Disadvatages of Mac OS

However, one thing that discourages users from using Mac OS is the limitation on the number of programs and software available for use under the OS. Because Mac OS has a lesser market compared to Windows, there are also lesser programs and applications that can be used. Some useful and popular applications are still not made available for Mac. Take for example the AutoCAD, which is used for computer-aided drafting. Even some famous computer games are only still exclusive for Windows OS. Many users who may have seen Mac OS good may settle for Windows considering that the programs and software they need can only be used through Windows.

advantages of Mac OS

Once upon a time Apple Computer issued a document called the "50 Mac Advantages," which later became the "75 Mac Advantages," a document which purported to list 75 different advantages the Mac OS had over its chief competitor, Microsoft Windows 95. The Advantages document was created as a promotional item to be handed out to Evangelistas. Origin of the 75 Mac Advantages describes the history of the development of the 75 advantages in more detail.

Despite some flaws, the original document listed substantive differences between Mac OS 8.1 and Windows 95, which were contemporary products. Among other problems, the original document had a disconcerting way of shifting between versions of Windows

to put the Mac OS in its best light. Overall, however, it was a very popular document with Mac advocates, and this series was based on an archival copy located at Alex Paterson's web site and used as source material.

In this series of articles, I have attempted to update the 75 Advantages to reflect the current state of the Mac OS (at 9.1/X) and the Windows operating system (now reflected by its Win2000, Me, and upcoming XP offerings). This being Low End Mac, the emphasis is on Win 98 and OS 9, but information about the other versions is included from time to time.

Meaning of Mac OS

Mac OS is the trademarked name for a series of graphical user interface-based operating systems developed by Apple Inc. (formerly Apple Computer, Inc.) for their Macintosh line of computer systems. The Macintosh user experience is credited with popularizing the graphical user interface. The original form of what Apple would later name the "Mac OS" was the integral and unnamed system software first introduced in 1984 with the original Macintosh, usually referred to simply as the System software.

Apple deliberately downplayed the existence of the operating system in the early years of the Macintosh to help make the machine appear more user-friendly and to distance it from other operating systems such as MS-DOS, which was more arcane and technically challenging. Much of this early system software was held in ROM, with updates typically provided free of charge by Apple dealers on floppy disk. As increasing disk storage capacity and performance gradually eliminated the need for fixing much of an advanced GUI operating system in ROM, Apple explored cloning while positioning major operating system upgrades as separate revenue-generating products, first with System 7.1 and System 7.5, then with Mac OS 7.6 in 1997.

Early versions of the Mac OS were compatible only with Motorola 68000-based Macintoshes. As Apple introduced computers with PowerPC hardware, the OS was upgraded to support this architecture as well. Mac OS 8.1 was the last version that could run on a 68000-class processor (the 68040). Mac OS X, which has superseded the "Classic" Mac OS, is compatible with both PowerPC and Intel processors through version 10.5 ("Leopard"). Version 10.6 ("Snow Leopard") supports only Intel processors.

  • Audio output capability

disadvantages of Windows Vista

Microsoft's Windows Vista has been a highly-anticipated operating system. Despite the impressive Aero Glass interface, the plethora of new features, and improved load times through ReadyBoost, Windows Vista has many disadvantages, most of which will be discussed below.

Windows Vista Advantages

SuperFetch prioritizes the programs you’re currently using and adapts to the way you work by tracking the programs you use frequently, at what times of day that programs are used and intelligently preloading these into memory.

So what so great about this you ask. If your computer is struggling to accommodate other tasks while your antivirus or backup utility or even Photoshop image processing is running, just plug in a USB 2.0 thumb drive to boost the memory and you can literally enjoy a performance boost instantly.

If you are using a laptop

, SuperFetch will lengthen your battery life too because your hard disk spin less frequently which translates to less power consumption.

As for me, the reason I upgraded my desktop RAM to 3GB recently is to take advantage of this feature.

Those I/O hangs will be a thing of the past as Vista is engineered to avoid them and the interference from rouge processes. Yes no more system hanging and pressing the reboot button finally.

From the security department, one of XP’s biggest security problem is that it promotes everybody who wants the ability to run a vast number of programs and conduct common activities as an Administrator. As a result anybody, including a malicious program that has the admin privileges is able to wreak havoc and exploit your system.
