A recent Apple update has fixed keyboard lockups on Leopard-based MacBooks and MacBook Pros, according to users on Apple's support forums.
The MacBook/MacBook Pro Software Update 1.1 that Apple posted to its download site on Tuesday was meant to put an end to the intermittent freezes users had reported on several support message threads for more than a month. "Some MacBook and MacBook Pro systems may occasionally experience a temporary suspension of keyboard input which can last a minute or longer," Appleadmitted in the brief description of the update.
Within days of Mac OS X 10.5 'Leopard' launching in late October, MacBook and MacBook Pro owners began complaining of infrequent yet persistent keyboard freezes that left them unable to use their computers.
Reports on the update's effect have been generally positive. "I was having intermittent keyboard dropouts before, none so far since," said a user identified as 'zig_k' on an Apple forum this week.
But not everyone was completely satisfied. "So far so good. But keyboard still sometimes seems a bit unresponsive. No lock-ups though," reported another user, 'daveinwoodland'.
Users must have updated Leopard to 10.5.1 before applying the keyboard patch, Apple said.
The 979K update installer can be downloaded from Apple's website.
