The summer is drawing to a close, which means macOS Mojave is about to be released. It may also mean a few other things, but we’re going to concentrate on the release of Mojave and what you’ll need to do to your Mac to get it ready for the new operating system from Apple.

Mojave has a number of new features that you may be excited to try out, but it also has quite a few upgrades under the hood, which mean it’s especially important to ensure your Mac and its software are ready for macOS Mojave.

Upgrading to macOS Mojave

For this article, we’re going to concentrate on steps you should take to ensure your Mac is capable of running macOS Mojave, as well as make sure there are no hidden issues that could adversely impact installing or using the new operating system. We won’t be looking at the various ways you can install Mojave; we’ll cover that in the weeks ahead. So, let’s start by checking if your Mac is compatible.

Check Hardware Compatibility with macOS Mojave

The first step is to check to see if your Mac meets the minimum guidelines for running macOS Mojave. You can find details in OWC’s Complete List of Mojave Compatible Macs.

The main takeaway from the compatibility list is that Apple has dropped support for most Macs older than 2012. The main exception is 2010 and 2012 Mac Pro models that have Metal-capable graphics cards. The original graphics cards offered with the early Mac Pros weren’t Metal compatible, but it’s possible to upgrade the graphics card with a new Metal-compatible model.

Apple recommends the following Metal-compatible cards:

  • MSI Gaming Radeon RX 560
  • Sapphire Radeon PULSE RX 580

But there are a number of other graphics cards available that will work with your Mac Pro and support Metal:

  • AMD: Radeon HD 7000 and HD 8000, as well as the 200, 400 and 500 series of cards.
  • NVIDIA: Most GeForce 600, 700 and 800 series.

XFX AMD Radeon RX 580 GTS is one of the Metal-capable graphics cards you can use with a 2010-2012 Mac Pro.

One issue you may encounter with a new Metal-capable graphics card is that it likely won’t contain a Mac-compatible boot ROM on the card. Without the boot ROM that supports the Mac, the graphics card won’t be initialized until after the Mac loads the graphics drivers. This can prevent boot up information from being displayed, including running firmware updates (should any become available) or using boot options that require any type of interaction.

To overcome the boot ROM issue, you can either attempt to locate a graphics card with an Apple boot ROM or keep the original graphics card installed and connected to a second monitor.

One last note on Metal graphics cards: AMD models come with Apple graphics drivers built in, while NVIDIA models do not. This means you’ll need to download and install the Mac graphics drivers from the NVIDIA website before the card will work correctly.

You may also need to update NVIDIA drivers before you upgrade to any new version of the macOS, such as Mojave.
