Renewed Mac Pro desktops can suit buyers who need a compact Intel workstation, legacy macOS compatibility, or a broad set of Thunderbolt 2 connections—but these older cylindrical systems demand careful matching to the job. I rank the 12-core model first for heavily threaded work, the 64GB model as the strongest memory-and-storage package, and the 16GB model for buyers who want 512GB of flash storage without paying for unused capacity. Their shared limits matter: all three use aging Intel-era hardware, dual FireFire Pro D300 graphics, and a chassis with little internal expansion. The best choice comes down to whether you value CPU threads, memory headroom, or a simpler entry configuration most.

Key Takeaways
- The 12-core Mac Pro is the best fit here for workloads that can use many CPU threads, but its 256GB SSD leaves less room for local projects.
- The 64GB configuration pairs the largest listed memory capacity with a 512GB SSD, making it a better multitasking fit than either 16GB or 32GB models.
- The 16GB model offers a 512GB SSD and quad-core processor, but memory-heavy work may feel constrained sooner than on the other two.
- All three share dual AMD FirePro D300 graphics and six Thunderbolt 2 ports, so their strongest differences are CPU, RAM, and storage rather than connectivity.
- These are renewed, older Intel workstations with listed Yosemite or Sierra-era software; buyers should check seller condition, warranty, and app compatibility before ordering.

More Details on Our Top Picks
Apple Mac Pro Desktop Computer, 12-Core Intel Xeon E5 2.7 GHz, 32 GB RAM, 256 GB SSD (Renewed)
I put this 12-core configuration first because it is the only option here built around a 12-core Xeon, making it the clearest choice for tasks that can distribute work across many CPU threads. Video exports, rendering, and parallel processing may benefit more from those cores than from the higher clock speed of the quad-core models. Compared with the 3.7GHz alternatives, this machine trades per-core speed for a wider pool of cores, so the advantage depends on the software and workload rather than the core count alone.
The rest of the configuration is more restrained. 32GB of ECC memory is a workable middle ground, though it sits below the 64GB model, and the 256GB flash drive is the smallest in this lineup. That leaves less room for applications, active projects, and media files before external storage becomes necessary. It shares the same dual D300 graphics and six Thunderbolt 2 ports as the other two picks, so I would choose it for CPU throughput, not because it has a more modern graphics or connection platform.
This listing does offer a useful reassurance that the other supplied descriptions do not spell out: certified refurbished condition and a minimum 90-day warranty. Generic packaging or accessories may still arrive, and a short warranty is not a substitute for checking return terms. The listed operating system is Mac OS X Yosemite, which signals that software compatibility needs attention. Buyers who primarily need abundant memory or local storage should favor the 64GB model; buyers whose tasks rarely use many cores may get a better fit from a faster-clocked quad-core option.
Pros:- 12-core Xeon can suit well-threaded workloads
- 32GB of ECC memory is a balanced workstation baseline
- Dual FirePro D300 graphics and six Thunderbolt 2 ports
- Listing specifies certified refurbishment and a minimum 90-day warranty
Cons:- 256GB SSD is the smallest internal drive in the lineup
- 2.7GHz processor speed is lower than the quad-core models’ listed 3.7GHz
- Yosemite-era software and older hardware may restrict modern app compatibility
Best for: Buyers running legacy or specialist applications that can use many CPU cores and who are comfortable keeping large files on external storage.
Not ideal for: People who need a large internal project drive, current software support, or a configuration with the most memory in this comparison.
- Processor:12-core Intel Xeon E5, 2.7GHz
- Memory:32GB 1866MHz DDR3 ECC
- Storage:256GB PCIe flash
- Graphics:Dual AMD FirePro D300, 2GB GDDR5 each
- Ports:Six Thunderbolt 2, four USB 3.0
- Wireless:802.11ac Wi-Fi and Bluetooth 4.0
- Operating system:Mac OS X Yosemite
- Renewal details:Certified refurbished; minimum 90-day warranty
Our verdict“Choose this renewed Mac Pro when multi-core CPU capacity matters more than internal storage or the highest listed memory.”
