What You Need to Know About macOS Golden Gate

MacOS Golden Gate

Apple’s latest operating system, macOS 27 Golden Gate, brings a more refined interface, a substantially upgraded Siri and further developments in Apple Intelligence. For businesses, however, the most significant change is not something users will see on screen: this is the first macOS release to leave Intel-based Macs behind entirely.

As with every major update, the question is not simply what is new, but whether it is right for your organisation. Here we look at the key features, hardware requirements and administration considerations, together with what our compatibility testing means for businesses planning an upgrade.

New Name, Compatible Devices & Minimum Specs

Golden Gate continues the numbering system introduced with macOS Tahoe, aligning the operating system version with its primary year of use. macOS 27 takes its name from the Golden Gate strait, which connects San Francisco Bay to the Pacific Ocean.

The name follows a familiar pattern, but the hardware requirements mark an important change. Whilst Tahoe retained support for a small number of Intel Macs, Golden Gate runs exclusively on Apple Silicon. Any Intel device currently running macOS 26 will remain on Tahoe and cannot receive this upgrade.

The full compatibility list is as follows:

• MacBook Air with Apple Silicon (2020 and later)
• MacBook Pro with Apple Silicon (2020 and later)
• iMac with Apple Silicon (2021 and later)
• Mac mini with Apple Silicon (2020 and later)
• Mac Studio (2022 and later)
• Mac Pro with Apple Silicon (2023 and later)
• MacBook Neo (2026 and later)

For organisations already using Apple Silicon throughout their estate, this should make compatibility relatively straightforward. For businesses still relying on Intel hardware, it is a clear prompt to review replacement plans. Those devices may remain useful on an older operating system, but they are no longer part of Apple’s future macOS development.

Apple does not publish a separate set of minimum specifications beyond its supported device list. However, being able to install an operating system does not necessarily mean a device will deliver the experience your users need. Our general recommendations for business devices are:

• A minimum of 16GB RAM.
• A 512GB SSD.
• An Apple Silicon M-series processor.
• At least 50GB of free space before upgrading.

For new purchases expected to remain in service for several years, 24GB or 32GB of memory is worth considering. As AI-assisted features become more widely used, leaving some headroom is likely to be more useful than buying to today’s minimum requirements.

Apple Intelligence Hardware Requirements

Although all supported Apple Silicon Macs can run Golden Gate, not every device receives the same AI capabilities. Apple Intelligence uses the AFM 3 Core model across supported Macs, whilst the AFM 3 Advanced model requires an M3-family processor or newer and at least 12GB RAM.

At present, the Advanced model supports more expressive Siri voices and improved dictation. The distinction is worth keeping in mind when buying new hardware: operating system compatibility and access to every AI feature are not necessarily the same thing.

Additional Storage Considerations

One practical change identified during testing is the storage used by Apple Intelligence. In previous macOS versions, disabling Apple Intelligence also removed its locally stored models. In Golden Gate, those models remain on the device even when the features are disabled.

Reported additional storage use ranges from around 12–18GB, depending on the device and model used. That may be manageable on a larger SSD, but it could make a noticeable difference on a 256GB MacBook Air already running short of space.

Before deployment, we would recommend checking available storage across your estate rather than assuming that disabling AI features will recover the space. Individual usage can be reviewed through the macOS information in the Storage pane of System Settings.

User Facing Features, Changes and Considerations

Refined Liquid Glass

Tahoe introduced Liquid Glass as a substantial visual change to macOS. Golden Gate takes a more measured approach, refining the design rather than replacing it with another new look.

Users will notice improved contrast, clearer separation between interface elements and more consistent window and toolbar designs. Apple has also reduced the number of icons in standard menus, helping to address some of the visual clutter associated with Tahoe.

A particularly useful addition is the ability to adjust the intensity of Liquid Glass. Users who enjoy the translucent appearance can retain it, whilst those who find it distracting can reduce the effect. These controls are available during initial setup and can be changed later in Settings.

For businesses, this is a sensible development. Visual changes can create unnecessary friction when users are trying to get on with familiar tasks, particularly where readability matters more than appearance. Providing a choice allows the interface to suit different preferences without requiring everyone to work in the same way.

