I'd like to reiterate this. I just updated to 10.15.5 on Friday and my 2017 MacBookPro 13' has been crashing every single day since. It's not as bad as the crashes I experienced in early April, two updates back. My Mac was basically bricked for a few days. But to have this happening now again is absolutely intolerable.
How can you guys release such unstable updates like this? I've been a an Apple user since 1986 and never had such bad instability issues. The quality control is terrible. I don't have another computer for my work. Please issue a fix to prevent theses crashes from continually taking place. Catalina is terrible.
