  • Intel details Thunderbolt 4 spec, but 'Apple silicon' support is unclear [u]

    As a standard, Thunderbolt in all its iterations is an abject failure for two reasons: No affordable devices supported it and the selection was extremely limited. Thunderbolt was only found on external SSD drives that cost about twice as much as the USB 3 versions and often offered little additional performance. USB on the other hand has been a staggering success. When people purchase a new computer, the first thing they often look for is how many USB C 3.2 ports they offer. It works with everything (including Thunderbolt) and is frequently updated with additional speed/features. The only thing you have to watch out for are shady cables on Amazon (pay a bit extra and buy from a reputable brand). If you really want Thunderbolt, buy an add in card for your Mac Pro.
    You seem to know what everyone else is looking for eh?

    For those that do actual work on their machines, particularly those that depend on them to generate revenue for their business, Thunderbolt is a no-brainer.

  • Apple surveying users about iPhone AC adapters amid rumors they'll be sold separately

    Even I have to say that Apple is being rather petty here.  I too have plenty of old chargers from prior iPhones and iPads.  I'm planning on buying the iPhone 12 and I expect not only a power adapter included with what will be a very expensive phone, but one of the highest wattage models available.  That way, I can retire the older, obsolete models.

    Considering how much these chargers costs Apple to make compared to the entire cost of an iPhone, I as a consumer should decide what to do with my charger, and not Apple.

    Yes, and those I have deemed as too unreliable, with quality issues, thermal issues, firmware issues, and sketchy compatibility issues with flavors of MacOS.  I’ve been wanting an external, portable TB drive but nothing on the market provided me with a comfortable feeling.

    hope this one does.
    So, I have a 2014 iMac with Fusion drive. and i'm wondering if it would make sense to use something like the linked device above as a boot drive. 
    I have a 2015 iMac and it only has TB2 along with a Fusion drive. 

    From MacSales: Besides being the industry’s first Thunderbolt™ 3 bus powered (no power adapter required) enclosure... 1553MB/s performance based on testing a 2.0TB OWC Aura Pro P12 equipped Envoy Express

    I'm not sure if the Apple TB2 to TB3 adapter works as a powered port. I have the adapter but it's connected to a TB3 RAID, which is powered.

    The SSD blade used in the photo doesn't match the photos used by MacSales for either their 6G or NVMe blades so I'm not sure which blade they're actually using. The NVMe blade, https://eshop.macsales.com/item/OWC/S3DN3P2T20/, is rated at 3400/3000MB/s so this enclosure doesn't use the full speed interface like their Envoy Pro EX which has 2500MB/s speeds. The 1500 is nothing to complain about but you might not get that speed using TB2. I presume the internal port is a USB-C, which your iMac doesn't have.

    Even though I only have a TB2 iMac I'm going to go ahead and get the enclosure and check it's speed when connected to my TB3 RAID (connected to my iMac using Apple's adapter). Pricing for their Envoy Pro EX, 2TB model is $499.75 while their 2TB NVMe card is $348.99, add the $68 for the enclosure and it's $416.99, a good savings but it is slower than the Pro E, which doesn't work with the Apple adapter (confirmed by MacSales).

    Ordered: expected delivery August 2020
    Thunderbolt2's 20gb/s bandwidth = 2.5GB/s.  TB3's 40gb/s = 5GB/s.  Granted, OWC's 1.5GB/s is still extremely fast for an external drive, I wonder if the bottleneck is the SSD drive itself, and not the enclosure.  The Samsung 970 Evo is rated at 3.5GB/s read and 2.5GB/s write.  Will this enclosure not utilize that speed if I use that SSD?  I hate these kind of uncertainties.

    I'm curing about your setup.  Your 2015 iMac has a TB2 interface, yet you're using a TB3 RAID array?  What adapter are you using?  Apple's adapter allows TB2 devices (like the Thunderbolt monitors I use) to connect to a TB3 system.  Not the other other way around like yours.  Can you explain your method?  I'm been looking for such a solution.

    Ok, I don’t get it.  I watched the keynote and could have sworn that I saw Parallels Desktop being run on their ARM Mac to show Linux running...or did I imagine that?
    They were using Linux compiled for ARM architecture.  

    I don't think this news really surprises anyone running Windows on MacOS.  I use VMWare to run several versions of Windows when MacOS goes all ARM exclusively way down the road, I may have to buy a Wintel PC for those times I need it.  

    I was planning on buying an iMac this year, I still might... it might be the last Intel Mac machine I'll get, and it's primarily because I still need Windows compatibility for my non-Mac development tools.
