I am having a similar issue. Attempting to flash HiveOS img to a 240gb Kingston SSD on a MacBook Pro using macOS Big Sur Version 11.6. I receive “error: EIO i/o error, write” about 10 seconds after starting the flash each time. I have tried all 4 usb-c slots on the computer and know the SSD is not faulty. Any tips/recommendations would be appreciated!

Hey @dmsynergy, I tried to reproduce the issue with the latest Etcher release (viz. v1.7.1) but could not reproduce it. I attempted flashing a 3 gig Ubuntu ISO to a SD card and Etcher flashed it in a single attempt without any warning/error. Would it be possible for you try v1.7.1? If the issue recurs with this version, then we could dig deeper. My machine config is: ```auto $ neofetch --stdout | egrep 'OS|Host|Kernel' OS: macOS 11.6 20G165 x86_64 Host: MacBookPro16,1 Kernel: 20.6.0 ``` Thanks and regards, Pranav ---

Also @dmsynergy, it would be good to try flashing to a different disk/card (just to rule out any media related idiosyncrasies).
