A message from vit9696

This month completes the vacation season, and this time we have something special to present. For a long time Linux support was a grey area in OpenCore. It worked and we fixed the reported issues when it did not. However, one needed to perform a fair amount of work to make Linux natively display in the OpenCore boot pickers, whether built-in or the shiny OpenCanopy. This fall, this is finally changing.

With OpenCore 0.7.3, we present a preview version of the OpenLinuxBoot.efi driver, which delivers first-class Linux support for OpenCore without any chainloading required like GRUB or rEFInd. @MikeBeaton did a really great job on this. His driver supports all sorts of distributions, including blspec compatibility, automatic detection of other installation types / schemes, and even manual configuration for particularily peculiar setups. There is a comprehensive section on how to use it in the reference manual, as well as in the discussion for the PR. While we have had positive experiences so far, we must still warn you that the driver has just landed and is still in a beta stage.

Among other bootloader changes there are several stability fixes, new quirks for older hardware courtesy of @mhaeuser, and security revampments by @MikhailKrichanov. As for the drivers, WhateverGreen got a long awaited backlight smoothing support for the Intel GPUs thanks to @0xFireWolf. After months of hard work from @Goldfish64 AppleALC and VirtualSMC are now available on 32-bit macOS versions up to 10.4 for the first time. To add more, VoodooPS2 also received support for the touchpad muxers thanks to @1Revenger1.
