Troubleshooting macOS Sequoia 15: Navigating the Upgrade
Common Issues and Solutions
- Installation Problems:
- Error downloading macOS Sequoia: If you encounter this error, try temporarily turning off “Find My Mac” in System Preferences. If that doesn’t work, consider using Apple Configurator 2 on another Mac to revive or restore your device.
- Stuck progress bar or no progress bar during installation: Boot into Recovery Mode (hold Command + R while restarting) and run Disk Utility’s First Aid on your startup disk.
- Connectivity Issues:
- Wi-Fi or Bluetooth not working: Try toggling the “Private Wi-Fi Address” option in your network settings. If that doesn’t solve it, reboot into Recovery Mode and perform multiple disk repairs using Disk Utility’s SOS Repair function.

Preparing for macOS Sequoia Installation
Getting ready for macOS Sequoia takes a few key steps. You’ll need to check if your Mac can run it and back up your data. Then you’ll learn about different ways to install the update.
Ensuring Compatibility and Backup
First, make sure your Mac can run Sequoia. Check Apple’s website for a list of supported models. This includes recent MacBook Air, MacBook Pro, iMac, Mac mini, Mac Pro, and Mac Studio devices.
Next, back up your data. Use Time Machine or another backup tool. This keeps your files safe in case something goes wrong during the update.
Update your current macOS to the latest version. Open System Settings and click Software Update. Install any available updates before moving to Sequoia.
Check your Mac’s storage space. You’ll need at least 20GB free for the update. Delete old files or move them to an external drive if needed.
Understanding Installation Methods
There are two main ways to install macOS Sequoia. The easiest is through Software Update in System Settings. Your Mac will download and install the update automatically.
For a fresh start, you can do a clean install. This erases your Mac and installs Sequoia from scratch. You’ll need to make a bootable USB drive with the Sequoia installer.
Some Macs may need a firmware update before installing Sequoia. Your Mac will handle this on its own during the update process.
If you’re an Apple Beta Tester, you might get early access to Sequoia. Sign up on Apple’s website to join the program.
Troubleshooting Common macOS Sequoia Issues
macOS Sequoia can have problems that affect system speed, apps, and connections. Here are ways to fix these issues.
Addressing System Performance
Slow Macs with Sequoia often have memory leaks. Check Activity Monitor to spot apps using too much RAM. Close these apps or restart your Mac to free up memory.
If your Mac still runs slow, try Low Power mode. Go to System Settings > Battery and turn it on. This can help save battery life too.
Clear out junk files to free up disk space. Remove old downloads, temp files, and app caches. More free space can boost system speed.
Updating to the latest version of Sequoia may fix bugs causing slowdowns. Go to System Settings > General > Software Update to check for new versions.
Resolving Application Conflicts and Failures
Apps crashing in Sequoia is a common issue. First, make sure your apps are up to date. Many developers release patches for Sequoia compatibility.
If an app keeps crashing, try deleting and reinstalling it. This can fix corrupted files causing the crashes.
Some third-party apps may not work with Sequoia yet. Check the app’s website or contact the developer to see if they have a Sequoia-compatible version.
For system apps like Siri or Control Center, try resetting them in System Settings. If that doesn’t work, you may need to reinstall macOS Sequoia.
Reestablishing Connectivity
Bluetooth issues can occur in Sequoia. To fix this, go to System Settings > Bluetooth. Turn Bluetooth off, wait 10 seconds, then turn it back on.
If Wi-Fi won’t connect, forget the network in System Settings > Wi-Fi. Then reconnect by entering the password again.
Screen sharing and iPhone mirroring may fail. Ensure both devices are on the same Wi-Fi network and signed in to the same Apple ID.
For AirPods not connecting, put them in the case. Close the lid, wait 15 seconds, then try pairing again.
