Missing or deformed Apple logos…

I compiled the IOGraphicsFamily.kext yesterday and added debug output to located the root cause of missing and deformed Apple logos during the first, second and third boot stages, and I think to have located the problem.

I’m now working on a solution without adding workarounds like patching the kext to simulate verbose boot ups et all. However. I am still very busy with something else so you will need to wait for me having the time for it. Will report back as soon as I have more news for you. Hopefully sometime next week.

  1. I am very interested in the ability to replace the apple logo, I only need to replace logos 2 and 3. I don’t care about the disk encryption boot logo. We run these computers as kiosks and rebranding or unbending is something that we are interested in. So even just removing the logo would suffice for our use. Any ideas how to get this in 10.11 or 10.10?

    • Hi Scott,

      I haven’t really looked into this, but I know that the LZVN compressed Apple logos can be found in:

      1.) boot(base).efi
      2.) the (prelinked)kernel
      3.) IOFamilyGraphics.lext
      4.) /usr/standalone/i386/EfiLoginUI/appleLogo.efires

      But there ought to be a simpler way to get this done.
