- ArcaOS 5.0.6
- Installation Issue
ArcaOS can not be installed due to this error on the installation phase.
- Explanation
- It seems to be an issue related to UEFI CSM. The same error message shows on older MacBooks with a CSM in the UEFI firmware. Seems to be an issue on the "MemDisk" component.
- Workaround
- Remove the HDD device from that machine, install ArcaOS on a different machine with that HDD and reinstall the HDD back on the original machine.
- Additional Comments
- It seems this issue may be solved on ArcaOS 5.1 with formal UEFI support.
