Instead of asking me if I want to save or run files, they just go into some sort of.ho;ding pen' at the bottom of the screen and I lose them when I close the computer down. Even those that the computer tells me it has downloaded it will not open, saying that I need to download the programme software - but it won't let me - very frustrating! Hi I was wondering if anyone can help me with an issue I currently have with my mac book air?

WordPress does not allow you to backup or download the plugins before you jettison them from your site. If you also manage your server and are fairly comfortable doing so, you may find a more contrived way to download installed plugins via directory manager app or FTP.

The plugins and extensions can help to reduce the size of an application and easily add new features. However, if you get the useless plugins and extensions, or the ones you never installed, they would slow down your Mac.

Before we start to introduce the way how to remove Plugins and extensions on Mac, let’s firstly figure outwhat exactly Add-on, Plug-in or Extension is.

Add-onXpadder macro guide. is a piece of software that enhances and customizes some kinds of applications. For instance, you can get add-ons to compare prices, check the weather or location, listen to music, or even change the look of your browser.

Plug-in, which cannot be run independently, is a piece of software which can only change something in the web pages. The most common usage of the plug-in can be adding some new features such as virus scanners, search-engines and so on.

Extensionis usually used in modifying the interface and/or behavior and extending the functionality of a web browser. Similar to add-ons, extension can add stuff into the browser for better performance.

Now, I would introduce two methods to delete the unwanted plugins and extensions on your Mac. Please check them out below.

Method 1: Remove Plugins & Extensions on Mac Manually

Safari, Chrome and Firefox may be the three most common browsers that Mac users would choose. In this way, here I want to introduce the way to remove those add-ons on Safari, Chrome and Firefox.

How to remove extensions on Safari manually?

1. Open Safari on your Mac and then choose “Safari > Preferences” in the top menu.

2. Open Extensions tab and go to the plugins or extensions you want to remove.

3. Click the Uninstall button.

How to manually remove extensions on Chrome?

If an extension has an icon in your Chrome toolbar, you can right-click the icon and then choose “Remove from Chrome”. If the extension doesn’t show in your toolbar, you need to:

1. Open Chrome and click on the menu button on the top right corner.

2. Go to “More tools > Extensions”.

I am trying to download 'Microsoft One Note' onto my MacBook Air but it won't seem to let me. It keeps coming up with an error message;

'We could not complete your purchase. (null) can’t be installed on “Macintosh HD” because OS X version 10.10 or later is required.'


I have however downloaded and installed the 'macOS High Sierra' recently.

This problem occurs to other apps as well when i try to download them off the App Store onto the MacBook Air.


Any help/advice on what to do?
