NetBSD 5.0.1 on Mac Mini G4 (PPC) Permalink

NetBSD, OSX Added less than a year ago and last edited less than a year ago

Here are my notes from installation. I used these resources: NetBSD on a Mac Mini, Notes from installing on a G4 Mac Mini and the INSTALL.html from the ISO.

I will clean these up shortly (hopefully.)

Use the OSX CD to boot the OSX installation program on your Mac Mini hold down C while booting)
Use Disk Utility to create two partitions: HFS named Boot; UFS named BSD
quit Disk Utility
On other computer, copy ofwboot.xcf and netbsd kernels (netbsd-GENERIC.gz) to USB stick
Insert USB stick in Mac Mini
Open Terminal
In shell:
1. cp ofwboot.xcf and netbsd kernels to /Volumes/Boot
Quit Terminal
Reboot Mac Mini
Start up to openfirmware
Eject OSX CD
Insert NetBSD installation CD in Mac Mini
In Open Firmware:
1. boot cd:,ofwboot.xcf netbsd.macppc
Start in shell (not install)
In shell:
1. pdisk /dev/wd0c
  1. leave apple partition map
  2. leave hfs 'boot'
  3. delete ufs 'netbsd'
  4. create new partition as / type (a)
  5. create new partition as swap type (b)
  6. write, exit
In shell:
1. newfs /dev/rwd0a (yes, note the r)
2. mount /dev/wd0a /mnt
3. cd /mnt/
4. mkdir etc
5. cat > etc/fstab
  - /dev/wd0a / ffs rw 1 1
  - /dev/wd0b none swap sw 0 0
  - ^D
6. cd /
7. umount /mnt
8. sysinstall
Select 're-install sets...' from sysinstall menu
Reboot Mac Mini
In Open Firmware:
1. boot hd:,ofwboot.xcf netbsd-GENERIC.gz
In shell: passwd adduser -m you passwd you
Reboot
In Open Firmware:
1. setenv auto-boot? false
2. setenv boot-device hd:,ofwboot.xcf
3. setenv boot-file netbsd-GENERIC.gz
4. reset-all
Now when you start your mac mini you will always go to openfirmware - just type 'boot' to start

Try Chrome for Mac Permalink

Cool, OSX Added less than a year ago

Get the developer release here.

I'm finding it pretty good... it imported all my ff keywords and it uses them correctly, and it has the same 'search anywhere' in the URL/title that ff does.

pkgsrc on OS X Permalink

OSX, Shell, NetBSD Added less than a year ago

I've tried fink and macports but found both of them very broken at some stages. They have quite recent ports in them though which is good... but not good enough when you look at how frequently they fell over.

It turns out the NetBSD port tree (pkgsrc) can be used on Mac OS X!

This page describes the process you need to install it.

Very nice!

VMWare Fusion Headless Mode Permalink

VMWare (Fusion), OSX Added less than a year ago

Read here about setting up VMWare Fusion in headless mode. In Terminal.app do this:

$ defaults write com.vmware.fusion fluxCapacitor -bool YES

Then restart VMWare Fusion. When your VM comes back up go to the View menu and select Headless mode.

MacPorts Corruption Permalink

OSX Added less than a year ago

If you have quit macports half-way through an installation (by closing the terminal window accidentally, or whatever,) you may have a corrupt port that is partially built/installed. You can clean the port fully and start again with:

sudo port clean --all db46

... where db46 is the corrupted port. Thanks go to blas.phemo.us

Forwarding X Permalink

X, NetBSD, OSX Added more than a year ago and last edited more than a year ago

My host is Mac OS X, and my guest is a NetBSD VM running on the host. This will show you how I forward X apps from guest to the host.

Ensure host has X11

On Mac OS X you can install X11 from the OS install disk that came with your computer.

