Updating from panther to leopard

04-Jan-2020 04:46

Tiger was NOT an update of Panther and Leopard is NOT an update of Tiger. When Leopard is released it will replace, not update, Tiger.

If your current computer meets the machine specifications for Leopard, you can install Leopard on your computer regardless of what OS you are currently running.

Mac OS X 10.4 Tiger uses less memory than Leopard, supports Classic Mode on Power PC Macs, and, unlike Leopard, is supported on G3 Macs, so there are good reasons to install or reinstall it on your old Macs.

As Apple refines Mac OS X 10.5 Leopard and moves closer to the release of 10.6 Snow Leopard, the 10.4 Tiger version of OS X seems destined to fade into computing history.

Using Classic mode on a Power Mac G3 or better, it is still possible to run many applications compiled for the original 680×0-based Macs as far back as the 1980s.

Some older software or peripherals will only run under OS 9, and Classic mode extends their lifetime.
