Apple Seeds macOS Sequoia Release Candidate to Developers

Apple today seeded the release candidate version of macOS 15 Sequoia update to developers for testing purposes, with the software coming a week after the release of the eighth beta.

macOS Sequoia Feature
Registered developers can opt-in to the macOS Sequoia beta through the Software Update section of the System Settings app. An Apple ID associated with an Apple Developer account is required to get the beta.

macOS Sequoia includes iPhone Mirroring, which allows you to control your locked iPhone from your Mac. You can open and use iPhone apps, interact with notifications, and drag and drop files between your iPhone and Mac and vice versa.

There are new options for window tiling, and dragging a window to the edge of the display will suggest a tiled location to make it easier to use multiple apps at once. Apple is adding a Passwords app for managing passwords, Safari can summarize websites, surface key information, and Notes has support for live audio transcription and math equations.

All of the Apple Intelligence features coming to iOS 18 will also be available in macOS Sequoia, but Apple does not plan to add these until later in the beta testing process. ‌Apple Intelligence‌ includes Writing Tools for editing, proofreading, and summarizing text in apps, and an Image Playground allows for AI images to be created from prompts.

Custom emoji or "Genmoji" can be created for any situation and used just like emoji, and Siri is getting much smarter. ‌Siri‌ will be able to do more in apps and will better understand requests, especially those made in regard to on-screen content.

the rc is also available to public beta testers so just check build - if it is 24A335 then it is rc.

Yep, same for me. No NTFS writing for now
Paragon has updated theirs to make it sequoia compatible but I'm still having the same issues though.
I go through the whole process of rebuilding the systems extensions cache and it restarts my Mac mini, and it still tells me I gotta do it again. I think this might be an issue on Apple's side

Heads up everyone. I installed the RC. Everything was fine but I had pre "Sequoia RC" issues on my User account that I wanted to check out. So I started up in macOS recovery and used the [ICODE]RepairHomePermissions[/ICODE] command in Terminal. That ran fine and all seemed well, but when I rebooted my home folder was completely goofed. I couldn't access any of my user folders "Documents, Downloads, etc " because they were owned by root! So don't do that!

I couldn't reinstall from my Time Machine backup while in Recovery. I was told to use Migration Assistant. I finally got that running on my goofed system and found out there wasn't enough room on the SSD to install from Time Machine. Luckily I had been holding onto to a used Apple 1TB SSD. Took my iMac apart, installed the 1TB SSD rebooted, installed Mojave first, found and downloaded the Sonoma combo updater using Safari, installed that, rebooted, added my iCloud account, then ran Migration Assistant and installed my last backup from Time Machine. Took over 4 hours including taking apart the iMac and putting it back together again.

I'm betting there's going to be another build of macOS 15.0 that's different from the current RC build. I went from Sonoma 14.6.1 to the RC of Sequoia (build 24A335) and the Feedback app was installed. No way they're going to ship the final build of 15.0 with the Feedback app.
The feedback app is always there, even in release versions of macOS, in /System/Library/CoreServices/Applications. It's just not normally in the dock.
