Many people want to disable the charging chime introduced with the USB-c MBP's (and some enable on non-USB-c). I, however, want to change the chime.
Sadly however I can't change anything in "PowerChime.app" even after disabling the SIP (startup CMD+R, terminal > csrutil disable). I also can't "swap" the PowerChime.app app.
If somebody knows a solution for this, that would be greatly appreciated!
