What bookkeeping software is compatible with a 2015 Mac running macOS Monterey 12.7.4?

what bookeeping software will work for a 2015 desktop that runs monterey 12.7.4? My support for Quicken is ending, and this is a pretty old computer - I do not think it can update systems again.

Your 2015 iMac is indeed limited to Monterey, so I’d be careful about choosing another Mac app that may also drop Monterey soon.


One option worth looking at is GnuCash. Its current Mac version still supports Intel Macs running macOS 10.13 or later, so Monterey 12.7.4 is supported. It’s free and handles checking accounts, expenses, reports, and double-entry bookkeeping.


Quicken has also said that Quicken Classic Mac 8.5 is the final version supporting macOS 12 Monterey, which explains the notice you’re seeing.


Before switching, I’d check whether the replacement can import the Quicken data you actually need, especially if you rely on downloaded bank transactions or years of historical records.
