Question: In 2015, Matt Stone listed this episode of South Park as his third favorite that used a screen-capturing program for what operating system?

<P0-S0> In computers, instant-on is the ability to boot nearly instantly, thus allowing to go online or to use a specific application without waiting for a PC's traditional operating system to launch. <P0-S1>  Instant-on technology is today mostly used on laptops, netbooks, and nettops because the user can boot up one program, instead of waiting for the PC's entire operating system to boot. <P0-S2>  For instance, a user may want to just launch a movie-playing program or launch an internet browser, without needing the whole operating system. <P0-S3>  There are and were true instant-on machines such as the Atari ST, as described in the Booting article. <P0-S4>  These machines had complete Operating Systems resident in ROM similar to the way in which the BIOS function is conventionally provided on current computer architectures. <P0-S5>  The "instant-on" concept as used here results from loading an OS, such as a legacy system DOS, with a small hard drive footprint. <P0-S6>  Latency inherent to mechanical drive performance can also be eliminated by using Live USB or Live SD flash memory to load systems at electronic speeds which are orders of magnitude faster. <SEP> <P1-S0> Snapz Pro X is a utility program for macOS developed by Ambrosia Software. <P1-S1>  It is designed to record movie-like screenshots of a computer monitor doing various actions, such as a user moving their mouse across the screen, clicking on desktop icons, typing text, et cetera. <P1-S2>  It has been used commercially in the production of books, such as O'Reilly Media's series, "The Missing Manual," and others. <P1-S3>  The program was also used by South Park to create the Make Love, Not Warcraft episode. <SEP> <P2-S0> The fifteenth season of the American animated sitcom "South Park" began airing on Comedy Central on April 27, 2011 and ended on November 16, 2011. <P2-S1>  In response to reactions to the mid-season finale episode "You're Getting Old", which seemed to insinuate that creators Trey Parker and Matt Stone were wrapping up the series, Comedy Central proclaimed through the media that "South Park" was renewed for two more seasons, and the duo were signed through 2013. <P2-S2>  Shortly before the airing of the season finale episode "The Poor Kid", "South Park" was extended again until 2016, taking the show to 20 seasons. <P2-S3>  Parker was the director and writer for all episodes, and Robert Lopez was the writer in this eleventh episode for the fifteenth season. <SEP> <P3-S0> "Make Love, Not Warcraft" is the eighth episode in the tenth season of the American animated television series "South Park". <P3-S1>  The 147th episode overall, it first aired on Comedy Central in the United States on October 4, 2006. <P3-S2>  In the episode, Cartman, Kyle, Stan, and Kenny enjoy playing the popular massively multiplayer online role-playing game "World of Warcraft". <P3-S3>  When a high level player goes around killing other players in the game, they start playing the game every day to try to stop him. <P3-S4>  The episode was written and directed by series co-creator Trey Parker. <P3-S5>  In 2015, he and co-creator Matt Stone listed it as their third favorite episode of the series.
