Keyboard and mouse not working after update.

What do I have to do to get them working again? I've tried powering off and on by holding the button on the back but still nothing.
[doublepost=1458595094][/doublepost]Weird I plugged them in and they work, Bluetooth won't turn on :/ just greyed out.
[doublepost=1458595792][/doublepost]Hmm my internet is slow and the bass has gone from my Speaker :/ Which is odd because I have optical out to a Naim Mu-So and the audio is tinny after the update.

How do I roll back this is ****?
[doublepost=1458596017][/doublepost]My Wifi is so slow as well.

I tried Command Option P and R but it hasn't fixed it :/

I'm never updating again.

Me too on my 5k iMac. Keyboard & mouse not working, though the (wired) keyboard came back after a reboot.

After an hour or so of fiddling with various things to try & get Bluetooth & the mouse working, I finally uninstalled iStat menus - figuring it was the only non App store software I had, and it installs its own drivers etc. Bluetooth came back shortly afterwards, and is now working fine. Of course it might have been coincidence. It was a pain to uninstall it with no mouse - but I got there in the end.

Have you got any non App store software installed? Particularly software that needs to install drivers etc?
