Google yanks Apple Silicon Chrome port after browser is found to 'crash unexpectedly'

You'll have to run x64 version through the Rosetta emulation layer, or give it access to the Mac Bluetooth radio

Updated Google's attempt to launch its Arm port of Chrome for Apple Silicon Macs got off to a rocky start after it was forced to pull the browser over stability concerns.

"Earlier today we updated our Chrome download page to include a new version of Chrome optimized for new macOS devices featuring an Apple processor," Googler Craig wrote on the Chrome support pages. "We've discovered that the version of Chrome made available for download today may crash unexpectedly."

At the time of writing, the macOS ARM64 port of the browser remains unavailable. Folks now face two options: use the standard x86_64 version, which will run happily on their Arm Mac via the Rosetta 2 emulation layer, or if they managed to download the Apple Silicon port, use a workaround that involves giving Chrome access to the Mac's Bluetooth radio.

The emulated version shouldn't prove unbearably slow. Benchmarks of Apple's latest in binary translation tech shows Rosetta2 is roughly 20 per cent slower than the native equivalents. Given this is a fairly brisk chip to begin with, performance is roughly comparable to what you'd get with a well-specced last-generation Mac.

Still, this episode is more than a touch embarrassing for Google, particularly given the pains made by Apple to ease the switch to Apple Silicon. These included a nearly six-months head start, as well as access to Arm-powered Developer Transition Kit machines, to iron out any kinks.

Released earlier this week, Chrome 87 comes with several performance enhancements, as well as changes designed to improve user security. Included is a fix for the NAT Slipstream attack identified last month by hacker Samy Kamkar, plus new tab prioritisation tech, which Google claims will reduce CPU utilisation by up to five times, reduce RAM usage, and extend battery life by up to 1.25 hours.

We've asked Google when it will re-upload the Apple Silicon port of Chrome, and will update this post should we hear back. ®

Google has now emitted what it says is a fixed build of the Apple Arm port of Chrome.

    In-brief Governments around the world should pass intellectual property laws that grant rights to AI systems, two academics at the University of New South Wales in Australia argued.

    Alexandra George, and Toby Walsh, professors of law and AI, respectively, believe failing to recognize machines as inventors could have long-lasting impacts on economies and societies. 

    "If courts and governments decide that AI-made inventions cannot be patented, the implications could be huge," they wrote in a comment article published in Nature. "Funders and businesses would be less incentivized to pursue useful research using AI inventors when a return on their investment could be limited. Society could miss out on the development of worthwhile and life-saving inventions."

    More papers describing the orders and messages the US President can issue in the event of apocalyptic crises, such as a devastating nuclear attack, have been declassified and released for all to see.

    These government files are part of a larger collection of records that discuss the nature, reach, and use of secret Presidential Emergency Action Documents: these are executive orders, announcements, and statements to Congress that are all ready to sign and send out as soon as a doomsday scenario occurs. PEADs are supposed to give America's commander-in-chief immediate extraordinary powers to overcome extraordinary events.

    PEADs have never been declassified or revealed before. They remain hush-hush, and their exact details are not publicly known.

  • Stolen university credentials up for sale by Russian crooks, FBI warns
    Forget dark-web souks, thousands of these are already being traded on public bazaars

    Russian crooks are selling network credentials and virtual private network access for a "multitude" of US universities and colleges on criminal marketplaces, according to the FBI.

    According to a warning issued on Thursday, these stolen credentials sell for thousands of dollars on both dark web and public internet forums, and could lead to subsequent cyberattacks against individual employees or the schools themselves.

    "The exposure of usernames and passwords can lead to brute force credential stuffing computer network attacks, whereby attackers attempt logins across various internet sites or exploit them for subsequent cyber attacks as criminal actors take advantage of users recycling the same credentials across multiple accounts, internet sites, and services," the Feds' alert [PDF] said.
