So, what to do if you’re concerned about securing your $1,000+ laptop at your workspace? Enter The Blade ($45) from Maclocks.com, a company that has long specialized in physical security solutions for Macs. This latest universal bracket lock allows you to secure any sized MacBook while still providing a reasonably elegant and low-profile design.
