It's $669USD compared to $79USD for that app only and converting is easier than trying to learn Biab.
PG should have a crossplatform format so it will install and work on both platforms.
As I said the only difference in the directory structure is Library > LibraryM
For $79 only it's worth trying first, it all worked for me I'm sure it will work for you.
If you are using AUD it's ridiculous the exchange rate at the moment to USD that's why I did an app only upgrade this year as the Audiophile was too much.
