Apple Inc. has released the first update to the latest version of its MacOS X operating system. Users of MacOS X 10.5 (Leopard) are strongly encouraged to download and install the 10.5.1 update which resolves a number of problems with the operating system.

The most important fix resolves a serious problem that could have led to loss of data when files were copied between hard disks. Other fixes have been made to wireless networking support inside MacOS X and the firewall which helps protect Macs from attack. There are also a large number of updates to applications that generally improve performance and reliability.

The 10.5.1 update is 110 Mb in size and works on the current range of Intel-based Macintoshes and older PowerPC Macs.

The easiest way to perform the update is to use the Software Update application which can be found inside System Preferences on the Dock, or through the Apple menu at the top-left of the screen. If you are a more experienced Mac user you can download the update from the Apple Website (linked below).

Please save all work and close any unnecessary applications before running the update. You will need to restart your computer after performing the update. Some Macs might take longer than normal to reboot the first time they are restarted after updating, this is nothing to worry about and will not occur on future start-ups.
