GeekBench v2.4.3 (32bit) gives a 3100+ rating:

D830n_T7500_10.9.5_GB32.jpg

 

Once system is installed, you may update Chameleon to a subsequent release such as r2395, r2401 or r2468 for instance. Enoch branch should be a suitable alternative too.

 

Everything required for installation is in the pack below:

 

Post-installation fine-tuning:

  • :excl: GPU performance tuning has been injected into FakeSMC kext and no longer requires additional action at this stage
  • :excl: Disable hibernation: open up Terminal and type the following commands
sudo pmset hibernatemode 0
sudo pmset hibernatefile /dev/null
sudo rm -f /var/vm/sleepimage

2) 10.11 installation

  • Boot the 10.11 USB installer (it may take a little time to kick in) with -f -v boot flags
  • If/when prompted for USB keyboard and/or mouse at installer startup, just press [sPACE] or [ENTER] key
  • At OS X installer main screen, open up Disk Utility in Utilities menu

  • Create your target 10.11 partition and format it as OS X Extended (Journaled)
  • Close Disk Utility and proceed with OS X 10.11 installation as usual

 

3) Post-installation fine-tuning

  • Reboot the 10.11 USB installer (it may take a little time to kick in)
  • If/when prompted for USB keyboard and/or mouse at installer startup, just press [ENTER] or [sPACE] twice
  • At OS X installer main screen, open up Terminal in Utilities menu
  • Verify CoreStorage installation disk mode:
diskutil list
  • If CoreStorage activated for Fusion drive, revert to legacy mode:
diskutil corestorage revert <device> (for example: /dev/disk1)
  • Identify your freshly made 10.11 partition name
df
  • Copy the Extra folder from the USB installer to your identified 10.11 disk partition
cp -R /Extra /Volumes/<your fresly made 10.11 partition name> (for example: cp -R /Extra /Volumes/OSX_disk)
  • Reboot the 10.11 USB installer, press a key at delay bar (or F8) to interrupt boor process and select your freshly made 10.11 disk partition. You'll then be booting El Capitan for the 1st time
  • Complete the 1st boot installation finalisation
  • Once at the 10.11 desktop, run the Enoch r2795 package from your USB installer to install Enoch on your HDD; it should be installed on the 1st partition of the disk
  • Eject the 10.11 USB installer and put it aside
  • :excl: GPU performance tuning has been injected into FakeSMC kext and no longer requires additional action at this stage
  • :excl: Disable hibernation (can be done later, but should be done): open up Terminal and type the following commands
sudo pmset hibernatemode 0
sudo pmset hibernatefile /dev/null
sudo rm -f /var/vm/sleepimage
  • Reboot your finalised El Capitan installation

 

If you want faster boot time with optimised prelinked kernel:

  • copy all kexts from /Extra/Extensions to /Library/Extensions (ignore and acknowledge the permissions-related error messages)
  • repair kexts permissions and rebuild cache
sudo chmod -Rf 755 /L*/E*
sudo chown -Rf 0:0 /L*/E*
sudo touch -f /L*/E*
sudo kextcache -Boot -U /
  • Edit /Extra/kernel.plist and set KernelBooter_kexts parameter to No
<key>KernelBooter_kexts</key>
<string>No</string>
  • Boot time will be faster in that configuration mode
  • El Capitan can subsequently be updated through AppStore updates or combo updates without further tuning action

 

Please note that:

  • the DSDT was modified to rename USB devices to EH01/EH02; failing that, El Capitan does not recognise any USB2.0 ports/devices.
  • USB ports all functional thanks to D830-specific USB_injector kext (DSDT-described ports injected to MBP5,1 profile).
  • VoodooHDA + AppleHDADisabler kexts have to be placed in /L/E in order to load (they don't load from /E/E).
  • Injecting kexts from /E/E with boot option KernelBooter_kexts=Yes is slower than loading cached kexts placed in /S/L/E or /L/E.
  • After any kexts modification, whether to /S/L/E or to /L/E, repair permissions and rebuild cache as detailed above.Enoch-rev.2795.pkg.zip

Please note that:

  • Sierra requires a Penryn CPU with SSE4 instructions set (e.g. T6xxx, T8xxx, T9xxx with FSB 800MHz). Merom CPUs (e.g.: T5xxx, T7xxx) do not have such instructions set and do not allow Sierra installation.
  • Sierra installation is not supported with MBP5,1 SMBIOS profile (although Sierra can subsequently run with that SMBIOS). Hence the switch to MBP7,1 profile. FakeSMC SMC keys + AGPM tuning revised accordingly (GPU (i.e. AGPM) performance tuning has been injected into FakeSMC kext and no longer requires additional action at this stage).
  • the DSDT was modified to rename USB2.0 controllers to EH01/EH02; failing that, Sierra does not recognise any USB2.0 ports/devices.
  • USB ports all functional thanks to D830-specific USB_injector kext (DSDT-described ports injected to MBP7,1 profile).
  • VoodooHDA + AppleHDADisabler kexts have to be placed in /L/E in order to load (they don't load from /E/E).
  • Injecting kexts from /E/E with boot option KernelBooter_kexts=Yes is slower than loading cached kexts placed in /S/L/E or /L/E.
