Mac Pro's $400 Wheels Have No Locks to Prevent Rolling

Since launch, Apple's Mac Pro has been the butt of jokes because of some of its expensive add-ons, such as the option to purchase wheels for an additional $400.
As pointed out by MKBHD in a review published this morning, those super pricy wheels have no locking mechanism, which could be major problem if a wheel-equipped ‌Mac Pro‌ is placed on a desk or a slick floor.#protip don't get the wheels if you keep this thing on your desk. There's no locks. pic.twitter.com/NfkqQiNKYC— Mar
