The Computer Hardware Understanding Developer Tools (CHUD Tools) are designed to help hardware and software developers measure and optimize the performance of Macintosh systems running their products under Mac OS X. All of the CHUD tools fully support the latest in Macintosh hardware and software.

What's New

Version 4.6.1:

fixes a variety of bugs and adds support for new hardware.
Significant changes include:
Improved support for iPhone profiling

Requirements
PPC / Intel, Mac OS X 10.4 or later. ADC Membership (to login for download), which is free at its basic level. Join here.

Please note this page, it should be of special interest to all developers. It demonstrates how to use 'Shark', one of the CHUD tools which can dramatically increase your app's performance. When a developer employs what Apple calls "opportunistic optimization", Shark delivers a big payoff with a little effort. It's the right thing to do.

Be the first to recommend a similar software title.

You have to login to ADC and goto developer tools for the current version of CHUD.

Actually in Tiger the stability problems pretty much disappeared. I have nap enabled all the time on my MDD Dual 1GHz and have not had a problem in over a year of heavy ProTools/Digital Performer, Final Cut Pro, Photoshop, or WoW use.

I have the exact same machine. Which version of CHUD are you using?

MacUpdate Lon commented on 09 Oct 2007

Dale, you do realize that the parent post was posted almost a year and a half ago? And at that time the current version of CHUD was 4.3.3.

The date of the post and the version number which was current at the time of the post is stamped onto the end of the post, as is the case with any and all posts in the reviews section at MacUpdate.

Yea! The Processor Palette (accessible from the Processor menuextra) doesn't throw an exception now!

Right on Apple!

I have a Dual 1.25GHz mirrored door PowerMac G4. Under Panther, I could use the CHUD tools to put the processor in a nap mode, which kept the processor running substantially cooler. With Tiger, the CHUD tool won't allow me to select "Allow Nap"

Use the 3.x version of CHUD to still be able to enable Nap Mode. I use it on my Dual 1.25 G4 with no problems. If you haven't, create an applescript to enable it on boot.

I can confirm this. Downgrading to 3.5.2 put back the 'allow nap' option. Get it at ftp://ftp.apple.com/developer/Tool_Chest/Testing_-_Debugging/Performance_tools/

I would not recommend this as putting the G4 in nap mode was eliminated because it caused system-wide freezes and kernel panicks.

A safer option is to edit Apple's CPU fan kernel extension's Property List fan table to speed up to higher RPMs at lower temperaturesâ€” CHUD tools or not I never run above 119Â°F with my settings.

Here's more info (it's a Google-cached page since the original doesn't seem to be up anymore):

BTW- I've a MDD G4 as well and this works perfectly...

Does anyone know if this version, 4.0.2, allows you to turn NAP on and off in Hardware prefs? Turning off NAP seems to be the only fix for a squeeling PSU in G5's.

I can't say re: 4.0.2 - I'm still downloading the installer - but 4.0.1's "Processor" pref pane has a Nap checkbox for on & off switching here. (My Mac is the May '03 1 GHz G4 eMac Combo model, in case that makes any difference...?)

Yes, The NAP on/off switch is still there!

Anonymous commented on 08 Mar 2005

ummm does no one use this for its intended purpose/?

Anonymous commented on 08 Mar 2005

sure, but asking about nap is kinda relevant as Nap wouldn't stick in the last release. Of course people do use it for things it wasn't intended for because it's useful. So I'll ask. Does nap stick in the prefs now on restarts or do I have to keep checking?

Anonymous commented on 09 Mar 2005

perhaps it doesn't stick because it's not meant to stick, because CHUD's intended purpose is performance testing of software, not altering your hardware parameters.

Anonymous commented on 28 Jun 2005

If Apple helped us keep our processors from overheating there would be no need to use it for anything else.

If Apple managed to make chirp-free PSUs, there's be no point in using it other than its intended purpose.

The CHUD tools are great, especially Shark. Just open Shark up, start some executable, and tell Shark to start sampling. You instantly find out what are the hot loops, load/store problems, etc.

One minor warning about the update: If previously you double-clicked on a source-code line number in the profile view to see Shark's annotations to your source, you'll be disappointed. This feature isn't working in Shark 4.

After installing CHUD 4.0b6 on my G4 OS 10.3.5, the G4 was unable to boot! I disovered that the next day and my automatic back up app had already cloned the main drive on the back up drive. The back up drive was unable to boot too.
I had to reinstall the OS from DVD, update it, etc.
A nightmare.
I reinstalled CHUD on the back up drive just to verify -> unable to boot again.
Thanks CHUD.

Of course, being the well trained developer that you are, you knew better than to install a beta, that is what the b stands for in the version number, on your primary patition. Right? Didn't think so.

Anonymous commented on 11 Apr 2005

Of course not. I also run the Tiger beta and call Apple support constantly to complain about whats not ready yet.

Anonymous commented on 11 Apr 2005

Oh, please.

I've had CHUD tools installed since who knows when. No problems here. (G3 iBook, OS X 10.3.8 currently)

Proper and preventive maintenance, anyone?

Huhhuhh, Huhhhih, I've got CHUD.

You disable nap, in the System Prefs, at the bottom where the new module is loaded, after you install CHUD.

Personally, I've got a Dual 1.8 and it does NOT have the noise problem. Is it possible Apple did a quite revision? Or am I just lucky?
