Then, upgrade. If you don't like it you can then go back by simply booting from the clone, erasing your system disk and clone the clone back. You will then be back to exactly where you started. Much easier than a clean install followed by manual reinstallation of all your applications and data.</span></blockquote></div><br><div>I like the idea, but I am having trouble lately getting a decent install of any version of OS X…might be too soon yet on this install of Mt.
