BSD Subsystem

The BSD Subsystem allows applications to interact with the system through the command lines and is required by such applications in order for them to operate correctly. The BSD Subsystem is installed by the Mac OS X Installer, but you can choose to not install it.

To custom install the BSD subsystem after Mac OS X 10.2 has already been installed:

• Insert the Mac OS X 10.2 Install Disc 1
• Double-click the Optional Installs folder
• Double-click the BSD Subsystem.pkg icon

If you do not see this package, choose File > Find and search the CD for BSD.pkg.

• Enter your account password when prompted
• Select the destination volume that contains Mac OS X 10.2
• Click Continue
• Once installation is complete, reinstall the Mac OS X 10.2.8 Combo Update

If you are running Mac OS X 10.3 and did not install this software, you need to reinstall Mac OS X and make sure that you select BSD Subsystem when you perform the installation.
