After updating my Mac to the latest system Ventura 13.1 - It did not appear that I could see my FromTo folder or DKV###### network for the Disklavier.
Here are the steps to access the To/From PC using a Mac with the new system:
1: Open a finder window
2: Click on Network, under locations on the lefthand sidebar.
3: Goto the menubar and select the “Go” Menu and the “Connect to Server” option in the pulldown menu
4: Type in smb://dkv###### that corresponds to your piano
Select Guest and hit return.
The FromTo PC option should also be selected. Once selected, you will see any files or folders that you have stored on your piano in the FromTo folder in the finder directory. You can drag midi files from your Mac directory to that area. Once they are transferred to the folder on your piano, use Refresh PC option in DKVBrowser to see the files on your piano's FromTo folder.
