MacBreak was the first podcast in 1080p high definition format, with the release of an episode on the TWiT web site in the format. According to Leo Laporte on the TWIT podcast, MacBreak caused bandwidth problems for its service provider, Libsyn.
MacBreak is a production of the TWiT.tv network in association with Pixel Corps. It is filmed in San Francisco, California on a greenscreen set at the San Francisco School of Digital Filmmaking. Each episode, the live-action greenscreen footage is keyed and composited over a virtual 3D set by members of the Pixel Corps. This process is explained in the "Road to 1080p" episodes.
Starting in April of 2007 with the release of MacBreak #65, "MacBreak Minutes" hosted by Merlin Mann and Kenji Kato began to appear along with full MacBreak episodes. MacBreak Minutes are short tips that consisted of an application or tool featured in a one-minute condensed video.
As of MacBreak #29, the opening titles were changed to reflect the new lineup of hosts. Amber MacArthur was no longer listed, replaced by Merlin Mann and Kendra Arimoto. Justine Ezarik became a host on January 12, 2007.
There used to be a "Whine" section where the hosts complain about certain features of various Mac OS X applications they wish would be improved. A running joke is that Alex Lindsay tends to pick products with exorbitant price tags, and thus the panel has created a unit of currency, the “Alex” which is equivalent to the retail price of the current version of Adobe Photoshop (approximately $700.00 US). It is sometimes used as a unit of price for the "Picks of the Week" segment, while free items are said to be “zero Alexes”. The show is often very casual and relaxed, and the hosts get off topic quite a bit which seems to contribute to the overall tone of the show. A recent feature on the show includes a special jingle first introduced by Merlin Mann and then supplied as a full blown song titled "Rathole!" which is played when the conversation veers very far off from the original topic. Another recurring theme is Leo Laporte's habit of buying Apple products just before they are discontinued, the price cut or the product changes. This started when he bought a Power Mac G4 Cube on the day it was discontinued. (This was referenced in episode 12; "Smokin", see: http://twit.tv/mbw12) It has become a joke throughout the shows, mostly between Merlin Mann and Scott Bourne.
The podcast has had a host of show notes writers, the current being Shash. He is often mentioned on the show and his comments, made via Skype during the show's recording, are sometimes talked about (for example in episode 70). Shash also appeared on the show during episode 77 ("Fries Done!"): see http://twit.tv/mbw77
