iMac 2013: the newest macOS it can run
Every iMac sold in 2013, what Apple supports, what OpenCore Legacy Patcher adds, and what to expect on each macOS version. Generated from the OCLP 3.0.0 source.
On this page 6 sections
Short answer
Apple stopped at macOS Catalina. With OpenCore Legacy Patcher the iMac 2013 runs macOS Big Sur through macOS Tahoe 26. Our pick for most people: macOS Sequoia. No Intel Mac can run macOS 27.
Which iMac 2013 do you have?
Apple sold 4 different models as the iMac 2013. They can behave differently with OCLP, so check your model identifier: choose Apple menu > About This Mac, then More Info > System Report, and read Model Identifier. Or open Terminal and run sysctl hw.model
| Identifier | Sold as | Graphics | Apple's last macOS | OCLP |
|---|---|---|---|---|
iMac13,3 | iMac (21.5-inch, Early 2013) | Intel HD Graphics 4000 (Ivy Bridge) | Catalina | Yes |
iMac14,1 | iMac (21.5-inch, Late 2013) | Intel Iris / HD (Haswell) | Catalina | Yes |
iMac14,2 | iMac (27-inch, Late 2013) | Intel Iris / HD (Haswell) NVIDIA GeForce GT 6xx/7xx (Kepler) | Catalina | Yes |
iMac14,3 | iMac (21.5-inch, Late 2013) | Intel Iris / HD (Haswell) NVIDIA GeForce GT 6xx/7xx (Kepler) | Catalina | Yes |
macOS versions compared
- 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

OCLP treats this model exactly like iMac14,2: the same CPU, graphics, Wi-Fi and Bluetooth data, the same root patches on every macOS, and the same kexts in our build. What differs: board ID Mac-77EB7D7DAF985301 instead of Mac-27ADBB7B4CEE8E61 and sold as iMac (21.5-inch, Late 2013). The macOS table, patch timeline and build details above apply unchanged.

Installing on the iMac 2013
Choose iMac13,3 or iMac14,1 or iMac14,2 or iMac14,3 as the target model when OCLP builds OpenCore (it detects it automatically when you run OCLP on this Mac). Before that, install the newest macOS Apple offers for it, macOS Catalina, so the firmware is current. The steps themselves are the same for every Mac: How to install OpenCore Legacy Patcher.
