QB Issue Resolution:
You should order Quickbooks Mac 2015 – that’s the latest version and is officially supported on Apple’s Yosemite OS. Intuit has a money-back return policy. I’m not sure all outlets have it though – check where you bought it. Note you can order it online from Amazon at a discount and just download it.
All newer versions should be able to import QB Mac 5 data. That’s a really old version and not many people are importing it any more though – who knows if your data has some issue after all those years of use. Before importing it (and while still on the PowerPC Mac) first make a backup of your company file and put it in a safe place (like a CD or a USB key). Then run File->Utilities->Verify. If any problems are reported run File->Utilities->Rebuild.
After that, get your file to the new machine (again a USB key will work, or use networking). Then launch QuickBooks Mac 2015 (or 2014, but I do strongly suggest getting 2015) and launch it. It may detect an update is available – go ahead and apply that. Finally choose File->Open and select your old company file. It should upgrade. Run File->Utilities->Verify after the upgrade and, if a problem is reported, File->Utilities->Rebuild (now on the new copy of QB).
