Turn off Flavours
The preferable way for turning off Flavours is to launch Flavours.app and turn off the toggle switch on the top of the main window. This will shut off Flavours and restore all system files from backup.
From Single User Mode
If - for some reason - you are unable to turn off Flavours from within the application, you can use the restoreui utility (bundled with Flavours). The restoreui utility can be launched from Terminal or from Single User Mode (boot without UI) by typing "restoreui" at the command line prompt.
When running in Single User Mode (booting your mac with CMD-S pressed) the disk is mounted read-only. OS X requires a system check before mounting the disk as readwrite (trying to execute restoreui on a disk in read-only mode will output a "Segmentation Fault:11" error). Type the following commands, in order:
/sbin/fsck -fy /sbin/mount -uw / restoreui
The recommended way to completely uninstall Flavours from your system, is to launch Flavours and access the menu "Flavours > Uninstall Flavours...".
If you are unable to uninstall Flavours as recommended, or if your system is still partially themed after uninstalling and restarting your Mac (usually happens when attempting to uninstall Flavours using a 3rd party installer), you can use Troubleshooter taking these steps:
1. Download the Troubleshooter.app.
2. Launch the downloaded application, select "Restore Aqua UI from online backup", "Uninstall Flavours", "Remove all related data" (optional) and click "Go!"
3. Restart your Mac
As an alternative, if you ran into a different, odd problem, you can also try to boot into Safe Mode mode once, and then restart normally. Booting into safe mode has been concisely reported as an effective way of fixing cache issues, startup issues and other odd behaviors. You can read more about it here.
