Better Preset Sync. You don't even need to import your banks into the Mac version. It will happen automatically if you do this:

Open the standalone app on your iPad and turn on the Preset Sync button. Choose Enable Sync when prompted. Repeat these steps in the standalone app on your Mac.
Both devices must use the same iCloud account. Leave both apps open while your presets sync automatically.
To check sync status or manually refresh, tap the ⓘ beside the preset-sync control and choose Sync Now.
