Apple today seeded a revised third beta of macOS 15 Sequoia to developers for testing purposes, with the software coming a week after the initial release of the third beta.

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 and 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 updated third beta comes as we await the launch of a public beta for macOS Sequoia. Apple said that a version of macOS Sequoia would be available for public beta testers at some point in July.

Apple Music/TV is still 1.5.0.150

No changes as you can see looking at just these parameters
 
For the Europeans users.... "iPhone Mirroring is not available in your country or region"
 
It's been a while since i've installed a MacOS developer beta. If someone can refresh my memory, once the public beta and/or official gold release comes out, will a simple "Update OS" be sufficient ? Or does it usually require a clean install?
 
I have incorrect free space on all drives in the 14.6 Sonoma bata.

shows gigs of free space by macOS. but when saving files says drive is full.

Usually majority of the time after this revised dev beta 3 seed first PB seed, the build of dev/PB seeds are the same in future betas involving this cycle. The exception would be if some package has QA issues or security instances is involved.

Since nothing has really changed that is noticeable I would guess this revised build is more optimized then last weeks dev b3 seed. :cool:

I am having trouble installing this....am on beta 3 from last week. The update is found, it downloads the close to 15gb, goes into preparing update.... The preparation portion fails and I have to start all over. Tried it a few times... Anyone else?
