Q: How do I upgrade from Tiger to Lion ?

I have OS X 10.4.11. In a recent update (added to the OS X), I now receive a message that FireFox no longer works with the version. What do I do now? I have been trying to get a response on upgrading to a later version of OS X and have not been able to obtain a simple straight forward answer. Very frustrating.

iMac (24-inch), Mac OS X (10.4.11)

    You will need to purchase a retail copy of Snow Leopard, available from the Apple Store, and install that. From there you can purchase Lion from the Mac App Store, or buy the installer in a USB flash driver from the Apple Store.

     

    Please note the system requirements of Lion before you purchase:

    You'll also probably need to update many of your applications and drivers, particularly if you have any applications that are not Intel-native; PowerPC-only applications will not run under Lion.

     

    You may just want to get a newer version of Firefox. The Mozilla project still has a version that will run on Mac OS X 10.4.11:
