Welcome back, Rob.

Allow me to share some insights about the System Requirements for QuickBooks for Mac 2021.

As of the moment, we haven't received any updates yet that MacOS Ventura 13.0 will run seamlessly for QB for Mac 2021. That said, we can't guarantee it will run without any issues.

Listed below are the minimum system requirements for QuickBooks Desktop for Mac 2021:

• A minimum of Mac OS X v10.15 (Catalina) is needed to install.
• CD/DVD drive or internet connection to download the product.
• Product registration required.
• Intel processor, Core 2 Duo or higher.
• Multi-user Server: Intel Core 2 Duo or higher processor to run a server.

• 250 MB of available storage.
• Macintosh-compatible printer if you plan to print invoices, checks, deposit slips, lists, purchase orders, mailing labels, reports, or graphs.
