macOS 27.0 RC Release Notes

Please note, the documentation below is supplied from Apple's update servers. We don't modify the contents of this documentation.

Experience the new Siri AI

Introducing Siri AI, an entirely new version of Siri powered by Apple Intelligence that's more personal, more capable, and more conversational. It is integrated into Spotlight, so you can search for answers about almost any topic right from where you already search for things across your system. It can draw on personal context to find things across your messages, mail, photos, and more. And it can get things done across your apps, just by asking. Revisit and resume past conversations in the new dedicated Siri app, synced with iCloud across your Apple devices. Siri AI is rolling out to users, and you can get started by turning it on in Settings.

Take action on what’s onscreen

With Visual Intelligence, you can select a window of your screen and Siri can answer questions or take action with what’s onscreen, like adding events to your calendar. You can access Visual Intelligence with a dedicated keyboard shortcut: Shift–Command–Space bar.

Powerful new ways to edit photos

Use intelligent photo editing tools to reframe a photo after it’s been taken with Spatial Reframing or expand your shot with the Extend tool. And enhancements to Clean Up let you remove distractions with better quality and more realistic infill, even when the scene is complex.

New tools to browse in Safari

Automatically group your tabs into topics, so related pages are easier to find. With Notify Me, Safari can monitor pages for changes like price drops or restocks and alert you when it’s time to act. Describe an Extension lets you use natural language to create custom extensions, like adding a button to save your favorite recipes.

Easily create Shortcuts using natural language

With Describe a Shortcut, you can automate daily tasks with a simple description and all of the required steps are assembled on your behalf. For example, you can describe a shortcut to automatically text your partner when you’re headed home from work with an estimated arrival time based on traffic.

Even more refined design

Updates to Liquid Glass improve readability, and a new slider lets you customize how it looks, from ultra-clear to fully tinted. Uniform toolbars, edge-to-edge sidebars, and more detailed app icons further elevate the design.

New child safety features

Powerful new parental controls help parents more easily manage what content their children can see, who they can communicate with, and when they have access to apps. Ask to Browse requires kids to request permission before visiting any new website in Safari. Communication Safety expands its protections to help keep conversations safe. Time Allowances gives parents more flexible ways to manage the time kids spend in apps across categories, and offers guidance based on expert research that’s tailored to a child’s age. Schedules help manage which apps kids have access to at different times of the day and across the week.

A more responsive and delightful experience

An expansive set of improvements makes your Mac even faster, more reliable, and easier to use. Better search in Spotlight and Mail helps you find what you’re looking for with greater ease. AirDrop Transfers and network file browsing happen faster. And many more improvements make your day-to-day use more enjoyable.

Installation Instructions

Always back up your devive before installing beta software. You can back up your Mac using iCloud, Time Machine, or another storage device.

Prerequisites

  • Second Mac: Another Mac of any model using macOS Sonoma 14 or later.
  • USB-C Cable: A high-quality USB-C cable to connect the two Macs.

Steps to Restore (and Update)

  1. Install Apple Configurator on the Second Mac
    • Download and install Apple Configurator from the Mac App Store on the second Mac if it’s not already installed.
  2. Put the Target MacBook into DFU Mode:
    • Shut down MacBook Pro (14-inch, M5, 2025) you want to restore.
    • Connect it to the second Mac using the USB-C cable.
    • Enter DFU (Device Firmware Update) mode.
    • In Apple Configurator on the second Mac, your MacBook Pro (14-inch, M5, 2025) should appear as a device in DFU mode.
  3. Apply the IPSW File:
    • Open Apple Configurator on the second Mac.
    • Select your MacBook Pro (14-inch, M5, 2025) in DFU mode from the device list.
    • Drag UniversalMac_27.0_26A428_Restore.ipsw file onto the device icon in Apple Configurator, or use the menu: Actions > Restore.
    • Confirm the action when prompted. This will erase the MacBook and install macOS 27.0 RC.
  4. Wait for the Process to Complete:
    • The restore process will take some time (15-30 minutes or more, depending on the file size and connection speed).
    • The MacBook’s screen may show a progress bar or Apple logo during the restore.
    • Once complete, your MacBook Pro (14-inch, M5, 2025) will restart automatically.
  5. Set Up the MacBook:
    • After the restore, your MacBook Pro (14-inch, M5, 2025) will boot into the setup assistant.
    • You can set it up as new or restore your data from a backup.

Note: Using an IPSW file with Apple Configurator always performs a full restore, erasing all data. There is no option to "update" macOS (preserving data) using an IPSW file directly.
