My Macbook Pro has been running with really high memory recently, I think it might be what's caused the whole system to freeze 2 or 3 times over the last couple of weeks. I'll have a bunch of apps open then, maybe it's just that? But I don't think my usage habits have changed in the last 6 months (in fact previously I've done a lot of heavy RAM things, like working with large data sets / ML), and I wasn't experiencing any kind of freezing.
By "freezing" I mean that the whole system locks up, can't move mouse etc., display is still on, and it takes ~10secs to come back. Once it didn't come back and I had to do a hard restart.
Looking at the Activity Monitor, the programs there definitely aren't using the 14GB of Memory Used, but from other articles here I see that this is normal. Maybe the high memory pressure isn't normal though. I'm really not using big RAM-heavy programs, and as i said, it's no heavier than what has been absolutely fine for the last months.
Anyone else experienced this? Would high memory pressure cause the kinds of freezing that i've experienced? Any fixes?
