Hello MacNB,
Good to hear you are still rocking the Inspiron 530, it gives me hope. I had to put my Hackintosh on back burner for a while, but recently dusted it off and looking to install Catalina. I never got around to getting my EFI installed on my SSD, had to boot from USB.
Would you recommend trying the Vanilla Opencore installation method, or going the Clover method? I just installed a GT635 (GK208 Kepler) and been trying to follow the vanilla guides. Or is it easier to follow the same steps as Oneof4?
If you are familiar with Clover - stick with it.
If you willing to learn and put the effort in then it is worth moving to OpenCore - so much quicker to boot.
I have moved to OpenCore on both my desktops. On my Z77 system with working NVRAM, with OC it behaves just like a real Mac. Updates just happen - no need to to ever drop into the boot menus to select the macOS Installer boot disk, etc, etc. It's totally transparent which was not always the case with Clover on my system. So on newer systems it's definitely worth moving to OpenCore. On legacy systems (like the 530) without UEFI and without NVRAM, it's more work but worth the effort - you can even boot macOS Tiger !
On the Dell 530, I had to modify my DSDT.aml so that I could boot Windows 10 as well. Without these mods, Windows boot would fail - with ACPI_BIOS_ERROR blue screen. The DSDT.aml I posted in this thread has those mods.
Also, in my DSDT.aml (not the one I posted) I had ACPI code to enable the Nvidia GT 730 GPU - this is required for OpenCore since OpenCore does NOT have the Clover equivalent of Graphics/Inject/nvidia=YES in the config.plist.
Apart from those two changes, it's a vanilla OpenCore Legacy Install.
There's good guide
here - it's long but detailed.
In that guide there's a section on
converting from Clover to OpenCore.
So, the choice is yours - you want to learn to hack or just want an easy life
