Another "Audio File is Loading Slowly" [Resolved]

This only happens when playing an album of Hi-Rez FLAC files. The message mostly comes up near the end of the track and then it skips to the next song. The next song skips forward sooner and another message is seen.
I’m running Roon on a MacBook Pro 5.1, Intel Core 2 Duo, 2.4 Ghz, 4 GB memory. 750 GB HD 1/2 full. 700 albums plus Tidal. Typically I use the MacBook on the coffee table and send music via RAAT to the Auralic Aries. There has never been a problem until lately so I’m suspecting the latest build because connecting the MacBook directly to the Auralic Vega DAC via USB does not solve the problem.
I do understand that new features can increase the load on the hardware. My question is, given the relatively light load, should I be having inadequate hardware issues? If so, will changing to an SSD likely solve my problem?
