Macbook USB Port problem – common issues and solution to fix
There are many causes and things behind the problem and related issue that the USB Port does not work suddenly on your MacBook, Macbook Pro, Macbook Air and iMac. Look at our following solution to fix.
What should you do if one day, the USB Port does not work suddenly? Firstly, I want to highlight 2 circumstances that make you attribute the causes to USB Port problem instead of Broken Flash Drives (USB, External HDD) or Software issues.
- To make sure the External Drive such as USB and external HDD is not broken, you should reattempt to connect them via different available USB Ports on your Mac or Other PC.
- Be aware of that USB or External HDD in NTFS format is not supported by Mac OS X 10.10 yet. Therefore, before supposing Mac USB Port does not work, you should read our another share about Enable NTFS Supporting in Mac OS X.
How to check if there are some problems with USB Port on Mac?
You can use other USBs (Be careful with NTFS Format one as I mentioned above) which are working on another Mac, then plug into your Mac. At the results, if the USB does not work on only one USB Port, that particular Port is broken physically, and you are still able to use the rest as usual.
In another hand, if the tested USBs do not work on all USB Ports, you might solve the problem by following solution.
Repair USB Port on MacBook, Macbook pro, Macbook Air, Mac mini and iMac
There is only one way to fix USB Port issue on your Mac devices: reset SMC.
In deed, if you are sure that All USB Ports on Mac devices (MacBook Pro, MacBook Air, MacBook, iMac, Mac Mini, or Mac Pro) do not work instead of they used to work fine, reset SMC probably help to get rid of the issue.
