lisai9093 Posted June 12, 2013 Author Share Posted June 12, 2013 need Smbios.plist Thx for replying. I did have smbios.plist when using chameleon, model is macbookpro 8,1. Clover does not have this file. So what to do next?

lisai9093 Posted June 12, 2013 Author Share Posted June 12, 2013 I think I got this problem. It is probably due to the size of my EFI partition on that disk is smaller than 200MB. The current EFI partition is created by Windows which has default size of 128MB. However Apple use 200MB EFI partition. If I choose another disk which has 200MB EFI, everything works.

You should have a separate drive for each system anyway.

lisai9093 Posted June 14, 2013 Author Share Posted June 14, 2013 You should have a separate drive for each system anyway. Its nothing to do with the driver. I have verified my method yesterday. So it seems that Apple new system is checking my efi partition size before installation. Hope it helps people with similar problem.
