yea, I assumed that. Heres what I did for any other recent switchers.
go to your pc right click your playlist and choose export song list
Choose .xml or .txt I dont think it matters, I used xml
copy it to a usb thumb drive, cd, ect.
Repeat for all of the playlists
go to your mac, open itunes
go to file> import
select the files you just saved and click choose
