As if you were not already expecting it, after May 31, 2019, access to Intuit add-on services will be discontinued for all QuickBooks 2016 Desktop products. This year's sunset policy includes all versions of QuickBooks 2016 (Pro, Premier, Enterprise, Accountant, and Mac) and other products and maybe noted in the graphic illustration below. QuickBooks Desktop for Mac 2016 will officially be the last version of the product available, according to Intuit. QuickBooks Desktop Pro and Premier will continue to be available, but Mac for QuickBooks will be discontinued. Mac users, please keep in mind: 2016 will be supported until May 31, 2019. Statics meaning. As of May 31, 2007, QuickBooks 6.0 for Mac will be retired, and live technical support and add-on business services will be discontinued. Older versions of QuickBooks for Windows have already been retired, as have QuickBooks Pro 5.0 and prior versions for Mac. In 2016, Intuit discontinued QuickBooks for Mac, and users were forced to wait out their last three years of support or switch over to QuickBooks Online. QuickBooks then released a brand new 2019 version and has continued support with QuickBooks for Mac 2021. QuickBooks Desktop for Mac is a locally-installed program designed specifically for Macs. QuickBooks has determined that the 2015 and 2016 discontinued versions of QuickBooks Desktop for Mac are not compatible with Apple’s new MacOS, Catalina – which was released by Apple on October 7, 2019. Use of these discontinued versions of QuickBooks Mac with Catalina may cause data loss or crashes.
