If the Boot Logo image dimension is too big for your Monitor’s screen resolution, you might just end up with a black screen during the BIOS initialization at boot. To exchange the default original Boot Logo image file stored in “Raw Section” by the iMacPro.raw image file that you previously downloaded to your Desktop, right-click on “Raw section”, select this time “Replace body” and select the iMacPro.raw image file on your Desktop.

After successfully implementing BREW and QT5, we can now download the most actual CodeRush UEFIPatch distribution from Github to our home directory with the following terminal command: git clone bashī.) Now enter the following “bash” terminal command and follow the standard BREW installation instructions: /usr/bin/ruby -e "$(curl -fsSL )"Ģ.)

But I found this guide and applied it to new boot screen image. Since this logo’s resolution is so small, it looks stretched and ugly in my 4k and 5k resolution monitors. If you use a different brand of board, you can change the logo through a custom BIOS created using UEFI Tool. Gigabyte users can easily change using the apps provided by Gigabyte.
In this guide, we will change the motherboard’s brand logo on the first boot screen to the image of a custom iMac Pro.
