My Quicken Deluxe for Mac is running slow. How do I speed it up?

In most cases, the cause for slow operation of Quicken Mac is that there is an open report window hidden beneath the main window. You're not aware of it because it's out of sight, but every time you enter or edit a transaction, Quicken is rebuilding the report.

Pull down your Window menu and see if anything is shown beneath the grayed-out "Sync Errors". This screenshot shows there are two open reports:

When you close the open windows, you'll find Quicken Mac returns to its normal, snappy self.

Please post back if this solves your problem or not. If not, please provide more details about the size of your data file and where exactly you have it saved on your Mac's hard drive.

@BillBill Your profile on this forum says you are using Quicken Windows; have you switched to Quicken Mac. (If so, you should update your profile by clicking you user icon at the far top right of the screen.)

If you are using Quicken Mac, and you have verified you have no open windows other than the main window, there next question is about the location of your Quicken data file. Is it stored on Dropbox? Is it stored on iCloud? (Your Mac may be set to store the contents of the Desktop and Documents folders on iCloud if iCloud Drive is set to On in System Settings > your account > iCloud.) Because the Quicken data file is a database which is frequently updated, it is important that it is stored on your local hard drive and not on any cloud storage service.
