Unsafe Shutdowns: 13 That's a bit worrisome. Has your mac been freezing/crashing?

I hold the record for "unsafe shutdowns." One reason, is that I am constantly using Xcode, which is a bug farm, and SourceSafe used to crash like crazy. Also, some of the apps I'm developing don't start off, perfect. I spend a lot of time crashing. The advent of the M1 seems to have ushered in a new threading system. The threads act weird, now (look at how long it takes to resolve your stack, on a breakpoint). I'm pr…

> And I stopped playing Borderlands 3, because it liked to crash hard.

In all fairness, it also does this on underpowered Windows/Linux hardware. It really is just a poorly made game, not Wine/Apple's fault here.

I'm not sure but I wonder if it happens when you do the macos install / recovery mode where it does repeated reboots.

I only see that counter going up when a system hard freezes/crashes or the system loses power. I'm not sure macos recovery/install would cause that.

Yeah, that'd definitely do it. I'm really interested in knowing if people see that stat going up without crashing/power loss.

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.

Bought my M1 right after launch and that’s crazy to do in 3 months. I’ll post my numbers when I get back. Mine is personal use only, no work.
