Hi, today I've tried to make a clone of my raspberry pi image from a 32 GB SD card to a 64 GB sandisk USB. As the program is writing partitions, the second stage, the loading bar stops moving. When I click on the application bar, the whole system locks up. Only the mouse cursor can be moved. CTRL ALT DEL does not work. Neither does the GUI interface. How do I copy the SD card to the USB drive?
FYI, I only have raspberry pi 3 as Linux. Over locked at 1.36 ghz. 120mb Gpu split. I also have a Mac.
