Q: reinstalling os x, bluetooth disconnects, El Capitan

Hi everyone,

I have started to be plagued by random bluetooth mouse (and kb & trackpad if connected) disconnects/reconnects following the 10.11.6 update on my iMac Retina 5K late 2015. Nothing has changed in my set up and my investigations into hardware failures seem to point to a software not hardware issue.

I have tried everything advised in the forums by many people, and seem to be left with no alternative but to wipe my system and reinstall a fresh operating system, and then restore my apps and documents etc.

My question is, if I am to follow this procedure, do I need to sign out of icloud first? I am not selling it, just wanting to perform a clean install, then restore back my apps etc.

I have read many entries for other users on the Net reporting similar Bluetooth issues, and supposedly Apple put a fix in 10.11.6 to fix random dropouts, so there must be a recognised problem.

I regularly use TechTool Pro (a favourite of the Apple genius's) and the Bluetooth module checks out fine, as does the rest of the system.

I would welcome advice from anyone before I take the drastic move of the clean install, and also like to hear from anyone experiencing similar bluetooth disconnect issues since El Capitan updates.

Thanks

Craig

OS X El Capitan (10.11.6)

    Hi,

     

    No, no need to sign out of iCloud prior to restoring to factory settings.

     

    As long as you have a backup to restore your data from it's not really drastic.

     

    Before you do that, since you think this might be a software rather than hardware issue, it may be corrupted Bluetooth preferences.

     

     

    Open a Finder window. From the Finder menu bar click Go > Go to Folder

     

    Then type or copy paste the following:

     

    /Library/Preferences/com.apple.Bluetooth.plist

     

    Click Go then move the com.apple.Bluetooth.plist file to the Trash.

     

     

    See if that makes a difference.

     

    If not, follow the instructions for restoring OS X and restoring from a backup > OS X Recovery
