- Bluetooth Not Available? 6 answers
Firstly I would like to say that I have never used a Mac in my life before today so apologies if i am a little slow on the uptake. I recently purchased the iMac (27-inch, Mid 2011) which i believe is running a Yosemite v10.10 OS.
The iMac was second hand and there was no install discs in the box. It did come with the Apple mouse and keyboard, however i cannot pair them with the Mac as the Bluetooth won't turn on ('Turn Bluetooth On' button is greyed out in System Preferences>Network>Set Up Bluetooth Device...). The Bluetooth icon in the top left is also greyed out with a line through it and says 'Bluetooth: Not Available' on it.
So far i have Deep Breath:
- Checked the technical specs to ensure this model has Bluetooth.
- Repaired Disk Permissions in Applicatiopns>Utilities>Disk Utilities + Restarted.
- Deleted 'com.apple.Bluetooth.plist' in Library>Preferences + Restarted
- Reset the SMC + Restarted
- Completed a PRAM reset + Rebooted
- Installed the 'Bluetooth Switch' widget (Which appears to do nothing)
- Some people have suggested that if you shut down and log in a few times it eventually sorts itself out, well i have done that about 10 times now and it has definitely not fixed itself.
... and none of it has made a single bit of difference.
Not such a good start so far from Apple, I am starting to wonder why i switched from PC's. Can anyone help to restore my faith?
