Hi there,

Please assist I am using:

Mac Pro tower (2012) OS: Sierra 10.12.5
6 Core 2 x 2.4 ghz
64gb memory
4 hard drives totaling 6.5TB, Mac HD is SSD

I am running:

Pro Tools 12 HD with 2 x HDX cards
Logic 10

I am having a issue where when I work in ProTools or Logic the mac beachball appears every few minutes, even on a small session, which does not make sense as I have upgraded my Mac Pro to have so much power, also if i play music in iTunes or on Youtube I get this loud buzzing sound as If the HDX card has crashed and is struggling to keep up with the playback? I am thinking my Mac may be too old now to run Sierra and the latest updated softwares or maybe my processor is struggling to keep up? I am really lost and frustrated, maybe someone can offer some advise on a step forward.

Regards,
Victor
