We maintain a macOS product whose installer uses custom InstallerSection plugin bundles to show configuration panes during install. Starting with macOS 27 beta 6, all of our plugins stopped loading in Installer.app — the panes never appear and the install fails because our preinstall step depends on data the panes collect.

HirohikoKihara (via Ric Ford):

A third-party PKG installer that ships a custom Installer Plugin no longer displays one of its selection panes. The plugin bundle appears not to be loaded, so the pane that it provides is silently skipped and the user cannot choose the intended installation option.

FE:

This is regression for all latest updates eg. 15.8, 27.7, 28.0. This bug refuse open installer plugin for security reason in spite of the plugin and installer are correctly signed, notarized and works seamlessly in previous macOS versions. Workaround is copy installer (*.pkg) to local file system (home, desktop folder).

David Bushell (Mastodon, Hacker News):

I discovered that macOS 15.3 had enabled a feature that was phoning home every 15 minutes with personal data. And that I said “no” and turned it off.

[…]

And today I discovered that Apple had [in macOS 27] removed the “no” switch.

[…]

Digging through macOS 27 settings I turned off Siri (again). Of course, multiple unkillable Siri processes remain, stealing memory and writing data. For what purpose? Who knows. Note that they removed “Apple Intelligence” from this control.

[…]

All of this garbage was enabled after upgrading to macOS 27 despite me having “Apple Intelligence & Siri” turned off already. That was a rather explicit “no”, no?

Update (2026-10-02): Coeur (via HN Reader):

Author claims the system setting “Privacy & Security > Apple Intelligence Report > Report Duration” with its 3 options [Off | 15 minutes | 7 days] sends that data to Apple with that frequency. This is wrong - this is a transparency report so that you as a user can see everything that is getting sent to Apple as a part of Apple Intelligence. Nothing additionally is getting sent to apple if you switch this away from “Off”.

To me, the main point of the post was about the missing off switch for Apple Intelligence itself. Bushell was forced into enabling a feature (and storage use) he had specifically turned off, and there is no option to block his data from being sent to Private Cloud Compute. But, yes, the first sentence I quoted from Bushell is wrong. The report feature isn’t periodically sending data to Apple; it’s reporting what was already sent. Turning it off does not add any additional privacy, except from someone snooping the report file directly on your Mac. Apple’s wording explaining the report was confusing but has improved somewhat in recent versions.

macOS 26.7.1 (security, no enterprise, no developer, full installer):

This update provides bug fixes and security updates for your Mac.

macOS 15.8.1 (security, no enterprise, no developer, full installer):

This update provides bug fixes and security updates for your Mac.

Though not called out in the release notes, macOS 15.8.1 fixes the regression with RAW files.

For some reason, Apple removed the customary “is recommended for all users” from the release notes.