Apple Mac Pro Quad Core 3.7GHz Xeon (ME253LL/A) 64GB RAM, 512GB Solid State Drive (Renewed)
This configuration ranks second because its combination of 64GB ECC memory and a 512GB SSD is the most generous overall package for keeping active work local and avoiding memory pressure. Compared with the 12-core model, it has four cores rather than twelve, but twice the listed memory and twice the storage. That makes it a more natural fit for users who keep several large applications or datasets open, while the 12-core model remains the stronger candidate for work that scales across many CPU threads.
The 3.7GHz quad-core Xeon is also clocked higher than the 12-core option’s listed 2.7GHz speed. That alone does not settle performance—the applications, core use, and system condition all matter—but it helps explain why this is not simply a lower-tier version of the 12-core Mac Pro. Its dual FirePro D300 GPUs and six Thunderbolt 2 ports match the other models, giving it substantial legacy peripheral connectivity without offering a newer graphics platform.
The tradeoff is the same cylindrical design shared across this roundup: limited internal expansion. The supplied listing gives a 64GB memory configuration but does not detail renewal warranty coverage, so I would confirm the exact condition, return policy, and included accessories with the seller. It lists macOS Sierra, newer than the Yosemite entries here, though that does not guarantee support for current applications. Compared with the 16GB model, this pick is much better prepared for memory-intensive work; compared with the 12-core model, it sacrifices parallel CPU capacity. It makes the most sense when RAM and a larger internal SSD are the priorities.
Pros:- 64GB of ECC memory is the largest capacity in this comparison
- 512GB SSD provides more local workspace than the 12-core model
- 3.7GHz quad-core Xeon offers a higher listed clock speed than the 12-core option
- Six Thunderbolt 2 ports, four USB 3.0 ports, HDMI, and dual Ethernet
Cons:- Four cores are a weaker fit for workloads that scale across many threads
- Compact cylinder limits internal expansion
- Renewal warranty details are not specified in the supplied listing
Best for: Users who run several demanding applications at once, work with sizable datasets, or prefer more internal SSD space and memory over maximum CPU core count.
Not ideal for: Buyers focused on heavily threaded rendering or those who need a modern, readily expandable workstation with clearly specified warranty coverage.
- Processor:3.7GHz quad-core Intel Xeon E5
- Memory:64GB 1866MHz DDR3 ECC
- Storage:512GB SSD
- Graphics:Dual AMD FirePro D300, 2GB GDDR5 each
- Ports:Six Thunderbolt 2, four USB 3.0, HDMI
- Networking:Dual Gigabit Ethernet
- Operating system:macOS Sierra
- Form factor:Compact cylindrical workstation; listed as 11 pounds
Our verdict“I recommend this configuration for buyers who value abundant ECC memory and a larger SSD more than a 12-core processor.”
Apple Mac Pro Desktop Computer, 3.7 GHz Quad-Core Intel Xeon E5, 16 GB RAM, 512 GB SSD (Renewed)
The 16GB model is the straightforward pick for buyers who want the familiar 3.7GHz quad-core Mac Pro platform and a 512GB PCIe flash drive without needing the 64GB configuration. Its processor and storage capacity match the 64GB model’s headline figures, but memory is reduced to a quarter of that option. Against the 12-core model, it has fewer CPU cores but twice the listed SSD capacity. That puts it in a narrower role: a fit for lighter legacy workstation tasks where internal storage matters more than extra cores or extensive multitasking headroom.
Like its siblings, it includes dual AMD FirePro D300 graphics, Wi-Fi, Bluetooth 4.0, six Thunderbolt 2 ports, and four USB 3.0 ports. This shared hardware can be useful for an established desk setup with older high-speed peripherals, but it does not erase the platform’s age. The listing names OS X Yosemite, and buyers should verify whether the exact apps and devices they rely on will work with that software environment. I would not select it for a demanding modern workflow simply because its SSD is fast or its ports are plentiful.
