To be fair, USB-C didn't exist when the first iPhone came out. Mini/Micro-USB did (I can never remember which one is smaller) but my
guess is they decided to stick with the 30-pin connector since it was marginally thinner and the extra pins meant it could output things that used more pins than USB, like HDMI, with a simple cable rather than an adapter with chips in it to "translate" the signal (as current Lightning-to-HDMI adapters do), but who knows.
I agree, but Magsafe was definitely a thing then, and even the 30 pin to TV cables for the iPods had to have a chip in them, then the ones from the iPods wouldn't work with the original iPhones, then the ones from the iPhone original, 3G and 3GS wouldn't work with the 4 or 4S...
Mag Safe was only ever used for power connectors. Maybe there's some sort of technical limitation why it couldn't work for data cables, or maybe it's a dumb patent-related thing (why did other hardware manufacturers never do their own versions of Mag Safe? Had to be a patent thing, right?). Certainly I'd like to see some sort of "break-away" USB-C cable for charging, sort of like the Xbox's wired controllers had. They could do that without changing the connectors.
It was a patent thing, Apple owned it patented and locked it down to fuck. All it needed though was another 1 pin to be completely USB2 compatible, and even USB3 and 3.1 as it was more than capable of providing exactly the same as USB3 and Lightning can, it's just they only focused on it being a power supply, not data.
I'd like to see USB-C on the iPhone. Everyone would complain about having to buy new cables just as they did with Lightning, but at least this time it'd be a universal connector
which you could also use for your laptop and whatever other devices you might have which use USB-C, so we're likely to end up with fewer cables in the long run. Let's do it. But there are also rumors that new iPhones won't have a cable connector at all, and only support wireless charging… I think I'd prefer to have the option to use USB-C.
I use these cables which are not exactly magsafe, but they work on my iPhones, my Macbook Pros and my Kindles, but it's a hack at best, and they are not cheap, because you have to buy the whole setup just for each cable, and if you need a normal charge point, and don't have a cable it's a pain in the arse to get the little connectors out.
Most of those early 32-bit EFI intel macs can support up to El Capitan, provided they have a 64-bit CPU.
Some can... None of the original 32bit EFI ones can though if they had onboard intel 950 or 3/3100/4000 series graphics chipsets, which was all of them.
Later ones that had discrete graphics, yeah they technically can...
I know "officially" Snow leopard was the cut off with the real original Mac Mini 1.5 Solo, but the intel GMA950 and 3000 series just couldn't support any acceleration after Lion/Mountain, and even that was a hack, and any intel chip higher than the 2.67 Core 2 Duo wouldn't work. I know, I tried...
It shouldn't have really supported Lion. Mountain Lion was honestly the furthest that particular model (and the first 2 plastic macbooks which were essentially a mac mini with a screen and keyboard) would go, but it wasn't great. No way any of those ones could do El Capitan... Just not possible. Not even with VESA graphics at 800x600. Impossible on the original intel chipsets.
The later models like the 2007-8 iMacs, Mac Minis with better graphics and MacBook Pros could, but the original Core solo even if upgraded to a Core2Duo 2.67 and 4GB could never go past Mountain Lion, and was even a push with Lion without 4GB ram.
The Intel GMA950/3000 chipsets in those just were not capable. They were probably most stable on Snow Leopard though, and that OS still got security updates for 8 years.
Anything better than those entry levels that had discrete graphics, like the 2007 iMacs and the 2007 MBP's, yeah, they could probably run El Capitan, and can also run Windows 10, but not gonna be a fun time...
