This model also allows users to upgrade RAM and add more storage.

This Mac Pro 2019 model comes with a sleek Magic Keyboard and Magic Mouse 2, with an option for Magic Trackpad 2, offering smooth input options for users. It offers multiple connectivity options: 2 USB 3.0, 4 Thunderbolt 3, 2 HDMI 2.0, 2 10 Gb Ethernet, and a headphone jack. The device also supports wireless standards 802.11ac Wi-Fi and Bluetooth 5.0, allowing connectivity expansion through PCIe slots.\

This Mac Pro comes with MacOS X 10.15.1 (19B88) installed on it, offering professional users a high-performance system ready for use.

Common questions

Is the order number the same as A2304?

Not exactly. The order number usually points to a specific retail configuration, while A2304 identifies the broader Apple hardware family. Always check the EMC and model identifier too.

What Mac Pro is model A2304?

A2304 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 3413 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.
