Bluetooth Unavailable in 10.8.4 on 2011 iMac, any solutions?

I did a restart on my iMac today and upon restart I had the squiggly line through the bluetooth icon and no bluetooth in the system preferences. Tried SMC reset, PRAM reset. Nothing works. If it's a hardware issue, can i replace the bluetooth componet myself?

So I solved it by reinstalling Mountain Lion.

Bluetooth/Pairing disconnects wifi/internet. Year 2012 - 2015, any solution?

Hello everyone.
Thanks for reading. If anyone could provide any help would be much appreciated.
Since upgrading to Yosemite OS X, I can't pair any bluetooth devices to my retina macbook pro 2012. I have a mighty mouse and a wire apple keyboard.
Since then, I have not used them. They will connect fine and are able to function fine, but the internet disconnects.
Once I turn off bluetooth, the internet works perfectly. Problem is, I would like to use my mighty mouse and wireless keyboard for work, even a wireless speaker for music.
So, I haven't been able to use my mighty mouse for years. It's 2015 now, and still don't see a solution from all the OS X updates.
If Apple's Customer service or technical support department see's this, please kindly report it to headquarter and make it a priority fix as soon as possible.
It's been 3 years.
Thank you for your time.
Yours sincerely,
Terry

How do I solve iMac "Bluetooth: Unavailable" problem?

I have a 27-inch, Mid 2011 iMac (OS X Lion 10.7.5) which was provided with a wireless keyboard and mouse. Afer a year of use, I started having intermittent problems with the keyboard becoming disconnected, but the problem usually solved itself after a few seconds. Now, I am not able to use the wireless keyboard and mouse at all. I installed new batteries in both the keyboard and mouse, however, it did not solve the problem. The Bluetooth icon at the top right of the monitor reads "Bluetooth: Unavailable" in light gray lettering. I am currently typing this with a wired keyboard and wired mouse. I cannot find any solutions in the Apple Support section. How can this problem be solved?

Try resetting the SMC.

I see them now. I have not encountered those problems in this forum on on my ipads.
I would try to following in this order:
1) Press and Hold the Home and Wake Sleep buttons until the Apple Logo appears.
2) If that doesn't work, try a reset, To reset go to Settings, General, Reset, Reset. (Is this what you did when you mentioned reset?)
3) If neither help, try a restore with itunes/computer. This will reinstall the ipad's software.
If the problems persist, you should contact Apple or take the ipad back to the vendor.
I hope this helps.

HT4528 I have an IPhone 5 and the bluetooth will not stay connected with my 2011 Chrysler 200. I was told by Chrysler service department that it is a problem with the IPhone 5. Is there an update or a fix so i can use the bluetooth in my vehicle?

I have an IPhone 5 and the bluetooth will not stay connected with my 2011 Chrysler 200. I was told by Chrysler service department that it is a problem with the IPhone 5. Is there an update or a fix so i can use the bluetooth in my vehicle?

Iran uses GSM, so the iPhone 5 will work. It is already unlocked. Just put local Iranian SIM in phone.

Setting shows "bluetooth Unavailable" and greyed out

looking for possible reasons, why iphone shows "bluetooth unavailable". sometimes it jumps to "bluetooth off", sometimes to "bluetooth on" and then unsuccessfully searching other devices. iphone is very slow and touch stream reacts with delay.
Any clue, if this is a hardware or software issue? How to fix?
Reset + restore not successful. iOS 4.2.1
Have not recognized the problem under 4.0 - but not sure, if upgrade is the cause of the issue.
Thanks for any hot tip.

IMac Bluetooth unavailable

Hi,
Bluetooth on my 2011 iMac has suddenly stopped working. The squiggly line thru the Blutooth symbol.
I have checked System Preferences and it says 'no information available' under Bluetooth.
I have tried deleting the plist file
I have tried the SMC reset
I have shutdown unplugged everything and unplugged from mains overnight then powered up
I have tried above step but pressed SHIFT/CONTROL/ALT and Power button together before powering up
I seem to have exhausted all the tips I could find and have done a total shutdown and fired up so many times
Is this going to be an expensive trip to my nearest Apple dealer?

Try resetting the SMC.

WIFI & Bluetooth unavailable after upgrading 2.0

Hi,
After upgrading to version 2.0.2 my IPhone has lost WIFI and Bluetooth. Mac addresses appears like 00:00:00:00:00:00 and the option in grey, saying "No Wi-FI" and Bluetooth unavailable.
I tried restoring to a previous version but not luck, looks like something becomes corrupt.
Is there any fix for that?
Thanks in advance.

Try this,
Reset Network Settings
Choose General > Reset and tap Reset Network Settings.
Or do a phone reset
Or return it to apple like this guy on http://gabriel.zeropeople.com/2008/08/15/iphone-wifibluetooth-problems/
Or the scary part

Bluetooth issues, mid-2011 iMac running Yosemite?

My bluetooth connection has "static" when streaming from my iMac. I never had this issue before Yosemite, the disturbance seems to be like a hiccup every couple seconds. It doesn't do it when I stream from another source, just the iMac. It seems to do this with any bluetooth source too, not just the main speaker I noticed it on.

Strange.....here's an Apple article that mentions a few other possible sources of interference Wi-Fi and Bluetooth: Potential sources of wireless interference - Apple Support
And OS X: Bluetooth devices become unresponsive - Apple Support

My 2011 Imac 27" has been crashing and running very erratically and slowly. The only change has been the update to 10.8.1, I will paste the consol kernal panic report. Is there a software conflict?

Hi, first time posting on the forum. I own a 2011 IMAC i5 with 12gb of ram 27 inch. Over the last five days the computer has been crashing and running very erratically. When the computer has crashed the entire computer has become unresponsive and frozen, requiring a reboot or two. At other times the computer has slowed way down and the dreaded spinning beachball has appeared and the computer takes its sweet time trying to process something. Iphoto has also crashed independently when the beahball will not disappear. THE entire system is running way below its usual stellar quad performance. I have run a ram test and everything has come back clean, I have fixed any broken permissions, and deleted any newly added software (starcraft2). There is over 250Gb of hard drive free and the activity monitor shows no unusual processes. The computer automatically updated it self recently to 10.8.1 has this caused a conflict with some software? Or is there a deeper problem?
Below are the console reports. There are also reports for unversalaccessd , mdworker, Isregister, loginwindow, iphoto, DMproxy which can be supplied.
Thanks for any help.

My 2011 IMac will not boot up past the White apple logo screen with the whirly circle

My 2011 IMac will not boot up past the White apple logo screen with the whirly circle. I have tried various commands but to no avail. does anybody have any advice?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

There aren’t any. AirDrop between the platforms requires that the Mac support Bluetooth 4.0, which wasn’t introduced to them until the 2012 models.

If I am using a 2011 iMac and 2010 macbook will handoff work with my iPhone 6

Ian using a 2011 iMac does handoff work with this computer?

Sorry, no and don't even try using the Bluetooth Dongle approach as Apple does not support this either. You need new hardware for Handoff to work unless it is around 12 to 18 months old at the latest.

Bluetooth Unavailable in 10.8.4 on 2011 iMac, any solutions?
