The Mac operating system has been used on a variety of architectures, from the Motorola 68000 to the PowerPC 601 to the Intel Core 2 Duo. The latest release of Mac OS X requires a computer with an Intel processor.
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.
Mac OS X 10.6 (Snow Leopard) will not work on a Mac with a G4 processor as it requires an Intel processor based Mac. A G4 (867 MHz and faster) can run Mac OS X 10.5 (Leopard).
The eMacs were discontinued in 2006. The earlier versions with a G4 processor running at less than 1GHz can run Mac OS X 10.4 (Tiger). The later versions with a G4 Processor running faster than 1GHz can run Mac OS X 10.5 (Leopard). Select About this Mac from the Apple menu (top left) to determine the speed of the processor.
In order to run a Windows OS you need to have an Intel processor. Mac OS X will only run on an apple computer. Some apple computers are using an Intel processor so you can run a Windows OS or Mac OS.
If it has an Intel or G5 processor, then yes. If it has a G3 processor, then no. If it has a G4 processor, then it depends on the processor speed.
Mac OS X 10.4 "Tiger" will run on a PowerPC G4/800MHz machine. It is the latest OS that Apple will support on that processor, however. At this writing (January 2010), Mac OS X 10.4.11 is the latest version of Tiger.
Providing the Intel processor is in an Apple Mac computer, and the rest of the computer parts are present too, then Mac OS X can be installed.
Although the appearance of Mac OS X 10.5 (Leopard) and Mac OS X 10.6 (Snow Leopard) is similar there are many differences in the workings of the two systems. Most notably Snow Leopard requires a Mac with an Intel processor whereas Leopard will run on earlier Macs with G4 or G5 Power PC processor as well as the newer Intel based Macs.
Edius only works with the Windows operating system so will not run on Mac OS X. If you have a Mac with an Intel processor (any recent one) then you can install Windows on the Mac and then run Edius. Alternatives that will work with Mac OS X are Apple's Final Cut Pro or Adobe's Premiere.
I chose Mac Os because i can't use mac os
If the Mac has an Intel processor (if it is not too old it will do) it can be downgraded to use the Windows operating system. This can be done with Mac OS X's BootCamp utility or with virtualisation software such as Parallels or Fusion. (See links below)
Yes, you can upgrade to Lion from any iMac that uses the Intel processor. But the newest OS is Mountain Lion.
