Back in highschool they also had those kiosks for adding funds to our student cards, and it would speak out like "Success". I saw someone crashed out the app (probably with a race condition, too) and used the ethernet to download audio files they prepared on the internal servers. The next day the kiosk began to yell hilarious stuff on success and that was hell of a week...

I get the desire to be compensated for the work that went into reproducing the Guided Access escape, but I have to agree that this is not a security issue.

Guided Access controls are in the Accessibility settings. Apple has marketed the feature as one of convenience.

And I think a hard reboot, at least this used to be true, will also exit the mode. (Hold power and home button or power and volume button combo.)

When I was in jail they had kiosks to order commissary snacks. I managed to take advantage of a race condition to crash out of the app onto the desktop. Typing was a pain because you had to use the on-screen keyboard, and I would only have a few minutes before a crowd of detainees would appear and start squawking excitedly, hoping that I could access their Facebook accounts for them, and drawing the attention of the…

I love reading comments like this, but I admit I'm always pretty curious how the poster ended up in jail. Care to share what your conviction was for?

They right clicked and pressed view source. I’m just surprised they let them out after committing such an heinous act…

You joke, but something like that is a terrifying possibility considering where things like device-attestation is headed, combined with a lack of understanding of the technology, especially the local level (e.g. I'm sure probably most of us here on HN got into trouble in elementary-school for "breaking the computers" or similar - I don't expect a local provincial magistrate to be any more understanding-of-things than the fuming head at my school)

Part of me wishes that Apple would license out iOS and macOS; and the chips they run on; for the specific purposes of embedded and industrial development. A MacBook, as good as it is for Office work, simply is not suitable on the construction site. If macOS was, say, licensed to Panasonic for their Toughbook line and it was only available to commercial customers, that would be a better arrangement. Or, another exampl…

I would hate to see this. That's essentially what the PC and Android markets are like, which are both full of shitty manufacturers making poorly supported throwaway hardware. The IoT market is even worse. Coming from Wintel, the vertical integration of Apple is a dream by comparison. Never had a single hour of downtime, compared to all the reformats and driver reinstalls and registry hacks and display glitches and su…

Oh, I joke because I know we are not that far away from it…

How's that? I wasn't a Mac user back then (except in school), but IBM-compatible PCs were still a headache back then. I over-applied thermal paste and misconfigured `config.sys` or set the wrong COM port baud rates more times than I can count...

MacOS 9 was a dog's breakfast of an OS. OS X wasn't released until 2001, so until then all those Mac users were forced to run a cooperatively schedulding OS without even protected memory (!!). A typical PowerMactinosh's uptime was measured in the single-digit hours, not the weeks you'd get from NT, or months for a Unix box.

...there's no excuse for that given Apple's vertical-integration.

Ah, I can believe that. The Macs we did have at school did not impress much. We saw the sad Mac face quite a lot, and had to use the debugger often ("g finder" IIRC).

I never had experience with NT until Windows XP. Did play around with MS-DOS, PC-DOS, Win 3.x and 9x, OS/2 Warp, and early Slackware though. None of those were particularly user-friendly or stable, lol, especially by today's standards. At the extreme end, I've fried a motherboard (shorted it somehow on first boot) and melted a laptop (tried to install Linux on it, apparently didn't have the fan drivers or something). Then early 3Dfx cards were also a pain to get working reliably, especially with SLI.

It was just a rough time for everyone, lol. I think the only things from that era that actually worked well were my PalmPilot and Casio calculator watch :)

I managed a college Mac computer lab (it was in the school of education, I guess Apple had a lock on schools with those brightly colored iMacs, which is what we had) from 1998-2000 when I was in graduate school. I don’t recall many problems, but maybe I’ve forgotten over the years.
