From my tests, and no scripting (I'm really new at that), but with post-Restore directory name changes, I was able to construct a reasonable copy of the PC library onto MC 18 Mac. I can go through the process again to take screen shots. The findings:
--The process involved a local hard drive location (attached to Mac).
--The data for the most part only needs the directory location to change except for a small problem with entries that begin with a certain characters such as a period (like .38 Special) (see below).
--MC 18 PC can translate iTunes XML playlists without any modifications. However, exporting playlists from MC 18 PC to MC 18 Mac does not work. Therefore, if you wish to use iTunes PC Playlists in MC 18 Mac, make sure they're imported into MC 18 PC before backing up the MC 18 PC library.
--The Restore appears to wipe out the previous data in the library.
--Except for the odd character issue, the directory change can be done using Rename, Move, and Copy Files from the Library Tools menu selection (right clicking on a song or batch of songs).
--The path must match the source of the file on the drive connected to the Mac.
The character issue I encountered was during my initial testing that included a couple songs by .38 Special. For some reason, the conversion rule of [Album]\[Artist] caused the underscore character ( _ ) to change to a period. I had to apply an extra Find and Replace to maintain the integrity of the path. Curiously enough, the problem did not happen on the Album or Song part of these files, nor on the other test songs, and several had underscores that stood for various characters such as ( " ) and ( ! ).
Therefore, apart from that one issue, I was able to change the PC file address to the one on the Mac drive, updated the Tag (from file) info, and was done.
Example: D:\Music to /Users/name/Music/ . An external drive may need additional info to target the correct drive (Ex: /Volumes/Media Library/...).
I haven't tested any Concert music pieces with extended filenames and special characters as of yet.
A thought: I wondered if MC 18 Mac might incorporate Applescript into the system besides the JRiver script language? Just wondering....not wanting to set up a separate thread for that right now, just something for the wish list.
I'm sprucing up my music files for the big move to come later this year (it's a large library). Keep up the good work!
