Best Answer SunKi, 11 July 2014 - 11:32 AM

For the Black theme would require another compilation?

yes, because it is just 'for example' ;)

Hi there guys, 

i was wondering if someone managed to boot yosemite with the gray background and the apple logo,

or are we stuck with black screen and progress bar only?

 

Thanks! :)

Does it still show up if you boot your macbook with the kext-dev-mode boot flag?

sudo nvram boot-args=kext-dev-mode=1

The BOOT USB OS X YOSEMITE 10.10 DP.pkg recently released boots like in the video if no verbose mode is activated. I don't know how but it seems possible to hack the Clover config.plist to get it.

Mine is black and no logo. And grey with no logo (at the moment that the logo appears in the video and the bar loads faster) if I boot in verbose. If I boot normally I can't see the bar loading fast before the desktop appear.

 

EDIT: I only see the grey screen booting in verbose mode but setting it by this way (not using config.plist):

sudo nvram boot-args="-v"

And using Clover in Fast mode.

Jesus that thing boots fast! My yosemite boots 5 times slower than my mountain lion installation.


I find the loading bar to remind me off Linux, a few Linux distros have a loading bar like this. It's not bad, but it isn't apple..

Wow, how many speculations here are around :D

I will get some of the facts right:

 

1) Chameleon's Apple boot screen is fake. Everything is drawn entirely by Chameleon. When using Clover, OS X's boot.efi draws it.

2) The Clover video with the apple shows a "fake" apple. The boot process does NOT show it, it pops up after graphics are initialized and the OS is ready to show the login UI. In my case I do NOT see an apple there as my graphics need initialization and thus my screen turns black and on again in mean time. If my gfx would be supported by the boot process (sounds weird indeed), my screen would not turn black and I would see the apple aswell. Apple pretty much renders the boot screen twice.

3) It's not Clover's fault it doesn't show up, as it's drawn by boot.efi. But I think Clover needs to pass a variable over to boot.efi. Why? Because: How would boot.efi even know it should draw the grey or the black version? I don't know how it decides. I'm 100% sure it decides to use the grey version as I get a grey screen after my screen turns on again.

4) Black and grey version? Yes. Some newer Macs got firmware updates and have a black boot screen aswell... with an white Apple.

5) The logos are contained in an efires file. If you're interested, grab them with this script: Yosemite DP1 Includes new EFI images/sound files

5.1) The boot.efi refers to a black Apple logo file... well, two as the others is 2x. However, such a file is not present in the archive. The logo used for "black" EFIs is the generic one without a color name in its file name. Maybe we need a way to edit these files?

 

I'm entirely sure that we should wait for at least DP2 as the appleLogo.efires is entirely new and yet not all Macs got firmware updates. We shall see.

Look into a real mac's ioreg under the display port ("<framebuffername>,@0"), you will find some values called AAPL,grey-page and AAPL,grey-color (or something like that). If you start osx with clover, the grey-color is 00,00,00,00 in ioreg. The zeros means black... So.... maybe this is why we get black screen at boot? I tried to inject proper grey value into there via DSDT but nohing changed, it doesn't got saved in ioreg. Any idea how to change that?
