  • 8GB DDR4-2133P RAM
  • Intel I219LM Gigabit Ethernet (PCI ven id 0x8086, dev id 0x156f)
  • Whatever M.2 SATA or (compatible) NVME SSD that may be fitted (I used a 256GB Samsung 960 EVO then a 240GB Toshiba RC100)
  • Whatever M.2 2230 wireless card that may be fitted (I initially replaced my original Intel card by a BCM4350-based DW1820a then an Apple BCM94360CS2)
  • Realtek ALC293 (ALC3235) High Def audio (PCI ven id 0x10ec, dev id 0x0293)
  • Realtek RTS525a SD card reader (PCI ven id 0x10ec, dev id 0x525a)
  • Internal-USB Surplus Innovation Technology HD webcam (PCI ven id 0x1bcf, dev id 0x28bd)
  • Alps Alpine V8 TouchPad (model w/o Touchscreen may have V7 Touchpad)
  • 3 x USB 3.0 ports (1 x with power share)
  • 1 x mini DisplayPort
  • 1 x HDMI v1.4
  • 1 x headset/microphone combo jack port
  • 1 x internal M.2 2280 slot (key M, 2 x PCIe 3.0 lanes) for SATA/NVME SSD
  • 1 x internal M.2 2230 WLAN slot (key A/E)
  • 1 x internal M.2 3042 WWAN slot (key B, 1 x PCIe 3.0 lane)

 

NB:

  1. WWAN slot supports M.2 2242 NVME SSDs (eg: Toshiba RC100) which are directly bootable; performance obviously limited due to single PCIe channel. SSD detection can be unreliable at laptop's power-on/reset.
  2. Latitude E7270 can boot from SD card.

For recommended BIOS settings, see here.

 

For proper 4K output, patching BIOS to set DVMT pre-allocated memory to 64MB or 96MB is mandatory. Boot a USB key with ModGrubShell installed on it as explained here and set variable 0x432 to 0x02 or 0x3:

setup_var 0x432 0x3
exit

Default value is 0x1 for 32MB (0x2 is 64MB, 0x03 is 96MB). Once the change is applied, no need to inject patched Framebuffer memory settings (fbmem/stolenmem) as properties in your bootloader's config.

Bear in mind that this DVMT adjustment can be removed by resetting BIOS to default settings.

GeekBench v2.4.4 (32bit) gives a near 8400 rating:

 

E7270_GB32.jpg

 

 

1) 10.13 USB installer creation

  • Using a USB key of 8GB minimum, create a High Sierra USB installer through the following Terminal command:
sudo <path>/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/<USB key>
  • where:
    • <path> = location of High Sierra installation package (eg: /Applications if freshly downloaded)
    • <USB key> = name of formatted USB volume (eg: USB_8GB)

 

The process will take several minutes. Once completed:

  • install Clover bootloader on the USB installer with the following customised settings:
    • Clover for UEFI booting only
    • Install Clover in the ESP
    • UEFI Drivers -> Recommended drivers
      • ApfsDriverLoader / AptioMemoryFix / DataHubDxe / FSInject / HFSPlus / SMCHelper
    • UEFI Drivers -> Human Interface Devices (optional only)
      • PS2MouseDxe / UsbMouseDxe
    • Themes (optional only)
    • Install Clover PrefPane (optional only)

 

2) 10.13 installation

  • boot the High Sierra USB installer
  • at the Clover main menu, select the "Install macOS High Sierra" partition (but don't press [ENTER])
  • press [SPACE], select -v verbose option in the menu, then choose to boot with the selected options
  • proceed with installation, creating & formatting the target High Sierra partition/disk through Disk Utility as/if required
  • on 1st reboot, boot off the USB installer and select the freshly created "macOS install from <target High Sierra partition>"
  • repeat this until this partition is no longer offered and only the target High Sierra partition is left to boot

 

3) Post-Installation tuning

  • Once the target High Sierra partition has booted, complete the 1st boot configuration finalisation
  • Once at the desktop, install Clover bootloader on the High Sierra partition/disk with the customised settings listed above
  • Once Clover is installed, launch Clover Configurator app and mount the freshly created EFI partition of the High Sierra partition/disk
  • Open this EFI partition and transfer the files & folders from the above E7270 High Sierra Clover pack to the EFI/Clover folder of the EFI partition
  • You may then reboot and verify that High Sierra boots off your disk through Clover
  • After that reboot, finalise post-installation tuning actions such as disabling hibernation, disabling GateKeper, changing all serial numbers, etc.

