Software Update Failure - Mid 2010 iMac / OSX 10.6.4

Question

I just received a never before opened or used iMac that was sitting in a storage room at work since 2010.  I have been attempting to update the software but it always fails.  I have tried by clicking on the Software Update button located under About this Mac and through Apples website.  Same error every time.  I don't need to do anything fancy, just wanted to update to the latest software / OSX Mavericks.  From what I have read my model is new enough and should upgrade, any help is appreciated.

Answer 1

If this Mac is still on OS X 10.6.4, you need to use the OS X Software Update feature in the OS X System Prefernces Panel to update to OS X 10.6.8.
This update will  give you access to the Mac App Store where you can upgrade your Mac to OS X Mavericks.
What year, screen size, CPU speed and amount of RAM installed?
To find out info about your system,
click on the Apple symbol in the upper left of the OS X main menu bar. A drop down menu appears.
Click About this Mac. A smaller popup window appears. This gives you basic info like what version of OS X your iMac is running, the speed of your iMac's CPU and how much RAM is installed.
Click on the button that says More Info. A larger window appears giving you a complete overview of your iMac's hardware specs.
Highlight all of this info and copy/paste all of this into another reply to this post, editing out your iMac's serial number before actually posting the reply.
