Latitude 3580: Unable to install Big Sur


Recommended Posts

Created Open Core EFI as per instructions (I thought) but when I try to boot on my Dell 3580 laptop, I get warning that says "can not install Mac OSX on this platform".

Can someone look at my config.plist and see if you can help guide me?

Thank you

BIOS is set as per instructions. Must be something in config.plist because at one point it booted to certain point, and I changed something in config.plis. Maybe Big Sur just can't be installed on Latitude 3580 with i5

As I said, your SMBIOS is incorrect and your config file may be corrupt (I'm unable to open it with ProperTree app).

I'm not seeing anything obvious other than what Hervé mentioned about incomplete SMBIOS. You need to input serial #, ROM #, UUID...etc

The other difference is your has MBP14,2, I set mine to MBP14,1
