    Because your taxes are paying for it anyways once I write it off as a business expense.

    That's not how it works. Deduction is off of income. You still pay most of it....

    So thanks to 10.13, we can no longer use Deploy Studio to re-image machines. With this T2 chip, we can't even Netboot a machine to use a tool like Imagr to install software packages. I'd really like to know when Apple is going to provide a solution to deploy mass quantities of machines, since they keep removing our ability to use the systems that are currently available.

    That iMacPro machine will be paid off many times over, long before that seven year period has gone by, and most Pros who purchase one fully aware it's a 'closed box' they're getting, will be anxiously looking forward to updated hardware equally long before those same seven years are up.

    To wit, read about all the impatience and discontent with the current 4-yr old MacPro.

    Although to be fair, while still a very capable workhorse, that restlessness may partially be due to a lack of meaningful upgradeability of the 'trashcan'. Is that about to change with the coming modular MacPro? Apple hints that way, but I believe there'll be some caveats.

    With the likelihood of FaceID coming to desktops, the likes of embedded T2 chips, amongst other functions encompassing the Secure Enclave, etc., there is that possibility Apple's idea of modular is upgradeability with Apple-approved and/or supplied components exclusively, purportedly to protect the integrity of the security constituents within (and needless to say, their profit margins). Time will tell.

    Aside from all the concerns for hackintosh people (I have no interest in them), this is just a natural path for computing to go in: dedicated/custom chips to do things we no longer want to task the CPU with. That's how it started. Look at older non-PC machines: custom chips galore. Pieces of (or the entirety of) some computers' Operating Systems used to live in ROM, too, which was great for reducing access time to OS code (and a problem with OS upgrades). With the end of Moore's law, something has to take up the task to allow more functionality without bogging down the already burdened no-longer-improving CPUs in our ever bloating operating systems...

    I'd like to know much more about what this chip is doing, beyond the vague overview given.

    I think Control Data's 6000 mainframe series in the 1960's was the first to offload some main cpu tasks (mainly I/O) to it's 10 peripheral processors.

    I fail to see how this changes anything with Hackintosh? We always have control of the boot process on the target computer to get macOS running in the first place. If anything, it's a good incentive to start an iBridge emulation project to replace/complement FakeSMC.

    Let’s say macOS 10.16 can only boot with T2 or later chip, where part of the os is hidden behind the security enclave and encrypted. And OS update images are encrypted as well and only accessible by T2.

    Thanks. I couldn't remember exactly when I posted. The places I checked said the T1 was a T800. My bad for putting in the wrong info!

    My question is what does Apple consider an authorized OS? Are they intending to block the install of Ubuntu or CentOS? If so, that's the final nail in the coffin for Apple hardware for me.

    Your concerns are unwarranted. Apple doesn’t care what OS you run on your Macs. MacOS, Ubuntu, CentOS, Windows, whatever.

    Your purchase of the hardware already paid for a license to MacOS, and free updates for many years... whether you use it or not is up to you. They also don’t care if you use the computer 24/7 or never turn it on again. They got paid what they asked for at time of purchase.

    They were called IOPs and quite difficult to program for as their instruction set was different from the mainframe instruction set. They were cool devices. I had to maintain the IOP that handles tape drives..... Oh the memories of doing that. :eek:

    Just think we used to have to buy an add-on 3D graphics card :O or even a h.264 accelerator card

    Is the SSD encryption mandatory? Can it be turned off or disabled? Thanks.

    It seems that there's no way to control that from the OS. It's an internal function of the T2 which has a built in SSD controller. File Vault can encrypt the drive a second time so that some users cannot read others files, but that's like a second level encryption.

    I would buy one if I needed one.

    You'll note this is the "second generation" T2. The first one was introduced with the second iteration of the Intel based MacBook Pros, the MBP(1,2). It's main purpose was to prevent installation of systems other than OSX or "blessed" MS Windows systems. The net effect was that one couldn't install Linux on those boxes. For various reasons, the T2 chip was removed after about a year, and magically, the UEFI could again be modified to install "non-blessed systems. Well, here we go again ...
