I have a MacBook and have recently upgraded the operating system.  I have waited to do so because i was using quickbooks 2014 and didn't want to lose important information for the business.  I had no other choice but to update the OS so i can file taxes.  With that being said, I also purchased QB 2019 and have lost every document, invoice, customer, etc for the last 5 years.  This is information that we desperately need.  Is there any way to open this information or to convert it over to QB 2019?
