When the 2012 MacBook Pros were released, we found that SATA 3.0 SSDs—such as the OWC Mercury EXTREME Pro 6G and the Mercury Electra 6G—exhibited poor performance and reliability in the 13-inch model when installed in the optical bay via an OWC Data Doubler, while the same SSDs in the 15-inch model worked just fine.
This was similar to what happened in 2011, where (ironically enough) the 13-inch models were the only ones able to handle our Mercury 6G SSDs in the optical bay at first. Eventually, though, an Apple firmware update resolved the problems in the 15-inch and 17-inch models in the main drive bay.

- Improve VPN reliability
- Identify and remove known variants of Mac Defender

While it’s great to see that Apple is moving towards the future with many aspects of its OS, there are several items they have not addressed yet, specifically on the 2011 MacBook Pros. Article Continues…
