Mac OS X update
Apple has released Mac OS X 10.5.7, adding a variety of bug fixes, security updates and expanded hardware support. The update provides additional RAW image support for cameras such as the Canon EOS Mark II, EOS 50D, Nikon D3X, Nikon D90 and Sony DSLR-A900, among others. Video playback and cursor movements have been improved for recent Macs with NVIDIA graphics components, while the expansion slot for the Mac Pro now correctly reports the PCIe slot settings.
An issue relating to the Dvorak keyboard layout has been improved from 10.5.6. The Unit Converter, Stocks, Weather and Movies widgets offer enhanced accuracy and reliability, while bugs have been fixed with Gmail and Yahoo contacts sync. Users without administration privileges can now add and remove printers by enabling Parental Controls.
The update improves iCal reliability with CalDav and automatic MobileMe syncing. Issues involving data sync between Mail and Notes have also been addressed, along with a problem that caused the BCC field to populate incorrectly when redirecting a message from the Sent mailbox.
Mac OS X 10.5.7 is available through a standalone installer or Software Update, with file sizes ranging from 286MB to 449MB depending on the particular system.
