mac experiencing temporary USB loss of power li...

I have a MacBook Pro (Retina, 15-inch, Late 2013) 2.6 GHz Intel Core i7 with16 GB 1600 MHz DDR3 running 10.12.4 and as of recently I've been experiencing temporary glitches where the whole computer freezes for one second... it's very short but it happens every 5-10 minutes so it's majorly annoying... the mouse freezes, everything stops... I can tell it's a USB problem because when I have my iPhone plugged in I can see the battery charging icon come on after the freeze... this happens all the time, regardless of what software I am using or what I am doing... it's driving me nuts, what can I do?

Try resetting the SMC. If that does not help, take it in for testing/diagnosis.

Possible Fixes for El Capitan and Later Installations

 

You should try each, one at a time, then test to see if the problem is fixed before going on to the next.

 

    Be sure to backup your files before proceeding if possible.

 

  1. Resetting your Mac’s PRAM and NVRAM
  2. Reset the System Management Controller (SMC)
  3. Start the computer in Safe Mode, then restart normally. This is slower than a standard startup.
  4. Repair the disk by booting the from the Recovery HD. Immediately after the chime hold down the Command and R keys until the Utility Menu appears. Choose Disk Utility and click on the Continue button. Select the indented (usually, Macintosh HD) volume entry from the side list.  Click on the First Aid button in the toolbar. Wait for the Done button to appear. Quit Disk Utility and return to the Utility Menu. Restart the computer from the Apple Menu.
  5. Create a New User Account Open Users & Groups preferences. Click on the lock icon and enter your Admin password when prompted. On the left under Current User click on the Add [+] button below Login Options. Setup a new Admin user account. Upon completion log out of your current account then log into the new account. If your problems cease, then consider switching to the new account and transferring your files to it - Transferring files from one User Account to another.
  6. Install Combo Updater Download macOS Sierra 10.12.4 Combo Update and install.
  7. Reinstall OS X by booting from the Recovery HD using the Command and R keys. When the Utility Menu appears select Reinstall OS X then click on the Continue button.
  8. Erase and Install OS X Restart the computer. Immediately after the chime hold down the Command and R keys until the Apple logo appears. When the Utility Menu appears:
  1. Select Disk Utility from the Utility Menu and click on Continue button.
  2. When Disk Utility loads select the drive (out-dented entry) from the Device list.
  3. Click on the Erase icon in Disk Utility's toolbar. A panel will drop down.
  4. Set the Format type to Mac OS Extended (Journaled.)
  5. Click on the Apply button, then wait for the Done button to activate and click on it.
  6. Quit Disk Utility and return to the Utility Menu.
  7. Select Reinstall OS X and click on the Continue button.


Same here. Retina 15", Late 2013. Happens in both Sierra and High Sierra.

Did you solve the problem?
