For recommended BIOS settings, see here.

 

These guides are for Vostro200 desktop computers fitted with a Wolfdale Core2Duo CPU (or Wolfdale-DP dual core Xeon CPU) that includes SSE4.1 instructions set. Conroe CPUs do not include these and are therefore unsuitable for macOS, they can only run OS X up to El Capitan.

 

From Mojave onwards, macOS only supports nVidia Kepler cards. As such, High Sierra 10.13 is the end of the road for Pascal cards such as the GT1030, knowing that these are only supported with the nVidia Web Driver due to lack of native drivers.

 

NB: Wolfdale-DP CPUs may require adjusting CPU clock rate parameter to highest multiplier in BIOS for proper CPU SpeedStep to work. Running on a Wolfdale-DP Xeon dual core CPU may also require the use of additional boot arg npci=0x2000 or npci=0x3000 to avoid boot freeze and system hard reset. It certainly did on my Vostro200 (but then again my X5270 was an ES model...).

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:
    • Install Clover in the ESP

    • Boot Sectors -> Install boot0af in MBR

    • Clover for BIOS (legacy) booting -> Clover EFI 64-bits SATA

    • BIOS Drivers, 64 bit -> FSInject-64 / ApfsDriverLoader-64 / AppleImageLoader-64

    • BIOS Drivers, 64 bit -> GrubEXFAT-64 / GrubNTFS-64 (both optional only)

    • Themes (optional only)
    • Install Clover PrefPane (optional only)
  • you may use version r4689 attached below or any subsequent version available at Dids' Github repo
  • once Clover is installed, launch Clover Configurator app and mount the freshly created EFI partition of the USB installer
  • open this EFI partition and transfer the files & folders from the Vostro200 High Sierra Clover pack below to the EFI/Clover folder of the EFI partition

 

2) 10.13 installation

  • boot the High Sierra USB installer and wait until you get to the language menu; it'll get there.
  • 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 installation 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 Vostro200 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, allowing all apps download from anywhere, changing all serial numbers, etc.

This is a problem for installing Big Sur from scratch with a USB installer because, in legacy BIOS mode, OpenCore does not appear capable to dynamically obtain the volume UUID of the temporary MacOS installer partition/volume (created during the installation process) and properly define an essential parameter called msu-product-url. This causes the installation process to fail proper execution and, instead, triggers computer reset + continuous boot loop of the temporary volume, the installation therefore never reaching completion. A workaround to this problem is to install Big Sur as an upgrade of an existing Catalina installation.

 

When installing Big Sur as an upgrade of Catalina, the temp installation will be created on the existing Catalina Data volume whose UUID can be readily obtained and passed through NVRAM parameter msu-product-url to the installation process. This was described in this thread by pac-man at InsanelyMac, credits to him. Basically, the UUID of the Catalina Data volume is obtained through the diskutil line command and the resulting value is used to create a fully-defined path for the temp installation volume that is stored in NVRAM parameter msu-product-url. This NVRAM parameter is essential to complete the installation process.

 

Please note that installing Big Sur on this old desktop PC takes a substantial amount time to complete (even on a SATA SSD) so set aside a few hours...

 

1) Preparation

  • OpenCore needs to be setup in legacy mode to boot the Vostro 200 computer, lack of UEFI BIOS mode oblige. This is well documented on the Dortania OpenCore GitHub repo which I invite everyone to refer to.
  • the following OC 0.6.5 EFI folder may be used on the existing disk's EFI partition or on a USB key as bootloader to reboot the system during the Big Sur installation phases, then boot Big Sur once it has been fully installed:
  • key elements to note in that config are:
    • the IOHIDFamily kext patch applied to the _isSingleUser function; it's required to obtain working USB keyboard & mouse, they don't work without the patch. This is detailed in the Dortania's documentation.
    • additional msu-product-url parameter added to NVRAM->7C436110-AB2A-4BBB-A880-FE41995C9F82->LegacySchema as per pac-man's thread at InsanelyMac.

 

2) 11.x installation

  • from an existing Catalina installation (can be a Clover-based one), download a copy of Big Sur installation package.
  • ensure you have emulated NVRAM working and define msu-product-url parameter as follows through Terminal:
sudo nvram msu-product-url="msu-product-url://$(diskutil info /System/Volumes/Data | grep "Volume UUID" | awk '{print $3}')/macOS%2520Install%2520Data"
  • run the Big Sur installation package and proceed with installation on your Catalina disk/volume/partition as offered by the installer app.
  • the Big Sur files will be copied over and this may take a lot of time (could be anything from 40mins to 1hr).
  • on 1st and all subsequent reboots, make sure to use OpenCore and the EFI folder/config setup offered above.
  • :excl: Do not clean or reset NVRAM when rebooting with OpenCore during installation as this may remove the necessary msu-product-url parameter.
  • the whole installation process will normally require 3 or 4 reboots to complete and this make take anything like 1hr. 

 

3) Post-installation tuning

  • once the Big Sur installation has completed and Big Sur first boots, complete the initial configuration tuning. Here too, this may take an unusual and very long time; just hang in there.
  • once at the Big Sur desktop, mount your disk's EFI partition and copy the OpenCore EFI folder as necessary/appropriate in order to boot Big Sur via OpenCore.
  • proceed with usual macOS fine-tuning (wireless setup, hibernation disabling, refresh of serial numbers, etc.).

 

NB: Contrary to pac-man's suggestion to remove the msu-product-url from NVRAM after installation, I strongly recommended to retain it because it'll be required for each Big Sur update.

Revised DSDT following replacement of DW1510 wireless card with an Apple BCM94360CS2 causing built-in Bluetooth to break sleep. All Ok once the UHC ports were patched so that their individual _PWR statements was adjusted from:

                Name (_PRW, Package (0x02)  // _PRW: Power Resources for Wake
                {
                    0x0nn,      // where nn=03/04/0C/0E/05/20 for UHC1/UHC2/UHC3/UHC4/UHC5/UHC6 respectively
                    0x03
                })

to:

                Name (_PRW, Package (0x02)  // _PRW: Power Resources for Wake
                {
                    0x0D, 
                    0x03
                })

as per USB2.0 EH0x devices.
