/bootthe BCD must point to your C: drive partition.

Posted by tluck on 20 July 2014 - 07:25 PM

@Fabiano_Nomad - well i see!  as they say: that is a horse of a different color meaning a T420s is a slightly different than the T420. so you could try the config.nodsdt.plist (rename to config.plist and remove the ACPI/patched/dsdt.aml file) to build a patched DSDT for your box. Clover will pull your BIOS DSDT and patch up most things - and just about everything will work except the battery. there may be others that can share their fully patched DSDT for the T420s.
