Bluetooth not available after update to 10.9.2

Question

Bluetooth not available after update to 10.9.2

Installed the 10.9.2 update and now I have no Bluetooth.

Task bar icoshows the zig-zag line and text is 'Bluetooth : Not available' . No Bluetooth System Preference option either.

I have tried:

Deleting /Library/Preferences/com.apple.Bluetooth.plist and restarting
Repaiting Disk Permissions
NVRAM reset (Option+CTRL+P+R at startup)

None of these fixes the problem.

Getting very annoyed now.

Can anyone suggest anything else?

Mac mini, OS X Mavericks (10.9.2)

Does the Bluetooth preference pane show up in System Preferences? If not it means your Mac mini is not "seeing" the Bluetooth transceiver. Since this apparently correspoinds with the installation of OS X 10.9.2 I would suggest you download the OS X Mavericks 10.9.2 Update (Combo)and install it. Combo updtes are a standard "fix" when strange ethings happen after a regular OS update.

Installing the combo update on my MacBook Air allowed Bluetooth adapter to be detected again. h/t to Joe Bailey.

Neither resetting NVRam nor following the article linked by Linc Davis had previously helped.

I thought I had done this but in fact I hadn't followed it to the letter. I had reconnected the USB devices before restarting!

Tried again. Shutdown, disconnected all USB cables, (I disconnected power too), waited 2 minutes, started up with USB still disconnected. Bluetooth now works!

Reconected USBs - all ok.

Just shows. Make sure you read the instructions properly.

Thanks.

Thanks for the suggestion.

There was no Bluetooth preference pane and System Report showed no Bluetooth device (No information).

I did try the combo update but it didn't work for me.

As per my other reply, the standard support instruction in the item provided by Linc fixed it for me when I (finally) followed them correctly.

I followed the instructions exactly twice, but it did not solve my problem.

I did the OS combo update but still nothing. Then I turned off the computer for 2 minutes with all USB devices disconnected. Still no good. Finally had to have the computer forget the mouse then pair it again. Now it's working fine.
