Before I start I would like to point out I use a MacBook I seen post here before with same problem but on a windows machine.
I am trying to install RetroPie on my Raspberry pi 3b. I downloaded RetroPie’s .img file.
So this is what I have done:
I have opened Etcher selected the img file, selected my flash pen which has my SD card inside (Sandisk 16GB) and I clicked on Flash.
It took about 30minutes to flash it, then another 10minutes to validate it. It then says Flash complete but below it a red marker saying 1 Failed Device.
The message underpinning the 1 Failed Device is as follows: "/dev/disk2: Source and Destination checksum do not match: 8d29 blah blah (more of the same) See Below for image.
I am new to Raspberry pi and Etcher so not the most advanced. I was just wondering if a kind soul can help me through this or if anyone incurred the same problem and what you did to find a solution. I would be very grateful if you can help me fix this.
Thanks in advance.
This is the error message I am getting.