Start X11 on host

On Mac OS X, start /Applications/X11.app

Get display list on host

In the xterm that was opened up on Mac:

host$ xauth list
YourBox.local/unix:0  MIT-MAGIC-COOKIE-1  dfa82d25b775957b7571f76727e51f3c
10.1.1.2:0  MIT-MAGIC-COOKIE-1  dfa82d25b775957b7571f76727e51f3c

We are interested in the one that does not have "unix" in it, i.e. the second line. Copy this line, we will be using it below. (The above is an example, yours will look different.)

Ensure guest has X11Forwarding enabled

guest$ grep X11Forwarding /etc/ssh/sshd_config 
X11Forwarding yes

... change if it's not enabled, and remember to restart sshd.

SSH to guest

host$ ssh -X guest

... the X flag enables X11Forwarding over this ssh connection.

Export display

guest$ export DISPLAY=10.1.1.2:0  # use the IP:Number combination that you got from xauth list
guest$ xauth add 10.1.1.2:0  MIT-MAGIC-COOKIE-1  dfa82d25b775957b7571f76727e51f3c

Run an X App

guest$ xlogo

... and watch it appear on your host.

iTunes vs. SongBird (Resource Battle) Permalink

OSX Added more than a year ago

Here are four grabs from top, with both apps not playing anything, just sitting around:

  PID COMMAND      %CPU   TIME   #TH #PRTS #MREGS RPRVT  RSHRD  RSIZE  VSIZE
 2963 songbird     4.4%  0:15.06  19   202  1044  52.2M+ 55.6M+ 83.6M   722M

 2951 iTunes       0.0%  0:02.86  12   223   353  21.8M  36.6M  40.8M   461M

 2993 songbird     1.5%  0:04.39  18   141   774  42.5M+ 49.7M  69.5M+  655M+

 2995 iTunes       0.0%  0:02.19  12   223   352  21.7M  37.6M  40.8M   461M

What do those headings mean?

CPU Percentage of processor time consumed (kernel and user)
TH Number of threads
RPRVT Resident private memory size
RSHRD Resident shared memory size
RSIZE Total resident memory size, including shared pages
VSIZE Total address space allocated, including shared pages

So SongBird uses a bit more memory than iTunes and seems to be doing some processing even when there is nothing being played.

When I play the exact same song on both (at the same time) this is what happens (four grabs again):

  PID COMMAND      %CPU   TIME   #TH #PRTS #MREGS RPRVT  RSHRD  RSIZE  VSIZE
 2995 iTunes      14.7%  0:04.53  15   231   367  23.3M  37.3M  42.8M+  465M 
 2993 songbird    13.3%  0:13.33  19   185   893  46.0M  52.0M  75.4M+  668M+

 2995 iTunes       5.1%  0:06.97  15   231   367  23.3M  37.4M  42.8M   465M 
 2993 songbird    13.8%  0:18.66  18   184   890  44.5M  52.1M  73.7M-  666M-

 2995 iTunes       5.0%  0:08.27  15   231   367  23.3M  37.6M  42.8M   465M 
 2993 songbird    14.3%  0:21.41  18   184   900  45.1M+ 52.3M  74.3M+  667M+

 2995 iTunes       5.1%  0:09.44  15   231   367  23.3M  37.7M  42.8M   465M 
 2993 songbird    13.2%  0:23.84  18   184   910  45.7M+ 52.4M  74.9M+  667M+

So SongBird is the bigger hog, I think.

P.S.: The test song was Girl U Want - Devo

NetBSD VM Permalink

NetBSD, OSX, X Added more than a year ago

... and the new NetBSD VM is working. pkgsrc is the packages system for NetBSD. If you are looking for mod_perl it is in www/ap2-perl. pkgsrc has a cool feature with sysutils/open-vm-tools being their port of VMWare tools. So you can just:

# cd /usr/pkgsrc/sysutils/open-vm-tools
# make && make install

... instead of installing the VMWare tools normally by mounting the fake CD image. NetBSD isn't officially supported by VMWare anyway, though they reckon the normal tools will work if you pretend it is a FreeBSD system and have FreeBSD emulation on.

Here is an XF86Config that I stole from somewhere (see the comments section, thanks guy.) It works great for the MacBook:
