Apple has started a replacement program to fix MacBooks whose rubber surface is separating from the bottom case. The program covers MacBooks shipped between October 2009 and April 2011 that are exhibiting the problem. You can take an affected MacBook to an Apple Retail Store or Apple Authorized Service Provider to be fixed, or order a replacement kit online and do the work yourself. follow link
Track Bandwidth Use with VirusBarrier X6
If you have monthly bandwidth limits, it's useful to know how much data you have used so far to avoid overage charges or being shut off by your ISP. But how do you determine how much data your Mac has transferred? Open VirusBarrier X6's Traffic window to see both current and cumulative traffic, and you can also create warnings when your data usage - incoming, outgoing, or both - exceeds an amount you specify.
