EFI and SMC firmware updates for Intel-based Macs
Summary
This article lists firmware updates that were released for Intel-based Macs.
Products Affected
Mac Pro, Mac mini, MacBook, MacBook Air, MacBook Pro, Xserve, iMac
This article lists firmware updates that were released for Intel-based Macs. They update the firmware that originally shipped from the factory. If your computer does not appear on this list, an update from the factory firmware is not necessary.
Some firmware updates for Intel-based Macs may not be displayed automatically using Software Update. If they do not appear in Software Update, they must be manually downloaded from the Apple Downloads site. If you are unsure whether your computer needs a particular update, simply download and open the update installer. The installer will alert you if the firmware update is already installed or not needed.
Check your computer's EFI Boot ROM or SMC firmware version.
- From the Apple () menu, choose About This Mac.
- Click More Info.
- For OS X Lion and OS X Mountain Lion, click System Report. For Mac OS X Snow Leopard and earlier, proceed directly to step 4.
- Open the Hardware section to reveal Model Identifier, Boot ROM version, and SMC version numbers.
- The version information is in the pane on the right, as in this image:
Available firmware updates
Use this table to find available firmware updates for your Intel-based Mac; locate your model identifier in the table below to find out if an update is available for your computer.
Note: In some cases System Profiler may report later versions of firmware than those listed below; if this is the case, your computer does not require any additional firmware updates. If your firmware version is lower than the one listed in this table, you should upgrade by following the link provided.
