Yesterday, 05:36 PM

Just got to it last night. No obvious issues so far. but i have been running on yosemite for awhile despite a few bugs in finder and mail.

20-September-2014 - 10.9.5 and 10.10 DP8/Beta Update

  • FakeSMC updated to 6.11.1328
  • Added drop table MCFG for Nvidia/Optimus (mixed gfx)
  • Added drop table DMAR so VT-d does not have to be disabled
  • ACPIBacklight.kext - v2.0.3 - with modified code to fix/workaround for LCD brightness in Yosemite.
  • Updated 10.10 kexts folder (10.10.DP8 AppleHDA and BroadcomBluetooth kexts + Hackintosh Kexts)

@eilatuno -

 

note: these are fake values

run imessage_debug on a mac and you get output something like this:

 

...

2014-09-18 21:06:15.744 imessage_debug[88950:717741] 4D1EDE05-38C7-4A6A-9CC6-4BCCA8B38C14:ROM: <1c2df32ac 4abc>

2014-09-18 21:06:15.745 imessage_debug[88950:717741] 4D1EDE05-38C7-4A6A-9CC6-4BCCA8B38C14:MLB: C02012300UDDDMRAC
...
 
i then put a new section into the config.plist using a plist editor by cutting and pasting the values above and it looks something like this:
 
<key>RtVariables</key>
<dict>
      <key>MLB</key>
      <string>C02012300UDDDMRAC</string>
      <key>ROM</key>
      <data>
      AcLfMqxKvA==
      </data>
</dict>

@eilatuna - i ran a tool called imessage_debug on a real mac to see what are MLB and ROM values it used. and then i have clover inject these instead of coming up with its own values.

 

@IHateAliases - sounds good. there maybe be some differences between the DSDT for a T420 vs T420s. you should not have to drop the MCFG table unless you are having problems with PCI and/or have a 2nd gfx (optimus/nvidia) card.  dropping it didn't seem to bother my system. however, you could remove the MCFG drop lines in the config.plist. hmm.

 

not sure about the double battery thing. again maybe a dsdt thing?  i have not upgraded to 10.9.5 yet. but will do that when i get back home.

New bundle for DP8: Clover UEFI on T420 Guide

 

Just downloaded and installed the update package for DP8 ... which should be pretty much the same as the Beta 3 update if you are on that track. 
 

Nothing particularly new for Mavericks users in this bundle - but feel free to update any custom kexts, etc. This bundle has the 2 updated Apple kexts for 10.10 DP8. Again AppleHDA and the Broadcom bluetooth kext was changed in this DP update.

 

Since I am using a non-Clover generated set of MLB and ROM values, iMessage continued to work fine for me. However, I hope others see the same results that Cowboy Mike reported regarding iMessage or FaceTime!

 

Note: I recommend re-indexing your drives after Yosemite installation - seems to fix up problems with odd space reports and missing files on searches. For example on the system partition you can run:

sudo mdutil -E /

16-September-2014 - 10.10 DP8/Beta Update

  • Clover updated to r2910 (r2890 is latest posted on Sourceforge - either is fine)
  • FakeSMC updated to 6.11.1328
  • Added drop table MCFG for Nvidia/Optimus (mixed gfx)
  • Added drop table DMAR so VT-d does not have to be disabled
  • ACPIBacklight.kext - v2.0.3 - with modified code to fix/workaround for LCD brightness in Yosemite.
  • Added 10.10 kext folder (AppleHDA.kext and BroadcomBluetooth kext are different)
  • Note: To make an Yosemite USB installer, just follow the 10.9 Mavericks method

@d.u.o

 

sorry, i have to ask - did you install the clover zip contents to your GPT formatted HD or USB in the EFI folder?

 

An easy way to boot clover, is to create a GPT/GUID formatted USB.

Take a 4 GB or larger USB and use diskutility to reformat with a single HFS partition (click options to set mode to GPT).

it will actually have 2 partitions.

 

mount the first ESP (named EFI) partition from the USB and copy the zip contents - all of it to the USB /Volumes/EFI location.

 

so you have both folders

/Volumes/EFI/EFI/BOOT and

/Volumes/EFI/EFI/CLOVER

simply:

rename ACPI.1366x768 to ACPI

rename config.1366x768.plist config.plist

 

select USB via F12 to boot up clover

 

the T420 will look at the format of each disk to determine how to boot from it.

if MBR will look for boot0 in the MBR.

if GPT looks for BOOTx64.efi in /EFI/BOOT/

 

if you want to stay with Chameleon thats fine. there is no reason the kexts will not work for that boot loader.

if you are testing yosemite, you may need to add kext-dev-mode=1 to the boot args so it will ignore the custom kext signatures.

 

personally i have not tried an mSATA drive. (I use SATA and SSD.) so can't say why you are having trouble with it.
