Apple released macOS Catalina 10.15 last night bringing a slew of new features, including Sidecar, Apple Arcade, Mac Catalyst, and a new Photos experience among other new features and improvements. The company is also incorporating the same Allow/Cancel app access prompts that look exactly what Apple used to diss Microsoft for.

But, new features aside, macOS 10.15 also fixes several security flaws, including some kernel issues and what appears to be a critical vulnerability where visiting a maliciously crafted website can reveal a victim’s browsing history.
