QuickBooks update for macOS Sierra

With a time machine backup, you could revert. If you had a 'full

system clone' - you could just restart in the older full macOS X.

Helps before you consider an upgrade to a new mac OS that the

third-party software makers too may be slow on the uptake. And

drivers for third-party devices generally drive people a little nutty.

{My latest Mac OS is 10.9.5; with El Capitan holding in app folder.}

There may be more information or an older version available to

if online versions aren't suitable. - A QB16 is ready for Sierra.

As some users do not wish to subscribe to monthly fees, to be

able to keep the older software running a little while longer helps.

The retail QB desktop version had been reduced for a limited time;

($200?) I'd read about it a few days ago. Still not inexpensive though.

Sorry that you've found issue with Upgrade to an all new system.
