Apple has rolled out a firmware update, called the EFI Firmware Update v1.8, for the Mac mini. The update will fix an issue related to the USB keyboard.

Apple recommends the update to all late-2012 Mac mini owners. The company is encouraging users of the Mac mini to download the latest firmware update, which weighs only 4.8MB.

"This update is recommended for Mac mini (late 2012) models. This update addresses an issue that may prevent a USB keyboard from being recognized after the system wakes from sleep," stated the Apple support page.

Although the firmware is meant for late-2012 Mac mini units, other iterations may also be affected. The firmware is available as a free update from the Software Update system of the Mac mini or via Apple's support website.

Apple confirmed the update on Wednesday, July 15. It is not, however, the first firmware update that the Mac mini has received since its launch. In December 2012, Apple released the first update that addressed the video flickering issue.

"This update addresses HDMI video flicker issues on Mac mini (Late 2012) computers and is recommended for all users," said Apple.

Apple has not made any design changes to the Mac mini. In 2014, the company enhanced some specs of the Mac mini but the external form factor remained the same.

"Mac mini is an affordable powerhouse that packs the entire Mac experience into a 7.7-inch-square frame. Just connect your own display, keyboard, and mouse, and you're ready to make big things happen,"Apple touted.

The latest 2014 Mac mini has a starting price tag of $499. The base model of the Mac mini includes a 1.4GHz dual-core Intel Core i5 processor with Turbo Boost up to 2.7GHz, 500GB internal storage and 4GB RAM.

The Mac mini can support up to two displays at 2,560 x 1,600 pixels resolution.
