Using Apple Server Diagnostics
If you suspect a hardware problem, use Apple Server Diagnostics to determine if there’s
a problem with one of the Mac mini components.
To use Apple Server Diagnostics:
1 Disconnect all external devices from your Mac mini, except the keyboard and mouse.
If you have an Ethernet cable connected, disconnect it.
2 Restart your Mac mini while holding down the D key.
3 When the Apple Server Diagnostics chooser screen appears, select the language you
want to use.
4 Press the Return key or click the right arrow button.
5 When the Apple Server Diagnostics main screen appears (after about 45 seconds),
follow the onscreen instructions.
6 If Apple Server Diagnostics detects a problem, it displays an error code. Make a note
of the error code before pursuing support options. If Apple Server Diagnostics doesn’t
detect a hardware failure, the problem may be software-related.
For more information, see the Apple Server Diagnostics documentation on the
Admin Tools disc.
Problems with Your Internet Connection
Your Mac mini has the Setup Assistant application to walk you through setting up an
Internet connection. Open System Preferences and click Network. Click the “Assist me”
button to open Network Setup Assistant.
