You can get this information with the macOS command:

Code:

system_profiler

See summary man page here:

https://www.unix.com/man-page/mojave/8/system_profiler/

Code:

root#  system_profiler -usage
Usage: system_profiler [-listDataTypes]
       system_profiler [-xml] [-timeout n] [-detailLevel n]
       system_profiler [-xml] [-timeout n] [dataType1 ... dataTypeN]

  -detailLevel n    specifies the level of detail for the report
                      mini = short report (contains no identifying or personal information)
                      basic = basic hardware and network information
                      full = all available information

  -listDataTypes    lists all the available datatypes

  -xml              generates xml output instead of plain text
                    if redirected to a file with the extension ".spx"
                    the file can be opened in System Profiler.app

  -timeout          specifies the maximum time to spend gathering information
                    the default is 180 seconds, 0 means no timeout

  Redirect stderr to /dev/null to suppress progress and error messages.

Examples:

  system_profiler
     Generates a text report with the standard detail level.

  system_profiler -detailLevel mini
     Generates a short report without identifying/personal information.

  system_profiler -listDataTypes
     Shows a list of the available data types.

  system_profiler SPSoftwareDataType SPNetworkDataType
     Generates a text report containing only software and network data.

  system_profiler -xml >MySystem.spx
     Creates a XML file which can be opened by System Profiler.app

       -O, --original-string=value
	      XML is contained in the supplied string

   Operation:

	      # cibadmin --query > cib-old.xml

	      # cibadmin --query > cib-new.xml

       Calculate and save the difference between the two files:

	      # crm_diff --original cib-old.xml --new cib-new.xml > patch.xml

       Apply the patch to the original file:

	      # crm_diff --original cib-old.xml --patch patch.xml > updated.xml

       Apply the patch to the running cluster:

	      # cibadmin --patch patch.xml
