Many Mac users absolutely face variety of problems related to bluetooth activity in Mac OS X Yosemite or after upgrading to El Capitan. My case was that I got the message of “Bluetooth Not Available”. The others normally get trouble in Bluetooth connection with Apple keyboard, Magic Mouse and other bluetooth devices. Your circumstances might be different. Whatever the issues are, look at the following instruction to get rid of the troubles.

# Solution 1: Delete com.apple.Bluetooth.plist

This method especially fix completely the issue of “Bluetooth Not Available”.

  • From OS X Capitan, access “Go To Folder” by hit “Command+Shift+G” then type the following line: “/Library/Preferences/”
  • Locate the file with extension of “com.apple.Bluetooth.plist” and Delete it. If you see any others with the same extension such as “com.apple.Bluetooth.plist.lock”, delete all of them.

SMC stands for System Management Controller.

  • Shutdown your Mac completely and then remove the battery and the connection to the adapter.
  • You then hold down the Power button for at least 15 seconds, then put in the battery and the adapter. Finally, boot your Mac as normal.

For the Mac which with non-removable battery, you still can reboot the SMC:

  • Shutdown the Mac, then Press Control+Shift+Option + power button together for couple of seconds then free all the keys.

I have done all of this but there are still problems. Especially when I open a program all devices stop working or disconnect. ( MM and Keyboard)
Occurred after I changed my HDD to a SSD, but OS Version is still the same. 10.11.2 (clean install) MBP 2012.

Thank you! I have had no end of problems, erratic behaviour with my Magic Trackpad. Step 1 solved it.

Hi, I have tried all of these settings, but regardless of what I do every time my computer restarts, I have to repair my device. I did not have this issue with my other Macbook Pro. I just bought this device about 1 week ago, which runs El Capital OSX.

#3 worked for me. I have a late 2008 iMac and I’m trying to squeeze the last life out of it. Was driving me crazy when it didn’t detect my Apple Bluetooth keyboard. Thank you!

What about the procedures for an iMac?

Hi everyone, I had this issue and my coworker provided a solution which is a variation from what you see above.

1) Disconnect power adapter
2) turn off your machine
3) hold down CNTRL + SHIFT + OPT + Power for 10 Seconds!!

Good luck. Why doesn’t Apple fix this issue?

MacBook Pro (Retina, 15-inch, Mid 2015)

10.11.6 (15G1108)

Hey kecodoc, thanks so much for your post. Solution #1 solved all my problems I with both trackpad and mouse on iMac 27″ 2013 running OSX Sierra 10.12.3. I had even pulled apart my trackpad to alter the adjustment screw to no avail. Lifesaver mate. Cheers.

This is crazy stuff. I do not even know what “Delete com.apple.Bluetooth.plist” means or where to find a com.apple.Bluetooth.plist thing. “Upgrading” to El Capitan was a big mistake…SO big that it looks like to regain a functional computer I’m going to have to revert to a PC. Which, given how much I’ve spent on Mac hardware, is pretty infuriating.

What happened to “It just works”? When did Apple change its motto to “it just doesn’t work”?

Thanks for the advise. Step #3 solved it. It happened suddenly after latest update for El Capitan. I am getting more and more into NOT updating anything anymore. Never f*** change a running system. This is crucial to Apple products since the launch of OS 10.5 and iOS 8. I will NEVER update to Sierra since El Capitan usually works for me pretty good. Why change that? I don’t know what problems I will run into if I go with Sierra. A wise advise: stick with the OS that came with your hardware. Do not install an OS on top of an OS!
