Everyone has heard of the computer program that allows the user to be able to run all applications through a USB drive. It is called Mac OS X Download Manager. It is part of the OS X operating system and is extremely powerful. The process of copying files is made very easy, you just need to make sure you have the correct application installed on your computer before you can begin. One of the most popular choices of software that you can use is the Adobe Creative Suite. They include PhotoShop, Illustrator, InDesign, Premiere Pro, etc.
You can also download the Steam application for Mac. This application is similar to the Steam application used in your computer. It allows you to run all your applications, games, pictures, video, etc. as well as playing audio, downloading and burning DVDs. There are other applications like Garage Band, IZotope RX, etc. that you can use. It is up to you to decide which application will best suit your needs.
It is better to have two applications. If you will be downloading a large file then it is better to use the application that offers the best performance. You can try to download any application you like and see how it works out for you. You may find that you really do not need to purchase the software you are currently using and might just like to upgrade to a new application instead. Since you already have the application installed on your computer, you will not have to worry about updating it and downloading the new version.
