how to block Flash in Safari

Safari Preferences Security

If you’re worried about news like yet another Flash vulnerability, the first thing to note is that Apple has moved to block all but the latest version.

However, given that exploits of Flash seem to occur sometimes within days of even new releases, it might be wise to think about blocking Flash altogether in your day-to-day browser.

Fortunately, that’s pretty easy to do in Safari. Just go to Safari’s Preferences > Security tab, and uncheck the ‘Allow Plug-ins’ box at the bottom. You can manage which websites are allowed access to Flash from the adjacent button, but an alternative strategy is to use a different browser (Firefox or Opera for example) for only viewing sites where you need Flash access.

Either way, its seems wise to make sure that Flash isn’t allowed unrestricted access on your main browser.

can’t preview movies in Finder?



One of the features I really love in OS X is the ability to preview anything by selecting the file in finder and pressing the spacebar – formally called ‘Quick Look’ – without actually having to open the full app. This is great for both music and movies.

However, if you uninstalled Perian or Flip4Mac or haven’t updated them recently, you will find that a lot of movie files – like .avi, for example – which are not fully supported in QuickTime won’t preview. The answer is to get the latest versions of these two plug-ins:

Perian 1.2.3
http://perian.org

Flip4Mac
http://flip4mac.en.softonic.com/mac

(hit the green download button (free), ignore the one trying to sell you a paid version).

You should then be able to see any movie using Quick Look.
