I need a MAC expert to edit and fix a dmg file -- 3

Hi there,
I need a MAC IOS expert who will debug a dmg file, which is basically scraping a website, reading 2 excel files, and generating an output. More details will be shared with short listed candidates. The scraper should be working fine; but gives error, you will need to debug and fix it.

Please only bid if you are MAC expert, using MAC computer, and start your bid with : I am MAC expert.

Thank you.
