All things considered, Bluetooth is out and out advantageous, both for devices that are constantly associated with your Mac, and those you just use sporadically. Be that as it may, Bluetooth network can likewise cause haul your-hair-out kinds of issues when things quit functioning true to form.
Bluetooth Connection Issues
Most of the problems occur when a Bluetooth device that is paired with a Mac simply stops working. It may be listed as connected, or it may not show up in the list of Bluetooth devices at all; either way, the device no longer seems to work.
Many of you have tried turning the Bluetooth device off and then back on, and even though it may seem a bit silly, that’s a very good place to start. But you need to take an additional step, and try turning your Mac’s Bluetooth system off and then back on.
Turn It Off and Back On

So much for the easy solution, but it doesn’t hurt to give it a try before moving on.
Repairing Bluetooth Devices
The greater part of you have had a go at fixing your Mac with the gadget or endeavored to disassociate your Mac from the gadget. In either case, nothing changes and the two just won’t coordinate.
Some of you have referenced that the issue begun when you redesigned OS X, or when you changed out batteries in the fringe. What’s more, for some of you, it simply occurred, for no evident reason.
A Possible Solution to Bluetooth Problems
Various things can cause Bluetooth issues, however the one we’re going to deliver here is explicit to two normal availability issues experienced by numerous clients:
Bluetooth devices that never appear to have the option to combine with your Mac.
Bluetooth peripherals that were matched effectively, yet have quit working (they may even now appear in your rundown of combined devices).
In the two cases, the reason is probably going to be defilement of the inclination rundown utilized by your Mac to store Bluetooth devices and the present condition of these devices (associated, not associated, effectively combined, not matched, and so on.). The defilement keeps your Mac from refreshing the information inside the record, or from appropriately perusing information from the document, both of which can prompt the issues depicted previously.
Fortunately, the fix is a simple one: erase the awful inclination list. In any case, before you begin messing around with inclination documents, ensure you have a present reinforcement of your information.
How to Remove Your Mac’s Bluetooth Preference List
Open a Finder window and navigate to /YourStartupDrive/Library/Preferences. You can press Command-Shift-G on your keyboard and type or paste /Library/Preferences into the resulting field. Hit the Enter key to go there directly.
For most you, this will be /Macintosh HD/Library/Preferences. If you changed the name of your startup drive, then the first part of the pathname above will be that name; for example, Casey/Library/Preferences.
You can also access this with /Library/Preferences, as the first slash implies the startup drive on a Macintosh.
You may notice the Library folder is part of the path; you may also have heard that the Library folder is hidden. That’s true of the user Library folder, but the root drive’s Library folder has never been hidden, so you can access it without performing any special incantations.
Once you have the /YourStartupDrive/Library/Preferences folder open in the Finder, scroll through the listings until you find the file called com.apple.Bluetooth.plist. This is your Bluetooth preference list and the file that has probably been causing the problems with your Bluetooth peripherals.
Select the com.apple.Bluetooth.plist file and drag it to the desktop. This will create a copy of the existing file on your desktop; we’re doing this to ensure that we have a backup of the file we’re about to delete.
In the Finder window that is open to the /YourStartupDrive/Library/Preferences folder, right-click the com.apple.Bluetooth.plist file and select Move to Trash from the pop-up menu.
You’ll be asked for an administrator password to move the file to the trash. Enter the password and click OK.
Close any applications you have open.
Restart your Mac.
Pair Your Bluetooth Devices With Your Mac
When your Mac restarts, another Bluetooth inclination document will be made. Since it’s another inclination record, you’ll have to combine your Bluetooth peripherals with your Mac once more. More then likely, the Bluetooth right hand will start up individually and walk you through the procedure. However, on the off chance that it doesn’t, you can begin the procedure physically by doing the accompanying:
Make sure your Bluetooth peripheral has fresh batteries installed, and the device is turned on.
Launch System Preferences by either selecting System Preferences from the Apple menu, or by clicking on its Dock icon.
Select the Bluetooth preference pane.
Your Bluetooth devices should be listed, with a Pair button next to each unpaired device. Click the Pair button to associate a device with your Mac.
Repeat the pairing process for each Bluetooth device that needs to be associated with your Mac.
What About the Backup of the com.apple.Bluetooth.plist File?
Utilize your Mac for a few days (or more). When you’re certain that your Bluetooth issue has been settled, you can erase the reinforcement duplicate of com.apple.Bluetooth.plist from your work area.
Should the issues proceed, you can reestablish the reinforcement duplicate of com.apple.Bluetooth.plist by essentially replicating it from the work area to the/YourStartupDrive/Library/Preferences envelope.
Reset the Mac’s Bluetooth System
This last proposal is a final desperate attempt to get the Bluetooth framework working once more. We don’t suggest utilizing this alternative except if you’ve attempted the various choices first. The purpose behind the wavering is on the grounds that it will make your Mac disregard the majority of the Bluetooth devices you have ever utilized, driving you to reconfigure every single one.
This is a two-advance procedure that uses a marginally shrouded highlight of the Mac’s Bluetooth inclination sheet.
To start with, you have to empower the Bluetooth menu thing. In case you don’t know how to do this, see the Turn It Off and Back On area, above.
Presently with the Bluetooth menu accessible, we’ll begin the reset procedure by first expelling all devices from your Mac’s table of known Bluetooth devices.
Hold down the Shift and Option keys, and then click the Bluetooth menu item.
Once the menu is displayed, you can release the Shift and Option keys.
The drop-down menu will be different, now showing a few hidden items.
Select Debug, Remove all devices.

Hold down the Shift and Option keys once again, and click on the Bluetooth menu.
Select Debug, Reset the Bluetooth Module.
Your Mac’s Bluetooth system has now been reset to a condition similar to the first day you powered on your Mac.
