Apple has released Safari 7.0.6 for users of OS X 10.9 Mavericks and Safari 6.1.6 for users of 10.8 Mountain Lion and 10.7 Lion. Both updates improve memory handling to fix multiple WebKit memory corruption issues that could lead to unexpected application termination or arbitrary code execution if visiting a maliciously crafted Web site. (Seven Common Vulnerabilities and Exposures IDs, or CVE-IDs, are listed in the security note.) The two releases are available only through Software Update. (Free, 10.9+/10.7–10.8)
Open a Finder Window with the App Switcher
If you don't have any Finder windows open and want to switch to the Finder and open a window in one fell swoop, bring up the app switcher with Command-Tab and tab over to the Finder icon. While still holding down Command, press the Option key, and then release the Command key. You're switched to the Finder, with a new default window open for you.
