Currently running QWIN Version R24.11 on CrossOver 19.0.1
I just started using CrossOver again when the Mac version of Quicken fell short of expectations...AGAIN. The saving grace is with the subscription model, I can download either Win or Mac version. So, I'm using Quicken for Windows (QWIN) on Crossover 19.0.1 and haven't run into any major issues. Everything syncs (OneStep, Quicken Cloud)and the Quicken Update feature does work inside the application as well. Because it syncs well, I've had no issues with with Quicken iOS app sending or receiving file updates so everything shows current.
I use OneDrive for my Quicken file storage and backup location so I can access it on my Mac as well as a Windows PC...no issues there. Just remember if you do this, close the Quicken app on the computer you're using once you're done with your session because it will corrupt the file if two concurrent computers are trying to access the same file. This comes directly from Quicken's support page.
If I come across any hiccups, etc I'll post them here as well as notify the Support Team.
