How to repair a Mac USB port that isn’t always operating

by Yolando B. Adams

USB is an exceptionally common and pretty convenient connection trendy, but it has its annoyances (including placing the cable in the incorrect way spherical) and every so often is going wrong. In this text, we discover the steps you should take if the USB port on a Mac stops working and you are no longer sure why.

Check the relationship

We’ll begin with the easy stuff.

Make certain the cable is well constant into the port. Take it out and put it again in once more to make certain a comfortable connection.

Check there is a good connection at the opposite cease – is the Lightning cable well attached to the iPhone, micro USB nicely attached to the tough force, etc. If the tool is in a case which may be getting within the manner, strive it without the case.

Check for detritus in the port that may be getting in the way. Give it a quick blow or use a can of compressed air. We might advise towards poking around with a straightened paperclip etc, however, a tender cotton-wool bud should be okay. Try the equal on the device stop, too.

Basic solutions
A couple more solutions to strive before we get into troubleshooting.

Restart the Mac
Restart the device (if applicable)
Is the port faulty?
If the fundamentals do not work, we want to establish wherein the fault lies. Try plugging the identical device/cable right into an exclusive USB port on the same Mac (assuming it is got multiple), and into a USB port on a distinctive Mac or a Windows PC.

If it works as quickly as you try a one-of-a-kind port, then the primary port is (probably) faulty: if that is the case, you may want to determine whether or not to manage without that port or get it repaired. If it handiest works when you switch to a distinctive system, you then possibly were given a Mac-huge problem. (In both cases, you must try a number of the fixes similarly down, which may clean matters up and need to affirm wherein the hassle lies.)

If it does not work wherever you plug it in, then the problem probably lies with both the cable or the tool you are plugging into the Mac. We’ll take a look at that subsequent.

Is the cable faulty, or has the tool failed?
These may be trickier to check, and you can want to borrow items from friends or maybe spend a little cash on spares from Amazon, Apple or somewhere else. (If it is a reasonably transportable Mac, you can take it into the Apple Store and they will let you borrow a cable – and you will be in the proper vicinity to get a restore if it proves necessary.)


Keep the whole thing as it changed into – equal port, equal Mac, identical tool – however connect them with an exceptional cable. Does that fix the hassle? If so, the first cable is sort of honestly faulty, and also you simply want to replace it (that is quite cheap, fortunately).Device
If the cable isn’t always the trouble – ie the use of a one-of-a-kind one would not solve the problem – then we need to repeat the test with an extraordinary device at the cease. Try connecting a distinctive iPhone, iPad or USB accent to the Mac the usage of the equal port and cable.

If this fixes matters, then there is a problem with the tool or its port. If it’s a cheap USB stick (that doesn’t have any vital information on it) this is probably true information; however getting an iPhone repaired may be steeply-priced if it is out of guarantee and you haven’t were given AppleCare.

It’s also possible that the device virtually isn’t well suited with your Mac, or that it needs a software/driver update to work with it, so test those factors before rushing into an expensive restore.
