Mac OS X On Intel.. Let's Give It A Spin
March 19th, 2001
March 19th, 2001
The future of the Mac OS, at least for the next few years, rests on a Unix foundation. For Observers who are not aware of it, Unix is a system available in many variations, including the well-known Linux. The underpinning of Mac OS X comes from a version of Unix called BSD*. One of the interesting things about Unix systems is that most of the various versions run on PC boxes, meaning computers equipped with Intel processors and AMD processors. This includes the very same BSD variant on which Mac OS X is based.
* BSD stands for Berkeley Software Distribution. The University of California at Berkeley's Computer Systems Research Group, when tinkering with the Unix operating system, made enough significant changes and added enough features, that it was practically a new OS. Therefore, they saw the idea of a separate distribution named BSD as being appropriate. |
You can see it coming. Many Mac users are flirting, at least intellectually, with the idea of Mac OS X running on Intel processors. I have seen it discussed in all types of forums, mailing lists and Web editorials. Even The Mac Observer's forums have been witness to this debate. It is a thought-provoking question; sacred cow territory.
Before we start
Could it be done? Could Apple, if such was its desire, produce a version of Mac OS X that runs on Intel based computers?
According to Scott Anguish of Stepwise, who was a NeXTStep and OpenStep developer before Apple acquired the system, porting Mac OS X to PC boxes would not prove to be too much of an obstacle: 'It could be done rather easily.. we're talking about writing new drivers and bringing it up on the PC, something that has already been done with Darwin now.'
John Welch, a network administrator who has dealt with every Macintosh system since 1984 and coauthored the Mac OS X Server Administrator's Guide, sees some difficulty. Says Mr. Welch, 'Intel chips are register starved, and microcode heavy. You also have to recode for a crappy vector implementation, slow floating point (this would just kill Quartz), and the fact that RAMBUS is only fast with streaming data, and slow at everything else. That 20-stage pipeline is a pain too, and if you miss, it takes forever to flush it.'
So, according to the two of them, it would be hard, but not impossible. What would it imply for developers?
Mr. Anguish explains, 'If you have no assembly [code], and you are able to isolate your code areas where the endian-ness is an issue it should be easy. But Classic would be a loss and the above could be much harder on Carbon than Cocoa. We've done this on Cocoa before in the Rhapsody days.. and it was trivial.' John Welch adds that developing for both versions of Mac OS X would require different code, meaning two different versions of the same application.
It sounds troublesome. Developers who keep up with Macintosh and Windows versions already handle lots of work. The idea of adding another edition would simply be a burden for them. Developer support is key to the success of an operating system environment. This makes me wonder if such a project, while technically doable, would be a curse from the start.
What it would imply for AppleApple is a hardware company. It generates profit from hardware sales and it would have to multiply its software sales exponentially to make up for loss of hardware vending.
An Intel version of Mac OS X would likely harm such sales. Without the obligation to buy Apple machines to run Mac OS X, what would justify the purchase of an iMac, an iBook, a PowerBook or a G4? Imagine if Apple goes ahead and does the port, and that the new system becomes incredibly popular with PC buyers. The Macintosh would suffer in the hardware arena when competing with inexpensive PC boxes. As Apple's financial situation depends on hardware sales, it would be a nightmare.

Of course, Apple could think of building its own PC hardware, but it would add on its development burden. Also, to lock buyers into buying Apple hardware, the company would have to lock Mac OS X to a proprietary ROM chip that only they had the right to sell. Research and development require large sums of money. Remember that Apple cannot manufacture cheap machines with 'PC clone-like prices' because good profit margins are vital to its net income. Competition with Dell, Compaq and others on the x86 turf is not even an option. This means that to avoid trouble, Apple would have to choose between the Mac and Intel boxes.
At that rate, why not keep the Macintosh as it is?!? Exiled lab mac os. I bet that if you look a the issue from that perspective, it will cool off many people's feelings about Intel processors.
There are other reasons to believe that Mac OS X should never be available for Intel-based machines.
What about Motorola? Although Apple and 'Moto' have gone through hard times with their processor development and manufacturing, we heard reports about 733 MHz chips being overproduced (!) and that Gigahertz chips will be coming later this year. It also seems that they have been business partners forever. The very idea of beginning a 'menage a trois' involving Intel sounds impossible and a wholesale move to Intel/AMD is no better. Moreover, Apple invested hard cash into PowerPC development with Motorola and IBM. Can it afford to alter its strategy? The PowerPC is Apple's fruit. I am not sure if taking any focus away from it would pay off.
From my perspective, an Intel compatible version of Mac OS X would be doable, but troublesome. It would not be worth the effort if it did not bring substantial new sales in. The Macintosh is Apple's bread and butter, and the company cannot afford to risk any of it.
I have the feeling that such an adventure would turn into a nightmare for Apple and developers alike. The perspective of Apple becoming a software company or selling PC boxes would not excite many people, except maybe a few geeks here and there. If Apple wants success, it needs to go with strength, not to dive into a risky scheme where the likelihood of triumph is anything but certain.
Apple, never let this strange idea tempt you. Let it live as a pipe dream in a few people's minds, but DON'T go any further!

Spinning Wait Cursor as seen in OS X El Capitan
The spinning pinwheel is a variation of the mouse pointer arrow, used in Apple's macOS to indicate that an application is busy.[1]
Officially, the macOS Human Interface Guidelines refers to it as the spinning wait cursor,[2] but it is also known by other names, including the spinning beach ball[3], the spinning wheel of death[4], the spinning beach ball of death,[5] or the ferris wheel of death.

