How to download and install macOS Sequoia beta

Apple revealed the latest macOS 15 Sequoia at its Worldwide Developers Conference (WWDC) on June 10, 2024.

This upgrade is full of exciting new features, such as iPhone Mirroring which enables you to control your iPhone from macOS, the new Passwords app that allows you to access passwords and manage credentials in one place, and the great updates to Safari.

But the most intriguing part is the introduction of Apple Intelligence, which leverages the power of generative AI and Apple Silicon to simplify and accelerate Mac users' everyday tasks.

If you can't wait to test it out, you can now download the macOS Sequoia beta program directly from Apple with or without a developer account. We'll cover three different methods to do this.

Since macOS Sequoia beta is not fully polished, I'd suggest you not install it as your main system but play with it on a separate volume or a spare external drive.

Should you install macOS Sequoia beta?

Beta software, by nature, is not as stable and reliable as a public release. It may have bugs, app compatibility issues, performance problems, and other unexpected troubles. However, if you're eager to explore its new functionalities, you can still get macOS Sequoia beta, as long as you make preparations.

Here are a few things you should do before downloading or installing macOS Sequoia beta:

  • Back up your Mac with Time Machine so that you can go back to a previous version without losing data.
  • Avoid installing macOS Sequoia beta on the main volume of your work machine.
  • Clear your Mac to make space for macOS Sequoia.

Not having enough space is a common issue that causes the macOS 15 Sequoia installation to fail. If you want to avoid it, you can use iBoysoft DiskGeeker to analyze your internal hard drive and remove unnecessary files. This disk cleaner can find all files on your Mac and sort them by size, enabling you to quickly spot the space hogs and get rid of them for good.

How to install macOS Sequoia Beta?

Depending on your use case, you can install macOS Sequoia on your system partition, a separate volume, or an external drive.

① Install macOS Sequoia as your main system

If you're testing macOS Sequoia on a less important Mac, have backed up your Mac, or aren't afraid of any issues that may impact this Mac, you can run the macOS Sequoia developer beta as your main system. Simply download it from Software Update, as we mentioned above. The installer will then automatically install itself on your system partition.

② Install macOS Sequoia on a separate volume

On macOS High Sierra or later, the default format for Mac's startup disk is APFS. This file system allows for space sharing between different volumes, as opposed to the concept of partitions, which are independent logical storage areas.

Therefore, if you want to be cautious and separate macOS Sequoia from the stable macOS version, you can create a second APFS volume and install macOS Sequoia on it. Make sure your Mac has sufficient space to accommodate macOS Sequoia.

  1. Open Disk Utility.
  2. Select the APFS container and click the ( + ) button above Volume.How to create a seperate APFS volume for macOS Sequoia
  3. Name the volume and click Add.
  4. Run the Install macOS 15 beta.app installer from your Applications folder.
  5. Follow the onscreen instructions to install it onto the newly created APFS volume.
  6. Change your Mac startup disk to use macOS 15.

It's worth mentioning that some use the words volume and partition interchangeably. If that's you and you're looking to install macOS Sequoia on a different partition, the above steps would suffice.

④ Install macOS Sequoia on an external drive

The safest method is to run macOS Sequoia from an external drive that's big enough for its installation files, future OS updates, and your personal data and all the programs to work properly. Make sure you choose an SSD, because Apple's APFS is optimized for it.

  1. Connect the external drive to your Mac.
  2. Open Disk Utility.
  3. Click View > Show All Devices.
  4. Select the top-level physical disk of your external drive and click Erase.How to format external drive for macOS Sequoia
  5. Name it.
  6. Choose APFS as the format.
  7. Keep GUID Partition Map as the scheme.
  8. Click Erase.
  9. After the erase process is complete, run the macOS 15 installer from your Applications folder.
  10. Follow its instructions and select your external drive as the destination.
  11. Boot your Mac from the external drive.
