• Dual Gigabit Ethernet
• HDMI 1.4 Ultra HD

      Wireless

• 802.11ac Wi-Fi wireless networking; IEEE 802.11a/b/g/n compatible
• Bluetooth 4.0 wireless technology ^ [Amazing network speeds]! ^

      Electrical and Operating Requirements

• Line voltage: 100-240V AC
• Frequency: 50Hz to 60Hz, single phase
• Maximum continuous power: 450W
• Operating temperature: 50 to 95 degrees F (10 to 35 degrees C)
• Relative humidity: 5c/o to 95c/o noncondensing
• Maximum altitude: 16,400 feet (5000 meters)
• Typical acoustical performance, sound pressure level (near operator): 12 dBA at idle

      In the Box

• Mac Pro, A/C Power Cord, Ethernet Cord, and HDMI Cable

      Included macOS Software

• macOS is the operating system that powers everything you do on a Mac and brings new features inspired by its most powerful users, but designed for everyone to get more out of every click. [Updated macOS, July 29, 24, latest macOS Monterey, vr 12.7.6 (21H1320)].

      Acoustic Performance

Declared noise emission values in accordance with ECMA-109

• Sound Power Level L_WA,m (B)
• Sound Pressure Level Operator Position L_pA,m (dB)
• Idle: 2.05 (K_V = 0.25), 14.0
• Wireless web: 2.05 (K_V = 0.30), 14.5

L_WA,m is the mean A-weighted sound power level, rounded to the nearest 0.05 B.
L_pA,m is the mean A-weighted sound pressure measured at operator (rounded to nearest 0.5 dB).
1 B (bel) = 10 dB (decibel) K_V is statistical adder computing upper-limit A-weighted sound power.
The quantity, L_WA,c (formerly called L_WAd) may be computed from the sum of L_WA,m & K_V.

      Mac Pro and the Environment

Apple takes a complete product life cycle approach to determining our environmental impact.

• ENERGY STAR 6
• EPEAT Gold
• BFR-free
• PVC-free
• Highly recyclable
• Weight varies by configuration and manufacturing process.
• 1GB = 1 billion bytes and 1TB = 1 trillion bytes; actual formatted capacity less.
• Internet access required. 802.11ac is based on an IEEE draft specification.
• Mac Pro achieved a Gold rating from EPEAT in the U.S. and Canada.
• PVC-free power cord available in all regions except India and South Korea.
