On the MacOS X system, it all revolves around the App Store, which you can either get to by using Spotlight or you can get to App Store from the Apple menu on the top left of your computer. Now you can go to a central spot on your computer and not only search through thousands of programs, apps and games, but if there’s an update released to any program you’ve downloaded, that’ll be applied automatically too. Apple introduced the App Store for the Mac system and Microsoft the Microsoft Store – and Google has Google Play for Android apps! – and it’s all changed for the better. Then we got to digital downloads which made that a lot easier but still left you hunting around online trying to find vendors with good solutions.
Used to be that if you wanted to get games, utilities or other programs, you’d buy a box or CDROM at the store and install it.
