Apple in another dust-up with its fans: iMacs, MacBooks lack filters, choke on grime – lawsuit

Pay dirt: Owners of knackered kit drag iGiant into court

Apple was sued in the US this week over claims that design flaws in its iMac desktop and MacBook laptop computers allow dust into the machines, causing the screens, fans, and circuitry to fail.

The complaint, filed Wednesday in San Jose, California, on behalf of plaintiffs Kim Ahern of Arizona, Nikolas Frenzel of Colorado, and Justin Evans of Wisconsin, suggests Apple's marketing claims that its products are rigorously tested are misleading. It also argues the company is overcharging non-warranty customers for repairs.

The district court filing contends that Apple's omission of dust filters in its iMacs and MacBooks has led to repeated product failures, in the form of smudged screens and fan malfunctions that result in overheating and processor crashes.

"The components in Apple’s computers generate a great deal of heat during use, and Apple installed fans and vents to cool them down," the complaint explains. "But Apple did not install any filters for the vents. As a result of this filter defect, the fans suck in dirt and debris that get stuck behind the screen, causing a permanent dark smudging to appear in the corners of the screens."

Beyond degrading screen appearance and clarity, the presence of dust in these machines can damage the fan that maintains a safe temperature for the motherboard, the lawsuit contends. Once the fan stop working, the CPU may overheat and cause the machine to crash.

"Apple knew that not installing filters on the computers would have negative consequences for computer owners, but decided not to install them, either for aesthetic or monetary reasons," the lawsuit paperwork states. "On Apple’s own website, computer owners have been complaining about the dark, smudgy marks on their displays for years, which often appeared just after their one-year warranty expired."

Apple MacBook butterfly keyboards 'defective', 'prone to fail' – lawsuit


Customer complaints about smudged screens can be found in Apple support forums and in blog posts.

Dust has proven to be particularly problematic for Apple products in recent years. Earlier this year, the Cupertino idiot tax operation was sued over keyboard design changes that affected MacBook models starting in 2015 and MacBook Pro models starting in 2016. The issue, it was claimed, was that dust interfered with Apple's low-profile "butterfly" keyboard design.

Apple this year added a rubber separator inside its laptop keyboards to address the problem.

With regard to iMacs, Apple is said to charge about $600 for a smudge fix that involves replacing the screen. But the legal filing argues the Silicon Valley giant has failed to inform customers that iMac screens, held in place with magnets, can be removed to clear trapped dust without much effort or expense.

"Apple could simply use suction cups to remove the glass panel on many of them, and use a vacuum or a cloth to clean the screen," the complaint states. "Instead, Apple tells customers that they must replace the entire screen, at a cost exceeding $600, apparently in order to increase Apple’s profits at the expense of the customer."

The lawsuit alleges that Apple violated California laws governing unfair competition, false advertising, breach of contract, disclosure obligations and consumer protection. It seeks recognition as a class action, on behalf of other customers believed to be affected.

    Microsoft has whipped the covers off yet another take on code-in-the-browser with a lightweight version of Visual Studio Code, while unveiling the version 1.0 release of support for Red Hat Java in the freebie source wrangler.

    It comes after last month's preview of the code editor that runs entirely in the browser, and will doubtless have some users pondering the difference between this and Microsoft-owned GitHub's, which also pops a development environment into the browser. One of the biggest of those differences is a lack of compulsory integration with the VS source-shack; this is unavoidable with (the clue is, after all, in the URL.), on the other hand, will permit the opening up of a file from a local device (if the browser allows it and supports the File System Access API) in what looks for all the world like an instance of Visual Studio Code, except surrounded by the gubbins of a browser.

  • No swearing or off-brand comments: AWS touts auto-moderation messaging API

    Automate everything – but while human moderation is hard, robot moderation tends not to work

    AWS has introduced channel flows to its Chime messaging and videoconferencing API, the idea being to enable automatic moderation of profanity or content that "does not fit" the corporate brand.

    Although Amazon Chime has a relatively small market share in the crowded videoconferencing market, the Chime SDK is convenient for developers building applications that include videoconferencing or messaging, competing with SDKs and services from the likes of Twilio or Microsoft's Azure Communication Services. In other words, this is aimed mainly at corporate developers building applications or websites that include real-time messaging, audio or videoconferencing.

    The new feature is for real-time text chat rather than video and is called messaging channel flows. It enables developers to create code that intercepts and processes messaging before they are delivered. The assumption is that this processing code will run on AWS Lambda, its serverless platform.

  • UK government puts £5bn on the table in trawl for public sector networks services

    I dream of wires, say Whitehall’s big buyers

    The UK's central government procurement agency is chumming the waters around the market's swimmers, hoping to tempt suppliers into providing a range of computer network services and kit with a £5bn tender.

    The buying spree, which will officially begin when a framework agreement starts in fiscal 2023, involves a large spread of hardware, software and services around IT networks. Included are categories such as networking, internet and intranet software packages, network interfaces, network operating system software development services and so on.

    Crown Commercial Service, the cross-government buying organisation that sits within the Cabinet Office, has launched what is known as a "prior information notice" to start talking to suppliers before it forms the official competition to be on the framework: a group of contracted suppliers from which a huge number of public sector bodies can buy.
