Description of problem: In macOS, System Preferences > Startup Disk panel doesn't show Fedora anymore. The firmware boot manager does show it. Version-Release number of selected component (if applicable): macOS 10.12.3 mactel-boot-0.9-13.fc24.x86_64 How reproducible: Always with these versions Steps to Reproduce: 1. macOS installed > Fedora installed (both default installations) 2. boot macOS 3. System preferences > Startup disk panel Actual results: Only macOS shows up as a boot option. Expected results: macOS and Fedora should show up as boot options. Regression testing: Problem doesn't happen with: Fedora-Live-Desktop-x86_64-20-1.iso Fedora-Live-Workstation-x86_64-23-10.iso Problem first appears with Fedora-Workstation-Live-x86_64-24-1.2.iso and persists in Fedora 25 and Rawhide.
Created attachment 1258247 [details] macOS startup panel, F23 macOS 10.12.3 (Sierra) and Fedora 23. Screenshot shows that macOS sees the F23 ESP, however apparently something is new in macOS where it doesn't actually like something about it (no real kernel, and no way to build boot cache, functionally the same thing as initramfs on Linux). And NVRAM is not modified to boot Fedora as a result.
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle. Changing version to '26'.
This message is a reminder that Fedora 26 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '26'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 26 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 26 changed to end-of-life (EOL) status on 2018-05-29. Fedora 26 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
