Hello, Alex Turner here from MacFix Guide. If your Mac isn’t detecting USB devices, don’t worry, it’s a common issue with several potential solutions. The first thing to try is to unplug the USB device and plug it back in. Sometimes, a simple reconnection can resolve the issue. Also, try connecting the device to a different USB port on your Mac. If you’re using a USB hub, connect the device directly to your Mac to rule out any issues with the hub.
If the above steps don’t work, it’s time to check your Mac’s settings. Open ‘System Information’ by clicking on the Apple menu and selecting ‘About This Mac,’ then ‘System Report.’ In the System Information window, go to ‘USB’ under the ‘Hardware’ section. This will show you a list of connected USB devices. If your device isn’t listed, there might be an issue with the device itself or the USB port.
Another potential solution is to reset the System Management Controller (SMC) and Non-Volatile Random-Access Memory (NVRAM). Resetting the SMC can resolve hardware-related issues, while resetting the NVRAM can fix problems related to system settings. Instructions for resetting these components vary depending on your Mac model, so make sure to follow the appropriate steps.
If none of these solutions work, it’s possible that there’s a software issue causing the problem. Updating your macOS to the latest version can often resolve compatibility issues with USB devices. Additionally, checking for updates to the device’s firmware or drivers might help. If all else fails, it might be time to contact Apple Support or visit an Apple Store for further assistance.
