How to find Storage Capacity on a Mac that is ready to sell and has no user account
I'm selling an old MacBook Air and have wiped it but forgot to get system profile information before I did so.
Most information I can get by booting in Single User mode and using terminal - e.g system_profiler SPHardwareDataType.
However, I cannot get the Hard Drive size. I have tried system_profiler SPStorageDataType but nothing comes up. Any ideas?
