There’s something of a misconception when it comes to the Mac. While powerful tools like Photoshop or Final Cut Pro certainly have price tags commensurate with their robust feature sets, many of the greatest Mac apps won’t cost you anything more than the time they take to download them. A quick note before we begin. Apple has changed its security settings in macOS, so you’ll need to allow your system to open a couple of these apps. A dialogue box may pop up telling you a certain app 'is an application downloaded from the Internet. Are you sure you want to open it?'
Click Open to proceed with the installation.
