Service Considerations:

Software:

This computer ships with a CPU-specific version of the operating system. Check article HT204319: Mac OS X versions (builds) for computers to make sure system build is correct for this computer model. Using Software Update, check for and apply the latest software and firmware updates.

Serial Number Location:

The serial number is located on the inlet on the bottom of the computer.

• Mac Pro (Late 2013) is organized into four main assemblies of parts, which appear as headings in the Take Apart section of the Service Guide table of contents:
• Housing / Memory / Storage / Logic Board
• Exhaust Assembly
• I/O Wall and Power Supply Assembly
• Core Assembly
• The computer enclosure is polished aluminum that must be handled with care to avoid scratching.
• When replacing a part, you must use the screws shipped with the replacement part, both for the new part installation and for reinstalling parts included in the procedure's 'First Steps' (see 'Screws' in General Take Apart Information).
• When replacing a part that requires removing the roof, a new roof must be installed. The replacement roof comes with the service part.
• The power button is not a service part. To replace the power button, you must replace the I/O wall.
• Screws for logic board and bus bars must be tightened to specified torque values. A torque driver with required bits is available through Apple (see 'Tools' in General Take Apart Information). Torque values for all screws are listed in the Mac Pro (Late 2013) Screw Chart.
• Graphics board cables and I/O board cable use mezzanine connectors, which require special handling and a mezzanine connector removal tool (see 'Mezzanine Connectors' in General Take Apart Information).
• After reassembling a Mac Pro (Late 2013) for a graphics board or CPU riser card repair, you must run Cooling System Diagnostic (CSD) to ensure correct thermal operation.

General Troubleshooting

Update Software and Firmware

Important: Before you begin troubleshooting, ensure the correct version of OS X is installed, and check for and apply the latest software and firmware updates. Computers sometimes exhibit symptoms that indicate the wrong version of OS X system software is installed. Check article HT204319: OS X versions and builds included with Mac computers to make sure system build is correct for this computer model.

Firmware is the name given to software that is written into memory circuits such as flash memory, that will hold the software code indefinitely, even when power is removed from the hardware. Firmware on Intel Mac computers is designed to be updated if necessary by running the OS X Software Update check (available in the Apple ( ) menu) while computer is connected to the Internet.

For more information about firmware updates, refer to articles HT1557: About firmware updates for Intel-based Macs and HT201518: About EFI and SMC firmware updates for Intel-based Mac computers.

Troubleshooting Theory

More information about troubleshooting theory is located online at atlaslms.apple.com. Sign in to the Apple Technical Learning Administration System (ATLAS) with your Apple ID and password and search for "troubleshooting."

Hardware vs. Software

To isolate a hardware issue from a software issue, refer to article HT203161: Isolating issues in Mac OS X.

To troubleshoot a software issue, refer to article HT201861: About incompatible software on your Mac.

Quick Check Procedures

The following procedures are often helpful in troubleshooting Mac Pro issues.

1. Resetting the System Management Controller (SMC)

• The SMC controls all power functions for the computer. If the computer is experiencing any power issue, resetting the SMC may resolve it. The SMC controls several functions, including:
• Telling the computer when to turn on, turn off, sleep, wake, and idle.
• Handling system resets from various commands.
• Controlling the fans.

Note that resetting the SMC does not reset the NVRAM (Non-Volatile Random-Access Memory) . Resetting the SMC will not resolve issues in which the computer is unresponsive. In these situations, restarting the computer generally works. If the computer isn't responding, perform these steps one at a time, in the following order, until the issue has been resolved.

• Force Quit (Option-Command-Escape)
• Restart
