Apple has released a new technical support bulletin that addresses an issue with MagSafe adapters becoming frayed or damaged. MagSafe adapters are the power supplies used in MacBooks and MacBook Pros.

Until now, Apple replaced damaged MagSafe adapters in Apple portables that were still under warranty. With the new support bulletin, Apple is instructing its service centers to replace any MagSafe adapter that shows cracks or is fraying, regardless of the state of the warranty.

If you have a MagSafe connector that is showing discoloration or any breaks or deformities in the rubber molding, you can take it to any Apple-authorized service center or retail Apple Store for evaluation and possible replacement.

It’s been a while since we've seen any new versions of the Mac ads featuring John Hodgman and Justin Long. Apple has been flooding the airwaves with iPhone ads lately, so it was a pleasant surprise to see the return of the Mac ads.

In his latest role, PC hides in a pizza box to try to ensnare college students when they shop for a notebook for school. Free pizza and college students seems like a natural match to me.

You can see the new ads at Apple's web site.
