Moneywell.

MoneyWell - Personal Finance Software for Mac and iPhone

I've been using it for 2+ years since I switched over to Mac's. EXCELLENT customer support. Tried just about everything else to include YNAB. MW is an envelope based budgeting approach, a bit odd for some, but if you are looking into YNAB you are almost there. Direct connect for most banks, unlike YNAB. Version 2.0 is rolling out very very soon which is supposed to have many new features such as investment accounts, etc. etc.
