Exchanged keyboard from UK layout to German (hardware)
MacBook Pro 15" Retina A1398
Does changing UK keyboard for German one require me to update or flash some kind of firmware or update software?
I have replaced keyboard from UK to German and now I have information that something is draining too much power and the USB has to be disabled.
El Captain is giving me kernel crash pointing towards USB xhci and not booting,
Updating to High Sierra gives me sleep/wakeup failure pointing towards USB and two dead USB ports (but SD card reader and HDMI working just fine) and info about drawing too much power, downgrading to Mountain Lion makes one of USB (left side) working but I think as USB 2.0 and second one dead but no sleep/wake problems whatsoever, and upgrading to Yosemite leaves computer with same problem as in Mountain Lion. But beside working good with one USB port.
I'm not sure if changing keyboard to different language should be made with some software servicing?
Sorry I have forgot to add that I have also done SMC and NVRAM resets and hardware test showing all good.
