I first spotted his channel because he created a video highlighting that it's possible to install a PowerPC version of Snow Leopard, despite the fact that such an operating system was never officially released.
He screws up half the time, just like any regular user. But he keeps at it, and eventually, he succeeds. His most fascinating project so far is his attempt to restore a heavily modified Mac SE to its owner's bizarre specifications.
Essentially, Sean is taking on a computer the way Bob Vila would take on a master bath.
This is the kind of thing that works well on YouTube. But it's also the kind of thing that Jeffrey Katzenberg would rather be caught dead than being associated with.
The mindset of the Quibi founder has largely been the key reason why so many attempts at bringing technology coverage to television have sucked so terribly.
Of course, there are exceptions. The earliest show about tech I can remember is Computer Chronicles, the PBS show largely hosted by Stewart Cheifet, which highlighted emerging technologies decades before mainstream journalists had any idea what the heck any of this stuff could do. It had enough of a reputation among serious techies that Cheifet's longtime cohost was Gary Kildall, the guy who invented the CP/M operating system that MS-DOS so shamelessly ripped off. (The Internet Archive has every episode archived. It's great.)
Other notably good attempts are out there—CNET's fairly polished mid-'90s show on the USA Network is worth noting—but really the first cable channel to get technology coverage right was ZDTV, which came along around 1998, and was later renamed TechTV. It wasn't incredibly polished; it just felt like people in a studio geeking out.
TechTV was too pure and beautiful for this world, and its spirit was killed thanks to a merger with the gaming-focused channel G4. (And TechTV viewers, of course, hated the change.)
The Comcast-owned G4 was flashy, but it wasn't quite as good—it tried to turn tech coverage into something akin to its contemporary Spike TV, and it leaned hard into gamers—while leaving out people who just love gadgets.
(This is way too harsh, but the line is too good so I can't waste it: It was like watching a Monster Energy drink become sentient.)
So when G4 finally died off around 2014 or so after spending a few years as a rerun wasteland, I shed no tears. It started a few pretty good careers—Olivia Munn, for one, who I thought was one of the best parts of the derided Aaron Sorkin drama The Newsroom—but the cast-aside TechTV ultimately felt more valuable to the internet culture as a whole. A network whose alumni started Digg, Revision3, and This Week in Tech? That's a pretty good legacy! And unlike G4, which gestured toward a young-adult audience, TechTV's alums actually found it.
