Comprehensive macOS 11.0 Big Sur review: the end of OS X era

John Voorhees / @johnvoorhees : Big Sur is a really big deal; a turning point in the Mac's history that doesn't come along very often.

Ars Technica Andrew Cunningham

Context & Ripple Effects

Big Sur is the payoff to a transition the related coverage has been building since High Sierra caught macOS up on fundamentals like APFS, followed by Mojave cutting off 32-bit apps — each release clearing legacy dependencies ahead of an architecture change.

The version bump to 11.0 lands simultaneously with Apple's M1 Macs, Rosetta 2 translation, and universal builds from developers like Pixelmator Pro, DaVinci Resolve, and BBEdit, making this the first macOS whose identity is defined by Apple silicon rather than Intel.

First-order effects

  • Developers named in the coverage — Pixelmator Pro, DaVinci Resolve, Darkroom, Ulysses, BBEdit — must ship universal binaries now, while x86-only apps fall back on Rosetta 2 translation on M1 Macs.
  • Mac users on Big Sur immediately face the stability complaints and bug reports recorded after launch, on top of an OS migration to new hardware.

Second-order effects

  • Xcode 12.2's cross-platform tooling pulls macOS, iOS, and iPadOS development closer together, pressuring independent Mac developers to maintain one codebase across all Apple platforms or lose the M1 install base.
  • The pro-hardware end of the lineup is exposed first: the later Mac Pro discontinuation with no successor planned follows logically once Apple silicon defines the roadmap, leaving workstation buyers with the transition-or-leave choice.

Third-order effects

  • If the pattern holds, the 'end of OS X' is structural, not cosmetic: macOS consolidates from a standalone desktop lineage into one runtime shared with iOS and iPadOS, with Apple controlling both chip and OS layers.
  • Third-party Mac software narrows toward vendors who can keep pace with annual silicon-and-OS transitions, echoing how the 32-bit cutoff already forced an app cull before the architecture switch.

The trend: macOS is completing its move from an Intel-era desktop OS into the desktop layer of a vertically integrated Apple-silicon platform spanning Mac, iPhone, and iPad.

    “This means that Apple knows when you're at home. When you're at work. What apps you open there, and how often. They know when you open Premiere over at a friend's house on their Wi-Fi, and they know when you open Tor Browser in a hotel.” 😞 https://sneak.berlin/...

    Dear @tim_cook, “It turns out that in the current version of the macOS, the OS sends to Apple a hash (unique identifier) of each and every program you run, when you run it.” Is this true? If so, how can you say you believe “privacy is a human right?” https://sneak.berlin/...

    Anyway, here I go again, reading noble intentions into a bullying monopolistic conglomerate that also happens to be the most valuable company in the world. This is the residue of two decades of goodwill built. They're spending it at a ferocious rate though!
  • @pentothalic Lucy on x
    TL;DR after the next macOS update, not even Little Snitch will be able to save us from Apple phoning home when, where, and what applications we use on our privately owned computers But don't worry, they insist they are the “privacy-focused” tech company https://sneak.berlin/...
  • @tapbot_paul Paul Haddad on x
    @reneritchie Sensationalist article aside there's some serious issues going on there. Apple designed things with a single point of failure and broke every Mac out there. It's likely that a bad actor/state could take advantage of this and DDOS a large number of Macs in the future.

    Well, this is... quite scary. And bad. And creepy. I didn't realize this was a thing, or that iOS/iPadOS (apparently) do the same thing. https://twitter.com/...

  • @dhh @dhh on x
    Shit like this is also just compounded when you embrace the notion of privacy as publicly as Apple has. Which is one of the things I really like about Apple! But you gotta stay congruent. These statements are not compatible with a phone-home scheme on every app launch. https://tw…
  • @dhh @dhh on x
    Apple is late to rendering its actions and intentions through the lens of a two-trillion dollar conglomerate with a proven record of using its systems and dominance for anti-competitive behavior. You can't simply go on good intentions any more! Don't think Apple employees realize
  • @dhh @dhh on x
    Worth noting the technical reason here. I don't think Apple is gathering this data because they want to sell it to advertisers (like a Google or Facebook would). Completely believe that the creators of this system thought they were doing right by users. But that's the conceit...
  • @herf Michael Herf on x
    This seems right to me: by checking every binary launched on macOS with OCSP, Apple has implemented full surveillance of what's going on with your computer, and it lets them track popular apps/etc. Not at all consistent with their privacy guarantees. https://sneak.berlin/...

    Hey Apple users: If you're now experiencing hangs launching apps on the Mac, I figured out the problem using Little Snitch. It's trustd connecting to https://ocsp.apple.com/ Denying that connection fixes it, because OCSP is a soft failure. (Disconnect internet also fixes.) https:…

    Unimaginable. macOS unable to open any non-Apple application. The joy of Proprietary software. MacOS sends hashes of every executable to Apple server when trustd and syspolicyd cannot do so. The entire macOS stops working. https://twitter.com/...
  • @minotauruk Chris Bagnall on x
    The huge privacy elephant in the room here is the implication that Apple gets a timestamped call home telling them exactly what program you are running whenever you start one. That's not cricket. There needs to be a way of turning this shite off. https://twitter.com/...

  • @stroughtonsmith Steve Troughton-Smith on x
    You gotta hand it to Apple's third-party dev community to have so many apps Apple-Silicon-native right out of the gate, including beta versions of Microsoft Office. There was always this idea of the ‘app gap’ for Microsoft & its modern efforts, but maybe it's just a developer gap
