Without checking this thread, I mistakenly installed Security Update 2018-002. It really messed up my system. I did replace the kernel with the kernel from the Security Update 2017-005 and was able to boot my system again but I still had problems. (E.g. I could not install the latest version of iTunes (12.7.4) using the Apple installer without seeing a software installation error at the end of the attempted installation).
So I reformatted the drive and started again. This time I used version 14 of pikify and choose the grey screen. Pikify version 14 did install EL Capitan fine but it installed the black boot screen not the grey boot screen that I requested during the installation.
How can I change the colour of the boot screen back to grey from this black boot screen?
I hope I will need to just change a file somewhere.
P.S. I did not install boot64 etc since I no longer see the point in using it. Since I will no longer be installing Apple Security Updates (after Security Update 2017-005) and Auto Updates has been disabled, it is unlikely boot.efi will ever
There are many ways of getting the correct background colour.
Pike hard coded it. There are two versions of the boot.efi file, one with the grey background, the other with the black background.
Post #1 of this thread points you to Pike’s site where you can download one or both files. Simply copy your choice into the right place(s)
OR
If you used my Pikify script, there are copies in the folder
OR
If you used the App, there are copies in the app/Contents/Resources folder
OR
If you have Boot64 installed there are copies in /Library/Application Support/Boot64
OR
If you have CapitanPikeFix installed, there are copies in /usr/standalone/i386
P.S.
There’s a bug in Boot64 version 3 it always copies the grey background version (sorry folks - I fixed it many moons ago but never bothered to release the update because nobody ever noticed!)
If you have Boot64 installed, you can run this command from the terminal
/Library/Application\ Support/Boot64/ensureBoot.sh -g
(Actually, it’s been so long since I looked at Boot64 I cannot remember the actual name of the command. Change directory and take a look. The file itself has plenty of comments)
