Get System Profiler Information without a macOS Installation I have a bunch of factory reset MacBooks. I want to know the CPU, memory and storage configuration for each of these machines. What is the fastest way to get this information without to go through the initial setup and resetting the machines again?

I have a USB installer of macOS 10.13 and a macOS installation on an external hard drive, which needs unusually long to load on each machine.

What are my options?
Using bootable Ubuntu You can check the Computer Feature fastest.


Make USB drive bootable with Ubuntu
Connect that USB drive to Computer and Boot from it
then go to about computer in dropdown menu at top right corner.
here you will get all details of computer such as HardDisc Size, CPU, GPU, RAM,   etc


Using this method you don't have to go through time consuming installation processes.
