Providing the PC has been made by Apple then it is perfectly legal to run the Mac OS on it. The legal terms and conditions for Mac OS X prevent it being used on non-Apple hardware.
Mac is computer software that isn't compatible on Windows. You shall have to create a hackintosh (building a computer with specific parts) to be able to run Mac osx. It does work the other way around. Mac can run Windows.
No. Using a virtual machine or a compatibility layer like Darwine, you can run Windows programs on Mac OS X, however.
Lego Island 1 was only released on the PC back in 1997 and never released on the Mac. As a result, the only way to play it on a Mac would be to run Windows on the Mac using virtual machine software such as VMWare. You can then install any Windows software while running Windows on the Mac.
One could run Windows XP on the Apple Mac if one were to essentially gut out the Apple Mac and turn it into a PC. There is no legal way of running a Windows operating system on top of an Apple operating system.
Apple wanted to be the software, and hardware company. That way Mac OS X is built for the Mac computers.
Using a program like this would be ok. Be sure to get one that is designed specifically for a Mac, that way you are sure to get the best software with the least amount of complications.
Sim City 2000 will not run on Mac OS X. It may run in the Classic environment which was included with older versions of Mac OS X but is not included in the latest versions 10.5 (Leopard) and 10.6 (Snow Leopard). An alternative approach would be software that emulates an older Mac such as SheepShaver (See links below) but either way it will probably take some tweaking to get it running.
Your options for this are relatively limited. The only way to run Windows applications without running a version of Windows in some form is with a compatibility library, such as Wine, CrossOver Mac, or Cider. These will generally have more limited compatiblity with Windows software than running a full operating system from Microsoft. Links to these software products can be found below.
Maybe; it depends on what you want, but I recommend Windows because it is better than Mac in almost every way. Mac has better built in software and has better free software available though.
No. The pirated software is still illegal. You have the legal copy; use it or replace it in the proper way.
Umm... Yes. But I'm talking about Mac OS X. If you want to run Mac OS Classic, well, sorry. You need another piece of software to emulate the environment, but if you have Mac OS X 10.3 or 10.4, you can run Classic Mode on it, but you would need a Mac OS Classic Installation CD __Mac OS__ is basically like Windows 95, Windows 98, Windows ME, etc, is to "Windows" today, it just refers to ANY Macintosh operating system in general. They have just made the phrase _MAC OS_ easier to distinguish between software that works on a Windows machine or a Mac and to show the software is made for the Mac only. Usually in the description it will give the actual parameters of how old the software will work, PowerPC or Intel Macs or OS 9, 10.2, 10.3, etc. OS-X refers to OS-10.1.x all the way to 10.6.6 as of today. OS-9 will only "boot" on older PowerPC machine's and "Classic" is an emulator in OS-X and will run "Most" of the OS-9 software on the "newer" Mac OS-X (10.1 to 10-4) "Classic" ended at OS-10.5.
The easiest way to downgrade a Mac so it looks like a Windows box is to install and run Windows on the Mac.
