If your Mac keeps pops up with the "USB Accessories Disabled" error after the above solutions, maybe the problem is deeper inside the device and needs to be handled by the professionals. Vah says:.

I have no idea what accessories it is referring to, all i have plugged in is keyboard and two ext hard drives which have been fine for the previous 2 years. Posted: January Nope - didnt work. No ports makes it useless to what i need this mac for. I only use it for business matters so nothing major and it still has stuff going wrong…so strange. My old mac lasted me for like 8 years. Replaced it and this is my second in 4 years so not happy to see them breaking down so easily.

Hope they can fig out why this is happening. Will check back in hopes of another solution other other than a board replacement. Help Translate iFixit. Back Answers Index. Ben Santos Rep: 4 3 1.

macos - Mac USB disabled due to too much power but nothing plugged in - Super User

David vidnelson Rep: 13 1. Hey everyone, I tried resetting SMC as well both ways and still nothing. Anybody else have this similar problem?? As flawless as a Mac can be, it is not completely immune to issues and sometimes the USB ports on the Mac can stop working inexplicably. You know you didn't do anything to cause the problem, but all of a sudden all your USB ports not working on Mac.

This issue can be frustrating. But before you think that the problem is the Mac, consider that sometimes USB devices can fail. Like we mentioned above, it is likely that the Mac is not the problem at all but the USB itself is failing to connect to the Mac. To check if this is a connection issue and that the USB you are using is damaged or not, try connecting a different USB device to the Mac to see if it's recognized.

This problem can also be caused by a software issue. In this case, you may want to restart the Mac to eliminate any software issues that could be causing problems.
