Review on Maclocks MBPR15BRWEDGE Laptop Security Lock and Bracket for MacBook Pro Retina 15-Inch by Russ Charmin

Unfortunately, Apple has decided to remove the security slot from the new MacBooks. This is a fairly safe method of blocking, although I wouldn't trust it as a permanent hard fix. Someone who is very vigorous with a screwdriver can remove it. However, I was looking for a solution that would keep someone out rather than permanently blocking them, and that fits the bill very well. The design and build are solid and go very well with the Mac's design. The only downside I see is that it requires a key and not a combination.
