Mac Pro: which macOS each year can run
Every Mac Pro from 2008 to 2019: Apple's last macOS and what OpenCore Legacy Patcher adds. OCLP supports Mac Pro models from 2008 to 2013.
On this page 7 sections
| Year | Model identifiers | Apple's last macOS | With OCLP |
|---|---|---|---|
| Mac Pro 2008 | MacPro3,1 | El Capitan | Big Sur → Tahoe |
| Mac Pro 2009 | MacPro4,1 | El Capitan | Big Sur → Tahoe |
| Mac Pro 2010–2012 | MacPro5,1 | Mojave | Big Sur → Tahoe |
| Mac Pro 2013 | MacPro6,1 | Monterey | Big Sur → Tahoe |
| Mac Pro 2019 | MacPro7,1 | Tahoe | Not supported (T2) |
Every Mac Pro at a glance
- Apple supported by Apple, no patcher needed
- runs with OpenCore Legacy Patcher
- runs with OCLP; older “legacy Metal” GPU, more patches
- runs with OCLP; GPU without Metal, apps that need Metal fail
- No not possible

How the Mac Pro hardware changed, year by year
Each line compares a year with the one before it, using the CPU, graphics, Wi-Fi and root-patch data in OCLP's source. It shows why one year behaves differently from its neighbour.
- 2008 → 2009: CPU: Core i (Nehalem/Westmere) replaces Core 2 Duo (Penryn); graphics: NVIDIA GeForce (Tesla) replaces ATI Radeon HD 2000–4000 (TeraScale 1); Wi-Fi: Atheros (AirPortAtheros40) replaces Broadcom BCM43224 (legacy); Tahoe root patches: new Nvidia Tesla; no longer AMD TeraScale 1.
- 2009 → 2010–2012: graphics: AMD Radeon HD 5000–6000 (TeraScale 2) replaces NVIDIA GeForce (Tesla); Wi-Fi: Broadcom BCM4331 (legacy) replaces Atheros (AirPortAtheros40); Apple's last macOS moves from El Capitan to Mojave; Tahoe root patches: new AMD TeraScale 2; no longer Nvidia Tesla.
- 2010–2012 → 2013: CPU: 3rd-gen Core i (Ivy Bridge) replaces Core i (Nehalem/Westmere); graphics: AMD Radeon / FirePro (GCN 1) replaces AMD Radeon HD 5000–6000 (TeraScale 2) and AMD Radeon Pro 400/500 (Polaris); Wi-Fi: Broadcom BCM4350/4360-class (AirportBrcmNIC) replaces Broadcom BCM4331 (legacy); Apple's last macOS moves from Mojave to Monterey; Tahoe root patches: new AMD Legacy GCN and Modern Wireless; no longer AMD Polaris, AMD TeraScale 2, Legacy USB 1.1 and Legacy Wireless.
- 2013 → 2019: CPU: 8th/9th-gen Core (Coffee Lake) replaces 3rd-gen Core i (Ivy Bridge); graphics: AMD Radeon Pro 400/500 (Polaris), AMD Radeon Pro 5000 (Navi) and AMD Radeon Pro Vega replaces AMD Radeon / FirePro (GCN 1); Wi-Fi: Broadcom (T2-era) replaces Broadcom BCM4350/4360-class (AirportBrcmNIC); Apple's last macOS moves from Monterey to Tahoe; Tahoe root patches: no longer AMD Legacy GCN, Modern Audio and Modern Wireless.
Where Mac Pro owners report trouble
58 issues in OCLP's tracker were filed with a Mac Pro model as the machine model; 1 supported Mac Pro model has no report at all. By keyword match, the topics that come up most are install or update (28), graphics (17), black screen or boot failure (12) and sleep and power (6). The models with the most reports: Mac Pro (Mid 2010) MacPro5,1 (39), Mac Pro (Early 2008) MacPro3,1 (12) and Mac Pro (Early 2009) MacPro4,1 (7). These are owners' reports, not confirmed bugs, and most were filed in 2021 and 2022 on early OCLP versions.
Mac Pro 2008
Short answer
Apple stopped at OS X El Capitan. With OpenCore Legacy Patcher the Mac Pro 2008 runs macOS Big Sur through macOS Tahoe 26. Our pick for most people: macOS Sequoia. No Intel Mac can run macOS 27.

Short answer
MacPro7,1 runs macOS Tahoe with Apple's support, so you do not need OpenCore Legacy Patcher. Tahoe is the last macOS for Intel Macs: macOS 27 does not support any Intel Mac.

No issue in OCLP's tracker was filed with MacPro7,1 as the machine model (searched 2026-11-05), so there is no owner feedback to summarise for this exact model.
Installing a newer macOS on these models
Update the firmware first by installing the newest macOS Apple offers for your model, back up, then follow How to install OpenCore Legacy Patcher: build OpenCore for your model identifier, create the installer on a USB drive, install, then run Post-Install Root Patch.
Memory
Macs with 2 GB of memory cannot install macOS Sonoma or newer (Dortania, Supported Models). Upgrade the memory first if your Mac allows it.Keep going
