Staying up-to-date with Twitter App for Mac

Today, I decided to try out the  Twitter app for Mac.  I installed the app from the Mac App Store.

It constantly updates to latest tweets I am following.  I also opted to keep in my dock.  The app also installs a tweet icon in the top menu bar for easy access.

Can I delete apps from my iTunes app to free up space on my laptop?

Periodically the space on my laptop gets lower than I like.  So, yesterday I decided to get rid of the numerous apps that I have stored in my iTunes app.  I was able to recover over 10 GB of much needed space. 

Did  you know that you do not need to keep copies of your iphone/ipad apps in iTunes, as you can re-download purchased content from the iTunes or App stores anyway. 

However, there may be a reason to keep some in your iTunes library.  If the developer pulls a particular version of an app and replaces it with another version, the only version available for re-download will be the current one, regardless of which version you originally purchased or want on your device.

So for any older devices you still have, i.e. an iPad 1, this may be the case for keeping an old app.  An iPad 1 cannot be updated beyond iOS 5.1.1 and many apps in the stores have been updated and now require iOS 5, 6 or 7.  In that situation, an iPad 1's owner may have only their own saved copies of compatible apps for re-installation if necessary.

So there are a few circumstances where you may want to keep some app's installers saved locally for yourself.