The central limitation is 16GB of memory, which may leave less room for simultaneous applications, large creative projects, and memory-hungry tools than either rival. Compared with the 64GB Mac Pro, this is a leaner configuration; compared with the 12-core version, it gives up eight cores while retaining more storage. Renewal condition details in the supplied description are limited, so check seller coverage and return terms. I rank it third not because it lacks useful connectivity, but because its combination of modest memory and older software is the least flexible for workstation buyers.
Pros:- 512GB PCIe flash storage matches the larger-storage option in the lineup
- 3.7GHz quad-core Xeon is suited to compatible legacy workstation tasks
- Dual FirePro D300 graphics and six Thunderbolt 2 connections
- Includes Wi-Fi, Bluetooth 4.0, and four USB 3.0 ports
Cons:- 16GB of memory is the lowest capacity in this comparison
- Four CPU cores trail the 12-core model for parallel workloads
- OS X Yosemite and renewed condition call for careful compatibility and seller checks
Best for: Buyers with a specific need for an Intel Mac Pro and legacy software who expect modest multitasking and want 512GB of internal flash storage.
Not ideal for: People working with large datasets, many simultaneous applications, current demanding creative software, or CPU-heavy rendering tasks.
- Processor:3.7GHz quad-core Intel Xeon E5
- Memory:16GB 1866MHz DDR3 ECC
- Storage:512GB PCIe flash
- Graphics:Dual AMD FirePro D300, 2GB GDDR5 each
- Ports:Six Thunderbolt 2 and four USB 3.0
- Wireless:Wi-Fi 802.11a/b/g/n/ac and Bluetooth 4.0
- Operating system:OS X Yosemite
- Dimensions:9.9 inches tall, 6.6 inches in diameter
Our verdict“Pick this Mac Pro only when its 512GB drive and legacy Intel platform fit a modest workload better than extra cores or memory.”
How We Picked
I ranked these renewed Mac Pro desktops around the practical choices a buyer faces: processor capacity, memory, storage, software age, and renewal safeguards. Since all three listings describe the compact cylindrical Intel Mac Pro with dual FirePro D300 graphics and extensive Thunderbolt 2 connectivity, those shared features do not decide the order by themselves. I gave the 12-core configuration the lead for CPU-heavy work because it offers substantially more processing cores than the quad-core alternatives. I placed the 64GB option next for buyers who need to keep larger workloads in memory while retaining 512GB of SSD space. The 16GB version comes third: its 512GB flash drive is useful, but its memory ceiling is the most immediate compromise for workstation multitasking.
I also treat renewal details as part of the buying decision, not as a footnote. One listing specifies certified refurbishment and a minimum 90-day warranty; the others identify the computers as renewed but do not give the same warranty detail in the supplied information. That difference may matter more than a small spec advantage if dependable condition coverage is a priority. I have not assumed that an older Mac Pro will support every current application or macOS release. Buyers should verify the seller’s exact configuration, included accessories, return terms, and software needs before choosing.
| renewed mac pro desktop | Ports | Operating system |
|---|---|---|
| Apple Mac Pro Desktop Computer | Six Thunderbolt 2, four USB 3.0 | Mac OS X Yosemite |
| Apple Mac Pro Quad Core 3.7GHz | Six Thunderbolt 2, four USB 3.0, HDMI | macOS Sierra |
| Apple Mac Pro Desktop Computer | Six Thunderbolt 2 and four USB 3.0 | OS X Yosemite |
Factors to Consider When Choosing Renewed Mac Pro Desktops
These renewed Mac Pros share a distinctive compact chassis and many of the same ports, so I would start with the workload rather than the exterior. The main decision is whether your work needs more CPU cores, more memory, or a larger local SSD. Then check software compatibility and the terms attached to the renewed unit.
Match processor cores to your applications
The 12-core Xeon is the standout when software can distribute a task across many cores. Rendering, encoding, or other parallel jobs may make better use of it than a lightly threaded application. The quad-core models list a faster 3.7GHz clock, compared with 2.7GHz for the 12-core configuration, but clock speed alone cannot predict how a particular application will perform. I would look up the exact software’s CPU requirements and real-world scaling behavior before choosing. If the work is mostly basic office use or a narrowly defined legacy task, paying for extra cores may bring little practical benefit.
