For Quicken on Mac implement the cash management that exists in Windows

R1456

Quicken for Windows has an option …"to specify how Quicken handles Money Market Funds (MMF) in brokerage accounts.You can override the default behavior and specify whether to treat the MMF as Cash or a Position, and also adjust how the associated Cash Balance is calculated.'

This same option should exist in Quicken Classic for Mac.

The issue is mentioned in other threads, in the context of Schwab's SWVXX money management fund.
