Get all kinds of information about your Mac machine using the Terminal
# generate a System Report.. system_profiler
This command is the command line equivalent of going to About This Mac > System Report..
You might need this if you write Bash scripts for example where you want to know if a program is installed on the system or not.
If you just run the command in the Terminal, it will start outputting all kinds of information, LOADS of it, including stuff like your machine’s UUID, available Wi-Fi networks, system diagnostic tests, details about what Applications are installed on the system and their versions, the fonts installed, hardware overview and so on..
So much information that you’ll not be able to scroll up and see everything in Terminal. A better approach is to redirect the output to a file, which we can easily view and search. I ended up with a file with more than 65000 lines
# save the profile to a text document called system_profile.txt on the Desktop system_profiler > /Users/$(whoami)/Desktop/system_profile.txt
Alternatively, you can also create a file that can be opened by the System Profiler.app
system_profiler -xml > /Users/$(whoami)/Desktop/system_profile.spx
You can open this file in the same view as System Report. The only difference is that now you have the report saved as a file (and can send the file to other people if need be, say you want tech support or something of the sort)
