- Create a full backup of Mojave first.
- Yes you must do this. Catalina 10.15.4 is tricky.
- It may become necessary to restore from backup.
- Follow the Micro Guide here to unlock MSR 0xE2. This is necessary.
- Boot into Mojave and delete all of the following kexts from /Library/Extensions if they exist:
- Empty the trash.
- Rebuild the kernel cache by running Kext Utility. Wait until the button on lower right of the window changes to Quit.
- Find a spare USB flash disk.
- Format the USB disk in Disk Utility:
- Name: Boot Test
- Format: MacOS Extended (Journaled)
- Scheme: GUID Partition Map
- Mount EFI partition of the USB flash disk.
- Follow Step 1 of the Catalina 10.15.4 Mini-Guide except for the 3rd bullet (3rd bullet copies macOS installer to the USB disk, which we don't want).
- Download Clover 5107 or 5108 from the link in the Mini-Guide and follow instructions located there to install Clover to the USB flash disk.
- This will create an EFI folder inside the EFI partition.
- Delete any kexts and drivers that might exist in the new CLOVER/kexts/Other folder and in the CLOVER/drivers/UEFI folder.
- Empty the trash.
- Download ZIP file from the same Catalina Mini-Guide called Catalina 10.15.4 Fresh Install.zip. Do not use the newer May 2020 Update - Catalina 10.15.4 Fresh Install.zip because it will prevent the system from booting. You will find 2 config files there:
- config-Internal-GPU.plist
- config-AMD-GPU.plist
- If you have an AMD GPU, copy your existing RtVariables and SMBIOS sections (only these two sections) from the Mojave config.plist into config-AMD-GPU.plist. Use a text editor like BBEdit or a Plist Editor such as ProperTree to copy those two sections.
- Rename config-AMD-GPU.plist --> to --> config.plist
- If you only have the Intel iGPU, copy your existing RtVariables and SMBIOS sections (only these two sections) from the Mojave config.plist into config-Internal-GPU.plist. Use a text editor like BBEdit or a Plist Editor such as ProperTree to copy those two sections.
- Rename config-Internal-GPU.plist --> to --> config.plist
- Follow remaining instructions in Step 1 of Catalina 10.15.4 Mini-Guide for copying drivers, kexts, and ACPI files from the ZIP to the new CLOVER folder.
- Boot from the USB flash disk by pressing F12 at BIOS splash screen and choosing the USB disk.
- At Clover Boot Menu, select the normal option to boot into macOS Mojave.
- Now attempt an in-place upgrade from Mojave to Catalina 10.15.4 from System Preferences --> Software Update.
- Each time the system reboots during installation, press F12 at BIOS splash screen and choose the USB disk.
- This is critical.
- Please remember it.
- At Clover Boot Menu whenever you find a boot option with the word "Install", select that option.
- For example: Boot macOS Install from <name of Mojave disk>
- As stated in the Catalina 10.15.4 Mini-Guide, copy EFI folder from USB flash disk to EFI partition of the internal Mojave SSD (which has now been upgraded to Catalina).
- Delete the old EFI folder first and empty the trash.
- If the name of your internal macOS SSD contains the word Mojave, you might want to rename it to Catalina.
- But use Disk Utility to rename the disk.
- This is because Catalina separates the System Folder and the User Folder into two separate logical volumes:
- System Volume
- User Volume -- this one is automatically given the suffix "- data"
- Rename the disk as follows:
Miscellaneous:
- If you experience sleep/wake issues, please see this Sleep Aid for Designare Z390.
