Q: I am running a MacBook Pro with 10.7.5 and I downloaded the OS X 10.10.2 Update Combo, however when I try and open the package the error message "This volume is used for TimeMachine-backups". Which is not true. I´m using TimeCapsule.

Yes I do.

I will do so. Thank you!!

Have just looked at it.

Think I fulfill the requirements.

But the problem persists. It won´t upgrade.

I am using a MacBook Pro (2010) with 2.53 GHz Intel Core i5, 4GB, 1067 MHz, DDR3, Startvolume Macintosh HD.

After downloading the package and starting upgrading it asks acceptance of the license-agreement. After that it asks for the volume were to install. And when I click on the Startvolume Macintosh HD (which is the only available on the machine) it says: "The volume is already being used for Time Machine-Backups".

It doesn´t offer to skip that point or to reconfigure the Time Machine settings.

The point is that my Time machine is not and has never used the Mac HD for Backups. In the past I have used an external drive and since 05/2014 I am using a Time Capsule which is appropriately addressed in the Time Machine settings.

Thanks for your help.

I will do so. :-))

Thank for your help.
