Apple details Mojave support on Mac Pro, says some iMacs won’t support Boot Camp after update

Following the release of macOS 10.14 Mojave this afternoon, Apple has published a pair of support documents with details for specific machines. These documents relate to installing Mojave on older Mac Pro machines, as well as Boot Camp support on select iMacs.

First off, Apple outlines the graphic cards that support Metal and are therefore compatible with macOS Mojave on the mid-2010 and mid-2012 Mac Pro models:

  • MSI Gaming Radeon RX 560 128-bit 4GB GDRR5
  • SAPPHIRE Radeon PULSE RX 580 8GB GDDR5
  • SAPPHIRE Radeon HD 7950 Mac Edition
  • NVIDIA Quadro K5000 for Mac
  • NVIDIA GeForce GTX 680 Mac Edition

Apple says that “some other third-party graphics cards” based on certain AMD GPU families “might” also be compatible with Mojave on the mid-2010 and mid-2012 Mac Pro models:

  • AMD Radeon RX 560
  • AMD Radeon RX 570
  • AMD Radeon RX 580
  • AMD Radeon Pro WX 7100
  • AMD Radeon RX Vega 56
  • AMD Radeon RX Vega 64
  • AMD Radeon Pro WX 9100
  • AMD Radeon Frontier Edition

The company notes, however, “third-party graphics cards vary, so you should check with the vendor of your specific graphics card for compatibility details.”

Meanwhile, in a separate support document, Apple explains that if you have a late-2012 27-inch iMac with a 3TB hard drive, you’ll have to ditch your Boot Camp partition in order to upgrade to macOS 10.14 Mojave.

After installation, you won’t be able to use Boot Camp to install Windows. Thus, you’ll have to rely on a virtualization option such as Parallels.

If you have an iMac (27-inch, Late 2012) with a 3TB hard drive, you must remove its Boot Camp partition before you can install macOS Mojave 10.14. After you upgrade to macOS Mojave, you won’t be able to use Boot Camp to install Windows on this Mac.

The alert “Installation cannot proceed with Boot Camp configured” appears only when you try to install macOS Mojave 10.14 on iMac (27-inch, Late 2012) that has a 3TB hard drive with an existing Boot Camp partition.

To install macOS Mojave on this iMac, first back up your Windows data, then use Boot Camp Assistant to remove the Boot Camp partition. After the Boot Camp partition is gone, you can install macOS Mojave.
