Note for Big Sur, Monterey and Ventura users: If you want to edit system .car files it is no longer enough to remount the boot volume as read/write. You will need to follow the steps below:
- Disable SIP and authenticated-root: In recovery mode, open Terminal and enter
csrutil disable
csrutil authenticated-root disable
Then reboot into macOS.
- Identify the System Volume Disk Device Name
Run the mount command in Terminal to identify the devices of your system volume snapshot. Look for the device mounted at “/“, which identifies the system volume disk. In the following example, this disk is
/dev/disk4s5s1.
/dev/disk4s5s1 on / (apfs, sealed, local, read-only, journaled)
devfs on /dev (devfs, local, nobrowse)
/dev/disk4s4 on /System/Volumes/VM (apfs, local, noexec, journaled, noatime, nobrowse)
/dev/disk4s2 on /System/Volumes/Preboot (apfs, local, journaled, nobrowse)
/dev/disk4s1 on /System/Volumes/Data (apfs, local, journaled, nobrowse)
To get the actual name of the system volume disk, remove the final “sX” from the device. In the preceding example, the name of the system volume disk is /dev/disk4s5.
- Mount a Live Version of the System Volume Run the mount command in Terminal to mount the system volume disk to a temporary location. When running the mount command, always include the nobrowse mount option to prevent Spotlight from indexing the volume.
mkdir /Users/<YOUR USER NAME>/livemount
sudo mount -o nobrowse -t apfs /dev/disk4s5 /Users/<YOUR USER NAME>/livemount
cd ~/Downloads/AquaLickX-main/sudo cp Aqua.car ~/livemount/System/Library/CoreServices/SystemAppearance.bundle/Contents/Resources/sudo cp VibrantLight.car ~/livemount/System/Library/CoreServices/SystemAppearance.bundle/Contents/Resources/sudo cp DarkAqua.car ~/livemount/System/Library/CoreServices/SystemAppearance.bundle/Contents/Resources/sudo cp VibrantDark.car ~/livemount/System/Library/CoreServices/SystemAppearance.bundle/Contents/Resources/- Bless your livemount directory with
sudo bless --mount /Users/<YOUR USER NAME>/livemount --bootefi --create-snapshot
If you're on an Apple Silicon Mac then issue this bless command instead
sudo bless --mount "$HOME/livemount/System/Library/CoreServices/" --setBoot --create-snapshot
Reboot your Mac using the regular reboot mechanisms immediately after issuing the bless command described above.
the command below will reboot your Mac then and there, so be careful unless you're certain that you have all your work saved in other applications
type sudo reboot in the existing Terminal window
