jfrank58 Posted January 8, 2021 Share Posted January 8, 2021 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 config.plist.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 8, 2021 Moderators Share Posted January 8, 2021 Please post full system's specs. Start with... is it an Inspiron or Latitude or Vostro? Link to comment Share on other sites More sharing options...
jfrank58 Posted January 9, 2021 Author Share Posted January 9, 2021 This is a Latitude 3580 with i5-7200U CPU, 16GB RAM and a Kingston SSD. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted January 9, 2021 Administrators Share Posted January 9, 2021 I'd say your SMBIOS setup is not complete and incorrect. Make sure to fully complete that part of the configuration process. https://dortania.github.io/OpenCore-Install-Guide/config.plist/kaby-lake.html#platforminfo Link to comment Share on other sites More sharing options...
jfrank58 Posted January 9, 2021 Author Share Posted January 9, 2021 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 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted January 9, 2021 Administrators Share Posted January 9, 2021 As I said, your SMBIOS is incorrect and your config file may be corrupt (I'm unable to open it with ProperTree app). Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 10, 2021 Moderators Share Posted January 10, 2021 @jfrank58 Give this a try, rename to EFI Assuming it has Intel Wifi/BT combo card Latitude_3580_OC065.zip Link to comment Share on other sites More sharing options...
jfrank58 Posted January 10, 2021 Author Share Posted January 10, 2021 Thank you. Thank you. I think that's going to work. At least I no longer get the "can not install....platform" warning anymore. Can you tell me what I had wrong? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 10, 2021 Moderators Share Posted January 10, 2021 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 Link to comment Share on other sites More sharing options...