Most users should find Golden Gate familiar, especially if they have already moved to Tahoe. Some guidance around the new appearance controls may still be useful, but the overall change is more about making the existing design easier to live with than introducing a new learning curve.

Siri AI

Siri AI is the headline user feature in Golden Gate. Rather than operating primarily as a tool for simple commands, Siri now takes on a broader role in finding information and completing tasks across the operating system.

One important improvement is conversation continuity. Users can ask follow-up questions and refine a request without having to repeat all of the original context. This makes the interaction more natural than treating each instruction as a separate conversation.

Siri can also draw on personal context from sources such as messages, notes, documents, reminders and calendar entries. Instead of remembering a precise filename, a user might ask for the presentation they worked on last Friday or a spreadsheet sent before a particular meeting.

• For business users, the potential applications include:
• Summarising lengthy reports and documents.
• Producing first drafts of emails and other communications.
• Finding information across messages, files and calendar entries.
• Creating reminders and task lists.
• Gathering material held across supported applications.

Siri’s integration into Spotlight also means these capabilities are available through a tool that many Mac users already open throughout the day. There is less need to switch into a separate application simply to ask a question or locate information.

However, businesses should avoid treating AI-generated output as automatically correct. Siri can misunderstand instructions or produce inaccurate summaries, so important communications and decisions still require human review. These tools are best used to reduce the work involved in getting started, not to remove responsibility for the final result.

There are also availability limitations. At the time of the report, Siri AI remains in beta and is available in the UK and US, but not in EU countries. Users need to enable it in Settings and join a waiting list before gaining access. The report notes that this normally takes a few hours, although it can take longer.

Organisations with users in multiple countries should therefore check availability before planning training or introducing workflows that depend on it.

Spotlight & Search

Spotlight has become much more than a way to launch applications. Tahoe expanded its role through actions, clipboard management and automation, and Golden Gate builds on those foundations with changes focused on search reliability and AI integration.

Apple describes a redesigned indexing engine intended to improve accuracy, speed up indexing and make results more consistent across local and cloud storage. For users who have experienced missing or unreliable search results, this could be a welcome improvement.

The most visible addition is the “Search or Ask” experience. Rather than requiring users to decide whether they need a traditional search or an AI interaction, Spotlight can determine how to handle the request and involve Siri AI where appropriate.

In practice, this should mean fewer trips into Finder, fewer application switches and less reliance on knowing exactly where a document was saved. Natural-language requests provide another route to information that might otherwise take several searches to locate.

The business benefit will depend on how well these features work with the applications and storage locations your organisation uses. As with any productivity improvement, testing real workflows is more useful than judging the feature purely by its demonstration.

Apple Intelligence Updates

Beyond Siri, Golden Gate extends Apple Intelligence across writing, visual tasks and everyday organisation.

Writing assistance can help users rewrite, summarise and generate content within a growing range of applications. For teams dealing with lengthy documents or frequent communications, this offers a useful starting point, provided the output is checked for accuracy and suitability.

Visual Intelligence allows users to ask questions about information displayed on screen, including images and documents, and perform actions based on recognised content. Creative tools also gain further image-editing and generation capabilities, which may be useful for marketing, documentation and internal communications.

Apple continues to emphasise on-device processing wherever possible. This is an important consideration for businesses evaluating AI tools, but it should not replace a review of how particular features handle information.

Organisations should make sure existing AI policies cover operating-system features as well as standalone services. Users need clear guidance on what information they can work with, when generated content must be reviewed and which capabilities are appropriate for their role.

Application Updates

Several familiar applications also receive changes in Golden Gate:

• Image Playground: Expanded image-generation styles include photorealistic output, alongside options to modify existing images using descriptions and touchpad gestures. Resource-intensive generation is limited, with additional resources available through iCloud+ plans.

• Safari 27: New features include automatic tab grouping, website update notifications and the ability to use Apple Intelligence to create extensions. Security and WebKit improvements also reach Safari on Tahoe and Sequoia, but the new features do not.

• Photos: Additional Apple Intelligence tools support more advanced touching up, extending and reframing of photographs.

• iPhone Mirroring: The mirroring window can now be resized, allowing supported phone applications to make better use of the Mac’s display.

• Shortcuts: Users can create shortcuts from natural-language requests, with applications such as Calendar and Reminders supporting these automations.

