To do this, boot from the installation media again and enter the rescue mode.
Reinstall grub (to avoid the booting-to-black-screen problem). When the installation finishes the system is not quite usable yet. Ignore the error and continue the installation. When starting the installation there will be an error about a missing mactel-boot package. Instead I used a package repository URL as the installation source, more specifically. In my case the package installation from install media was not possible. Click + repeatedly to create the rest of the partitions as usual ( /boot, /swap, /home, etc.). Create /foo mountpoint, 600M, Standard partition, then edit the partition to be on /boot/efi and change the file system to 'EFI System Partition'. Done in the top left to get to the partitioning screen. Select "Custom" (I didn't try automatic, but it probably would not create the EFI partition). At the bottom, click the "Full disk summary and boot loader" text. 
Here are the relevant steps, slightly adjusted: However we have to do some custom partitioning. Installing CentOS is relatively straight forward. Remember to adjust the values in mount-lvm.sh to your environment. Alternatively you type the commands in the script manually in step 3. Copy repair-grub.sh and mount-lvm.shĬopy the contents of repair-grub.sh and mount-lvm.sh onto the installation media. By default it expects a certain name for the volume, depending on the ISO you used.ġ.5.
Fix the grub.cfg file to use your name. Create a EFI boot image that does not result in a black screen but actually gets you into grub. Copy its contents to the installation media. The script will perform the following actions in a docker container: Use the GUID partition table (apparently some macs are especially picky about this setting).Įdit the create-ush.sh script with your name and the location of the CentOS ISO file. Format the volume with a FAT filesystem. On a Mac however I erased the USB drive using Disk Utility: If you are using a Linux machine you can probably skip steps 1.1 and 1.2 and instead copy the contents of the ISO to the USB drive using dd. 
By default the system wasn't able to read the filesystem of the CentOS ISO or the drive created by Etcher. This step is mainly necessary in order to be able to modify files on the USB drive in macOS.
Copy repair-grub.sh and mount-lvm.sh to the USB drive. In order to successfully get to the CentOS installer I did the following things: by using balenaEtcher) I was greeted by a black screen. When using the usual methods of creating a bootable USB drive (e.g. Tested using CentOS Stream 8 on a Late 2014 Mac Mini. In this snippet I gather my findings and present a way to successfully install CentOS on a Mac. I repeatedly had issues even getting the installation media to boot. Installing recent CentOS versions on Macs is not as straight forward as I wish it to be.
