Q: MacBook 12 fails to recognize some USB flash drives

This is the same problem I had before. I thought it had been corrected by I was wrong.

Since the latest update to OS X 10.11.4, my MacBook 12" fails to recognize some USB flash drives. I checked them on another computer and the format and partition guide is the same.

The flash drives it recognize are SanDisk and Lexar.

I have several Silicon Power J80 that are not mounted on the desktop of the MacBook, but they work perfectly well with my iMac27.

Something must have changed. Is anybody else having the same problem?
