The two relatively lower posts I've seen here are both higher RAM, 32GB and 64GB. I wonder there's anything to read into this.

Well... 8 Gb should be enough for everyone? :)

I seem to be using 12 Gb on this mbpro with just firefox, mail and a few chat apps open. But it has 16 G ram.

On my 32 Gb mac mini that has work stuff open i use 26 Gb atm.

Both are Intel, not brave enough to make the architecture jump yet.

If you use more than the physical ram the Mx machines may be more responsive than the intel ones, but they're still going to swap.

It should be a little over 4 years old now.

Thanks for sharing, is this a 1TB drive?

Going by the percentage used, looks like an expected lifespan of 1200TBW.

It's a 512 G drive.

Thanks.
