Mac Market Share Grows, Snow Leopard Bug Affects Some

Apple ChartInteractive Data Corp released its computer sales estimates for the third quarter and declared that Apple now has 9.4% of the U.S. market. This is up from last quarter and last year, even though the numbers include cheap netbooks and Apple has no netbook on the market. Apple still lags behind HP, Dell and Acer in quarterly sales.
A dangerous bug has been reported by some Snow Leopard users that wipes their home folders clean. It isn’t clear why this has happened to a few users, but the connection seems to be logging out of your account, logging into the guest account, and then logging back into your main account. Apple acknowledged that this happens, but only in rare cases. Keeping a Time Machine backup is the best way to protect yourself from this, or from any number of mishaps.
Apple has released a performance update for Leopard and Snow Leopard that “prevents hard drive stalls” — their notes don’t go any further explaining the issue or why the update is a specific download and not a part of the Software Update system.
