How to Prepare for MacOS 27 Golden Gate

MacOS 27 Golden Gate has an emphasis on improving performance, with significant enhancements to Spotlight search, mail search, and more. There are also some really nice visual refinements to the Liquid Glass interface and system icons, and there’s even a slider for adjusting the intensity of Liquid Glass. Plus, macOS 27 Golden Gate brings with it a dedicated Siri app, and new Siri AI and Apple Intelligence features, along with many other smaller changes and features throughout the operating system. With all these improvements, it’s easy to see why Mac users are excited about Golden Gate.

The official public release of MacOS 27 Golden Gate is Monday, September 14, and whether you’re jumping in immediately on day one, or waiting a bit, you might want to take a few moments to prepare your Mac for the next major Mac system software upgrade.

How to Prepare a Mac for MacOS 27 Golden Gate

The big things to do are to check for system compatibility of your Mac, update your apps, make sure you have enough free storage available, and to backup your Mac. Once you’ve got those covered, you can update whenever you’d like.

1. Check MacOS 27 Golden Gate System Compatibility

Your first question might be, can your Mac run MacOS 27 Golden Gate? The good news is that MacOS 27 Golden Gate has a pretty broad range of hardware support, but it does drop support for some Macs. The big dividing line is chip architecture.

MacOS 27 Golden Gate will run on any Apple Silicon Mac.

MacOS 27 Golden Gate will NOT run on any Intel Mac.

Only Apple Silicon Macs are supported by MacOS 27, so basically any M-series or A-series processor is a go. If you have an Intel Mac, it will not run MacOS 27.

If you aren’t sure what your Mac is, you can go do the following:

• Go to the  Apple menu and choose “About This Mac”

Look next to “Chip” and if you see anything like Apple M1, Apple M2, Apple M3, Apple M4, Apple M5, Apple M6, A18, Apple anything etc, you have an Apple Silicon Mac. If you see anything related to Intel or Core i5, Core i7, etc, the Mac will not be compatible.

2. Make Sure You Have Sufficient Free Storage

The next requirement is to make sure you have sufficient free storage available to be able to download and install the MacOS 27 Golden Gate update. For this, you’ll need at least 30 GB of free space on your drive to install and update successfully to MacOS 27.

If your Mac is running low on storage space, now would be a good time to perform some cleanup and delete stuff you do not need.

You can check your storage, and where to free things up:

• Go to  Apple menu > System Settings > General > Storage

From there you can see how much storage you have, and what apps and data are taking up space.

3. Update Your Mac Apps

App developers have been updating their apps to be compatible with macOS 27, so updating your apps is a good idea.

• Go to the App Store app, click on your Apple ID / name, then choose “Updates”
• Select to “Update All”

This covers all App Store apps. Just remember that if you have apps obtained directly from a developer, like Chrome or Zoom, you will need to update those independently, often from the developer or within the app itself.

4. Backup the Mac

The most important step: backup your Mac!

Backing up your Mac insures that you can preserve and restore all of your data if something goes wrong, and it even allows you to easily downgrade if you decide MacOS 27 is not for you. Do not skip this step, it’s really important.

If you have not done so yet, you’ll want to read how to set up and use Time Machine on Mac for backups. You will need an external hard drive for that purpose.

5. Ready to Install macOS 27 Golden Gate

You’re now ready to install MacOS 27 Golden Gate!

You can jump right into it as a standard software update the moment it becomes available:

• From  Apple menu, go to System Settings > General > Software Update > Upgrade Now for MacOS 27 Golden Gate

Upgrading to MacOS 27 Golden Gate from Software Update is by far the simplest approach. It will install like any other system update, and reboot your Mac to finish.

If you’d rather perform a clean installation, or use a USB installer drive, those are done separately.

7. Consider Waiting for MacOS 27.1? MacOS 27.2?

Some Mac users wait for the first or second point release update to install a major new operating system version. This is reasonable as well, particularly if you’re waiting for some critical app compatibility, or if what you’re using now works just fine.

With all that said, if you’re currently running macOS Tahoe 26, then you will likely find MacOS 27 Golden Gate to be an upgrade with better performance, and resolutions to frustrating issues with Tahoe including Spotlight not consistently working – that has been resolved in MacOS 27 Golden Gate.

Whether you update to MacOS 27 now, or wait until a later date, or later release version, is entirely up to you.
