OpenBSD is an alternative operating system to Linux and Mac OS X on the PowerPC platform. Save for Debian Sid, it is newer. It is by nature more secure due to its extremely extensive vetting and review of each line of code. It is inherently faster thanks to the lightweight kernel and lack of systemd. When compared to Linux, it has better compatibility with PowerPC machines. It has a far tidier and easier to understand file system than Linux. It is also the most well-documented system in the world (meaning there's a manual page for everything).

However, OpenBSD also has a smaller package library than Linux. It does not support FireWire or sleep mode on iBooks / PowerBooks, and its graphical environment (X Window Server) also does not support as many nVidia cards as Linux, so installed GPUs will likely be an ultimate deciding factor for most people, at least for desktop usage. For CLI use / server work however, OpenBSD remains an excellent choice for most all models.

As always, contributions to this Wiki are greatly welcomed and highly appreciated. Thank you.

Install Guide

The latest version is currently 6.7, released on May 19, 2020. Get it here.

1. Burn the image to a CD, and connect your Mac to Ethernet. Reboot, and hold 'C' at the chime (or Caps Lock light), then press 'Enter' when you get to the boot prompt. After the installer finishes booting, just follow the prompts. Most of the time, you'll be pressing 'Enter'. That said, the below instructions will serve as extra pointers.

2. Enter 'I' when you are greeted by the installer to start the installation process. When you are asked about xenodm, press 'Enter' to boot to a console (we'll enable it later). Then, enter your username when asked to set up a user.

3. Press 'Enter' when asked about the root disk. If you have multiple disks, 'wd0' = Disk 1 and 'wd1' = Disk 2, so in this case, answer according to which disk you wish to install on. Enter 'yes' when asked if you are sure you want the MBR partition table on your selected disk. This will delete all existing data and automatically partition the entire drive for OpenBSD, so be sure you want to do this.

4. Enter 'http' when asked the location of the sets, enter cdn.openbsd.org, when asked for the HTTP server, and hit 'Enter' when asked for the server directory (should be pub/OpenBSD/6.x/macppc). Press 'Enter' when asked for the set names (they should all be selected by default). Now, you must allow the system to install.

5. Press 'Enter' to reboot once you are congratulated on the installation success. Hold Opt at the chime to boot into the Boot Picker, then hit Ctrl + Z to switch into Open Firmware, then enter 'eject cd' to eject the disc.

Now that we're in Open Firmware, let's tell your Mac to automatically boot OpenBSD when first start up.

6. Enter 'setenv auto-boot? true'. Now, enter 'setenv boot-device hd:,ofwboot'. Afterward, enter 'shut-down' to save, then turn your Mac back on. OpenBSD will come up, then automatically configure itself for first-time use. This will take longer than usual, please be patient.

Congratulations! The system has been successfully installed!
Post Install Guide

1. Log in as your user account (username: <user>, pass: <your account password>).

2. Carefully review 'man help' and 'man afterboot'. Then, temporarily log in as root with 'su'. Enter your root password when asked.

3. Do 'pkg_add pico doas' to install the Pico text editor (similar to Nano, otherwise use vi) and doas, which is simpler than sudo.

4. Do 'pico /etc/doas.conf' and add the line 'permit persist <username>' to allow your account to perform administrative actions without logging in as root. Afterward, enter 'exit' to get out of the root account.

5. You are now ready to install a desktop environment. Once you have, do 'doas pico .xinitrc', and enter 'exec' followed by the name of the desktop environment / window manager you want xenodm to automatically start after login (ex. exec xfce4, exec i3, exec wmaker, etc.). Enter Ctrl + X, hit Y, and then hit Enter.

6. When you're ready to start xenodm, enter 'doas rcctl start xenodm', and 'doas rcctl enable xenodm' if you want it to automatically start upon boot.

Great initiative, many thanks for this thread. I've been wanting to try OpenBSD on my PPC Macs for quite some time (have already played with it on x86 and ARM) so this is an excellent "excuse" to do so and contribute to this wiki, if I can.

Some tidbits:

- Judging from my experience with MATE (it's GNOME 2 after all) I'd say it's too heavy for a G3.

- Installing the xfce metapackage will give you a basic setup; additionally installing xfce-extras will give you a more complete setup.

- I think the Lumina desktop environment (lumina) and the fluxbox window manager it uses are available as packages for OpenBSD so could be added to the OP after verification. It's a nice little DE/WM and works well on... constrained systems.

I had OpenBSD 6.1 working with GUI on an ibook (https://everymac.com/systems/apple/ibook/specs/ibook_g4_1.0_12.html) which is Mobility Radeon 9200. Knowing the OBSD approach I doubt the support has since been removed.

That’s interesting. Audio has worked OOTB for me on every PowerPC laptop I’ve tried OpenBSD on. Confirmed working on an IBook Dual USB 500 MHz, Dual USB 800 MHz, Dual USB 900 MHz, PowerBook G4 1.5 GHz, and PowerBook G4 1.67 GHz.

The B&W was my only test machine for this, so when it hung trying to connect to PulseAudio, I made the assumption.

