Re: [新聞] apple的新作業系統-Mac OS X Tiger
偷抄人家的一句話,寫得很好,我就不翻譯了:
Mac OS X is not based on FreeBSD, its based on a slightly derived version called BSD Darwin.
再補充:
The most widely-sold UNIX-based operating system, Mac OS X offers a unique combination of technical elements to the discerning geek, such as fine-grained multithreading, Mach 3.0 microkernel, FreeBSD services, tight hardware integration and SMP-safe drivers, as well as zero configuration networking. Tiger’s state-of-the-art kernel features improved SMP scalability and 64-bit virtual memory, while standards-based access control lists take UNIX permissions to the next level.
FreeBSD services != FreeBSD ...
FreeBSD 並不是用 Mach microkernel ...
再重複看上方網友的留言,要澄清我寫的這段並無針對上面內容的意思,只是想說明 FreeBSD 跟 MacOS 的關係。
是不是由 FeeBSD 改寫的 ... 恩 ... 應該說借用 FreeBSD 的殼吧,Mach microkernel 是可以用很多種殼來實作的。
其他的請參見作業系統的書 ... 小弟已經都忘光光了。