 

Please note that:

  • Clover config of the pack contains HDMI-audio SKL framebuffer patch.
  • Clover config of the pack contains disabled settings for DW1820A wireless card. Enable or remove as appropriate.
  • Caching add-on kexts from /L/E is faster than injecting them from E/C/k/O.
  • After any kexts modification, whether to /S/L/E or to /L/E, repair permissions and rebuild cache.

 

Edit: 17 Jan 2024

  • Revised bootpack with modified SSDT-GPRW patched ACPI table to fix intermittent loss of Bluetooth on wake.

macOS Ventura not natively supporting platforms older than Kaby Lake/HD6x0, it cannot be natively installed and cannot natively run on the Skylake/HD520 Latitude E7270 as used to be the case for earlier versions of the OS. This can however be easily achieved by implementing the following settings which allow keeping a full vanilla installation without calling on add-on patches that would install older kexts, frameworks or other necessary files:

  1. use of Kaby Lake framebuffer 0x59160000 (0x591B0000 may also be used but requires further graphics connectors patching)
  2. fake Kaby Lake HD620 iGPU id 0x5916

This can however be easily achieved by implementing the following settings which allow keeping a full vanilla installation without calling on add-on patches that would install older kexts, frameworks or other necessary files:

  1. use of Kaby Lake framebuffer 0x59160000 (0x591B0000 may also be used but requires further graphics connectors patching)
  2. fake Kaby Lake HD620 iGPU id 0x5916
  3. use Coffee Lake platform SMBIOS MacBookPro15,2
  4. use Whatevergreen v1.6.6/v1.6.7 minimum

 

 

1) 14.x USB installer creation

2) 14.x installation

  • boot the Sonoma USB installer
  • at the Clover main menu, select the "Install macOS Sonoma" partition (but don't press [ENTER])
  • press [SPACE], select -v verbose option in the menu, then choose to boot with the selected options

  • repeat this until this partition is no longer offered and only the target Sonoma partition is left to boot
  • Reboot the target Sonoma partition via your USB installer

 

3) Post-installation tuning

  • Once the target Sonoma partition has booted, complete the 1st boot configuration tuning
  • Once at the desktop, install Clover bootloader on the Sonoma partition/disk with the customised settings listed above
  • Once Clover is installed, launch Clover Configurator app and mount the freshly created EFI partition of the Sonoma partition/disk
  • Open this EFI partition and transfer the files & folders from the above Latitude E7270 Sonoma Clover pack to the EFI/Clover folder
  • You may then reboot and verify that Sonoma boots off your disk through Clover

 

⚠️ For wifi & Bluetooth, you may use any compatible add-on USB dongle. If you opt for a legacy BCM5350, BCM4360 or BCM43602 wireless card, you'll need to apply OCLP root patches and ensure you boot with Clover r5157 or later (or with OpenCore of course) in order to bypass vanilla IOSkywalkFamily kext and inject replacement IOSkywalkFamily+ IO80211FamilyLegacy kexts. The Clover config attached to the revised bootpack available above already contains the enabled BlockSkywalk kext patch to that effect and the replacement kexts to inject are provided in the kexts folder. Upon launching the OCLP patcher, you should be immediately asked to apply the relevant wireless root patches. See this thread for full details of the process.

 

Edit: 17 Jan 2024

  • Replaced older Clover version r5153 with version r5157 that supports BlockSkywalk kext patch (required to support legacy wireless cards officially dropped in Sonoma)
  • Revised bootpack with:
    • modified SSDT-GPRW patched ACPI table to fix intermittent loss of Bluetooth on wake.
    • modified Clover config to enable BlockSkywalk kext patch and add -amfi_get_out_of_my_way=1 boot arg
    • added replacement IOSkywalkFamily + older IO80211FamilyLegacy kexts to kexts/Other folder for injection (required to support legacy wireless cards officially dropped in Sonoma)

 

Edit: 10 Mar 2024

  • Revised bootpack #3 with new versions for wireless kexts required for Sonoma 14.4.

 

Edit: 6 Apr 2024

  • Revised bootpack #4 with cleanup of SSDT tables.

Revisited all bootpacks to replace the SSDT-GPRW patched ACPI table. I added a test applicable to all ACPI devices RPxx, specifically  RP05@1C (i.e. WLAN port), to fix an intermittent loss of Bluetooth on wake, requiring Bluetooth to be switched off and on at macOS level (PrefPane or Finder's bar icon) to recover services. This fix applies to combo Wifi/Bluetooth M.2 cards fitted to the WLAN slot.

            If (LEqual (0x69, Arg0))
            {
                Return (Package (0x02)
                {
                    0x69, 
                    Zero
                })
