I’ve been running it as a daily driver since the first day of the developer betas and have found it to be vastly more stable than the previous version, with basically no issues before this.

I don’t know what to tell you, beyond the fact that all use cases are not the same, apparently.

Unstable in what way?

Having to restart every day. CPU was also pretty much pegged nonstop when in clamshell and connected to two monitors. Catalina doesn't do that.

Thats strange, I run 2 34" displays from mine and haven't seen that. Did you upgrade or clean install?

Must be an absolute nightmare trying to handle every possible configuration someones Mac could be in. I dont envy the devs.
