Seeing the preparing macOS 27 stuck at about 5, 15, or 30 minutes message does not always mean the update has failed. The remaining time is only an estimate and may stay unchanged while your Mac continues working.

However, if nothing changes for a long time or your Mac becomes unresponsive, the update may need troubleshooting.

This guide explains how to tell if the update is really stuck and what to do next.

Is macOS 27 Golden Gate Really Stuck on Preparing?

The Preparing stage gets macOS ready before the installation continues. It can take longer than the time shown on the screen, so the remaining time is only an estimate.

For example, your Mac may still show 5 minutes remaining after several minutes have passed. Apple notes that the progress bar can move slowly or remain paused for a long time while macOS updates or installs.

To tell whether the update is really stuck, look at how your Mac is responding. If the progress bar moves or your Mac remains responsive, give it more time. If the screen stays unchanged for a long time and your Mac stops responding normally, you can start troubleshooting.

Why Is Preparing macOS 27 Stuck at About 5, 15, 30 Minutes Remaining

If your Mac stays at about 5, 15, 30 minutes remaining, the time shown on the screen is not necessarily the problem. The Preparing stage can take longer for several reasons.

  • The update needs more time to prepare. macOS may simply need longer than expected before installation can continue.
  • Your Mac is low on storage. The update needs enough free space to download and install macOS. If available storage is too low, the installation may stop progressing.
  • The downloaded update has a problem. An interrupted or incomplete download can prevent the installation from moving forward.
  • The internet connection is unstable. macOS needs a stable internet connection during the update process. Slow or unstable connection may contribute to the problem.
  • Another software or system issue is interfering. If the update repeatedly stops at the same stage, background software or another system problem may be involved. Safe Mode and macOS Recovery can help identify the cause.

How to Fix macOS 27 Stuck on Preparing Screen

If macOS 27 is taking so long to download, you can try the following fixes. Start by giving the download more time to process.

Method 1. Wait and Keep Your Mac Connected to Power

If the Mac is still responding normally, waiting is the safest first step.

Do not restart the Mac simply because the screen still says 5 or 30 minutes. Keep it connected to power and let the preparation continue.

If the screen eventually changes or the installation finishes, you do not need to take any further action.

If the same screen remains for a prolonged period and the Mac becomes unresponsive, continue with the next method.

Method 2. Check Your Mac's Free Storage

If you can still start macOS, check your available storage before trying the update again.

Go to "Apple menu > System Settings > General > Storage". Review the available space and remove unnecessary files or applications if the startup disk is nearly full.

Do not delete files you still need just to create space. If your important files are not backed up, make a backup before making major changes to your storage.

Method 3. Restart Your Mac

If the Preparing screen has stayed unchanged for a long time and the Mac is no longer responding normally, restart it.

Open the Apple menu to select "Restart" if macOS still responds. If the Mac is completely frozen, press and hold the power button until it turns off, then turn it on again.

After startup, check whether macOS loads normally. If it does, go to Settings and check the Golden Gate update again.

Method 4. Try Safe Mode

Safe Mode can help rule out problems caused by software that loads during a normal startup. This is one option to try when installing macOS through Software Update does not work. You can use the following Apple silicon startup process:

  • Shut down your Mac.

  • Press and hold the power button until you see the startup options.

  • Select your startup disk.

  • Hold the Shift key, then select "Continue in Safe Mode".

    continue in safe mode mac
  • Sign in when the login screen appears.

Once the Mac starts in Safe Mode, try Software Update again. If the update works there, the problem may be related to software or startup items that do not load in Safe Mode.

Method 5. Retry the macOS Golden Gate Update

If the Mac starts normally after the previous steps, try downloading the Golden Gate update again through "Apple menu > System Settings > General > Software Update".

If macOS reports that a previously downloaded installer is damaged or cannot be verified, delete the installer and download it again from Apple.

When you see the update stops at the same point again, do not keep repeating the same download-and-retry cycle. Move to Recovery instead.

Method 6. Use macOS Recovery

If Software Update and Safe Mode do not resolve the problem, macOS Recovery provides another way to install macOS.

  • Shut down your Mac.

  • Press and hold the power button until the startup options appear.

  • Select "Options", then click "Continue" to enter macOS Recovery.

  • Select "Reinstall macOS Golden Gate", then click "Continue" and follow the onscreen instructions.

Reinstalling macOS is not the same as erasing your Mac. Do not erase or format the startup disk simply because the update failed.

If your Mac contains important files, check your backups before reinstalling macOS or making other changes to the startup disk.

How to Recover Data After a Failed macOS Golden Gate Update

A failed macOS update can sometimes leave important files deleted or inaccessible. In that case, check your backups first. If there is no available backup, 4DDiG Mac Data Recovery can scan supported storage devices for recoverable files and let you preview the results before recovery.

It supports more than 2,000 file types, including documents, photos, and videos, making it suitable for recovering different types of files that are no longer accessible due to software issues, system crashes, or accidental deletion.
