Veteran Mac publisher Take Control Books has introduced a new title designed to help Mac users upgrade to Mac OS X 10.5 'Leopard'.

Written by Joe Kissell, the $10 "Take Control of Upgrading to Leopard: Early-Bird Edition," guides readers through the upgrade process, including tips and advice on back-up in case of installation problems, clearing disk clutter and more.

Readers will get immediate access to the full version of the book as soon as the new OS goes on sale, but can prepare for upgrade now using the Early-Bird edition.

The full title will walk readers through the Leopard installation process, cover how to test a fresh Leopard installation, and explain how to clean up loose ends and troubleshoot problems after installation.
