Part 1: Installing Software Using Mac App Store

Many Mac users are actually used on using the Mac App Store for them to get software that they need on their Mac. All you have to do to install a certain software is very easy. The only things that you need to do are to launch the Mac App Store and then look for the App that you are looking for. Once that you already have looked for the software that you would want to install, just go ahead and click on the “Get” button and then click on the “Download” button. After that, the software that you have downloaded will be installed and will be located in the “Applications” folder. All updates of the application will also be available on the Mac App Store. Though using the Mac App Store is one of the most convenient ways for you to get some software that you need, it still does not have those other applications that you want. This is because of the following reasons.

• All the apps that you get from the Mac App Store are known to be sandboxed and come with a great security. But keep in mind that you have to limit what your application can access.

• Another thing is that Apple actually gets a cut for every time you purchase something on the Mac App Store. That is why some applications do not want it such as Adobe and Microsoft. That is why you cannot have these two be purchased in your Mac App Store.

Part 2: How to Download Software – DMG’s and Other Archives

That software that you have downloaded from outside Mac Store actually comes inside of a DMG file. All you have to do is to double-click on the DMG and then you will be able to see a Finder window on your screen.From there, all you have to do is to drag the software and then drop it on your Application folder. Then that is it, the software was successfully installed on your Mac. This is actually a very simple way on how to install certain software on your Mac. The DMG files that you have are actually mounted by your Mac system. Once that you are done installing the application, it is better if you try to unmount your DMG file in Finder. All you have to do here is to click on the “Eject” arrow.

Part 3: Installing Software From Archive Files and Loose Application Icons

There are instances wherein some software that you need actually comes on a ZIP, RAR, or 7ZIP archive rather than coming from a DMG file. The ZIP files can actually be opened fine out of the box. But for RAR and 7ZIP archives that you have on your Mac, you will be needing to have the Unarchiver. Once that you were able to open the archive, then you will be able to see the software icon that will appear on the same folder. From there, go ahead and simply drag the software icon and move it to your Applications folder.

Part 4: Install Software on PKG Installers

There will also be instances that you may encounter some files that are in PKG format. Also, there are times that you may see this inside of a DMG file. And other times you will download it directly. In this case, all you have to do is to double-click on the PKG file for you to run it. You will then be able to see the interface that has no difference with a Windows installation wizard. This method of installation actually has some functions that the regular drag and drop does not have. This includes installing system services and having to put the files elsewhere on your Mac. And once that you are done installing the software on your Mac, you can go ahead and have the PKG file and some DMG files that are associated with it be deleted.

Part 5: How to Install Software Using Steam and Some Other Third Party Applications

Of course, aside from the Mac App Store, there is also some other store wherein you can get a certain application from. An example of this is the Stream wherein people who are very fund with online and offline games get their software. And it is also because Steam actually offers software that is capable with Mac. Installing this software is actually a bit the same with Windows PC.Aside from that, there is also the Setup wherein it offers an unlimited access to several popular Mac applications and you would only have to pay for only $10 per month.
