Sorry, just read that and realised how ambiguous it comes across. I know how to write the .img to SD card, the problem is I don't seem to be able to extract the .img from the zip file. It goes through extraction and I end up with a .cpgz folder. It throws up this error in console :- mdworker[11172]: zip importer encountered an error (3) scanning "/Users/deanmichaelcummings/Downloads/wolfson_3.10_master 2.zip".
