I'm looking to spice up Mojave a bit by adding colour to menu bar icons. Namely Wi-Fi and Battery icons.
/System/Library/CoreServices/MenuExtras/Battery.menu/Contents/Resources and found the following files:
UPSCharged.pdf - UPSCharging.pdf - UPSEmpty.pdf - UPSLevelBlack.pdf - UPSLevelRed.pdf
Having disabled System Integrity Protection and updated permissions to allow me to edit/replace these files, the menu bar icons remain unchanged.
Is there a way to recompile or alter these running icons once I’ve changed the files I believe have those icons?
