How to Troubleshoot “USB Port Not Working on Mac” Issue
There might be some issues with hardware and software of your Mac. This troubleshooting guide deals with both the problems.
Solution #1: Check the Hardware
Before you delve into the software labyrinth to find the solution, check the connection of your Mac. You need to take the cable out and insert it again in the USB port. Many users connect cables casually and then wait till eternity for their iPhone to appear in iTunes. Remember, proper insertion is necessary.
Next, also check the connection at another end, i.e., a lightning cable is securely connected to your iPhone or iPad. If you are trying to connect your external hard drive to Mac, ensure that micro USB is accurately attached to the hard disk.
If you are using a clumsy case to protect your iPhone or iPad, remove it and then connect your device to the Mac.
Even if you are sitting in an air-tight cubicle, your Mac is exposed to some dirt or grime. Over a period, debris gathers in or around the USB port of your Mac. This can prevent your USB device from connecting to the Mac. To get rid of this rubbish, use a high-quality blower or a soft cotton bud.
If your Mac has multiple USB ports, you can use all one after another. Remove your USB device and insert the cable in another port. If your device connects successfully in another port, there is some problem with a specific port on your Mac. In case your Mac has only one port, you can connect your device to another Mac or Windows computer.
Your Mac requires the attention of an expert if one or all ports are defective. If you can manage with other ports (forget that faulty one), go ahead; otherwise, take your Mac to the nearest Apple Service Center to get the port/s fixed.
Solution #3: Defective Cable or Device
When your device fails to connect to the Windows system as well, there might be some issues with cable or device itself.
A defective cable or a failed device is a more severe situation as you might need to spend some bucks. However, you can take your portable Mac to the Apple Service Center and request them to lend you a cable, so that you can sync your device to your Mac. If this works, you have to change the cable.
Buying a new cable may not be a big deal, but if there is an issue with your device, getting it repaired can be a costly affair for any consumer. To check the device efficiency, you need to keep the same cable and same port, but change your iPhone/iPad or a USB device.
Solution #4: Reset SMC/ PRAM/NVRM
Once you follow the above methods, you will get a fair idea where the problem is. In case your cable and device are in good shape, it is your Mac that needs repair. But before you take your laptop to the Apple Store, you can follow three solutions to get the issue fixed.
Solution #5: Software Update
Updating your macOS is the best way to solve multiple issues. When your macOS is updated, you can check the USB port’s efficiency on your laptop.
Solution #6: Uninstall Malfunctioning Apps
If everything is OK and still USB ports are not working on your MacBook Pro or iMac, there can be some issues with some conflicting apps. Many users download apps from unknown sources, which may contain malware.
That’s all friends!
