Are you frustrated with your Macally M4 hub not working correctly with your Mac Mini or MacBook? You’re not alone. Many users report issues such as overheating, connection drops, power failures, and compatibility headaches.
In this guide, we’ll walk you through the top 10 fixes for Macally M4 hub problems, so you can get your device working smoothly again—and avoid buying the wrong hub next time.
Check USB-C Port Compatibility
Problem: Your MacBook or Mac Mini doesn’t detect the Macally M4 hub.
Solution:
Make sure you’re using a Thunderbolt 3/4 or full-featured USB-C port. The M4 hub needs data and power delivery support—some ports (especially on monitors or third-party docks) only provide charging.
🔧 Fix: Try plugging the hub into a primary USB-C port directly on your Mac.
Reset the SMC (System Management Controller)
Problem: Charging or power delivery via the hub is inconsistent.
Solution:
Resetting your Mac’s SMC can often resolve charging and hardware recognition issues.
🔧 Fix Steps:
- Shut down your Mac.
- Hold Shift + Control + Option + Power for 10 seconds.
- Release and restart your Mac.
Run a macOS Update
Problem: Macally hub not working after macOS update.
Solution:
macOS updates can introduce compatibility issues. Make sure your OS is up to date, or roll back if the issue started after a recent update.
🔧 Fix: Go to System Settings > General > Software Update and install any available patches.
Install/Update Macally M4 Hub Drivers (If Available)
Problem: Hub functions like HDMI, Ethernet, or SD card not working.
Solution:
While the Macally M4 hub is generally plug-and-play, driver updates may be available for specific functionalities.
🔧 Fix:
- Visit Macally’s Support Page for driver downloads.
- Reboot your system after installation.
Use a Different Cable
Problem: Hub disconnects randomly.
Solution:
The included USB-C cable might be faulty. A low-quality cable can cause signal drops or overheating.
🔧 Fix: Replace it with a Thunderbolt 3-certified cable with at least 100W PD support.
Prevent Overheating
Problem: Macally hub gets too hot during use.
Solution:
Overheating may be due to power strain or lack of ventilation.
🔧 Fix Tips:
- Avoid stacking devices on top of the hub.
- Use a laptop stand to improve airflow.
- Disconnect unused peripherals.
Avoid Power Overload
Problem: USB devices disconnect randomly.
Solution:
The hub may not supply enough power to multiple devices at once.
🔧 Fix:
- Use a powered USB-C hub or add a separate power adapter.
- Disconnect high-power devices like HDDs during other operations.
Disable Sleep Mode Conflicts
Problem: Hub disconnects when your Mac goes to sleep.
Solution:
Sleep mode can cause USB devices to power down improperly.
🔧 Fix:
- Go to System Settings > Battery > Options.
- Set “Prevent automatic sleeping” while connected to power.
Try Safe Mode or New User Profile
Problem: Macally hub only works intermittently.
Solution:
Corrupted user settings or extensions can interfere with USB hubs.
🔧 Fix:
- Reboot into Safe Mode (Hold Shift during boot).
- Test the hub.
- Create a new user profile and check if the issue persists.
Test with a Different Device
Problem: You’ve tried everything, and it still doesn’t work.
Solution:
Eliminate the possibility of a faulty hub.
🔧 Fix:
Test your Macally M4 hub on another Mac or USB-C device. If it fails there too, it’s likely a hardware issue.
