One of the features that makes macOS so user friendly is the ease of installing and removing apps.
There are two ways to remove any pre-installed app.
Of course, you won't feel such a burden if your Mac comes with 1TB or more of storage, but add in iMovie and Photos to the pot and you'll find yourself freeing up to 5GB of space just by removing the pre-installed software. Now, just imagine how many Photoshop files you could store in that free disk space! There is a good reason for not keeping these apps, too, because if you have limited storage – let's say a 128GB flash drive – then uninstalling GarageBand will save you quite a lot of space, up to 1GB.
