macOS Tahoe is Apple’s newest update for the Mac lineup, bringing fresh features, design tweaks, and better integration with iOS. But like many major macOS releases, early adopters are already running into annoying bugs.
If you’ve just upgraded and found yourself stuck with Finder glitches, external drive issues, or system slowdowns, you’re not alone. I’ve collected the most common Tahoe problems being discussed online and some practical fixes/workarounds you can try today.
1. Finder Freezes or Becomes Unresponsive
Many users report Finder suddenly freezing when navigating large folders.
Fix:
- Try relaunching Finder via Force Quit (Apple menu → Force Quit → Finder → Relaunch).
- If the issue repeats, clear Finder preferences:
rm ~/Library/Preferences/com.apple.finder.plist
killall Finder

2. Apps Not Opening Properly
Some apps either don’t launch or close immediately on Tahoe.
Fix:
- Check if the app is compatible with macOS Sequoia at RoaringApps compatibility database.
- Update the app from the Mac App Store or the developer’s site.
- For unsigned apps, go to System Settings → Privacy & Security and allow them manually.

3. Wi-Fi Connection Drops Frequently
Another common Tahoe bug is Wi-Fi cutting out randomly.
Fix:
- Delete old Wi-Fi preferences:
sudo rm /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
sudo rm /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
sudo rm /Library/Preferences/SystemConfiguration/preferences.plist
- Restart your Mac and reconnect to Wi-Fi.
- If the issue persists, reset your router and check Apple’s Wi-Fi recommendations.

4. Slow Performance After Update
Some Macs feel slower after updating to Tahoe, even with enough memory.
Fix:
- Reindex Spotlight search by going to System Settings → Siri & Spotlight → Spotlight Privacy, add your disk, then remove it.
- Reset SMC and PRAM (Intel Macs only).
- Monitor background processes with Activity Monitor.

5. External Monitors Not Detected
Users with dual-monitor setups complain their displays aren’t detected.
Fix:
- Go to System Settings → Displays → Detect Displays.
- Use the proper cable/adapter (see Apple’s guide on external displays).
- If nothing works, reset NVRAM/PRAM.

Final Thoughts

Many of the frustrations users are seeing in macOS Tahoe feel familiar if you’ve been following Apple’s recent update cycle—especially when you look back at the feature changes introduced in what’s new in macOS Sonoma and its coolest upgrades, which laid the groundwork for many of today’s system-level behaviors.
