Hi - I've recently moved my large iTunes media folder (25,000+ songs) from my MacBook to a QNAP 251+ NAS, following Kirk's excellent 2015 article in MacWorld. I'm also a heavy iOS user with iTunes Match. The NAS setup works fantastic, except when it has hiccups, which happens weekly. The issues seem to occur when for unknown reasons, iTunes reverts the Media file location to that of the MacBook SSD, rather than the appropriate folder on the NAS, despite my care to ensure that NAS remains mounted on the MacBook. This would not be so bad, because it can easily changed back to the NAS in iTunes preferences. Except that when I do that, it takes an annoying 2 hours to reorganize my iTunes library, during which period iTunes is unusable. Is there any way to make iTunes more stable on the NAS, while preserving all the Match functionality? Thanks.