Choose memory for the workload you actually run
The three configurations span 16GB, 32GB, and 64GB of ECC DDR3 memory. More RAM gives applications room to keep larger files and datasets active and can reduce reliance on slower storage when multiple tasks run together. The 64GB version is the clearest choice for memory-heavy multitasking; 32GB offers a middle ground alongside the 12-core CPU. The 16GB option is the most restricted and belongs with light or tightly controlled workloads. Because this is an older cylindrical design with limited internal expansion, do not assume you can easily correct a memory mismatch later; verify upgrade options for the precise model.
Treat SSD capacity and external storage as a pair
The 12-core unit has a 256GB PCIe flash drive, while the two quad-core configurations list 512GB. The smaller drive can become crowded if it holds the operating system, applications, and active project files together. External storage can help, especially with the Mac Pro’s Thunderbolt 2 connections, but it adds another device and may not suit every mobile or tidy-desk setup. If your projects are large, compare the cost and practicality of external storage with the convenience of a bigger internal SSD. Also confirm the listing’s exact storage type and usable capacity with the seller.
Check legacy software and peripheral needs
The supplied listings identify Yosemite or Sierra-era operating systems, and all three are Intel workstations from an older generation. That can be an advantage for a buyer maintaining a specific legacy app, but it can create barriers for current software, security updates, or newer accessories. Confirm that the operating system can run the exact apps you need and that required plug-ins, drivers, and devices are supported. Thunderbolt 2, USB 3.0, HDMI, and dual Ethernet offer several connection paths, yet older ports may require adapters for newer equipment.
Read renewed-condition terms before ordering
Renewed units can differ in wear, packaging, accessories, and warranty coverage. Only the 12-core listing in this comparison explicitly states certified refurbishment and a minimum 90-day warranty; the supplied details for the other models do not specify equivalent coverage. I would check the seller’s written condition description, included power cable and accessories, return window, and any warranty exclusions. A renewed workstation is a sensible purchase only when its condition and support terms are clear enough for the role it will serve.
Frequently Asked Questions
Which renewed Mac Pro is best for processor-heavy work?
I would start with the 12-core model for software that can use many CPU threads. It has far more cores than either quad-core option, though its 2.7GHz listed speed is lower and its SSD is only 256GB. Check that your application scales well across cores; a larger core count is not a universal advantage for every task.
Which configuration has the most memory and storage?
The 3.7GHz quad-core model with 64GB RAM has the largest memory capacity and includes a 512GB SSD. It is the strongest fit here for memory-heavy multitasking paired with a larger internal drive. It does not match the 12-core option for core count, so CPU-heavy buyers may prefer that alternative.
Are these renewed Mac Pros suitable for current macOS applications?
Do not assume that they support every current application or operating system release. The supplied listings name Yosemite or Sierra-era software, and app requirements change over time. Before buying, check the exact macOS support for each essential application, plug-in, and peripheral, as well as the seller’s description of the installed system.
Is 16GB of RAM enough for a renewed Mac Pro?
It can be enough for light work or a specific older application with modest memory needs, but it is the most limiting configuration in this comparison. Buyers who keep multiple demanding programs open or work with large projects should favor 32GB or 64GB. Confirm whether the exact model permits a practical memory upgrade rather than relying on that possibility.
What should I verify about a renewed unit before purchasing?
I would verify the computer’s exact processor, memory, storage, graphics, and installed operating system, then read the condition, warranty, and return details. Check whether power and other necessary accessories are included, since renewed listings may use generic packaging or accessories. The 12-core listing states a minimum 90-day warranty; the other supplied descriptions do not give the same warranty detail.
Conclusion
For CPU-heavy legacy work, I would choose the 12-core Mac Pro, provided its 256GB SSD is enough or external storage fits the setup. For memory-intensive multitasking, the 64GB model is the better match, with twice the storage of the 12-core option and much more RAM than the entry configuration. For lighter tasks that need a 512GB drive, the 16GB quad-core model is the more modest option, though its limited memory makes it the least flexible choice. I would buy any of them only after confirming app compatibility and the renewed seller’s condition, warranty, and return terms.
