I downloaded the app after installing Mac OS High Sierra but formatted my drive. When I copied it to a USB drive, it didn’t open properly—it showed an error about possible damage. Now I’m unsure how to use it beyond reinstalling. It’s a 6GB drive.
Are you checking the security options? If not, the USB device may not be saved in exfat or hfs format.
You transferred it from USB to Mac before, but now it crashes on the Mac.
