Re: writing EDK compatible application.

[Amit kumar <akamit91@hotmail.com>]

Hi,
Yes intact it’s MacBook, but is there another way to do it without UEFI shell. In edk2/shellpkgbin are 2.2+, even shell fails to execute on Mac.
Although efi shell 1.0 works. Is there a to do it without shell ?
Thanks
Amit
