QB Desktop on Mac 2019 - Will it run on MacOS 10.11.6 (El Capitan)?

Pleased to have you here, @jd68.

I'd be glad to share additional information about QuickBooks for Mac 2019.

QuickBooks for Mac, also referred to as Quickbooks Pro for Mac, is the desktop version for Apple's Mac operating system. It is specially built as a Mac product from the ground up, so the interface will be familiar if you’ve used other Mac applications. 

Here 's the minimum requirements for this new QuickBooks version:

• At least macOS 10.12 (Sierra); supported by macOS 10.13 (High Sierra), macOS 10.14 (Mojave)
• Intel processor, Core 2 Duo or higher
• Multiuser Server: Intel Core 2 Duo or higher processor to run server
• 2 GB RAM (4 GB RAM recommended)
• 250 MB of available disk space
• CD/DVD drive or Internet connection for downloaded installation
• Printer: 100% Macintosh-compatible printer, if you plan to print invoices, checks, deposit slips, lists, purchase orders, mailing labels, reports, or graphs
• Checks: Use Intuit Checks if you plan to print checks. Canadian Image Ready Checks are not supported
• Product registration required

It came with these great enhancements in the new QuickBooks for Mac 2019:

• iCloud document sharing: A convenient method for sharing QuickBooks for Mac file using iCloud sync.  Change your books on your work Mac computer then continue where you left off on your home Mac computer.
• Reconciliation Discrepancy report: This identifies changes made to reconciled transactions created with this release or later.
• Email tracking for customers and vendors: Track dates emails sent with a tab in the Vendor and Customer centers.
• Past Due stamp on invoices: you can have PAST DUE appear on invoices.
• Square transactions import: You can import sales data from Square via use of .csv file type.
