• Hacker News1Turn off Apple Intelligence on macOS 27 and get its disk space backRemoveMacAI is an open-source tool for Apple silicon Macs running macOS 27 that turns off Apple Intelligence features, deletes their downloaded models, and stops macOS from re-downloading them. It collects no data, keeps System Integrity Protection on, and all changes can be reverted.User control and consent over AI models:Some ask why anyone would remove small local models. Most say auto-installing ~12-25GB without an easy opt-out is anti-user, especially on 256GB Macs. Many don't want background AI and argue owners should decide what runs on hardware they paid for.macOS becoming bloated like Windows:Many compare needing debloat scripts on macOS to Windows tools like win11debloat and O&O ShutUp10. They see Apple following Microsoft toward enshittification, blame forced AI after Apple fell behind, and cite immutable system files that block removal.Leaving Apple and storage pricing:Some users report moving to Linux (KDE, GNOME, NixOS) over lockdown, consent prompts and bloat; others defend Apple's ecosystem convenience. Small base SSDs and costly upgrades worsen the issue. Commenters also share tips for deleting Xcode simulators via simctl.
• Reddit science1When the clocks stop changing. Research shows permanent standard time is the preferred choice for health, as it preserves morning light and aligns with human circadian biology. This can lead to improved sleep, mood, and overall health, particularly for vulnerable populationsAs Canada moves to end clock changes, a new analysis says governments must also choose permanent standard or daylight saving time. Health evidence favours standard time, as morning light supports body clocks, sleep and mood, while permanent DST brings dark winter mornings.Standard time vs permanent DST:Many prefer lighter evenings for after-work free time. Others back the study, saying morning light aids circadian rhythm, sleep and SAD. Some see preference clashing with health, while skeptics note chronotypes vary and no outcome studies compare the two options.Geography and time zone position:Users stress that latitude and position within wide time zones shape experiences, like 4am summer sunrises in the east and near-10am winter sunrises in Alberta. The failed 1974 US permanent DST trial is cited, and BC, Alberta and Manitoba adopting DST shows change happens.Change work hours, not clocks:Commenters argue schedules should adapt to the sun, citing flex hours, outdoor jobs and ignored research on later school starts. Critics counter that shifting clocks is effectively the same as shifting work hours, just simpler to coordinate centrally.
