Apple has opened the macOS 27 public beta. Here is which Macs are supported, what to back up, and how to install Golden Gate safely.
Apple opened access to the macOS 27 Golden Gate public beta on July 13, giving Mac users an early look at the next major operating system update. The final release is expected in fall 2026, but the software can already be tested through the free Apple Beta Software Program. The program provides access to preview versions of iOS, iPadOS, macOS, tvOS, watchOS, HomePod software and AirPods firmware, while also allowing testers to send feedback to Apple.
With Golden Gate, Apple is not rebuilding macOS from scratch. Instead, the company is focusing on several prominent features and a long list of practical refinements. The release adds new Siri AI capabilities powered by Apple Intelligence, further develops the Liquid Glass design, adjusts parts of the interface and improves everyday tools. Apple says macOS 27 should feel more responsive, convenient and stable than the previous version.
There is one important warning before installation: a public beta is not a finished release. It is intended for testing, so bugs, app incompatibilities and unexpected crashes are still possible. Installing it on the only Mac used for work makes sense only if those risks are acceptable.
One of the main changes in macOS 27 Golden Gate is an upgraded Siri AI. The assistant is more deeply integrated into the system and can answer questions, help perform actions in apps, search information from personal context and understand what is shown on the screen. Siri can be launched through Spotlight, while a separate app is available for longer conversations. Apple plans to roll out the new capabilities gradually, starting with English.
Another visible change is the continued development of Liquid Glass. In macOS Golden Gate, Apple has improved interface contrast and readability, unified toolbars, and refreshed window shapes and menu bar icons. A new control lets users adjust Liquid Glass transparency, ranging from an almost fully transparent look to a denser style that makes text easier to read.
The system also includes more practical improvements. Apple points to updates for AirDrop, Safari, Spotlight and other built-in tools. The feature set may still change, however, and some functions may remain unstable or depend on language and region.
It is better not to rush the update on a primary Mac. Beta versions exist specifically to uncover problems before a wide release. Even when the system works well in reviews or on another computer, there is no guarantee it will behave the same way with a particular set of apps and accessories.
Potential problems vary widely. Professional software may refuse to launch, while a plug-in, printer driver, VPN client, audio interface, banking app or corporate tool may work incorrectly. Increased battery drain, overheating, iCloud sync failures, and issues with external displays or peripherals are also possible.
The public beta is more suitable for a spare Mac that is not needed for urgent work. If there is no secondary computer, waiting for the final fall release is the safer option. This is especially important for designers, developers, video editors, musicians, journalists, teachers, business owners and other professionals who cannot afford downtime.
Before installing Golden Gate, a complete backup is essential, along with a clear plan for returning to a stable version of macOS.
macOS 27 draws a clear line for older Apple computers. According to Apple’s official compatibility page, Golden Gate supports only Macs with Apple silicon. Intel-based computers will not receive the new operating system.
MacBook Neo from 2026; MacBook Air with Apple silicon from 2020 or later; MacBook Pro with Apple silicon from 2020 or later; iMac with Apple silicon from 2021 or later; Mac mini with Apple silicon from 2020 or later; Mac Studio from 2022 or later; and Mac Pro with Apple silicon from 2023.
Several Intel Macs that support macOS Tahoe 26 cannot move to macOS 27. These include the 16-inch MacBook Pro from 2019, the 13-inch MacBook Pro from 2020 with four Thunderbolt 3 ports, the 2020 iMac and the 2019 Mac Pro. Before installation, it is worth opening System Information and checking the model, year and processor type.
A backup is not an optional precaution before installing beta software. It is a required step. If the update causes serious problems, a backup can restore important data and make it possible to return to a stable system.
The simplest option is Time Machine. Connect an external drive, open the Time Machine settings and wait until the backup finishes completely. The beta installation should not begin before that process is complete.
It is also sensible to save the most important files separately, including work projects, documents, photos, databases, archives, keys, passwords and app settings. iCloud is useful for synchronization, but it is not a substitute for a full local backup before a major operating system update.
The public beta is installed through the Apple Beta Software Program and the macOS update settings. First, the Apple Account used on the Mac must be enrolled in the beta program.
Open the Apple Beta Software Program website, sign in with the Apple Account and accept the participation terms if requested. Once enrollment is complete, compatible Macs can receive public beta releases from Apple.
Next, open “System Settings”, go to “General”, and select “Software Update”. Find “Beta Updates” in this window and click the information button beside it.
Select macOS 27 Public Beta from the drop-down list. The system should then display the available update. Click “Update Now”, or the equivalent button, to begin downloading and installing it.
The rest of the process is similar to a normal macOS update. The Mac downloads the installation files, prepares the system, restarts and completes the setup. The computer should not be turned off during this process, and a MacBook should remain connected to power.
After the first launch of macOS Golden Gate, it is better not to move every work task to the beta immediately. Start by checking Wi-Fi, Bluetooth, an external display, keyboard, mouse, printer, VPN, cloud services and essential apps.
Pay particular attention to software used every day: the browser, email client, messengers, document editors, video-calling apps and professional tools. This check can reveal incompatibilities before they disrupt urgent work.
Privacy settings, Apple Intelligence, Siri, iCloud and Time Machine should also be reviewed. After a major update, some system settings may change or ask for confirmation again.
A public beta is not only an opportunity to try features early. Apple also expects testers to help find bugs. Reports about app crashes, interface problems and unusual system behavior can be submitted through Feedback Assistant.
A useful report should describe what happened, the steps that led to the issue, whether it can be reproduced, the Mac model and the apps that were open. The more precise the report, the easier it is for developers to reproduce and fix the problem before the final release.
macOS 27 Golden Gate Public Beta should not be installed on a computer required for primary work, study, business or urgent projects. The same applies to machines that depend on specialized software, including video editors, music DAWs, CAD systems, development tools, corporate VPNs, accounting software and critical plug-ins.
Waiting is also the better choice for anyone who does not want to troubleshoot errors. A beta may appear stable, but it can still demand time, patience and a willingness to restore the system. For predictable everyday use, the final release remains the more sensible option.
For those with a spare Apple silicon Mac, an interest in new features and some tolerance for bugs, the Golden Gate public beta offers an early look at the future of macOS.
macOS 27 Golden Gate Public Beta has been available through the Apple Beta Software Program since July 13, 2026. It introduces the new Siri AI, further develops Liquid Glass and adds many system improvements, but it remains test software that may contain bugs and app incompatibilities. Apple’s official list includes only Macs with Apple silicon, leaving Intel machines behind.
Check compatibility, create a Time Machine backup and protect important work data before installing. Waiting for the stable fall release is safer for a single everyday Mac. On a spare device, the public beta can be enabled in just a few steps through System Settings and Software Update.
