Devs Make Progress Getting MacOS Venture Running On Unsupported, Decade-Old Macs

An anonymous reader quotes a report from Ars Technica: Skirting the official macOS system requirements to run new versions of the software on old, unsupported Macs has a rich history. Tools like XPostFacto and LeopardAssist could help old PowerPC Macs run newer versions of Mac OS X, a tradition kept alive in the modern era by dosdude1’s patchers for Sierra, High Sierra, Mojave, and Catalina. For Big Sur and Monterey, the OpenCore Legacy Patcher (OCLP for short) is the best way to get new macOS versions running on old Macs. It’s an offshoot of the OpenCore Hackintosh bootloader, and it’s updated fairly frequently with new features and fixes and compatibility for newer macOS versions. The OCLP developers have admitted that macOS Ventura support will be tough, but they’ve made progress in some crucial areas that should keep some older Macs kicking for a little bit longer.

[…] First, while macOS doesn’t technically include system files for pre-AVX2 Intel CPUs, Apple’s Rosetta 2 software does still include those files, since Rosetta 2 emulates the capabilities of a pre-AVX2 x86 CPU. By extracting and installing those files in Ventura, you can re-enable support on Ivy Bridge and older CPUs without AVX2 instructions. And this week, Grymalyuk showed off another breakthrough: working graphics support on old Metal-capable Macs, including machines as old as the 2014 5K iMac, the 2012 Mac mini, and even the 2008 cheese grater-style Mac Pro tower. The OCLP team still has other challenges to surmount, not least of which will involve automating all of these hacks so that users without a deep technical understanding of macOS’s underpinnings can continue to set up and use the bootloader. Grymalyuk still won’t speculate about a timeframe for official Ventura support in OCLP. But given the progress that has been made so far, it seems likely that people with 2012-and-newer Macs should still be able to run Ventura on their Macs without giving up graphics acceleration or other important features.

YouTuber DIY Project Shrinks M1 Mac Mini By 78%, Without Sacrificing Performance

In a 15-minute-long video, YouTuber Quinn Nelson from Snazzy Labs explains how he managed to shrink the current M1 Mac Mini by 78% without harming performance. 9to5Mac reports: In conclusion, by rearranging the internals and swapping out the power supply, Nelson was able to reduce the size of the Mac mini enclosure by 78%. He organized all the parts inside a 3D-printed body with a mini Mac Pro motif.

The reason that theoretical space savings are so huge is because when Apple released the first round of Apple Silicon computers, they did not change the hardware industrial design at all. So the current Mac Mini enclosure is designed to fit an Intel CPU and circuit board, including having to accommodate the large fans and heat sinks the Intel chip required.

But with the power efficiency of the M1, Apple has the headroom to do something much more drastic. Indeed, a lot of the M1 Mac mini internals is just empty space. The Snazzy Labs video gives a glimpse at what is possible if Apple is more ambitious with the next-generation Mac mini design, and tries to create something truly mini. The CAD files and schematics can be viewed here.

Zoom Update Prevents Microphone From Staying Active After Calls On Mac

Popular video conferencing platform Zoom this week released an important update to its macOS app following user reports about the microphone not being disabled after ending a conference. Luckily, according to the company, this was just a bug that has now been fixed. 9to5Mac reports: Since December last year, a number of users have been complaining about this bug in the Zoom Community (via The Register). According to them, the Mac’s microphone stayed active even after ending a Zoom conference — which certainly raised privacy concerns.

Zoom has confirmed that there was a bug in its macOS app that could cause the orange microphone-in-use indicator to appear even after leaving a call. According to a company representative, the latest version of the app no longer has this problem: “We experienced a bug relating to the Zoom client for macOS, which could show the orange indicator light continue to appear after having left a meeting, call, or webinar. This bug was addressed in the Zoom client for macOS version 5.9.3 and we recommend you update to version 5.9.3 to apply the fix.”

Every M1 Mac Is Due For a 2022 Refresh With Faster M2 Chip, New Designs

According to tech reporter and Apple leaker Mark Gurman, Apple is preparing to launch four M2 Macs throughout 2022. MacWorld reports: The first models will likely arrive later in the year, with the redesigned MacBook Air leading the way, followed by a new 13-inch MacBook Pro, 24-inch iMac, and entry-level Mac mini. A DigiTimes report on Tuesday said the 13-inch MacBook Pro may launch at Apple’s spring event to usher in the new chip. Like 2021, Apple will be releasing Macs with several different chips in 2022. The M2 will be a successor to the M1, likely with the same 8-core design (four performance cores and four efficiency cores), and the M1 Pro and M1 Max will make their way into more high-end Macs. The first of those, the 27-inch iMac, could arrive at Apple’s spring event, with a Mac mini coming later in the year. […] There’s also a new Mac Pro due in 2022 as the culmination of the Apple silicon transition. That would mean every Mac line is due for a refresh this year and nearly every model, with only the recently released 14-inch and 16-inch MacBook Pro escaping without a refresh.
