5 hidden macOS 27 "Golden Gate" features you're probably missing

Full text

Apple’s macOS 27 release — dubbed ‘Golden Gate’ by the company — is packed with new features, despite Apple saying that this year was more of an evolution than revolution. There are plenty of additions that have got tongues wagging and pens scribbling across the internet.

Yet for every Siri app and Liquid Glass tweak , there are many more upgrades that people are barely talking about. That means that if you don’t dig below the surface, you might miss some of the interesting new ways you can use your Mac once you’ve downloaded and installed macOS 27 .

Here, we’ll run through five of our favorite little-known inclusions in the macOS Golden Gate beta . Get to grips with all of them and you’ll have fresh ways to use your Mac on a daily basis.

Visual Intelligence

You’d point your iPhone at an object, press the Camera Control , and Visual Intelligence would identify the object or pull out details from an event flyer and add them to your calendar. Now, similar powers can be harnessed on your Mac.

But you might be asking how this will work on a Mac, seeing as you can’t just go up to something and take a picture of it with your laptop. Fortunately, Apple has adapted Visual Intelligence to macOS 27 in a handy new way.

Much like when you take a screenshot, you can drag a box over part of your screen using your mouse. When you let go, you can ask Visual Intelligence to help you with what you have selected. You can ask Siri AI a question about the image and it will respond. You can then go back and forth with the chatbot if you need more information.

If you highlight an event, you can add it to your calendar. Even better, if you use Visual Intelligence on a festival schedule with multiple acts playing at different times, for instance, you can add as many or as few to your calendar as you want, all saved as separate entries with relevant info like the band that’s playing and the stage that you’ll find them on.

This is one of my favorite features in macOS 27 as it’s not only useful, but highly flexible and intelligent. Visual Intelligence is able to understand many different inputs and the contexts surrounding them, turning Siri into much more of the powerful assistant that it was always meant to be.

Automatic password strengthening in Passwords

(Image credit: Future) The best password managers often alert you if your logins stored in the app are weak or compromised, but that usually means updating them to stronger alternatives yourself.

If that requires manually visiting affected websites and changing your login details by hand dozens or even hundreds of times, the task can feel incredibly daunting. Faced with that kind of situation, many people likely just give up, preferring to stick with their untrustworthy passwords rather than go through the hassle of changing them all one by one.

That’s an obvious security risk, and it’s one that macOS 27 has attempted to put right. Although the following change hasn’t had much airtime since the feature was announced at Apple’s Worldwide Developers Conference (WWDC) in June, I feel like it could be one of the most important features in the new operating system.

In macOS 27, all you need to do is ask Apple’s Passwords app to fix your dodgy passwords for you. Just one click and it’ll get to work visiting affected websites and updating your logins without you needing to lift a finger.

It’s a great example of how useful AI agents can be, all backed up by Apple’s well-known security and privacy credentials.

Natural language in Calendar

(Image credit: Future) How many times have you opened the Calendar app on your Mac and tried to create a new event with a phrase like “Movie night with James tomorrow at 8pm at home,” only to find none of the details — such as the time or the place — are properly added to the event?

It’s been a recurring problem for years, and a frustrating one, too, as Apple fans have watched other apps race ahead with similar features while Calendar lags behind.

Now, that’s been improved. Changes in macOS 27 mean that you just need to enter an event using the type of natural language that you’d use in an everyday conversation. Any details that Calendar can pick up on — like a person, place, time or date — will turn gray. Click them and select the suggested detail and they’ll be properly added. This feature understands your context, too, such as where your home is located.

Sure, similar features have been present in rival calendar apps for years, and that could explain why Apple’s Calendar update hasn’t exactly lit the world on fire in the weeks and months since it was announced.

But having this feature is nonetheless an excellent addition for users of the Calendar app. The more naturally you can use your apps, the more effortless they become, allowing you to quickly be done with them so you can get on with what matters in your day. This natural language upgrade for the Calendar app lets you do exactly that.

App resizing in iPhone Mirroring

(Image credit: Apple) Of all the clever new features announced last year as part of macOS Sequoia in 2024, iPhone Mirroring was one of the more intriguing. As the name suggests, it mirrors your iPhone onto your Mac’s screen, bringing up a software view of your device where you can open apps, type messages, and basically use everything on your iPhone through the Mac sitting in front of you.

But there was one annoying quirk with this system: you couldn’t resize the iPhone window to use different aspect ratios. That meant any apps you opened on the virtual iPhone were limited in size and failed to make use of your Mac display’s larger proportions.

Thankfully, Apple has fixed that up in macOS 27. Instead of being stuck with the unchanging iPhone window of the past, macOS 27 now lets you drag the on-screen iPhone and change its dimensions as required.

You can now make the iPhone window wider or taller and the content inside the app will automatically adapt. It’s far better than what we had before.

So, if you’d given iPhone Mirroring a try before but were put off by the tiny window you had to work with, macOS 27 could make using your iPhone on your Mac a little more comfortable.

Improved support for ultra-wide displays

(Image credit: HP) Before macOS 27, using an ultra-wide display with your Mac could be a downright pain. Many ultra-wide resolutions were not supported natively in macOS, meaning you had to settle for something that wasn’t quite right for your display, which could in turn negatively affect your macOS experience.

And when competing operating systems like Windows could support ultra-wide monitors in a more comprehensive way, the frustration for Mac users was understandable.

Worse, if you ever unplugged your monitor and then plugged it in again, macOS would forget your previous display settings, forcing you to set up your ultra-wide monitor as needed every single time. If you relied on one of the best MacBooks as your daily driver and you frequently disconnected it from your desk display, this was a regular irritation.

In macOS 27, though, that’s finally a thing of the past. You’ll now be able to run an ultra-wide monitor up to 5K resolution and up to 120Hz refresh rate, meaning far more high-end displays will now work with macOS 27 without a hitch.

And Apple has fixed the disconnection issue so that hooking up your monitor no longer requires you to dial in your settings every time. Instead, macOS remembers your preferences so that no manual adjustments are needed.

That makes this a seemingly small change on the surface, but one that will be appreciated by anyone who owns an ultra-wide monitor and has long struggled with the limitations of macOS.
