Looks like I’m not the only one whose Intel iMac 27″ beautiful screen is discoloured and dirty, with dark patches, stripes and bands.

I think Steve’s video is worth transcribing because what he said certainly casts a shadow over Apple’s legendary customer service.

Hello everyone… Well, my name is Steven and I used to be a proud owner of an iMac 27″
A state of the art…. their flagship computer.
And basically after 90 days they invalidated my warranty and said that they’re not gonna fix it because it’s been used in a TOXIC ENVIRONMENT.
First of all, let me just take you on a journey… I’ll bring you over here…. to the environment that my iMac is used in.
Erm… let’s see, it’s almost like any normal person’s home office. maybe much smaller of course you know… but… well…

[Here he takes us on an impromptu tour of his humble, yet well kept, and might I say, well kitted… abode.
highlights include
microwave, plasma TV… iPhone and docking station…. and…. heaven forbid, he even has a Cup Noodle in to cupoard!!!!

It is during this tour that he shows us his iMac.


My iMac… My iMac… let me show you my iMac. I think you can see fairly well on the right hand side of the screen: Marks running from top to bottom. That’s actually… those seem to be getting worse. But even on a greyish background you can still see it fairly clearly. Bring it in….
Argh!… look at a that man! It’s disgusting!
But, erm… Apple have turned around an’ said I’ve been using the Mac in a TOXIC ENVIRONMENT.
YEAH. MY HOME OFFICE. YEAH. MY BLOODY HOME OFFICE!
Yeah, it might be attached to my kitchen…

[He continues the tour]


Look, my computer’s running absolutely bloody fine but…
The screen is a complete mess!
And Apple have said, “Go get stuffed, you’ve got a dirty house you’ve got a toxic bloody environment.”
And I will not accept that.
They want me to pay four hundred and seventeen frigging pounds for a new screen!
What? Because of this toxic environment? This toxic environment?
Jeezus! There’s millions upon millions of people around the world who have an office just like this…
Probably guys…. probably guys who have even small offices than this… Jeezus!

[Back on the tour]


Well. I’m afraid it’s over… You know like Apple… You know like…
Your firm… Steve Jobs….Your representative called my home a toxic environment!
And you need to get that sorted!
If you’re treating customers like this after 90 days… after 90 days… not even a year…
You are BREAKING THE LAW, sir… You are BREAKING THE LAW…
And you are breaking the covenant with he customer.
And I’ll not take…. I’ll not take it!

I sincerely hope they see their stupidity and you get your problem sorted out as rapidly as I did.

I think I’m going to send this to The Register. They always seem to know what to do with material like this!


Solution to the noisy fans on a Core 2 Duo Intel Mac Mini

As those who’ve been reading my blog may know, I started my conversion to the other side (Mac) on the 28th of Feb, 2005 with the purchase of a 1.42 GHz Mac Mini after gushing over my now wife’s 12″ Power Book.

I was taken by its size, it’s sleek lines, OS X and last but not least, its comparative silence next to my air moving PC.

I kept this machine for 3 years before handing it over to my brother in a vain attempt at getting him to move into the digital world (he is an artist of insane calibre, but with zero digital knowhow).

To replace it, I bought an Intel Mac Mini when the Core 2 Duo models were released.

Since then, I’ve been enjoying trouble free compting, but have had only one issue with my machine.

It’s an issue that started the moment I upgraded the RAM from its inital 1Gb to 2Gb and Continued after a further upgrade to 3 and then 4Gb.

That issue is a fan that revs up as soon as the system comes under even minor stress, drowning out the sound of my beige box Windows 3GHz P4 system with 4 hard disks!

I’m not talking about a fan that revs up and gets loud shortly after booting and stays loud constantly, I’m talking about a fan that revs up as soon as the system shows even a modicum of activity.

With the supplied 1Gb stick of RAM, this issue did not occur, but add a second stick and the fan goes berserk at any opportunity. The fan revs up so much that the CPU, GPU and HDD actually cool down below their respective idling temperatures!

Anyway, there is a Really Simple Solution (TM).

Step 1: Download and install SMC Fan Control.

Step 2: Open a terminal window

Step 3: type the following:

/Applications/smcFanControl.app/Contents/Resources/smc -k F0Mx -w 3e80

And your fan will become a much more sedate affair.

Why? Because this limits your fan to about 4000 RPM rather than the ear numbing 5500 RPM it is usually capable of.

A 20% or so reduction doesn’t sound much, but remember that fan noise often has sometimes a squared or cubed relation to rotational speed, and that ignores a system working at its mechanical limits, so even a minor reduction can give big gains!

Try it and see.

For the curious, the 4 digit number after the -w is:

HEX (Base 16) : Fan Speed x 4

If you set the speed too low, I recommend installing ANOTHER FAVE OF MINE, Temperature Monitor to keep an eye on your newly silenced computer, especially in summer.

My Cheapest iMac Yet

Just bought an iMac for our school. It’s a second hand but pristine G4 iMac 15″ 700MHz machine, just like the one I bought last February. It still even had the wrapping on the vertical tube supporting the screen and the little pair of ball speakers.

The shop assistant told me that it would run for about 30 minutes before shutting down. Curious, I asked if I could plug it in. He left me to it and I switched it on. Immediately, I saw the problem. The fan was rotating so slowly the blades were visible.

I’ll buy it! I said and walked home with a ¥3,980 (A shade over 20 quid) iMac.

Not wanting to open my currently working iMac again, I decided to check on line for the required fan replacement. A quick check of http://www5.plala.or.jp/kdreview/imac_g4_17.html showed the fan to be a 92mm x 25mm Superred part.  I remembered it from the one I opened last year, so even though it’s not the same machine, I bought it with confidence, along with an old 512mb PC133 stick of RAM.

I opened her up, replaced the fan and RAM,put her back together (a thirty minute job) and an hour after switching on later, the machine is still running.

Nice. I’ll have something to run iTunes on in our café section, now.

How to fix the ARD toolbar buttons/functions missing from Screen Sharing under OS X 10.5.5

September 18, 2008 1 comment

I’d like to thank a couple of my readers for telling me how to remedy the problem of the ARD Screen Sharing toolbar function hack that can no longer be applied once one upgrades to OS X 10.5.5.

The solution is glaringly obvious and I’m a bit annoyed I didn’t spot it myself.

Just use Time Machine and search for the Screen Sharing application, located in /System/Library/CoreServices/Screen Sharing.app and return to an older version of the app!

You gotta love Apple for handing you the solution on a plate.

Alternatively, dig out your Leopard DVD and pull it off there.

You’ll apparently get bugged by an upgrade screen.

I had read that Apple were trying to cut down on “Frankenbuilds” using software from different versions of the OS, but I guess this is still OK.

I’d like to try this, but since I have a nice, fully functional ARD 3.2 installed there’s not much point for me!

Still, I may try it one day. Let me know how you get on with these tips.