History[edit]
A wristwatch was the first wait cursor in early versions of the classic Mac OS. Apple's HyperCard first popularized animated cursors, including a black-and-white spinning quartered circle resembling a beach ball. The beach-ball cursor was also adopted to indicate running script code in the HyperTalk-like AppleScript. The cursors could be advanced by repeated HyperTalk invocations of 'set cursor to busy'.
Wait cursors are activated by applications performing lengthy operations. Some versions of the Apple Installer used an animated 'counting hand' cursor. Other applications provided their own theme-appropriate custom cursors, such as a revolving Yin Yang symbol, Fetch's running dog, Retrospect's spinning tape, and Pro Tools' tapping fingers. Apple provided standard interfaces for animating cursors: originally the Cursor Utilities (SpinCursor, RotateCursor)[6] and, in Mac OS 8 and later, the Appearance Manager (SetAnimatedThemeCursor).[7]

From NeXTStep to Mac OS X[edit]
NeXTStep monochrome (2 bit)
NeXTStep 1.0 used a monochrome icon resembling a spinning magneto-optical disk.[a] Some NeXT computers included an optical drive which was often slower than a magnetic hard drive and so was a common reason for the wait cursor to appear.
NeXTStep color (12 bit)
When color support was added in NeXTStep 2.0, color versions of all icons were added. The wait cursor was updated to reflect the bright rainbow surface of these removable disks, and that icon remained even when later machines began using hard disk drives as primary storage. Contemporary CD Rom drives were even slower (at 1x, 150 kbit/s).[b]
Mac OS X (24 bit)
With the arrival of Mac OS X the wait cursor was often called the 'spinning beach ball' in the press,[8] Crystal heart mac os. presumably by authors not knowing its NeXT history or relating it to the hypercard wait cursor.
The two-dimensional appearance was kept essentially unchanged[c] from NeXT to Rhapsody/Mac OS X Server 1.0 which otherwise had a user interface design resembling Mac OS 8/Platinum theme, and through Mac OS X 10.0/Cheetah and Mac OS X 10.1/Puma, which introduced the Aqua user interface theme.
Mac OS X 10.2/Jaguar gave the cursor a glossy rounded 'gumdrop' look in keeping with other OS X interface elements.[9]In OS X 10.10, the entire pinwheel rotates (previously only the overlaying translucent layer moved).With OS X 10.11 El Capitan the spinning wait-cursor's design was updated. It now has less shadowing and has brighter, more solid colors to better match the design of the user interface. The colors also turn with the spinning, not just the texture.
System usage[edit]
In single-tasking operating systems like the original Macintosh operating system, the wait cursor might indicate that the computer was completely unresponsive to user input, or just indicate that response may temporarily be slower than usual due to disk access. This changed in multitasking operating systems such as System Software 5, where it is usually possible to switch to another application and continue to work there. Individual applications could also choose to display the wait cursor during long operations (and these were often able to be cancelled with a keyboard command).
After the transition to Mac OS X (macOS), Apple narrowed the wait cursor meaning. The display of the wait cursor is now controlled only by the operating system, not by the application. This could indicate that the application was in an infinite loop, or just performing a lengthy operation and ignoring events. Each application has an event queue that receives events from the operating system (for example, key presses and mouse button clicks); and if an application takes longer than 2 seconds[10] to process the events in its event queue (regardless of the cause), the operating system displays the wait cursor whenever the cursor hovers over that application's windows.
This is meant to indicate that the application is temporarily unresponsive, a state from which the application should recover. It also may indicate that all or part of the application has entered an unrecoverable state or an infinite loop. During this time the user may be prevented from closing, resizing, or even minimizing the windows of the affected application (although moving the window is still possible in OS X, as well as previously hidden parts of the window being usually redrawn, even when the application is otherwise unresponsive). While one application is unresponsive, typically other applications are usable. File system and network delays are another common cause.
Guidelines, tools and methods for developers[edit]
By default, events (and any actions they initiate) are processed sequentially, which works well when each event involves a trivial amount of processing, the spinning wait cursor appearing until the operation is complete. If processing takes long, the application will appear unresponsive. Developers may prevent this by using separate threads for lengthy processing, allowing the application's main thread to continue responding to external events. However, this greatly increases the application complexity. Another approach is to divide the work into smaller packets and use NSRunLoop or Grand Central Dispatch.
- Bugs in applications can cause them to stop responding to events; for instance, an infinite loop or a deadlock. Applications thus afflicted rarely recover.
- Problems with the virtual memory system—such as slow paging caused by a spun-down hard disk or disk read-errors—will cause the wait cursor to appear across multiple applications, until the hard disk and virtual memory system recover.
Instruments is an application that comes with the Mac OS X Developer Tools. Along with its other functions, it allows the user to monitor and sample applications that are either not responding or performing a lengthy operation. Each time an application does not respond and the spinning wait cursor is activated, Instruments can sample the process to determine which code is causing the application to stop responding. With this information, the developer can rewrite code to avoid the cursor being activated.
Apple's guidelines suggest that developers try to avoid invoking the spinning wait cursor, and suggest other user interface indicators, such as an asynchronous progress indicator.
Alternate names[edit]
The spinning wait cursor is commonly referred to as the (Spinning) x (of Death/Doom).[d] The most common words or phrases x can be replaced with include:
- Disk
- (Beach) Ball[11][12]
- (Rainbow) wheel
- Pinwheel
- Pizza[e]
- Pie
- Marble
- Lollipop
