For years its been a dream of PC users to incorporate the beauty and functionality of a MAC GUI Operating system with the precision and dexterity of an X86 or X64 based architectural structure like that found in Windows Based operating systems. Novell tried it in the 1990s, and independent software developers and engineers are trying it everyday. The truth of the matter is that there is no conventional way to incorporate a MAC operating system with a PC, however with the wonderful invention of the emulator, this all can be possible.
Today we’ll be dealing with an application known as PEARPC. Pear PC is a very powerful virtual emulation application that enables users to platform independent OS architecture types on X86 machines. Meaning simply, PEAR PC enables a user to run foreign operating systems on Windows OS. This can be a very handy tool for many different types of computer users. PEARPC’s driver array even allows users to install and run applications native to the previously unsupported operating system. This makes it possible for a user to install any software application on any single machine, even if that application was originally “unsupported”.
To complete the install entirely you must equip yourself with several tools, the first being a RAR archive extractor. The extractor will be necessary in unraveling all of those APPLE disk image files. These files are vital origination points for the executable processes that your system will undergo during its configuration. These disk image files will be packaged in a simple RAR archive format. The user can choose from two sized disk images; a 3 GB format and a 6 GB format. The 3GB format will be more useful in exploring the operating system and its functionality, while the 6 GB format will offer some space for program usage. It is recommended that users who are just experimenting with MAC OSX use the 3 GB format to prevent from over-using host system resources. The sources are available for download below.

Secondly, it is extremely important to download the emulation software and the control panel. For our purposes, we will use the PEAR PC emulator and Pear PC control panel. Pear PC is a program that was developed in late 2005, under the GNU free-license act. It is revolutionary for the way that it utilizes core code, translating foreign code into architecture-independent code, and then to X86 based script. Although this process is considered speedy when implemented on a machine with vast capabilities, it is still a process that has been estimated to take up to 30 times longer than if the host system were executing it as native code. The Pear PC control panel will be extremely important in initially setting up the emulation process, and will be used as a seamless interface in creating host volumes. PEAR PC and the PEAR PC control panel are available for download at:

Finally (and most expensively), you will need a copy of MAC OSX. You will need to burn this disk image as an ISO file and download it to a local folder on your desktop. Most find that CD-Rs will not hold enough information for this image, and burning more than one disk will prohibit the image from being in a contiguous and error free format. Most choose to mount the disk in a virtual volume, or burn it on to a DVD.
Note that the editor of this content has only veryfied that MAC OSX Tiger and Jaguar are compatible.
Before commencing this process or any process that involves creating virtual disk volumes, make sure that there are at least 10 GB of hard memory available on the host system, and that there is enough memory to allocate to the host system, the emulator and the secondary operating system, as this process will not disable the host system during use. 1GB of memory will usually suffice in this setting. The PEAR PC will also allow the user to adjust the memory settings for the virtual OS, enabling the user to allocate the memory more appropriately, and file pages more efficiently on both the host and virtual systems. It is also important to remember to page files when using emulation software. To enable page filing on your Windows based operating system, go to CONTROL PANEL>SYSTEM>SYSTEM PROPERTIES>ADVANCED, and then click to open the Performance settings utility, and select change. Your system paging file minimum should be set to at least 250 MB. Since Windows page files are used to regulate system memory, the more you allocate to filing pages, the less likely a system crash is to occur when the virtual kernel is introduced.
When these files are being extracted, for organization’s sake, file them all away in the same folder. Not only will this give you an idea of where all appropriate files related to this process are, but it will make things much easier when it is time to use the PEAR PC control panel. It is usually best to save this directory in the C drive, due to the nature of its content. However, the Pear PC Control Panel is often best placed in the Program Files folder located under the C drive. This will direct the MAC OS emulation to the same area where most other programs are stored. It is also a good idea to create a shortcut for the Pear PC control panel on your desktop to assure ease of use.
At this point, it is time to employee the PEAR PC control panel. Click this application to run the Pear PC configuration utility. Choose FILE, NEW CONFIGURATION FILE and press continue. A new utility will open labeled “Create New Configuration File”. Direct the prompt to the disk location of the “PPC.exe” file in your PEAR PC folder (probably “c:PEARPCPPC.exe). The PPC.exe file is the actual emulation utility, it is in charge of translating architectural code. From here on out, when you choose to open MAC OSX, this executable file will be in charge of it. Do note that if PPC.exe is running in the background when you are not on MACOSX, it is safe to terminate.
For “Primary IDE device”, select the location of the disk image that you had burned earlier. IDE stands for Integrated Drive Electronics, and refers to the source origin of the operating system kernel. It is important to locate this component successfully, because this is where the “foreign” operating system is essentially located. Once the utility is completed, however, it is acceptable to delete the IDE, or disk image, from your hard drive as it is no longer needed. Please note that if you choose not to employee the “Create Virtual Hard Disk” utility, then the foreign operating system will choose to utilize the host system’s hard memory.
Memory Size
When creating the virtual memory size, it is important to remember efficiency. The more efficiently your virtual OS operates, the less efficiently your host will. It is generally a good idea to allow your host PC to utilize 75% of the physical memory, leaving the virtual OS to about 25%. For example, if your PC usually runs at about 1024 MB of memory, then it is generally good to run the virtual OS at about 256 MB. Do remember, when building your virtual PC, memory is of the essence. If you feel as though your host system’s memory capacity is not great enough to handle running two operating systems at once, then it is unwise to start this application to begin with. An ideal ratio for this exchange would be at least 2GB on the host, and 512 MB for the virtual OS.
Click on the bottom right-hand corner to proceed to the File Parameters Configuration Utility.
For the “PEAR PC additional options” tab, leave all of the fields to default. This will ensure the greatest efficiency when operating the virtual OS. If you are to adjust these settings, please be sure to page files, and have a total memory of more than 1GB.
Enabling the Networking Feature
To enable networking is basically asking for trouble. However, if you feel as though you must, verify that there is a check next to “enable networking”, and that, unless instructed directly to do otherwise, you leave the network address ,or MAC address at its default setting. This MAC address was imported from your Network Connections Utility, so it is most certainly correct. Also be sure to note your ISPs policy on limitations for DHCP clients. Some ISPs will only offer service on some outlets, to some clients. Be careful when enabling this feature.
CPU Emulation
Either CPU configuration will work. G4 is essentially a faster unit, but somehow the emulation processes the G3 much more efficiently, likely due to the simplistic nature of its processing.
COMPLETION!
To complete the configuration process, click continue. Name your configuration file ( something like MAC OSX should work well ) and select its destination! Click finish. Almost there!
Highlight your configuration file and make sure that the check box labeled “CD-ROM device is installed” is checked. Also be sure to locate the disk image file associated with the virtual drive, and select it. Click the play button and wait.
Please remember that this is a very involved process, and can take up to a full day to completely install the new OS. It may be necessary for you to reboot your host system SEVERAL TIMES before the changes will take effect. Keep in mind memory usage. Your host system is acting as a platform. In order for the virtual OS to function properly, there must a sturdy system in which it can rely on. So take care, integrate and have fun!
