MacOSX is sexy. It is made by AppleCorporation. Defined to give a place to reference [Carbon] and [Cocoa] and [Quartz] and all that stuff. Runs on [Darwin], a [BSD] variant on top of a [Mach] MicroKernel. One version newer than [MacOS9]. Is rather slow, on pretty much every platform you throw it at. If you were to run it on, say, an old [PowerMac] [G3], you may be forgiven for thinking that upgrading to a [PowerMac] [G4] would make it a lot faster. For the most part, you would be wrong. Also, you may think that the slowness is superficial and only applies to trivial GUI things like window resizing, file dialogs and pull down menus. You would be wrong about this, also. A call to sigaction(2) takes, by observation, around 20 times the time to execute under [MacOSX] than under [Linux] on the same platform. In real world times, that was around 3 seconds. However, subsequent revisions have become much better in times of feel of latency. While 10.0.x was quite painful on a G3, 10.2 was snappier (well, until you started swapping, at least) and apparently 10.3.x is further optimised. ---- http://www.kernelthread.com/mac/osx/ has a good description of the history of [MacOSX], and what exactly it is http://www.digitalmediatraining.com/products/panther/index.html/ has free video downloads for Mac OS X Panther Note: the Ⅹ in [MacOSX] has nothing to do with the X windowing system, it is the roman numeral for 10, which follows on from the previous version [MacOS9] ----- Part of CategoryOperatingSystem
