IMac 5,2 Core2Duo lost Bluetooth - Fixed

This may apply to all Macs, but I have only one iMac that has lost Bluetooth so it was only tried out with that.
Our older white iMac 5,2 lost Bluetooth one day - no warning, no reason, it was just gone. I read the forums and tried everything, resetting SMC or what ever, re-installed the original Mac OS that came with the iMac, nothing made any difference.
I took a punt on a £2 Bluetooth USB dongle from Amazon, what do you know it actually works! It is seen by the iMac as if it was the original Bluetooth hardware, uses the built-in drivers. I don't know at this stage how well it's going to work over the coming weeks or months, but it's looking good as it will only be used for Apple keyboard and mouse (from the same period), and they paired without any problems.
The actual name of the item on Amazon was Super Mini USB Bluetooth 2.0 Wireless Adapter Dongle - OEM, I'm sure a simple search would find it.
For all those losing Bluetooth, after having tried the suggestions in these forums with no luck I would say give this a try. I plugged the dongle directly into the back of the iMac, this is not a problem for us however as it effectively replaces the wired USB connection that the original keyboard used.

And to add more information to my prior post, Airport is also nonfunctional after the 10.5.2 upgrade. Unlike the bluetooth problem, System Profiler sees the Airport card, but trying to configure the Airport under Network fails. The button to turn the Airport on is greyed out, and I haven't found another way to turn it on. I've tried resetting PRAM and SMC, rebooting, creating another user account. I've also re-installed 10.5.0 (archive/install), and that brings back both Bluetooth and Airport operation. When I then apply the 10.5.2 combo updater, the OS can no longer find the BT hardware module, and the Airport card can't be turned on. Rebooting under Tiger fixes it all, so I think I'm safe in saying it's the 10.5.2 update that's breaking things.

I need to reinstall the system software on my older iMac. I have lost the system disks, though... so now what? It had 10.4.

I need to reinstall the system software on my older iMac. I have lost the system disks, though... so now what? It had 10.4. We moved, and I have looked everywhere. Am I doomed to find a way to buy it? Can taking it into the Apple Store fix it? Will it be expensive THERE? I've already saved all of the files I want off of it.... I just need it to work now.

You've lost me on why you need to reinstall Tiger, when you already have all the files you wanted (which means Tiger worked perfectly fine). If you want to upgrade to Leopard, that's a different issue: your Mac needs to meet the minimum system requirements for that, which you can easily determine.
If you just want to get a replacement set of Tiger install discs, you can try calling AppleCare and see if they're able to send you a replacement set, and if not, you'll have to buy a new set yourself. You can get them on eBay, Craigslist, and HardCore Mac (http://store.yahoo.com/hardcoremac/), although they sell it for ridiculous prices.

My Itunes says there is a corrupt file and will not open (IMac 2010). I couldn't fix it by reinstalling ITunes so I moved ITunes to trash. It will not delete from my trash as it is saying "Japanese.lproj" is in use. I have never opened or used "Japanese.lproj". I can't delete ITunes or open ITunes to close the Japanese.lproj, what do I do? Thank you for any help you can provide..

Interesting. This sort of thing is more common on Windows systems. Taken at face value, one of the iTunes program files (one of the Japanese language resources) is damaged.
I'd try running your Disk Utility over your startup disk. Does it find/repair any damage? If so can you empty your trash and reinstall your iTunes successfully now?

My iphone freezes up frequently and i have to connect to Imac to restart. Any easire fixes?

My Iphone frequently freezes up, especially after a download. To get it working I need to connect to Imac. Any easier way to fix or avoid?

Basic troubleshooting steps clearly outlined in the User Guide are restart, reset, restore from backup, restore as new device.
Have you tried ALL the troubleshooting steps? If you have and you're still having problems, then you'll need to bring your phone into Apple for evaluation and possible exchange.

I cannot open mail attachments on my iPhone 4S. I have reset it 3 times and lost Bluetooth once, but at least it's back on.

I cannot open mail attachments on my iPhone 4S. I have reset 3 times and actually lost Bluetooth once, but at least that's back on now.

Try to set it up as new device, explained here:
How to back up your data and set up as a new device
First without using the backup, in case it contains corrupt data.
If it works after that, use the backup to restore from.

Lost Bluetooth

My iphone 4S has suddenly lost Bluetooth! It no longer appears on the menu when I go into Settings and I can't get it from the pull up screen although it still has a button, it simply says "Bluetooth not available". Not sure if the recent upgrade is involved but ir is very frustrating as I just bought the BOSE wireless Bluetooth speaker and I can't use it! Anyone come accross this or have any ideas what has happened?

Hi Grandad SE,
If you are having issues with Bluetooth no longer being available, you may find the troubleshooting in the following article helpful (it is for a similar WiFi issue, but the steps should be the same):
iOS: Wi-Fi settings grayed out or dim

Lost bluetooth on my toshiba

I have lost bluetooth in my machine and would like some1 to help me troubleshoot this.
Solved!
Go to Solution.

According the specs here, your computer does not come with the Bluetooth hardware built in.
It's confusing because Toshiba includes the Bluetooth software.

Lost Bluetooth iphone 4

I lost bluetooth. When I go to "Settings" under "General" Bluetooth shows OFF. When you click on Bluetooth it doesn't give an "on/off" option just the spinning wheel of death. I have turned it completely off, I have reset network settings and I have turned off and on airplane mode...I finally connected it to Itunes and downloaded the latest software version 4.0.2 and then restored everything. It doesn't even show a Bluetooth Icon in the top right corner of the screen. Any other suggestions?

Update... I also lost WiFi a couple of days later. I took the phone to Apple store and they did a "restore" and still nothing. They said it's a hardware issue and replaced the phone.