Anyway, it's amended. False alarm. :)

The only reason I didn't designate MATE for a G4 is that it hasn't been tested yet on a G3 w/ OpenBSD. Thus, I'd prefer if it was first tested and confirmed too slow on a G3 before locking it to G4s.

What about xfce-goodies? Is extras the equivalent, or does it do something more than goodies?

Right, everything should be verified first. That's why there's a "?" after the KDE install command, because I didn't actually test it.

I'm actually no longer currently running OpenBSD, as I'm waiting for 6.6 to release in October before installing again on my B&W.

I'm on my phone at the moment, but I would make a few suggestions.

1. Use doas instead of su. Just add "permit persist username" to /etc/doas.conf and that's it.

2. On a laptop, get a Ralink or Atheros USB wireless adapter. The Broadcom based Airport card is worthless.

3. Fvwm and Cwm are in base. Cwm is my choice an all laptops.

4. Stick with pkg_add instead of adding additional package managers. It's simple and easier to use. "pkg_add -u" will update all installed packages. "pkg_info -Q package_name" will search for an available package called package_name and display it if available.

More when I get home

FYI a recent change in -current makes the Airport card (bwi) in my PowerBook run significantly better. This is the first time I have not needed to use a USB wireless adapter.

Just got a 667 MHz (maybe) Tibook and OpenBSD is smooth as silk on it. Full 2D/3D acceleration works on the Radeon 9000. Wifi works fine via the wi driver, though that card cannot handle WPA2 so I am using a Buffalo USB. Overall system performance is quite good and better in some ways than my much later 1.5 GHz 12”.

Interestingly, this was listed as a 1 GHz machine and the CPU reports itself as a 7455, but only at 667 MHz. From what I could find, the 7455 Tibooks were either 867 MHz or 1 GHz, and the 667 MHz models did not have a Radeon 9000 (which this definitely does). Tis a mystery to me.

The later (≥800MHz) TiBooks downclock to 667MHz and disable the L3 cache if run without a battery IIRC.

My battery is totally dead so this makes sense, thanks. Unfortunately new batteries are absurdly expensive so I will have to hunt for a used one

So the performance will even be better once a battery is installed.

OpenBSD is still on my try out list. I wanted to try it on my G5 quad but I think it would not use it to it's full potential because of lacking support for 64bit anyways

@556fmjoe why do you use OpenBSD over OSX or Linux even? Apart from security, is there anything it does more successfully?
Click to expand...

It's cleaner, simpler, much better documented, and more reliable. The code quality in particular is significantly better than what you'll find on Linux.

Here's the OpenBSD version of the "yes" utility: https://github.com/openbsd/src/blob/master/usr.bin/yes/yes.c

And here's GNU's implementation: https://github.com/coreutils/coreutils/blob/master/src/yes.c

Here's OpenBSD's echo.c: https://github.com/openbsd/src/blob/master/bin/echo/echo.c

And GNU's: https://github.com/coreutils/coreutils/blob/master/src/echo.c

The differences are pretty stark with the simplest C programs shown here, and they are even more apparent in complex code. Generally, OpenBSD will take the most simple, direct, and obvious approach whenever possible and that philosophy shows up in their code, documentation, and utilities. Connecting to the internet from the command line for example is a straightforward affair on OpenBSD. It's usually a much more complicated process on Linux and varies from one distro to the next.

I use Linux often (Gentoo at the moment), but I'm inevitably unhappy with it.

Does that translate to applications? Are browsers and media players more efficient that Linux/OSX?
Click to expand...

There's no built-in browser in base, though there is a set of audio tools included. 3rd party code is generally the same as on Linux; an inefficient, badly written program won't get any better on OpenBSD, though it will run with much better exploit mitigations. I do not notice much of a difference in performance.

Not strictly related to your question, but you may find the multimedia section of the FAQ interesting: https://www.openbsd.org/faq/faq13.html

And older, but still good paper on OpenBSD's sndio: https://www.openbsd.org/papers/asiabsdcon2010_sndio.pdf

Hi, I am attempting to follow these instructions, but when I get to the part where you enter "wheel..." it says that wheel is not found. None of the other steps following that work either, for example "pkg_add pkg_mgr" does not work, even if I run it as root.

I went down a rabbit hole with trying to change the installurl file, as suggested on another site, but that did not work either.

As a warning, I am a complete noob to this, so it is likely that there is something obvious I am missing. I got a iBook G4 with no OS and I have repeatedly failed to install any OS other than MorphOS so far.

Yes, it will say wheel is not found. But it will have worked if you are able to log in as root with 'su'. For instance, there is no 'sudo' OOB. You must log in as root with 'su', and then do pkg_add AS root (you will see a '#' instead of a '$').

Installurl should be left to default, so I can't help you there.

Linux / OpenBSD is primarily recommended for desktop machines. If you just want to use your iBook as an easy, reliable day-to-day notebook, installing OS X Tiger or Leopard is recommended. Just get an iso from Macintosh Garden, and burn it to disc.

Just add "permit persist username" to /etc/doas.conf, where "username" is your actual username. Then you can run "doas [command]" to run [command] as root, like you would with sudo.

What happens when you try to pkg_add something? Do you have an internet connection?

Since I've been tinkering with MintPPC and getting it running, would OpenBSD work on an Imac G5 ( being 64-bit and all )?
