About this Mac Pro

The Mac Pro (ME253LL/A) in 2013 came with a radical change in its design as the tower form had been ditched for a cylinder form. There was a reduction of ports present, such as the total disappearance of FireWire Ports, but the power of the Mac Pro did not diminish in any way.

The a1481 Mac Pro “Quad Core” 3.7 (Late 2013) — is powered by a single 3.7 GHz Quad Core22-nm Xeon E5-1620v2 processor with a dedicated 256k of level 2 cache for each core and 10 MB of level 3 “Smart Cache.” By default, it was configured with 12 GB of 1866 MHz DDR3 ECC SDRAM, a 256 GB SSD, and dual AMD FirePro D300 graphics processors with 2 GB of GDDR5 memory each. This Mac Pro model can support up to 3 5K displays (5120×2880), two using Thunderbolt 2 ports and one using the HDMI port. The storage was changed from the conventional HDD to a 256 GB SSD with upgrades on purchase to 512 GB or 1 TB available at extra cost.

Connectivity includessix Thunderbolt 2 ports, one HDMI 1.4 UltraHD port, 4 USB 3.0 ports, and Dual Gigabit Ethernet ports in addition to 802.11ac and Bluetooth 4.0.

Common questions

Is ME2531LL/A the same as A1481?

Not exactly. ME2531LL/A usually points to a specific retail configuration, while A1481 identifies the broader Apple hardware family. Always check the EMC and model identifier too.

What Mac Pro is model A1481?

A1481 is the Apple A-number shown for this Mac Pro family. Use the order number, EMC, and model identifier on this page to narrow the exact configuration.

What does EMC 2630 mean?

The EMC number is another Apple hardware identifier. It helps separate closely related models that may share a similar name, year, or A-number.

Can the RAM or SSD be upgraded?

Check the spec table for the exact configuration. Many newer Apple Silicon Macs have memory and storage integrated into the board, so RAM and SSD upgrades are often not practical after purchase.

What macOS versions work with this model?

Use the model identifier, release year, and processor family from the spec table when checking macOS compatibility. Compatibility can change as Apple releases new macOS versions.

Is this Mac Pro still worth buying used?

It can be, depending on price, battery health, memory, storage, and condition. Compare this exact order number and model identifier against similar Techable listings before buying.

How much is this Mac Pro worth?

Value depends on RAM, storage, battery health, cosmetic condition, accessories, and market demand. Use the SellMac path on this page for a quote or use the identifiers here when comparing resale prices.

What should I search if this page is not the exact configuration?

Search the order number first when available, then compare the A-number, EMC, model identifier, year, chip, RAM, and storage. The same A-number can cover more than one configuration.
