How to install macOS 15 Sequoia

What you need to check first

  1. Compatibility
    Make sure your Mac is officially supported by macOS 15 Sequoia. Supported models include:
    • iMac (2019 or later)
    • MacBook Air (2020 and later)
    • MacBook Pro (2018 and later)
    • Mac mini (2018 and later)
    • Mac Pro (2019 and later)
    • Mac Studio (all models)

  2. Backup Your Data
    Always back up your important files. Time Machine is a good option, or clone your drive. This protects against data loss if something goes wrong.

  3. Free Space
    Ensure you have enough free disk space. The installer itself requires several gigabytes, plus extra space for temporary files during installation.

  4. Power
    If using a laptop, keep it plugged into power throughout the update.

  5. Software & Firmware Updates
    It’s best to start from the latest version of your current macOS. Some firmware updates may be required before Sequoia can install properly.

Installation Methods

There are a few ways to install Sequoia:

  • Standard upgrade: from your current macOS via Software Update.

  • Clean install: erase the disk & install fresh.

  • Bootable installer: useful for multiple Macs, or offline reinstalls.

  • macOS Recovery: reinstall via recovery mode.

If you want to keep your apps, data, and settings:

  1. Open System Settings (or System Preferences on older macOS versions) → General → Software Update

  2. If Sequoia is available, click Upgrade Now (or “Update Now”)

  3. Read & accept the license agreement

  4. Enter your admin password if required

  5. Wait for the installer to download. Time depends on your internet speed

  6. Once the download finishes, the Mac will prompt you to restart and begin installation

  7. The Mac will reboot several times during the process

  8. After the final restart, follow setup prompts (region, Apple ID, etc.).

If you prefer a clean slate or need to install on multiple Macs:

  1. Download the macOS Sequoia installer
    It will appear as “Install macOS Sequoia” in your Applications folder.

  2. Prepare a USB drive (16 GB or larger)
    Format it as Mac OS Extended (Journaled) or APFS using Disk Utility.

  3. Create the bootable installer
    In Terminal, run:

    sudo /Applications/Install\ macOS\ Sequoia.app/Contents/Resources/createinstallmedia --volume /Volumes/MyUSB

    Replace MyUSB with your USB drive’s name.

  4. Boot from USB

    • Plug in the USB.

    • Restart while holding Option (⌥) on Intel Macs.

    • For Apple Silicon, hold the power button until startup options appear.

    • Choose the USB drive labeled “Install macOS Sequoia.”

  5. Erase / format the internal drive (optional for clean install)
    In macOS Utilities → Disk Utility → Show All Devices → select the internal drive → Erase → format as APFS. Warning: this erases all data.

  6. Run the installer
    Choose “Install macOS,” select your drive, and follow prompts.

  7. Setup after installation completes.

If your Mac won’t boot or you need to reinstall:

  • Intel Macs: hold Command-R at startup.

  • Apple Silicon: hold the power button until startup options appear.

  • Choose “Reinstall macOS,” select your disk, and follow the prompts.

Troubleshooting / Tips

  • Installer doesn’t appear → check Mac compatibility, firmware updates, or free disk space

  • Slow download / installation → use reliable internet and keep plugged into power

  • Errors during install → run Disk Utility → First Aid on your drive

  • Post-install issues → update apps for Sequoia compatibility; some older apps may need patches.
