Apple today seeded the release candidate version of an upcoming macOS Sequoia 15.6 update to public beta testers and developers for testing purposes, with the software coming a week after Apple released the third macOS Sequoia 15.6 beta.

Testers can opt-in to the macOS Sequoia beta through the Software Update section of the System Settings app.

There's no word yet on what's included in macOS Sequoia 15.6, and no new features have been found in the betas so far. Apple's work on macOS Sequoia is winding down as it focuses on macOS Tahoe, the newest version of macOS that's coming in the fall.

These updates mostly provide SDK-compatibility with the next OS releases, so developers can more easily target the previous major OS release without compromising functionality for the current (next) major OS release.

Hopefully they will allow people to do a proper click-through, without having to hold down the Cmd button and who knows if they’re in a really good mood they might even “allow” people to right click and start a new document in a folder that way.

There are a small number of updates to Safari 18.6:


Hopefully the fixes around web extensions should make using uBlock Origin Lite for Safari (currently available through TestFlight) a lot more reliable (currently there is an issue with uBlock Origin and Cloudflare based verification freezing the page).
 
The update is stuck at installing Update..., after clicking Restart Now

I downloaded the update yesterday, then I clicked on Update Tonight, because my battery was at 20%, came home, connected the charger, felt asleep, in the morning clicked on Restart Now, did not restart, I waited, nothing, so I had to reboot using the Terminal, then tried again, but same thing as above, still waiting.
 
If memory serves, RC builds would be labeled without the "Beta number" suffix. Here we're getting a "Beta 4" with a release-style build number (12A34 vs 12A3456a).
