Prior to 2013, QuickBooks for Mac made ‘backup files’ the old fashioned way (kind of like the way QB-Windows does).
Still the same you know that backups of critical data are encouraged by all hardware and software vendors, so you have undoubtedly configured QB-Mac preferences to back-up regularly, perhaps at the end of every use. If you are like most Apple product users, you expect the stability of the Mac operating platform to be a perfect measure by which your QB-Mac should normally run, so you don’t anticipate needing to ever restore your QuickBooks Company file from a backup.
