Here’s how to cross-check if your Mac is compatible with macOS Sequoia:

  1. Click the Apple Icon.
  2. Select About This Mac.
  3. Check your MacBook model and year.
  4. Visit Apple’s Sequoia compatibility list and see if your device type is listed.

2. Check internet connection

A stable internet connection is essential to download macOS Sequoia. Sometimes your connection can drop without you even noticing and be behind the preparing macOS Sequoia stuck error. Both wireless and wired connections can suddenly lose connection. Here’s how to check your connection is stable before you continue…

  1. Open System Settings.
  2. Go to Wi-Fi.
  3. Check that there is a Green Dot next to Connected.
  4. If you use a wired connection, check that all cables are securely plugged in.

3. Free up and optimize disk space

Another common culprit, second to poor internet connection, is insufficient disk space. Not having enough free space on your drive can cause macOS Sequoia to get stuck. To make room, we recommend checking your Storage and following the custom Recommendations to reclaim space and let macOS Sequoia install smoothly.

 

Here’s how to find your Storage Recommendations to free up space:

  1. Open System Settings.
  2. Go to General > Storage.

In Storage, you’ll see a chart that represents how much space is being used up and how much is free. If there's not enough for macOS Sequoia and you need to make more room, check out the personalised Recommendations and follow the on-screen instructions to claw back more disk space.
Step 2. Look for your tailored Recommendations to help optimize your disk space

If you’re unsure how much space macOS takes up, it’s quite a bit! For exact details and other installation requirements, our supporting blog has plenty of helpful info.

4. Check Apple servers

Sometimes macOS installation issues come from Apple’s servers, not your Mac or internet connection. To check for any outages on their end, we recommend visiting Apple’s System Status page.

Open Apple’s system Status page and look for macOS Software. If it’s green then there is no Apple Serve issue, but if you are facing macOS Sequoia installation issues, then the problem is from something else.
On the System Status page, look for macOS Software and check its green

Here’s how to reinstall macOS using Recovery Mode:

  1. Go to the Apple Icon and choose Shut down.
  2. Turn it on and immediately press and hold Command + R.
  3. Release the keys when you see the Apple logo.

6. Reset PRAM and SMC

Resetting your Mac’s PRAM and SMC are two more quick fixes that are known to help resolve software glitches known to prevent important downloads from progressing as usual.

Reset PRAM

We understand that the thought of resetting PRAM might sound complicated, but in our experience, it's a fairly straightforward way of clearing all your system settings and helping fix weird software glitches. It’ll only take a few seconds to reset your PRAM and hopefully get your macOS Sequoia download back on track.

 

Here’s how to correctly reset PRAM on your Mac to help fix macOS Sequoia issues:

  1. Shut down your Mac.
  2. Turn it back on and immediately press and hold Command + Option + P + R.

Reset SMC

If your Mac feels sluggish and macOS Sequoia updates are still not progressing, we recommend trying an SMC reset. It'll help clear out any hardware-related nuisances, like your battery or fans, preventing important updates.

 

Here’s how to safely reset SMC in case your device needs troubleshooting:

  1. Power down your Mac.
  2. Hold Shift + Control + Option along with the power button for 10 seconds.
  3. Release all keys and turn your Mac back on.

7. Download macOS Sequoia from App Store

You can also try to download macOS Sequoia directly from the App Store for a clean copy. This is helpful if the usual Software Update in Settings isn’t working.

 

Here’s how to find macOS ready to download via the App Store:

  1. Click on the App Store icon in your Dock.
  2. Search for macOS Sequoia.
  3. Click the Get button to initiate download.
You can also try to download macOS Sequoia from the App Store. This might help fix any stuck issues you are facing when trying to download the OS through the Software Updates section in System Settings.

An extra help from our team: 

 

Changed your mind about macOS Sequoia now? There’s no need to worry whether you can go back to Sonoma from Sequoia or not, as our attached blog has all the advice and preparation steps to guide you through the macOS Software downgrade.

 

However, we would not recommend downgrading your software, as not having the latest OS can affect your Mac’s stability in the long run, as new updates resolve glitches and security patches; downgrading your software could leave you vulnerable to malware or threats.

8. Install macOS Sequoia from Terminal

Are you still having issues with your Sequoia installation? In case downloading a clean version of the OS from the App Store didn't resolve your stuck problem, it might be time to try some more advanced options like Terminal commands. Terminal is usually for more advanced Mac users, but you can follow our steps below to help make the process more straightforward to follow.

 

Here's how to install macOS Sequoia from Terminal:

  1. In Finder, go to Applications > Utilities.
  2. Click on Terminal to open it.
  3. Type in the following command into Terminal: softwareupdate-- list-full-installers.
  4. Press Enter.  
  5. Note the version number of the latest macOS Sequoia you want to download.
  6. Then run the following command (replacing version_number with the one you want): softwareupdate-- fetch-full-installer-- full-installer-version version_number.
  7. Wait for macOS Sequoia to download.
  8. Look for the installer in Applications and run it to update your Mac.
To use Terminal to try and download macOS Sequoia, begin by going to Finder > Applications > Utilities, to open Terminal. Then type softwareupdate --list-full-installers and press Enter. Find the version number of the macOS Sequoia you want, then run softwareupdate --fetch-full-installer --full-installer-version version_number (replacing version_number). Wait for the download to finish, then open the installer in Applications to update your Mac.
Open Terminal, run softwareupdate --list-full-installers, then use softwareupdate --fetch-full-installer --full-installer-version version_number to download Sequoia

9. Get macOS Sequoia directly from server

If you can’t find macOS Sequoia in Terminal or the App Store download source is also not working, you can try an alternative solution—going to Mr Macintosh's database website that has downloadable pkg files for all the versions of macOS (resources pulled from trusted Apple servers). This should allow you to download a clean, compatible version of macOS Sequoia.

 

Here’s how to get macOS Sequoia pkg files to download:

  1. Go to the Mr Macintosh database and click on the InstallAssistant.pkg next to the version of macOS Sequoia you want to download.
  2. Once downloaded, open the pkg file and save it in your Applications.

The Mr Macintosh database houses all of these helpful pkg files conveniently for you to choose which version you want to try and download.

10. Install macOS Sequoia using the bootable installer
