RAM usage is full on a Mac Pro (early 2009) - suggestions?
I have a Mac Pro (early 2009) with 2.66 Ghz Quad-Core Intel Xeon. I have 8 GB of Memory (1066 Mhz DDR3 ECC - 2 GB in all 4 slots).
Right now, I'm running Photos, iTunes, Safari and my Memory only shows 30 MB available. when I quit, iTunes and Photos - it only shows 1.42 GB available.
Question is - do I need to max out to 16 GB of RAM? Or is there some other method to stop the usage of RAM?
Mac Pro, OS X Yosemite (10.10.5), 8 GB RAM
