Chosen Solution
I am (not a Mac expert) trying to repair the Macbook of a friend, whose keyboard has stopped working after an upgrade to 10.9.2. It is an icelandic keyboard and right now types only three characters and all others either do not respond or come as blank spaces. An external bluetooth keyboard and a usb keyboard work fine. Tried to reset (through the usb keyboard) PVRAM but it keeps going into the Mac utilities, safe mode option is also not working. Could not reset SMC with the Shift-Control-Option keys (on the left side) and the power button… so opened the back panel and disconnected the battery connector and pressed the power. When I go into Mac Utilities (where I reached instead of PVRAM reset) there is a log for which I have not found any clue on the internet ‘‘‘Apr 1 05:30:40 localhost Language Chooser[359]: Waiting for prepaired devices to appear Apr 1 05:30:44 localhost configd[114]: subnet_route_if_index: can’t get interface name Apr 1 05:30:53 localhost Language Chooser[359]: Prepaired wait done.

Thank you
FINALLY I FOUND A SOLUTION… Posting this as a help for someone who might be stuck in the same situation… Somehow my keyboard mapping has got corrupted and since I could not find a direct way to edit the keymapping for Mac I used a superb software called KeyRemap4MacBook and it has remapped my key settings, over-riding the defaults in my Macbook and now I can happily work on my macbook. It seems that somehow there is a hardware error and my Left Shift key is not working but all the rest now work properly…
It sounds like there is a bug with the update. I don’t use a mac, so I would be guessing if you can reinstall the prior version of the software. But if it is possible, downgrade the os and see if that resolves the issue.
Malware. Yes there’s tons of it for Mac. Check the National Institute of Standards for Technology National Vunerability Database of Common Vulnerabilities and Exposures, almost 9,000 for Apple as of Feb. 2018. About 1/10 as many as Windows but uh would you go out in a thunderstorm if you knew you had a 1/10 chance of getting struck my lightening? These and similar messages from an “unknown” process have been popping up in logs (Cmd+L) during installs in Recovery and elsewhere for a while now: Unknown[528]: Keyboard Layouts: keyboard layout identifier -14934 has been replaced with -28673. Either Apple is totally off their game or its malware. Guess its true about what goes up…Too bad. They’re totally screwing themselves over by not confronting these problems and just living in denial and refusing to help their paying customers.
