    I’m not likely understanding some of this story. One key statement is there is no firmware fix. Looking on Intels site, they have a table listing each cpu, and the minimum ME firmware version that resolves the issue, or at least one of the issues. 

    Like one of the other commenters, I too, in December, purchased a new mbp but also an new iMac. The About My MAC doesn’t describe the cpu level of detail about its firmware versions to know whether my chips have the latest firmware versions. It’s goimg to be Apple’s resonsibilty to push out the firmware updates. 

    A second thing to note. Intel has downloadable software to analyze your system for these flaws, but the software only runs under windows or Linux. Intel needs to push out a version for macOS. 
    I tested the tool on a Mid-2015 Retina Macbook Pro 15" under BootCamp. It outputs the following information:

    Name: <your computer's name>
    Manufacturer: Apple Inc.
    Model: MacBookPro11,5
    Processor Name: Intel(R) Core(TM) i7-4870HQ CPU @ 2.50GHz
    OS Version: Microsoft Windows 8.1 Pro
    Engine: Intel(R) Management Engine
    Version: 9.1.20.1035
    SVN: 1
    Status: This system is not vulnerable.

    Other Macs may be vulnerable or not. If any Mac is vulnerable of course Apple will issue a system update.

    For the curious, here is Intel's official response. Tired of playing the voluntary reporter. Why don't you update your article AI?

    According to early reports, the flaw allows to make some kernel-specific VM pages accessible from the user space, using some techniques not disclosed yet. Not writing critical information to VM pages is the ABC of kernel programming in Apple development culture, critical information must be held in wired memory that cannot be paged. That flaw and the potential exploits are probably already known by operating system developers so that saga may end up with nothing. Forget class actions and alike...

    No one would notice that minus 0.3 GHz in real life usage. The stock throttles more than that 0.3 GHz by the way...

    “the clock speed to drop from 3.9GHz to about 3.6GHz for a second or two. This allowed the CPU to drop below 92 degrees, and the clock speed to rise back to the maximum 3.9GHz”
    The stock Xeon W-2145 is supposed to turbo to 4.5 GHz and will not throttle. Most desktop cooling solutions can likely sustain even higher frequencies without throttling.

    Apple's solution is downclocked and still throttles.
    Turbo is for single core, dude...

    So your (mis)understanding "how may it throttle at 3.9 while it can Turbo at 4.5" doesn't make sense, you compare apples to oranges.

    The thermal throttling is a huge problem in a professional machine.   Sadly AI is seeing throttling in extremely light usage imagine how much you would loose over 8 hours.

    Frankly this is not unexpected!   Apples history with the word "pro" and cramming hot parts into a tight enclosure isnt good.  Every day im becoming more and more convinced that Apple just doesnt understand the "PRO" market.  
    Hot parts in a tight enclosure hold less heat. There is a reason Apple choose aluminum for enclosure: to dissipate heat faster. This is also the reason Apple makes iMacs and Macbooks thinner. That thinness serves to dissipate heat by natural means. The thinnest Retina Macbook is one of the first fanless computers.

  • iOS apps on macOS would bring hope for Apple Watch, Apple Health support on Mac

    I would be quite happy if my Health and HomeKit data could be synced and backed up locally. I prefer to set up my iPhones as new but doing so currently means I would lose all that Health data history. 

    Back up your health data to iCloud, it is in the Settings. And don’t forget to unpair your Apple Watch whenever you change or restore your iPhone, so that your health data gets backed up during unpairing.
