iTUNES LIBRARY NOT UPDATING IN REKORDBOX

Hello,

I've recently migrated by Rekordbox to a new laptop. When I initially transferred them across, I had no issues with the iTunes sync. But since then, my iTunes tree in Rekordbox will not update, and I can't update my USB's.

I've refreshed a million times and I believe i've read and tried almost every thread and suggestion on the issue but nothing seems to work.

When I look at my masterPlaylists2.xml and datafile.edb, they're from last month and don't seem to be updating either - perhaps that could be the issue?

My iTunes has selected "Share itunes Library XML with other applications".

I also tried re-installing Rekordbox (deleting the app and re-installing) but no dice. I was also weary of losing all my cuepoints so not sure whether to try again (I've backed up my library incase).

I'm running the latest Rekordbox (4.2.5) and am on Mac 10.12.3

Any help would be much appreciated!!
