<p>That is really poorly worded by Apple, because if I understand it correctly, the "Files & Folders" list is just a list of apps that have <i>requested</i> Full Disk Access/FDA (or other locations).<p>It's really confusing that some of those settings can be toggled on/off, while the Full Disk Access is greyed out and can only be toggled under "Privacy & Security".<p>To add to the confusion, toggling FDA off just protects a few selected folders that Apple decided are extra sensitive, like:<p><pre><code>  Messages                     ~/Library/Messages
  Safari browsing history      ~/Library/Safari
  Cookies                      ~/Library/Cookies
  Identity services            ~/Library/IdentityServices
  Spotlight data               ~/Library/Metadata/CoreSpotlight
  Phone call history           ~/Library/Application Support/CallHistoryDB
  Facetime data                ~/Library/Application Support/Facetime
  TCC database                 ~/Library/Application Support/com.apple.TCC.db
</code></pre>
"Normal" files and folders on your disk (including Desktop, Documents, Downloads, network volumes, and removable volumes) can always be accessed (even with FDA permission revoked!) after a simple prompt.

<p>Won't those cut right through the ANC just by volume alone? A domestic fire alarm is 85–120 dB, I don't think my airpods can mute that.<p>And of course there will always be fringe cases. What if I go to sleep with regular foam earplugs, what if I take a sleeping pill etc. Or what if the warning sound can't be engineered to fit a ANC friendly frequency, like somebody screaming, a car tire screech behind me and so on.</p>

<p>> Things leave your field a view much faster than anticipated.<p>Not sure about that. NASA has been using Kineto Tracking Mounts and ROTI (radar-assisted and optical tracking) since 1981. Those systems were developed for the Columbia launch. I find it hard to believe that today's computer-guided cameras would let anything slip out of frame unintentionally.</p>

<p>That's what I was thinking too. A clock without any culture-specific aspects could just rely on astronomy. The most objective form of that would just be a progress bar, from zenith to zenith. Perhaps with a marker half-way, and so on.</p>

<p>> they do nothing to change corporate behavior.<p>Well, they should. I've been on Mac since System 6.0.7. I've had a Mac Clone. I've been mocked by more Windows users for "using a toy computer" than I can remember. I remember (and briefly used) BeOS. I remember The Mac Performa-series fiasco. The Copland failure. Steve's return. The launch of OS X.<p>In all those years, I have NEVER witnessed such widespread dissatisfaction among long-time, loyal users, heavily invested in the Apple ecosystem. Users so frustrated with Apple's moronic decisions and the design of the OS that they are literally paying money to abandon it. I'm one of them. The frustration isn't rooted in nostalgia or resistance to change. It's the accumulation of what feels like contemptuous decision-making.<p>If that doesn't set off alarm bells in Cupertino, I guess it's just one more proof that parting ways is indeed the right call.</p>

<p>I think the narrative is more difficult now, as is visibility of goals. “Land a man on the Moon and return him safely” is a clear objective, while “decarbonize the global economy” or “make AI safe and useful” are fuzzier, and don’t give you a single flag‑planting moment.<p>But there's no lack of huge achievements. The Mars rovers are amazing: super-sonic parachutes, retro rockets, deploying a little helicopter with no real-time control is huge. So is planting JWST at the L2 point and unfolding it a million miles from earth.<p>Also, the NASA budget in the 1960's was 10 times higher.</p>

<p>> So you could sell singles with one hit song, and this would propel the "B-side" into people's homes as well<p>And that's also how Queen almost broke up in 1975.
