A new flaw has been discovered in macOS High Sierra that can cause data to be lost when writing to disk images. It affects those formatted using the Apple File System (APFS) specifically, but it shouldn’t be a problem for your primary SSD. Apple’s latest software releases have been plagued by pesky bugs. The company has worked […]
Apple’s APFS file system included in macOS High Sierra suffers from a disk image vulnerability that in certain circumstances can lead to data loss, according to the creator of Carbon Copy Cloner.
In a blog post last Thursday, software developer Mike Bombich explained that he had uncovered the data writing flaw in the Apple File System, or APFS, through his regular work with “sparse” disk images.
For those who aren’t familiar with the term, a sparse disk image is basically a file that macOS mounts on the desktop and treats as if it was a physically attached drive with a classic disk volume structure. The flexibility of sparse disk images means they are commonly used in the course of performing backup and disk cloning operations, hence Bombich’s extensive experience with them.
Earlier this week I noticed that an APFS-formatted sparsebundle disk image volume showed ample free space, despite that the underlying disk was completely full. Curious, I copied a video file to the disk image volume to see what would happen. The whole file copied without error! I opened the file, verified that the video played back start to finish, checksummed the file – as far as I could tell, the file was intact and whole on the disk image. When I unmounted and remounted the disk image, however, the video was corrupted. If you’ve ever lost data, you know the kick-in-the-gut feeling that would have ensued. Thankfully, I was just running some tests and the file that disappeared was just test data.
Two related problems are identified by Bombich, above. The first is that the free space on the APFS-formatted sparse disk image doesn’t update as it should when the free space on the underlying physical host disk is reduced. The second problem is the lack of error reports when write requests fail to dynamically grow the disk image, resulting in data being “written” into a void. Bombich tracks both bugs back to macOS’s background “diskimages-helper” application service, which he has since reported to Apple.
Every installation of High Sierra converts the existing file system to APFS, which is optimized for modern storage systems like solid-state drives. However, as Bombich notes, ordinary APFS volumes like SSD startup disks are not affected by the problem described above, so the vast majority of users won’t be affected by it – the flaw is most applicable when making backups to network volumes. Bombich says Carbon Copy Cloner will not support AFPS-formatted sparse disk images until Apple resolves the issue.
The APFS flaw follows the discovery of another bug in Apple’s operating systems that received extensive coverage last week. That bug is induced by sending a specific character in the Indian language Telugu, which causes certain apps on iPhones, iPads, and Macs to freeze up and become unresponsive. The Telugu character bug has already been fixed in Apple’s upcoming iOS 11.3 and macOS 10.13.4 software updates.

Alphabet reported today in its annual earnings call that the company’s fiscal Q4 was a bit of a dismal one, owing to a decision to provision a new tax on foreign assets ahead into the 2017 fiscal year. Basically, Google took a $ 9.9 billion tax hit in the last quarter of 2017, dramatically lowering the effective net income the company earned for the whole of the fiscal year.
Google lost $ 3 billion in Q4, but for 2017 overall, it managed net income of $ 12.7 billion on revenues of $ 110.8 billion.

