There is probably a Mac in your studio that has been doing its job without complaint for the last five or six years. An Intel iMac, maybe. Reliable, fast enough, no reason to replace it. Until now there has been no urgent reason to. macOS 27 Golden Gate, announced at WWDC in June and due for release in September 2026, is that reason.
This is the first version of macOS that will not install on Intel Macs at all. It is also the last version to fully support apps that were built for Intel. Both of those things have real, practical implications for how you run your studio or practice over the next twelve months.
What Golden Gate is
Golden Gate is the next major macOS release. It was announced at WWDC on 8 June 2026 and is expected to ship in September, following the standard Apple release cadence. The headline feature is a completely redesigned Siri, powered by Apple Intelligence, that behaves more like a capable AI assistant than the voice assistant people gave up on years ago. It can search your emails and messages to find things, answer questions using up-to-date web knowledge, take action inside apps and read what is on your screen.
Beyond Siri, Apple Intelligence runs across the whole operating system: smarter writing tools, AI photo editing in Photos, Safari that organises your tabs automatically and monitors sites for changes, and shortcuts that you can create just by describing what you want. There are also design refinements, performance improvements and updated parental controls.
For most businesses, the AI features are not the urgent item. The hardware question is.
The Intel Mac cut-off
macOS 27 Golden Gate is Apple silicon only. If a Mac does not have an M-series chip, it will not run Golden Gate. Full stop.
Intel Macs can continue running macOS 26 Tahoe, and Apple will supply security patches for them for some time. But Tahoe is the end of the road for those machines in terms of new operating system versions. They will fall steadily further behind the current OS, and at some point security updates will stop arriving too.
If your business still has Intel Macs in active use, this is the signal to plan replacements. Not urgently, not tomorrow, but with a real timeline, because "we will deal with it eventually" tends to stretch until a machine dies mid-project.
Which Macs can run Golden Gate? Any Mac with Apple silicon: M1, M2, M3 or M4 chip. That covers MacBook Air, MacBook Pro, Mac mini, Mac Studio and Mac Pro models from late 2020 onwards. If you are not sure what your team is running, we can audit your estate.
The hidden deadline: Rosetta 2
This one catches people out. Rosetta 2 is the translation layer that lets Apple silicon Macs run apps originally built for Intel chips. It has been quietly keeping older software working since 2020.
Golden Gate still includes full Rosetta 2 support. The macOS release after Golden Gate is expected to remove it.
That means any plugin, tool or application that has not been updated to run natively on Apple silicon will stop working when your team upgrades past Golden Gate. Adobe creative tools, specialist rendering plugins, audio software, industry-specific utilities: if any of these are still Intel builds, your window to get native alternatives in place is now.
This is worth checking before September, not after. A two-minute audit of your installed applications (Activity Monitor shows Intel versus Apple silicon processes) will tell you whether you have a problem. For studios running unusual or legacy tools, it is worth running that check now rather than discovering the gap during a deadline week.
If you are fully on Apple silicon
You can upgrade to Golden Gate when it ships. Check your plugin and app library before you do, particularly anything specialist or from smaller developers. A quick review takes less time than a broken render at the wrong moment.
If you have Intel Macs still in use
Those machines stay on Tahoe for now. Plan a replacement timeline over the next six to twelve months. You have time to do this properly, but waiting another year or two means running security-update-only machines.
The AI features worth noting
For creative businesses, a few of the Golden Gate AI additions are genuinely useful rather than just impressive in a keynote.
Photos editing gets meaningful new tools: Clean Up is better at removing objects, Reframe lets you change the composition of an image and Extend uses AI to fill out a cropped shot. For studios producing assets for client presentations, these are practical time-savers.
Siri and writing tools work across the whole OS. Writing with AI assistance, summarising long documents and getting quick answers without switching to a browser will become part of daily Mac use in the way copy and paste is now.
Safari's Notify Me feature monitors a webpage and alerts you when it changes. Useful if anyone on your team is tracking planning portal updates, client briefs or supplier pricing pages.
The AI features that require newer hardware (custom Siri voices, some on-device dictation improvements) need an M3 chip or newer. First-generation Apple silicon Macs get most of the features but not all.
What this means day to day
For studios and practices on a managed plan, the practical answer is that most of this is already in hand. We track the hardware in your estate, flag machines approaching end-of-life and test OS updates before pushing them to your team. Golden Gate will go through the same process: staged rollout, compatibility checks and a decision made with your timeline in mind, not Apple's.
The one thing worth doing yourself, regardless of whether you are on a managed plan, is checking for Intel apps. If you have any critical software that has not been updated since before 2021, raise it with whoever manages your IT.
Not sure where your Mac estate stands? We can run an audit of your hardware and installed software against Golden Gate compatibility. It takes about twenty minutes and gives you a clear picture before the autumn release.
Golden Gate is a significant release. The Intel Mac cut-off is the biggest infrastructure decision Apple has forced in years, and the Rosetta 2 deadline means that even businesses already on Apple silicon have planning to do. September is closer than it looks.
