Hello. Long time lurker, first time poster. Hope I'm not double posting, but I haven't been able to find an answer to my question (I DID look through the how-to-build-yr-theme section) which is: all I want to do is replace the apple logo above the spinning kernel wheel thingy on a hackintoshed dell mini 10v. I've tried simply replacing the apple boot.png with my desired choice, but no dice. Word on the street is that legacy logo needs to be changed to off. However, even though I've changed the permissions to read & write after trying to save the com.apple.boot.plist in text edit, I get a "cannot be saved" announcement. Help or advice greatly appreciated and please accept my noobie apologies if this is posted in the wrong spot !
I am making the assumption that you are using Chameleon to boot your system and it is using a theme. Based on that assumption, I can tell you how I changed my boot image.
I happen to have used a png file file I found in the Themes area of this forum. It is an apple shape with a skull appearance. I opened a terminal session and changed into my /Extra/Themes directory. Then change into the directory for the theme I was using with Chameleon.
Depending on the file permissions, this work may need to be done with admin authority. For that reason, I normally change to admin authority at the start.
Enter
sudo -s
followed by the enter key and then supply your password.
The next step was to save the original boot.png file located there.
cp boot.png boot-bkup.png
Then, copy in the new file and replace the old boot.png file.
cp -f /Extra/Themes/skull.png ./boot.png
That was all that was required. The next time I re-booted the system it had the skull shaped boot image. Hope this helps.
Good luck.