CRISPR Treatment Slowed Down Deafness
Almost half of all deafness cases are caused by genetic factors, but treating inherited hearing loss is tricky. Now, scientists have shown they can stop a type of progressive hearing loss – caused by a genetic mutation – using the CRISPR-Cas9 gene editing tool. A team led by David Liu at Harvard University injected a CRISPR protein capable of targeting a genetic mutation responsible for a type of deafness into live mice’s ears. The mice used in the study, published in Nature, had a mutated copy of the Tmc1 gene, which causes eventual deafness, alongside one normal copy of the gene. The one-time CRISPR treatment slowed down deafness in the mice.
The mutant Tmc1 gene is dominant, so the presence of just one copy will lead to progressive hearing loss in humans and mice alike. The mutation kills off the ear’s hair cells, which detect sound, over time. Mice with one mutant Tmc1 copy have substantial hearing loss after four weeks, and are essentially deaf after eight weeks – in humans, this progression often starts in childhood and could last decades.
But when the CRISPR-Cas9 editing tool was injected into a mouse’s ear, it displayed superior hair cell health and survival than in the same mouse’s other ear, which did not receive the same injection.
The mice with the mutated gene that received treatment still responded to loud noises at eight weeks, whereas the mice that didn’t receive the treatment had no startle response. “We were really excited when we observed hearing preservation in the injected ears but not the uninjected ears of the same mouse,” reflected Liu, in comments shared with Futurism via email. “Especially since we were not sure at that point how well the promising editing results we observed in cultured cells in a dish would translate into live animals.”
The mutated copy of Tmc1 differs from its normal counterpart by only a single DNA letter. Still, Liu and his team were able to disrupt the former while leaving the latter unchanged thanks to the CRISPR Cas-9 tool, which Liu described as a “pleasant surprise.”
Furthermore, while only a small amount of the target cells were actually repaired – 10 to 25 percent – researchers observed an improvement to the health of the mice’s hair cells. The team also observed a marked improvement in the treated mice’s hearing. At four weeks, treated mice could hear sounds that were 15 decibels quieter than their untreated counterparts. While there are still challenges to overcome, these successes bode well for the treatment.
Moving forward, delivery methods, improved efficacy, and an investigation into potential side effects are top priorities. Liu hopes to perform further tests on larger animal models, as well as further research into the possibility of using the same technique to address other diseases with a genetic component.
These steps are crucial if we’re to find out whether the procedure could give medical professionals a way to restore their patients’ hearing. “There’s still quite a bit of work to do before this approach might be used in humans,” Liu said.

Far from just being bad news for polar bears or vulnerable island chains, melting Arctic sea ice caps can affect areas a long way from the Arctic region, bringing not only higher sea levels, but also severe drought. This may be the case for California, which could see its already extreme lack of water getting worse in the coming decades, according to researchers at the Lawrence Livermore National Laboratory.
In a study published today in Nature Communications, climatologist Ivana Cvijanovic and her team found that shrinking glaciers in the Arctic can modify atmospheric temperatures over the tropical Pacific. In turn, this heat imbalance can push rain-rich clouds away from California towards Alaska and Canada.
“On average, when considering the 20-year mean, we find a 10-15 percent decrease in California’s rainfall. However, some individual years could become much drier, and others wetter,” Cvijanovic said in a press release.
The unprecedented drought that hit the region between 2012 and 2016 was attributed to a Pacific high pressure system known as the Ridiculously Resilient Ridge. “It’s the main reason we’re in a drought,” said Daniel Swain, a climate scientist at the University of California. “It’s the persistence of this ridge during the winter months.”
Although the study doesn’t attempt to explain the most recent drought, Cvijanovic said that examining past droughts illustrates what Californians should prepare for in the near future.
The researchers simulated an ice-free Arctic season and compared the model with the sea ice conditions at the end of the twentieth century, showing how the changes reverberated across the planet and diverted rainfall from drought stricken California.
“While more research should be done, we should be aware that an increasing number of studies, including this one, suggest that the loss of Arctic sea ice cover is not only a problem for remote Arctic communities, but could affect millions of people worldwide. Arctic sea ice loss could affect us, right here in California,” said Cvijanovic.

Snapchat parent company Snap Inc. is bringing its camera-equipped Spectacles to the UK for the first time in partnership with pop-up mall Boxpark, located in the Shoreditch district of East London. The news, announced on Boxpark’s website today, comes on the heels of Snap’s less-than-stellar earnings report on Tuesday, in which the company said it lost $ 40 million on unsold units due to “excess inventory reserves and inventory purchase commitment cancellation charges.”
It’s not clear this will have a drastic effect on the company’s excess Spectacles inventory, which appears like it amounts to hundreds of thousands of unsold units, according to an earlier report in October from The Information. Although this will mark Snap’s first fixed…
Magisk was previously updated to support Google’s Pixel devices, as well as any other phones that might use the recently-implemented A/B partitioning scheme. But, there was one hiccup. It turns out that the Magisk daemon running in the background can die, leading to a temporary loss of root, and it doesn’t get restarted. But this latest update, v14.3, introduces a new “Invincible mode” that should fix all that.
The issue was widely reported, and even we were affected.
Magisk v14.3 beta released with new ‘Invincible mode’ fix for root loss, among other changes was written by the awesome team at Android Police.
