Seems to be a damaged system. Try to fix it with Disk Utility.


If it doesn't help, start das Macbook und push key d immediately. Wait for the diagnose menu, and start it. Push the trackpad down, you hear a klick. At this point Multitouch Gestures are deactivated. If there is a failure, you should see a message.


Otherwise, install the Mac completely new.

I have quite the same problem with the only exception that both USB ports do not work as usual plus the SD card reader. Tried both the USB ports and the SD card reader. An SD card formatted MacOS extended works, the same card formatted exFAT and FAT32 doesn't. Interestingly, exFAT and FAT32 volumes show up in Disk Utility, but not in Finder or anywhere else.

Seems to be a problem related to the file systems supported.

Hi JackGB,

How have you solved the USB ports problem? Repair at Apple shop?


What I have noticed: some usb-sticks formatted FAT32 can be read other usb-sticks cannot be recognized by the system.


With the defective port I have used and external HDD (with own power supply) and it worked fine for more than a year ,..suddenly it stopped ?!


Best regards
