Apple posted an update to Safari late yesterday that patches several vulnerabilities on both the Windows and Mac versions of the browser.
Apple also issued a Macbook Pro EFI Firmware Update that will apparently fix several issue to improve stability of the machine.
As always Apple is kind of light on the details here, but if you haven’t seen them yet, and want them now, just pop-up to the top left hand side of your screen and click Appe>Software Update to download.
