The Leather Sleeve was an exclusive accessory to the 12-inch MacBook but now Apple is expanding it to the MacBook Pro lineup.

Just when we thought the MacBook Pro was as good as it gets, Apple jumped right in and surprised as all with the new 2018 lineup that is capable of putting a lot of notebooks out there to shame. You can configure it with an i9 processor with 6 cores, 32GB of RAM, features a True Tone display and a brand new T2 chip that allows ‘Hey Siri.’ But that’s just the tip of the iceberg. There’s a lot of stuff that is brand new under the hood.
