You Need to Be Serious About It
Are you sure you're a developer? Did you free up disk space?
If you fire up a terminal on your Mac and run a command that shows you’re going to use the computer beyond the usual facebooks and pornhubs (try
git --version or some such), the OS will offer to install the Command Line Developer Tools. It doesn’t say which tools those are but
git is included, so it is worth at least something.
To install those Command Line Developer Tools you’ll need at least 2.86 GB of free disk space, otherwise the installer just gives up. Howerver, after the installation is done, the free disk space is only down by about 400 MB.
These Macs are so logical and easy to understand that I wanna cry sometimes.
