airport extreme update 2008-001

apparently, the new airport extreme update 2008-001 (http://www.apple.com/support/downloads/airportextremeupdate2008001fortiger.html) puts an extra load on the cpu, at least on my system – intel macbook pro running 10.4.11.

patches that were already at the edge of the cpu consumption might start cracking.

disabling the airport solves the problem; one shouldn’t chat or surf the net while running maxmsp anyways :-)

this one took two days to figure out…

this is very interesting and worth investigating further

but for those of us not using Airport Extreme and still on OS X 10.4.x
I wonder if the new(er) versions of Quicktime might also be a culprit
in the recent experience of audio breakup/glitching when playing
mp3′s and doing anything network related (i.e. chat, web, ftp, email
etc)

anyone else experience this?

my config:

OS X 10.4.11
G4 PB 1.67GHz
=========
Max/MSP 4.6.3
Jitter 1.6.3
Pluggo 3.6.1
Soundflower 1.2

I’ve been getting some more crackling than usual lately. I thought it was my inefficient patching, but the CPU loads are way under 80% (even around 30%) on a patch i’ve been working on. I haven’t listened through any external audio, just the built in Macbook Pro audio. increasing the audio buffers helps, but not all the time.

10.4.11 macbook pro
all latest updates (probably why)

yeah sorry for not being more clear
but the audio buffer break-up happens in apps other than Max/MSP as well
Peak, iTunes, VLC (the worst), and Quicktime Player all crackle/
glitch when I have either several audio apps open (not playing)
or I’m playing audio while chatting or doing something online
and this is a recent development
something I’ve noticed in the last couple of months or so
and typically can be cured by shutting down Adium/Firefox and/or
extra audio apps running
so I’m guessing that a recent OS update might have some CoreAudio
‘fixes’ that might be causing this?

i experienced this myself, but found out, that replacing the updated airport-update with a previous version (http://www.apple.com/support/downloads/airportextremeupdate2007004.html)fixed this.
at least for the airport-related troubles. though i haven’t experienced your problem, kim.

thanx for sharing Donk
i was experiencing the same crakcles and gliches on mabook with
10.4.11 and when i turned airport off all problems seem to be stopped

maybe with leopard will be all fine?

I also have cpu peaks and bad sound crackles since I installed last
airport extreme update…
This is hapenning with any audio app, alone or not, as soon as airport
is on (even without any web app running) on a macbookpro, 10.4.11, 4.6.3.

Yep, bad things were happening for me audiowise after recent update. It was definitely tied in with airport as glitches went away if I turned off my airport.

I re-installed the previous update at the link hidden elsewhere on this page and all is well again…

MBP 2.2 running 10.4.11…

FWIW, I restored 2007-004. Seems to clear up things.

Slightly off topic, but has anyone installed the Leopard Time Machine and Airport Update 1.0? I’ve got a whole queue of updates waiting for me to try out after I finish up some projects but I have grown extra suspicious of this update hearing that some have had problems with a recent Tiger airport update.

roth,
we’re not running Leopard out here… not unless Andrew tells us that we can :-)

gusanomaxlist,
unfortunately this is only a temporary solution, to get the work done. Eventually, we have to update/upgrade the machines to keep up with the technology. Otherwise, I will still be happily running my old Atari 1040ST.

true, but I am in the middle of some work using wireless networking between computers (it’s incredibly cool) so I don’t feel like waiting months until Apple releases another update. Technology will have to wait…

you know some people still do ;)

I am trying to install the download from
http://www.apple.com/support/downloads/airportextremeupdate2007004.html but all of my disks are marked with prohibitions. Is there something about the airport driver I should delete first?

in the apple thread mentioned before there’s an explanation about using Pacifist to remove / replace system files related to the bad airport behavior, using the older update, check it out:

Hello fellow maxers.

Reviving this old thread – I got some questions for you guys.

Like others, I too had issues with the 2008-001 airport update. So I went back to the older version using pacifist and have avoided this particular update since.
Now, there is a security update available for my machine/os (2008-006) and I expect it to include an airport update (since this particular airport update is not offered separately anymore). Has anyone run this update without running into the same airport issues? I have max 5 by now, but only for playing around. for work and performance i still rely on 4 and will probably continue to do so for considerable time more, so this is more than academic for me.

Is the airport issue fixed? Or would i have to go back in using pacifist to “downgrade” the airport part of this security update?

Any thoughts appreciated.

Regards,
Klaas-Jan Govaart

PS: 10.4.11, MBP, 4.6.3

OK, rephrasing my question…

I’m planning to do a full reinstall of OS X 10.4.11 on a MBP.
After applying all the updates using “Software Update”, do I still have to hack in the old airport component or will the newer one work ok with Max 4.6.3?

Thank you,
kjg

I also held off running this update until recently, when I noticed that it
now claims to address various issues relating to audio apps, which I take to
means the issue is sorted – and indeed, it appears to be so,
Cheers

thank you for your reply Roger.

where did you read this? is there some apple website that documents the updates in more detail?
