macOS Mojave System Requirements and Compatibility Guide

What macOS Mojave Requires and How to Verify Compatibility

macOS Mojave is an Apple operating system release that generally requires an Intel-based Mac introduced in 2011 or later, meeting minimum specifications for processor, memory, storage, and firmware. Supported Macs include selected iMac, MacBook, MacBook Air, MacBook Pro, Mac mini, and Mac Pro models listed by Apple as compatible with Mojave. Mojave does not run on Macs with Apple silicon (M1, M2, M3 and later). Understanding processor generation, available RAM, boot drive capacity, and EFI firmware version helps you determine upgrade eligibility and avoid unexpected issues.

Official macOS Mojave Hardware Requirements

Apple specifies baseline hardware that must be met for a clean install or in-place upgrade to macOS Mojave (10.14). These requirements cover processor architecture, system memory, boot storage capacity, and specific Mac models. Meeting the minimum specification does not guarantee ideal day-to-day performance, but it ensures the operating system can start and provide core functionality. If your Mac is listed by Apple as compatible, it should meet these requirements, though actual usability also depends on workload, peripherals, and remaining free space.

macOS Mojave Processor and Architecture Rules

macOS Mojave requires an Intel processor with a 64-bit architecture. Supported CPUs include 2nd generation Intel Core and later families, such as Sandy Bridge, Ivy Bridge, and Haswell. Processors must support features like NX, SSE4.2, and related instruction sets enabled by macOS. Macs with Apple silicon are not supported by Mojave and require waiting for ARM-based macOS releases. Use About This Mac > Overview to see the processor name and verify whether it aligns with the officially supported list.

Memory, Disk, and Firmware Criteria

macOS Mojave typically requires at least 2 GB of RAM for the operating system, but practical use with apps and background tasks often needs 8 GB or more. You need a boot volume with sufficient free space for system files, updates, and cached data; plan on multiple gigabytes available for updates and virtual memory. Firmware or T2 chip validation checks must pass, and certain Macs require a firmware update before installation. Mojave does not support Macs with Apple silicon (M1, M2, M3, etc). Examples are shown in the table below.

Compatible Mac Models Overview

macOS Mojave officially supports a broad range of Macs released from 2011 onward, covering consumer and professional tiers. Models are grouped by form factor and vary in upgrade paths and component availability. Mojave can be installed on these Macs via the Mac App Store or Recovery, provided they meet the hardware and firmware criteria. Apple silicon Macs are not compatible with Mojave.

Consumer and Pro Desktop and Notebook Models

• iMac (Mid 2011 or later)
• MacBook (Late 2011 or later)
• MacBook Air (Mid 2012 or later)
• MacBook Pro (Mid 2012 or later)
• Mac mini (Late 2012 or later)
• Mac Pro (Late 2013 or later, some Late 2008–2009 models supported with firmware updates)

How to Check Your Mac’s Mojave Readiness

You can determine your Mac’s eligibility by reviewing system details and running checks before downloading the installer. Use About This Mac for processor and memory details, System Information for storage controllers and firmware, and the Mac App Store or Recovery for install media. Confirm that your Mac model is listed as officially supported and that sufficient free space exists for the update.

Preparation and Pre-Installation Steps

Before upgrading or installing Mojave, back up important data using Time Machine or another method, verify account privileges (admin access is required), disconnect nonessential peripherals, and ensure a reliable power source. Confirm that updates for your Mac and firmware are current by opening Software Update. If you plan to perform an erase-install, ensure you can reinstall apps and restore files from backup.

Troubleshooting Common Requirements-Related Issues

Some users encounter issues where a Mac appears unsupported, fails to boot the installer, or cannot complete the upgrade due to firmware, disk, or memory constraints. Checking firmware version, ensuring EFI updates are applied, freeing up disk space, and confirming RAM compatibility can resolve many problems. If Installer says your Mac is not supported, you may need to verify the exact model and check whether a firmware update is available. Mojave does not support Macs with Apple silicon.

macOS Mojave Versus Later macOS Releases

macOS Mojave is an older major release that does not require the latest hardware, but it also does not include newer features and security updates introduced in Catalina, Big Sur, Monterey, Ventura, Sonoma, and later. Apple silicon Macs cannot run Mojave and require ARM-based macOS versions instead. Mojave remains useful for legacy software and specific workflows, yet for ongoing security and app compatibility, newer macOS releases are generally recommended when hardware permits.

Key Facts at a Glance

Summary

macOS Mojave requires a 64-bit Intel Mac from 2011 or later, at least 2 GB of RAM (8 GB recommended), and sufficient free boot storage, with supported desktop and notebook models listed by Apple. Apple silicon Macs are not supported by Mojave. Confirm model eligibility, firmware version, and available disk space before installing, and consider newer macOS releases for up-to-date security and app support. Proper preparation and checks reduce installation issues and ensure a stable upgrade.
