Apple has released what it calls “Performance Update 1.0,” an update to its Mac OS X 10.5 (Leopard) and 10.6 (Snow Leopard) operating systems for selected iMacs and MacBooks.
As Apple describes it — in typically brief fashion — in its Support pages, ”This update addresses intermittent hard drive related pauses reported by a small number of customers.”
Gotta love those detailed descriptions!
The update may be related to an EFI Firmware Update in June that some MacBook owners suspect was the cause of intermittent crashes and system freezes. This latest update may well put these problems to rest once and for all, except there’s something interesting about the name…that 1.0 suffix hints at the possibility of further revisions to come. A “Performance Update, Update” perhaps?
The update isn’t for everyone, however. It applies only to the following Mac models.
