  • M1 Mac mini teardown reveals smaller logic board, non-upgradeable RAM

    The RAM is separate to the SOC? Interesting.
    Apple is attaching the RAM to the SoC's package for performance. The RAM isn't part of the SoC itself. On phones this sort of package sometimes stacks the RAM on top of the SoC, but the M1 evidently puts the RAM on the side to better manage heat (and allow for things to get hotter without cooking the RAM). 

  • M1 Macs deliver Apple's first support for USB4

    Lmao, so I see Appleinsider continues to publish fake news.

    The entire premise of this article is false. Tiger Lake laptops (which include Thunderbolt 4) were released in late October. Thunderbolt 4 includes USB4, but it's faster.



    No, Apple was not first. Does anyone here do any research before writing an "article"?
    Do you have a real link to USB4 laptops currently on sale? Your first from September points to a model that was expected to arrive in October, but searching Asus brings up USB 3.x models. The other is from January.

    The USB 4 name is misleading. It's technically correct because the new specification doesn't mandate supporting the fastest speed (40 Gbps). The actual supported USB speed is 10 Gbps on the new Macbooks, just like on the old ones. It's exactly the same "USB 3.2 gen 2".
    USB 4 is effectively TB3 converted to the USB spec for licensing. 

    Apple's M1 is the first hardware licensed to deliver "USB 4." It also supports USB 3.2 g2. So there aren't really USB 4 peripherals out there yet. And if its supports TB 3 at 40Gpbs, what makes you think the top speed is 10?

    How do we get an iPad app on our M1 computer?
    Developers make them available in the Mac App Store, and you download them.
    If you already have the app, you can even use automatic downloads to keep your M1 Mac up to date. 

    There isn't a way to share apps directly from your device to the desktop tho. 
  • What the Apple Silicon M1 means for the future of Apple's Macs

    What specific things will the Apple Silicon Mac’s not be able to do that the preceding Mac’s could?
    Obviously we won’t be able to BootCamp and run 32-bit applications with an older system, but what else will not be possible?
    Will we still be able to boot off an external device? I assume with the integration of system memory that memory upgrades on desktop Macs will be a thing of the past too. So much for getting around Apple’s overpriced memory premiums, or will this be still possible somehow? What might this mean for PCI based expansion cards? Will these still work when in a thunderbolt enclosure or directly installed in a Mac Pro? 
    It’s an exciting new step but I will like to know how these things will be restricted too. Faster is good, but is it still extendable like our current and past Macs or are these more commoditized devices that will run Mac software but not the same types of Hardware?
    Some of the limitations you're seeing are also present in the models replaced. Intel MBA shipped with 8 or 16 GB RAM unexpandable. 
    Thunderbolt essentially is a PCIe slot over a cable. Until now, it was an Intel technology that required Intel silicon (a TB controller chip). That's why iPad Pro doesn't support TB3.

    With the new TB4 spec, Intel decided to begin licensing it like USB, and allowing third parties to implement their own controller. Apple created support for TB (apparently lacking full support for the whole new TB4 spec, as it only calls it TB, plus USB4. This suggests that future Apple Silicon Macs could perhaps support PCIe compatible slots or TB-based connectivity to external PCIe slots. M1 Macs do not support eGPUs (PCIe GPU cards in an external box connected by TB), but that's could be simply because it hasn't been implemented yet. It also might not ever make sense for Apple to do the work to support eGPUs, giving it a monopoly over Mac GPUs. Seems like this is not what Apple is trying to do here tho.
