I have a new MacBook Pro with Mountain Lion, delivered mid July 2012.  It has recently developed an annoying habit of keeping trying to connect to the hard disc of one of my other, older Macs, even when not using or wanting to use that disc.  Periodically, error dialogs pop up saying ' unable to connect', and they do not stop popping up even after being dismissed.  I could understand this if there was an application running that had been using this disc - eg "Synchronize! Pro X", or if I'd deliberately mounted that disc for file sharing.  To eliminate this possibility, I have tried restarting both Macs, repeatedly, with file sharing turned off, etc etc.  I have used Spotlight to try to search for any file or script that even mentions the external disc, but found nothing.  It might be relevant that the older Mac is the one that I migrated to the new one.


Anyone else come across this?  Has anyone found a fix or can anyone suggest a cause?  I spent over an hour on the phone to Apple Support this morning but even with their help was unable to defeat this condition.

MacBook Pro, OS X Mountain Lion (10.8.1), 2.3 GHz Core i7

    Why is that Mac connected to your MBP? In any case System Preferences>Startup Disk. Select the disk you want to start up with and restart.

    I've got a very similar problem. However, in my case its not another Mac that it is trying to connect to but a NAS on my home network. Whenever I'm away from home and use my MBP it tries to connect to the NAS giving me the same error message as you get.

    Well, actually it has nothing to do with iphone (nor ipad) in my case since I have no iphone (yet) and have still not tried to connect my ipad to this MBP. I don't think iTunes is to blame either but i'll have to look more into that to know for sure.

    Just curious, when you migrated from the old mac to the new one, did you migrate everything, or just files, etc. ?

    Did you just move the user name from old to new, so you have the same user info on 2 machines?


    I would also check your iTunes prefs...

    it sounds like iTunes is trying to connect to the library on the old machine, thus trying to mount its disk.

    iTunes>Preferences>Advanced tab

    Check the location of the ITunes Media folder, it may be set to point to the old computer, rather than the new one.

    Let us know how you make out.
