After updating to OS X 10.8.3 version of OS X 10.8.4 does not work after a reboot USB-ports on Computers Mac mini (MC816). Povtoranaya to reinstall your operating system (from App Store) does not eliminate the problem.
Mac mini, OS X Mountain Lion (10.8), OS X 10.8.4
Configuration Mac mini (2011 later) MC816:
- Memory: 8GB (DDR-3)
- Processor: Intel Core i5 (2.5 GHz)
- Video: AMD Radeon HD6630 (256 Mb)
- SSD (2,5" Kingstone) 120 Gb
PS: utility MacKeeper is NOT INSTALLED! New installation of the OS X 10.8.4 (App Store) does not help solving the problem with non-working USB-ports. (((((
Try a PRAM reset. This sometimes resolves similar issues.
Thanks for the advice keg55. I tried to reset NVRAM & SMC - nothing has changed. 😢
Have you tried a Verify Disk from Disk Utility? If there are any errors, do the Repair Disk. Also, try a Repair Permissions.
It's odd that after an OS update, your USB ports suddenly don't work. All 4 ports are not able to see and use a USB device (e.g. USB thumb drive or USB external drive)?
Dear keg55 try to answer the points you (sorry for my bad English, I'm from Russia):
- +5V voltage is present on the USB-ports.
- After the operating system is not working only the mouse and keyboard, but after sending the computer into sleep mode (press on / off) ports are included. To enable the ports necessary every time you reboot go into sleep mode.
- To reinstall your operating system from the MAS result does not. After reinstalling the bug persists.
I'm not sure what else to suggest other than taking your Mac Mini into an Apple Store to have their techs look into the issue. Hopefully, you have AppleCare and your Mac is still covered.
It seems you've tried all of the following without success.
