Such RAM usage isn't just "normal" - its excellent!
Mind if I use my old 3.5 in HDD?I stand corrected. Slap me with a SSD!
The combination of Free, Wired, Active, Inactive & Used memory statistics in previous versions of Activity Monitor have been replaced in Mavericks with an easy to read "Memory Pressure" graph.
Memory pressure is indicated by color:
- Green RAM memory resources are available.
- Amber RAM memory resources are being tasked.
- Red RAM memory resources are depleted and OS X is using the drive for memory.
