If you want to install Mac on PC, you have two basic options how to do it: you can either install the Mac OS X operating system directly on a drive or use a Mac emulator for Windows. The former option gives you the best performance you can get, while the latter option is a lot simpler. So, which installation method you should choose? VICE is an emulator collection which emulates the C64, the C64-DTV, the C128, the VIC20, practically all PET models, the PLUS4 and the CBM-II (aka C610). It runs on Unix, MS-DOS, Win32, OS/2, Acorn RISC OS, BeOS, QNX 6.x, Amiga, GP2X or Mac OS X machines.

Bochs (pronounced 'box') is a portable IA-32 and x86-64IBM PC compatibleemulator and debugger mostly written in C++ and distributed as free software under the GNU Lesser General Public License. It supports emulation of the processor(s) (including protected mode), memory, disks, display, Ethernet, BIOS and common hardware peripherals of PCs.
Many guestoperating systems can be run using the emulator including DOS, several versions of Microsoft Windows, BSDs, Linux, Xenix and Rhapsody (precursor of Mac OS X). Bochs runs on many host operating systems, including Android, Linux, macOS, PlayStation 2, Windows, and Windows Mobile.

Bochs is mostly used for operating system development (when an emulated operating system crashes, it does not crash the host operating system, so the emulated OS can be debugged) and to run other guest operating systems inside already running host operating systems. It can also be used to run older software—such as PC games—which will not run on non-compatible, or too fast computers.
History[edit]
Bochs started as a program with a commercial license, at the price of US$25, for use as-is. If a user needed to link it to other software, that user would have to negotiate a special license. That changed on 22 March 2000, when Mandrakesoft (now Mandriva) bought Bochs from lead developer Kevin Lawton and released it for Linux under the GNU Lesser General Public License.[1]
Use[edit]
Bochs emulates the hardware needed by PC operating systems, including hard drives, CD drives, and floppy drives. It doesn't utilize any host CPU virtualization features, therefore is slower than most virtualization, rather than emulation software. It provides additional security by completely isolating the guest OS from the hardware. Bochs also has extensive debugging features. It is widely used for OS development, as it removes the need for constant system restarts (to test code).
BFE, described as a 'Graphical Debugger Interface for the Bochs PC Emulator', is a graphical interface for the debugger within the Bochs PC emulator that makes it possible to debug software step-by-step at the instruction and register level, much like Borland's Turbo Debugger.[5]
