how do I upgrade to maverick os on a iMac5 model?
OS X Snow Leopard 10.6.8, the latest version is currently installed.
iMac, Mac OS X (10.6.8)
An iMac prior to the iMac7,1 model isn't capable of running Mountain Lion or Mavericks. If desired, you can buy a download code for Lion 10.7; back up your data before upgrading. Lion doesn't support PowerPC software such as Microsoft Office 2004 or earlier.
