Apple released its latest OS X Server operating system last week, and surprised developers by giving limited access to the source code.
OS X Server is based on the Mach 2.5 microkernel and BSD 4.4 Unix, and ships with the Apache Web server, Apple's WebObjects application server, and Mac file services.
Apple has released parts of the operating system source code, to garner developer support. But Open Source advocates have complained that the components released, including Mach, BSD and Apache, are already Open Source.
Apple is touting OS X as a fast Web server. However, OS X does not support SMP (Symmetric Multi-Processing).
Neil Thomas, senior UK product manager at Apple, was cagey about Apple's plans for SMP. "We are researching SMP," he said.
"(OS X) has the potential scalability of Unix."
Another potential problem for the new OS is the lack of application support.
Although it will support a range of Unix applications out of the box, there will be no support for current Mac OS client applications until a client version of OS X is released in a year's time.
But Meta Group senior analyst Ashim Pal said: "This sounds similar to the PowerPC situation, when it was promised that non-PPC apps would run under PPC. They did run, but like a three-legged dog in wet cement. It won't hold up in the enterprise space without SMP."
