I also never use Thunderbolt though I use the mini display port. Just to clarify that should we put acpi_osi=!Darwin, or acpi_osi="!Darwin"?

@melmeiro Honestly, I can't quite recall why I had to set acpi_osi=!Darwin, but I do believe it had to do with battery duration.

I very rarely use TB, and never hotplug it (though I do use the Mini DisplayPort), so I don't care (or even know) if hotplugging actually works for me.

After reading rembo10's comment, I made a research of "acpi_osi=!Darwin", and read a bunch of topics and discussions, in which they refer to "acpi_osi=Darwin". Besides, there is a news about "Thunderbolt hotplug support for Apple devices" in the LWN. You can access the story from "". I am just curious that is the difference between acpi_osi="!Darwin" and acpi_osi=Darwin. The second one already works like charm on my system. Thanks for your time.

I can also confirm this. Note that's it's acpi_osi="!Darwin" (@melmeiro ommited the "!").

I actually already had this kernel option because it greatly improves battery life, so all I had to do was actually remove the package.

Since I won't be using this anymore, I'll no longer be maitaining this package, feel free to adopt it.

After reading rembo10's comment, I have decided to give a shut to putting acpi_osi=Darwin in kernel options. It worked like a charm. I will no longer keep in using mba6x_bl driver on my Macbook Air (early-2014). Thanks a lot. You made my day.

Hey - not sure if this helps anyone but adding acpi_osi="!Darwin" to my kernel options, I no longer needed to use this package

@hobarrera I'm getting the same error as @dougv. I brought it up on pacaur's issue tracker, and here's what the author said [1]:

> Please follow proper VCS guidelines. If the issue still happens, open a new bug report.

Can you please take a look and see whether we're properly following the AUR guidelines for VCS packages?

hi. getting an error when installing with pacaur:

[CODE] mba6x_bl-dkms package(s) failed to install. Check .SRCINFO for mismatching data with PKGBUILD. [/CODE]

googling has not helped me fix this up. any tips?

thanks in advance

Sorry, looks like I'd never pushed my latest local changes. Current PKGUILD should work fine.
