Yes. However, Mac OS X 10.5 (Leopard) requires an 867 Mhz G4 processor. Some of the older eMacs do not have a processor this fast, and so cannot run Leopard without third-party workarounds.
yes it probably is hard to find a snow leopard as they can run as fast as a normal leopard
You can run Tiger, Leopard, and Snow Leopard. You cannot run Lion.
The snow leopard can run up to 64 kilometres per hour.
A MacBook will run Mac OS X 10.6 (Snow Leopard). If the MacBook is currently running 10.5 (Leopard) a copy of Snow Leopard will need to be purchased.
a snow leopard is the lightest leopard
The main difference between Mac OS X 10.5 (Leopard) and Mac OS X 10.6 (Snow Leopard) is that Leopard is the last version that will run on the older Power G4 and G5 processors. Snow Leopard and subsequent versions (such as Lion) will only run on Macs with an Intel processor. Consequently much of the differences between Leopard and Snow Leopard were in the inner workings of the system which were rewritten to take advantage of the Intel processors and to strip out the old PPC code resulting in a faster and smaller system.
An iMac G5 can only run Mac OS X 10.5 (Leopard) it cannot run 10.6 (Snow Leopard) or 10.7 (Lion). So the answer must be 'No'.
They use their very strong hind legs to run
Mac OS X 10.6 (Snow Leopard) is able to run both 32 Bit and 64 Bit software seamlessly. (See links below)
5GB is the space required to install Mac OS X Snow Leopard, but don't expect to be able to run Snow Leopard in that space. You will need at least 15 - 20GB to run Snow Leopard and its apps.
