Apple has released the Mac OS X Server 10.1.1 update.

The update makes the software more reliable and improves the performance of Apple file, Apache and Mail services - particularly when busy. Server administration, Samba (SMB) printer sharing and system-clock accuracy have also been improved.

Mac OS X Server's features also include QuickTime Streaming Server and Web Objects 5 deployment facilities. It's also based on Unix, which makes for a more reliable, high performance server package than Apple has been able to release in the past. This is boosted by the protected memory, pre-emptive multitasking, symmetric multiprocessing and advanced virtual memory capacities inherent in the OS. The solution also integrates many ease-of-use and security features.

The 3MB update is available for download from Apple.

The ten client version of Mac OS X 10.1 Server costs £340, while the unlimited client version costs £680 (prices ex.VAT).
