If some USB devices work on the Mac, but another USB device does not work, consider that the device may be incompatible with that particular Mac, the USB device may be failing or have failed, or, in some situations, the USB device may need specific hardware drivers from the manufacturer in order to work properly (typically the case with special use devices, high-end scanners, etc).If liquid has splashed on the Mac or the MacBook has contacted water, you will need to take immediate steps to power down and dry out the Mac for a chance to prevent permanent damage – liquid contact can destroy a Mac rather quickly, or damage certain hardware functionality, like USB.If a single USB port has failed but other USB ports are continuing to work on the Mac, even after an SMC reset, there may be an issue with that specific hardware USB port – you can either avoid using that USB port and instead use a USB hub for one of the other functioning ports, or you can have Apple run a hardware diagnostics test on the machine to determine if there is any hardware failure.Other Considerations for USB Not Working on a Mac And yes, this can apply to any and all Macs, whether a MacBook Pro, MacBook Air, MacBook, iMac, Mac Mini, or Mac Pro. If multiple USB devices are not working on a particular port, or all ports, then it’s obviously less likely to be a device issue, and more likely to be related to the Mac itself. The easiest way to determine if the USB device itself is the problem versus the Mac USB port, is to try and use at least two different USB devices and switch their ports. This is particularly true with cheap low quality USB devices and cables. If after all this we can look at running in depth hardware diagnostics.įirst and foremost, keep in mind that sometimes a USB device itself can fail, which may have nothing to do with the Mac itself. I’d start over, go through all of this to see if you can reset. I’m wondering if the keyboard problems have prevented complete resets.

This will tell you if it is a software issue. Next start up in Safe Mode by holding down the Shift key on start up. Now you can independently test both the keyboard and mouse. Start with disconnecting the mouse and plug it straight into a USB port.
