Got a new iMac but the wireless trackpad and keyboard aren't working.

I should add: I don’t have a wired mouse or keyboard.

I suspect the issue happened during the migration. According to some sources the mouse keys function can be activated when using Migration Assistant which leaves the keyboard unresponsive.

Here is a fix according Cnet

1. Open System Preferences and click on the Universal Access preference pane.
2. Click the Mouse & Trackpad settings tab.
3. Click the “Off” radio button next to Mouse Keys.
Note: You may also check/uncheck the box for “Press Option key five times to turn Mouse Keys on or off”.
Note: If you are logged on to a user where Mouse Keys is already disabled, but your keyboard is not responding properly, toggle the radio buttons for Mouse Keys “On” then “Off” to restore normal functionality.*

More Information:

When Mouse Keys is enabled with one of these keyboards, you can use the keys 7,8,9, U, I, O, J, K, L, M, and ’.’ (period) to control movement of the mouse pointer and mouse clicking, but other numbers, letters, and keys cannot be used. The following keys will continue to operate normally when Mouse Keys is enabled: Esc, Function keys, Eject, Delete, Tab, Shift, fn, Control, Option, Command, and the arrow keys.

If you would like to control the mouse pointer with the keyboard and also use the keyboard for typing, enable “Press the Option key five times to turn Mouse Keys on or off” in Universal Access preferences. Then, press the Option key five times each time you want to switch between controlling the mouse pointer and typing.”

I hope this helps! Congrats on your iMac!

I can’t do any of those things on my iMac since the keyboard and trackpad don’t work.

The mentioned navigation keys are not working?

I have also read a hard reboot, wait a full minute then restart can get them recognized. Have you rebooted?

This Apple support document offers suggestions also.

The keyboard doesn’t work at all.

I’ll try that.

Tried restarting, and it doesn’t seem to have much effect — though, oddly, I can control the volume with the keyboard.

The trackpad is working! :)

WONDERFUL! Progress!

Check the mouse suggestion now!

I got the keyboard and trackpad to work by turning the computer off with the power button, then turning it back on. After the startup, it automatically searched for the devices.

Thanks for the suggestion, Dog!

The migration doesn’t seem to have worked, but whatever.

I am so glad it worked!

Migration Assistant is in Applications <- Utilities. You can try running it again.

I also hate Migration Assistant.

If you don’t have a external drive I will just toss out the idea of FireWire target disk mode. If both Macs have FireWire It will see the other one as a drive so you can just drag stuff over.

You can try running it again.

I seem to be stuck in a vicious circle where migrating causes the keyboard and trackpad to stop working, and to get them to work again, I need to restart, which undoes the migration.
