I purchased Liquid Ledger a few months ago and installed it on my MacBook Pro with OS 10.5. The software has been a constant source of frustration. Features described in the built in "help" feature (which is minimal and rudimentary) are not working. For example: entering transactions manually is not working and therefore it is impossible to fill in transactions missing in the datafiles downloaded from the banks. The import function is inconsistent and often fails without diagnostic that may help correct the problem. The manufacture is unresponsive to queries regarding these problems. I feel like I threw my money away with this purchase.
