Macs have been Windows and DOS compatible since the very beginning. Most recently the following options are available for running Windows on the Mac:
- Apple Boot Camp support website and user to user Discussion forum, Oracle Virtualbox, Parallels, Crossover Mac, VMWare are all Intel compatible solutions for running Windows native applications on Intel Macs.
- Darwine, iEmulator, Qemu are available for both PowerPC and Intel Macs. The website for Wintel for Mac OS X no longer exists, but was once an alternative.
- VirtualPC and Guest PC are options that will only run on PowerPC Macs.
Note: Options that run on Intel Macs generally are known as Virtualization, whereas options that run on PowerPC Macs are generally known as emulation.
The difference is that Intel Macs do not need to immitate the Intel CPU hardware using software. Because of this, PowerPC Macs generally handle still graphics, and text only based applications, where Intel Macs have no trouble with video or audio. Some Intel Macs are better suited to some games simply because of the graphics chip on board the Mac. If you have a question about a particular game, please don't hesitate into ask in the https://discussions.apple.com/community/windows_software/windows_compatibility forum if a game has been tried with certain virtualization under certain Mac model/vintage Mac. Also check the third party virtualization websites for forums to find out if your game has been tested under your Mac model and version of their virtualization engine.
Except for CrossOver, and WINE solutions, any solution running Windows is subject to the same security risks as running Windows on a PC within the
stated Windows environment itself. The Mac OS X environment only has its own much less hazardous security risks limited to trojan horses,
passing viruses on to Windows users, peer 2 peer software sending you applications which may not be tested as well as tying up your network, third party firewall software tying up your network applications when redundant on top of the built-in Mac OS X firewall, and issues running root account (using the sudo command line, or enabling it via a security application) based functions.
Mac OS X Security updates are found on Apple Knowledgebase How To 1222 article. Backup your data before installing anything new.
Anti-virus software and firewall software if installed on Mac OS X should be known to work with your installed operating system, and any updates you perform before performing those updates. CrossOver and WINE based solutions only exhibit issues for the individual application, and don't pose an operating system wide risk. If uncertain if necessary for your situation, don't hesitate to ask in the forum.
For each of these options, your Mac's hardware has been recommended to be at least the following:
G3 - Windows 95 or Windows 98, with 256 MB of RAM assigned to emulator and 2 GB assigned to swap file.
G4 - Windows 2000 or Windows ME, with 512 MB of RAM assigned to emulator, and 5 GB assigned to swapfile.
G5 - Windows XP, with 1 GB of RAM assigned to emulator, and 10 GB assigned to swapfile.
Intel Mac - XP or Vista same as XP requirements for G5 on virtualization solutions.
The PowerPC G3-G5 suggestions came from VirtualPC's original specs, whereas the Intel has been arbitrarily found to be the case. Double check
the software engine in question to ensure the specs aren't more rigorous for newer versions of Windows.
In some cases connecting a Mac formatted hard drive that supports Mac booting to a Windows machine is needed: MediaFour's MacDrive supports that.
There are volume size limitations to connecting media on 10.2.3 and earlier that are fixed in Mac OS X 10.3.
Mac OS X 10.6.4 and later support ExFat.
