Apple quietly introduced a new security lock adapter for the late-2013 Mac Pro today, making it available on its online store with shipping times of 24 hours.
The Mac Pro Security Lock Adapter lets you use a compatible Kensington or similar style third-party lock (sold separately) to keep your Mac Pro secure. The adapter attaches without tools and does not modify or damage the Mac. With a compatible lock connected, the Mac Pro Lock Adapter secures the housing to the enclosure, preventing access to internal components.
The security lock adapter enables users to physically secure a Mac Pro via an attachment at the bottom side of the desktop. As stated in Apple’s description, the adapter is compatible with most standard Kensington or similar lock products.