My iMac lost Bluetooth connections for keyboard an d keypad how can I reset it?

First the keypad list it's Bluetooth connection then when I used the Bluetooth assistant it lost the keyboard . How can I re establish connections? Batteries are good.

If you connect the iPod to the computer (with the iTunes library) that was previously used to sync the iPod, it should unlock. If that's not possible, you should be able to connect the iPod to the current computer, and use the current iTunes library to Restore the iPod. The Restore button is on the iPod's Summary screen in iTunes. This will erase the iPod and give it a fresh start.

Lost Bluetooth connection with iPhone, now not possible with Yosemite! iPhone 5c with 8.1. Any fix ideas?

MacBook Pro, late 2011 version. Upgrade to Yosemite seemed to go well, UNTIL! Yosemite & my iPhone 5c with 8.1 refuse to pair and connect. iPhone says MacBook Pro does not support Bluetooth! Any ideas?

An iPhone will not pair via Bluetooth to a computer (Mac or Windows) except for personal hotspot and then only if your cellular plan supports it. https://discussions.apple.com/docs/DOC-7722
If you are attempting to use Handoff/Continuity, that does involve Bluetooth but the devices are NOT paired; Bluetooth just needs to be on and the devices in range of each other. The following may help with Handoff/Continuity issues: http://support.apple.com/kb/TS5458

Yosemite issues iPhoto images lost, bluetooth not syncing

I uploaded Yosemite and then was instructed that iPhoto needed to be upgraded. Did that and lost 50% of my albums. Also
bluetooth is not syncing now and is breaking up. At the shop where I took the MacBook Pro, on returning, service person
said many reporting the same issues. Please advise

No I do have a back up Its kinda long to explain but last a little over a week ago, i delete a important file in my private/var folder and screwed up my computer. Worst part was I didn't run time machine for almost a month that way all my pics that I did bring on weren't backup up. i know this sounds careless but normally does happen like this. Anyway I had to take my imac into to get it fixed and the only way to do it without losing all my data was to do an archive and install and of course my drive was full so they had to swap it out and they put in a 2 TB and ya, so now I am where I am at. Everything is here but got pro app and iphoto issues. I guess worst case scenario if something does go wrong on the install I kinda do have a back up as the old drive can be put into a enclosure and used as a HD but I guess it is a bootable drive so I don't know if it would mount properly. Thanks for you help though/ Really Appreciate it.

Lost Bluetooth on mac Wireless Keyboard

Wierd issue
Since the last update I lost the ability to connect my mac wireless keyboaed
On my Imac and MBP. They see it but will not pair.
Now I can pair this keyboard on my iPhone and my iPad
I reset the PRAM and tried all the suggestions on the countless threads that are up for this issue.
The only reason I started my own thread was do to the fact that my mobile devices will pair and maybe I have a different issue.
One more thing. I used to have a bluetooth icon in my tray at the tp and in the system prefs. Now I have to go to etwork connections to access it.
I'm pretty sure it happened on the last update
MacBook Pro, Mac OS X (10.7.5), 2.44 GHz Intel Core 2 Duo 4 GB ram
iMac, Mac OS X (10.7.5), 2.66GHz Intel Core 2 Duo 4 GB ram
Will these two computers work well with MT Lion
Thanks

Try fresh batteries but I suspect a hardware problem with your KB.
You can then try cleaning it. Nothing to lose:

My 3gs disconnects from my wi-fi at night while plugged into my wall charger causing my AT&T data usage to go over my 200mb plan. I like to listen to a radio app overnight and this situation is quite annoying. AT&T forgave the overage but had NO solution to my paltry wi-fi delimma. I am going to try the "sync while connected to wi-fi" setting in I-Tunes but I am almost afraid to try it again because the overage may not be forgiven this time and It's not worth the hassle. I have been using my Macbook instead for this duty with no worries of an overage. I'm also a Pandora fan and this has limited me to just using my I-Tunes library for music instead of Pandora. This is a problem that benefits AT&T and I'm sure they bill for LOTS of overages because of this problem. I hope the I-Tunes solution will FIX this glitch.

My brand new iMac keeps freezing, how can I fix this?

I have only had my iMac for about a month and it freezes all the time. I can move the mouse but can't click on a thing. Does anyone know any possible solutions?

I have had this happen to me twice in the past week. Right now is the 2nd time. I can't click on anything on my computer. I have tried with my Wacom tablet and even plugged in a mouse ( my normal one is bluetooth). The last time the only thing that worked was rebooting with the startup dics and running utilities, but it has only been a week and it has happened again. The catch is that the first time it happened I was running Snow Leopard, but I upgraded to Lion several days ago. What the heck is going on with my iMac and how can i fix it? Can I still use the startup disc that came with the computer even though I now have Lion?

Constantly resetting SMU for lost Bluetooth/Memory errors

We are constantly losing bluetooth and randomly experiencing other behaviors that are usually helped by resetting the SMU. But we're now resetting the SMU nearly every other day. It fixes everything for a short while, and then, early the next morning at wake-up or re-boot, there is no bluetooth. And, along with that, uncharacteristic fan running on an otherwise very quiet machine.
Perhaps related?: An Apple Hardware test shows an error in the second RAM slot. I removed that stick (we have two identical 500mb Crucial sticks) and the test came up fine. Then switching the sticks and the error is still in the second slot, so I'm thinking there is something wrong with the slot, not the RAM sticks.
Any suggestions before we trek to the Mac Store for help?
iMac G5 1.8 GhZ Mac OS X (10.3.9)

Thanks, I think we'll have to do that. I removed the memory stick from the second slot, after actually switching the sticks, and this morning the little bluetooth mouse woke up the computer just fine. So the slot itself is very likely the problem. Still under Apple Care, so I hope it will be covered!
