Dell XPS 720 what is a compatible mac os that would work

[Squaredudes2]

the ethernet controller is the broadcom NetXtreme 57xx gigabit controller
PCI\VEN_14E4&DEV_167A&SUBSYS_01E11028&REV_02
PCI\VEN_14E4&DEV_167A&SUBSYS_01E11028
PCI\VEN_14E4&DEV_167A&CC_020000
PCI\VEN_14E4&DEV_167A&CC_0200

the audio codecs are
HDAUDIO\FUNC_01&VEN_8384&DEV_7618&SUBSYS_102801E1&REV_1002
HDAUDIO\FUNC_01&VEN_8384&DEV_7618&SUBSYS_102801E1
here is a screenshot of the audio codacs too

The Device ID is 0x167A. Which I think was a supported Broadcom Ethernet device in macOS's native ethernet kexts, IIRC.

So the three Ethernet kexts you have in your /EFI/CLOVER/kexts/Other folder are not required.

Highlighted kexts can and should be removed.

The Audio Codec is a STAC9200 which AppleALC.kext supports when you use layout-id=11. Well it work for another Dell system using the same Audio codec, so it has a good chance of working with yours.

Can you extract and post a copy of your system DSDT.aml so I can check a few elements that may need patching or renaming before macOS will run on your old Dell system.

If you download Corpnewt's SSDTTime script and use it in Windows, you can extract the DSDT.aml fairly easily. Link below.

Select the green coloured button named 'Code' and select download as Zip.

You may need to download and install Python for the script to work.

Turns out your Kentsfield/Conroe CPU can only run macOS up to El Capitan (10.11.6) natively, using the iMac7,1 SMBIOS. As it lacks the SSE4 instruction set, which all newer releases of macOS require.

Is running El Capitan what you want?
If you want a newer release you need to use a different/newer system to do so.

A secondhand Dell OptiPlex system might do the trick. These are available on eBay for under £100. You could still use the Nvidia GT 730 in the new system.

OK, so based on what I have read I suggest you download OS X El Capitan from the Apple support link below.

How to download and install macOS – Apple Support (UK)

Download and install current or previous versions of the Mac operating system on compatible Mac computers.

support.apple.com

I have been playing with your Clover EFI folder some, tidying it up and adding a few SSDT's, patches etc. which I think will help.

So your EFI folder contents have gone from this:

Current EFI folder contents.

To this:

Revised EFI folder contents.

This includes a kext that I recall working with Broadcom 57XX Ethernet controllers. Some SSDT's that I created from your DSDT.aml and a few companion patches to make the SSDT's work.

See if this EFI helps once you have created your El Capitan installer.
