Thanks for that.  8^)

But what I am interested in is knowing if / how the OP actually solved the issue.
Or not and what steps he took while attempting to do it.
All useful information for the forum.

ie: towards getting Devuan installed on a Mac.

Best,

A.

that might be useful

Did you get your Mac / ACPI issue worked out?

Whatever data you have been able to gather will be useful to others.

Best,

A.

Yes.

Every time I see someone wanting to run Linux on a Mac[whatever] I try to pitch in.
To me, it's personal and after all, hardware is just hardware but the BIOS has to be able to access it.

But thanks to crappy BIOS / DSDTs encouraged by the usual suspects, many notebooks/netbooks/laptops of various brands / CPUs have needed tweaking. Apple hardware is a prime example.

@deviate
Try adding this stanza to the kernel command line: ACPI_OSI=Darwin 
See here: https://wiki.archlinux.org/title/MacBookPro11,x

Just in case, test this first by editing the grub configuration at boot so that the edit will not be permanent.
ie. it will apply to only that boot.

If it boots properly, carefully check the dmesg printout to see what is going on.
Save it to a *.txt file and compare the printout with / without the edit.

There may be useful data there.

Best,

A.

was wrong laying blame prematurely,

this is great info, resurfced!

there was however special needed for keyboard layout to get "tilde" "email-key" etc on mac keyboard etc. if am not mistaken, could have been covered elsewhere, and depends naturally also on the specific keyboard layout being used.

Maybe this page could sort the OP out?

Have a look at the Single-Boot: Ubuntu Only bit.

Best,

A.

it is dualboot macos x / lubuntu , but was difficult to setup; would not have succeeded without a proper guide and a few tweaks that were offered i think as an ubuntu help page (espcially also for keyboard layout).

unfortunately ubuntu website has "received" a major overhault and cannot find the help page any longer since it could have had contained valuable information even when compared to a newer macbook5,2.

but i think with the newer macbook you will have much less issues and with devuan maybe less so so good luck for the usage.

Hit the MacBook forums

Sorry if this is a dumb question, but you mean the ones on discussions.apple.com, right? I've never cared about MacBook stuff until a few months ago when I picked this one up so I'm not really familiar with the relevant forums.

So I assume I will have to just reconfigure and build the kernel?

No idea. Hit the MacBook forums...to determine that this is a MacBook ACPI Kernel specific issue.
If it is and you are lucky and someone has posted which driver module you need..just add it to your default Debian kernel config and re-compile.

Been bit by this before on an Intel (not mac) laptop, the kernel did not have the correct ACPI motherboard support.

So I assume I will have to just reconfigure and build the kernel? Guess I can do that when I'm at my other machines, doing this on a Core 2 Duo sounds a bit painful.

rebuild your kernel

I don't know what you need, but -support and -support-base are probably good ones to try first.

I wasn't aware anything else might be needed