• Notes: Markdown import and export are now supported. This may be useful for developers and other users who exchange formatted text, although it does not mean Notes becomes a Markdown-authoring application.

Individually, these may not determine whether a business should upgrade. Together, they continue the move towards more integrated workflows across Apple’s applications and devices.

Administration Features, Changes and Considerations

Completing the Apple Silicon Transition

For IT teams, the removal of Intel support is Golden Gate’s most important change. Apple’s transition has been gradual, but this release establishes a clear boundary between current hardware and devices that must remain on older macOS versions.

Before deployment, organisations should review:

• Hardware: Identify remaining Intel Macs and establish replacement plans.

• Applications: Check for older software, plug-ins and internal tools that still depend on Intel code.

• Specialist workflows: Assess users whose requirements may make hardware or application migration more complicated.

• Operating systems: Identify devices running older releases that no longer receive security updates.

The report highlights that macOS 14 Sonoma has reached the end of its security-update lifecycle. Devices still running Sonoma should be upgraded to a supported operating system or replaced where an upgrade is not possible.

An Intel Mac being unable to run Golden Gate does not mean it immediately stops working. It does, however, mean businesses need a deliberate plan for its remaining service life rather than allowing it to become an unmanaged exception.

Rosetta 2

Golden Gate is the final macOS release offering broad Rosetta 2 compatibility for Intel applications on Apple Silicon. This gives businesses another reason to review software dependencies now.

Most mainstream publishers already provide native Apple Silicon versions, but older applications, specialist utilities and internal tools may still rely on Rosetta. An application working successfully today should not be taken as proof that it will continue working under future releases.

We would recommend identifying those dependencies, checking vendors’ migration plans and testing native alternatives where available. Addressing them during Golden Gate’s lifecycle is likely to be less disruptive than discovering a critical dependency when the next upgrade is due.

Platform SSO

Platform Single Sign-On continues to develop as Apple’s native approach to integrating organisational identity with macOS. Golden Gate builds on this direction through improvements to onboarding and day-to-day authentication.

For businesses using Microsoft Entra ID, it remains an area worth watching. As support develops, some organisations may be able to simplify their provisioning and login processes without relying on as many additional authentication products.

However, this does not mean existing tools such as Jamf Connect or Mosyle Auth can automatically be replaced. Feature support, licensing and the needs of your users still need to be checked against the solution already in place.

The practical approach is to evaluate Platform SSO within your own environment rather than assuming that greater native integration guarantees equivalent functionality.

Declarative Device Management

Declarative Device Management, or DDM, continues to expand in Golden Gate. Instead of relying entirely on a management server to send instructions and wait for a response, declarative management allows devices to understand the required configuration and maintain it more independently.

This can improve resilience and reduce administrative overhead, particularly for remote users whose devices do not always have a continuous connection to management infrastructure.

However, taking advantage of new capabilities may require changes within your MDM platform. The report highlights Jamf Blueprints as an example, where additional configuration, including Cloud SSO, may be needed before administrators can use the full range of declarative profiles.

Businesses should therefore review both operating system support and their management platform’s implementation. Installing Golden Gate alone will not necessarily enable every new management capability.

Security and Compliance

As AI becomes more deeply integrated into macOS, governance needs to keep pace. Features that can search documents, summarise messages or act within applications may be useful, but they also introduce questions about access to business information.

Areas worth reviewing include:

• Internal AI usage policies and acceptable-use guidance.
• Information classification and handling requirements.
• Document retention policies.
• Regulatory obligations.
• Managed Apple ID controls.

Apple’s emphasis on local processing is reassuring, but organisations should still understand how the features they enable process information. For regulated businesses, that assessment should happen before widespread adoption rather than after users have built those tools into their daily work.

AFP File Sharing Removed

Golden Gate removes the ability to mount AFP file shares. SMB has been Apple’s default file-sharing protocol since Mavericks, and AFP was formally deprecated in macOS 15.5, but some older systems may still rely on it.

This also affects Apple Time Capsule devices and other Time Machine backups using AFP. Businesses with these arrangements will need to move to SMB-based alternatives before upgrading affected users.

Although it is not a headline feature, checking file shares and backup destinations is an important part of avoiding disruption. A successful installation is of limited value if the user can no longer access a required share or complete their backup.
