The latest version of Mac OS X 10.9 Mavericks is on my iMac and running smoothly. The only real change I’ve noticed is a slight increase in speed of Google Chrome, which is my primary browser, along with the Finder. Other applications seem snappier as well. My long time gripe (unspoken till now) about Macs was that shy of being fresh out of the box, they seem to lack a certain snappiness when switching between applications. Perhaps it’s just using the same machine too long between clean installations of the system software. Perhaps I’ll use the savvy instructions from Ars Technica entitled “How to make your own bootable OS X 10.9 Mavericks USB install drive”.
