Hey,
I just can find any spec on ConsoleControl protocol, can you tell what/where to refer ?

Thanks for the suggestion Marvin, I will try switching to text mode.

Well, if EFI Shell 1.0 works, why not use it?
Mac EFI exposes the ConsoleControl protocol, which lets you switch between text and graphics mode.
That might be the reason your text outputs don't show, because graphics is the default mode on Mac EFI,
though I could never test this myself as I lack the hardware.

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

Hey,

The entry point declarations and the calling conventions have not changed
since EFI 1.10, though X64 was not a supported platform for 1.10 if I
remember correctly.
To be honest, I never saw an x64 EFI 1.10 implementation other than
Apple's, though even if it still signals that version, it's actually more UEFI by
now.
I don't own a Mac, so if it's the platform you tested your app on, I can't tell
you why it didn't work, but I would suggest you to run the app from an EFI
Shell.

Marvin.

HI,

I have written a code (say helloworld program ) using edk2 framework,
named the output efi file as BOOTx64.efi and placed it on a removable
media in EFI/BOOT/ directory so that the application is listed in one time
boot menu.
When selected from boot menu it prints "Hello World".
Which works as expected when tested on UEFI 2.3 and above platforms.
But the same code fails to execute on EFI 1.10 platforms. Which i
suppose is the problem with application entry point.
Can somebody suggest me a way so that the application entry function
can be compatible to both the platform. Even when written according
to UEFI 2.5+ Spec ?

Thanks
Amit
