macOS

I am currently running a dual-boot macOS/arch linux on my ThinkPad X1 Carbon 5th Generation. My system specs are as follows:

• OS: macOS Sierra 10.12.6
• Model: Lenovo ThinkPad X1 Carbon 5th Generation
• CPU: Intel i7-7600U @ 3.9GHz
• GPU: Intel HD Graphics 620
• Memory: 16GB
• Storage: 500GB Samsung 850 SATA SSD
• Wifi-Card: Broadcom BCM94352Z DW1560

I use arch linux as my main OS and reserve macOS for compatibilty tasks such as Microsoft Office, XCode, and presentations.

To achieve this dual boot, I am using a dual EFI System partition setup. I use Clover to launch macOS and GRUB to launch arch linux. The system defaults to launching GRUB, where I can boot into either arch linux directly or into Clover, from where I can then launch macOS.

System Bootloader -> GRUB -> CLOVER -> macOS
                      |
                      V
                  arch linux

To achieve this chainloading, I am using the 40_custom defined in this directory.
