Bluetooth is not recognized after install of Mountain Lion, trackpad works for curser movement, however swiping and scrolling has been disabled. Turned machine off and restarted, had a clean install. Is there a solution?
iMac, OS X Mountain Lion
Hi..
Did you check the settings for trackpad in system preferences ?
Works fine on both my Air and iMac.

I have exactly the same problem. No apparent bluetooth hardware, keyboard doesn't work, trackpad does work for tracking. So bluetooth is partially active but definitely broken. I have an iMac 11.1. Help!
Yes, I have check all of the preference setting and that is a piece of the problem; there isn't a bluetooth preference any longer.
Did you try these steps? They worked for me and a couple other people:
1 - Turn on automatic login: System Preferences > Security & Privacy > General > Click the lock to make changes > If Disable automatic login is checked, uncheck it > Pick your user account and password > Ok.
2 - Shut down your computer.
3 - Turn off your keyboard and mouse: For keyboard and wireless trackpad you hold the power button until the light goes off.
4 - Start your computer.
5 - Once your desktop has fully loaded turn the keyboard and mouse back on, everything should work.
Thanks for the reply. I have tried this sequence without success. Here is what is confusing. I am a bootcamp user and Windows works just fine. I was using Lion and it worked just fine. Now with Mountain Lion, it will not work in either OS X or the restore for OS X. It's almost like I have an unsupported chipset.
Other suggestions are welcome, I'd really like to fix this.
I had the same issue. I shutdown my system and left it off for 2-3 minutes and then powered it back on and Bluetooth came back. Hope this helps your issue also.
I'm working now but not exactly sure why. I would advise trying the solutions from joe81tx and contton66 above first.
I think that leaving the machine off and unplugged for several minutes (I had been doing about 30 seconds) was important. When this was done, I was able to pair properly in a boot from the restore partition which I could not do before. After doing this, both the trackpad and keyboard came up in Mountain Lion although bluetooth still didn't show in System Preferences and the keyboard function keys did not work (try volume) and the trackpad only had cursor movement without gestures. At this point, I reinstalled Lion and everything is now okay. That said, I think that contton66's suggestion to turn the machine off for an exended period of time was important.
