Permanently Turn off Mountain Lions “App updates available” without updating

You can’t turn it off completely. This is obnoxious at best. BUT…

Here is what you can do.

For the software update you would like to hide – make sure the full description of the update is shown – click “More…” if needed to show the full description Right click on the update window.  Select “Hide update”

This will hide the update and it will not show in the App Store Updates Window or counted on the dock icon.

To restore – select “Show all software updates..” which is now shown in the App store “Store” menu.  Then “Reload Page” from the Store menu.

Notification Center in iOS has changed the way we view, read, and reply to messages, calendar appointments, and push notifications from social networking services like Twitter and Facebook. In Mountain Lion, this feature does this and more, allowing you to tweet conveniently from your Mac. Continue reading as we take you on a walkthrough of all the features in Notification Center.

Notification Center Basics

To open the notification center on your Mac, click on the icon beside of Spotlight in the right-most corner of the menu bar (it looks like a bulleted item list). This action will cause the Mac desktop to move over, and a new sidebar will appear on your Mac. This is where all registered notifications will appear.

This is only one part of the notification center, however. Apps can send along important information in the form of popups that appear in the top right corner of your screen. Here, for instance, iCal has sent a notification about an upcoming event. You can choose to close or snooze the event reminder.

All of these notifications are great, but if you are in a meeting, or giving a presentation, it can be important to silence personal notifications from being visible by others. Fortunately, Apple has included an easy way to do this. Simply open Notification Center and scroll to the top of the sidebar. You will see a small switch to “Show Alerts and Banners.” By flipping this switch off, you will effectively silence all Notification Center alerts for the entire day (the alerts will resume the next day or whenever you flip the switch back on). Notification Center alerts will also be silenced whenever you plug in an external projector to your Mac.

Tweaking Notification Center

Notification Center has many preferences that can be tweaked on an app-by-app basis. To do this, open System Preferences > Notifications. Once here, you will notice all of the apps registered to send notifications to Notification Center will be listed on the left-hand side of the preference pane.

Clicking on one of these apps will give you preferences for the alert style, and what type of alerts are sent. For each app, you can choose to have no alert, a banner alert, or a regular alert. The difference between banners and alerts is that a banner is automatically dismissed, while an alert must be manually dismissed by clicking one of the available buttons in the alert.

Here, you can also select whether or not to show the app in the Notification Center, and how many notifications to show in the Notification Center sidebar at one time. You can also choose whether or not to badge the app icon in the Dock (essentially displaying how many notifications are currently waiting for you), or whether or not to play a sound when receiving notifications.


By default, in the Notification Center, notifications are listed on an app-by-app basis and are automatically sorted by time of notification arrival. To rearrange the app to your taste manually, select “Manually” from Sort Notification Center by drop-down menu at the bottom of the Notifications system preference pane. Next, drag and drop the apps names in the Notification system preference pane in the order that you would like them to appear in the Notification Center. As you receive notifications from these apps, they will stack up in this order in the Notification Center.

The Share Button

One of the most touted features of Notification Center is the ability to update your social networking status on Twitter right from the sidebar on your Mac. To enable this feature, select the “Share Button” feature in the Notification Center, and check the box labeled “Show share button in Notification Center.” You will also need to be signed into Twitter by visiting the “Mail, Contacts & Calendars” preference pane.

Next, open the Notification Center and click on the button labeled “Click to Tweet.” This button will open what is known as a “Tweet Sheet.” In this sheet, you can type your 140-character thought, and even add your location to the tweet before clicking “Send” to post the message to your Twitter account.

Apple notes in the Mountain Lion features that coming this fall, Facebook integration in a future update will allow users to post updates to their Facebook accounts as well.
