SH-01A Version 1.07.

I've recently just purchased the JP-08, SH-01A & TR-08 second hand. I am fairly new to synthesizers in general & am just learning them & I'm not the best with computers either. I was able to download the driver for the SH-01A & was hoping to update the system program version to 1.07 as it is currently at 1.03. When I try to open the download from my computer (MacOS 10.15) a message appears saying "Unable to expand 'BQ3_UPD.BIN' it is an unsupported format." I had no issues downloading anything with the JP-08.

If anyone has any advice it would be much appreciated.
