I will upload the last version of this soft in MAC app format too, so you will be able to use this application also on MAC. You will find the link in "Other Software" area of this forum.
Be aware, I didn't made any tests on it, so make some tests before use it on your big playlist files. Make a test playlist file on your keyboard, or make a copy of your original file before use it on MAC version of my soft.
Edited:
I have made a simple test of appending a playlist and save the new playlist, and everything is safe.
I saw the "Open Folder" button on "Add Record" screen does not work under MAC. It will open an empty dialog box with no folder to choose. I will try to check this thing next week...
Best regards,
