Restoring a Bricked iMac Pro Requires a Second Mac and Configurator 2

If an iMac Pro becomes unresponsive and requires restoring, like if there's a power failure during a software update, there are a special set of instructions iMac Pro users must follow, which require a secondary Mac.

As outlined in an Apple Configurator 2 support page, an iMac Pro restore requires a second Mac running macOS High Sierra with internet access and Apple Configurator 2.6 or later installed.

The iMac Pro will need to be connected to the secondary Mac with a Thunderbolt or USB-A or USB-C to USB-C cable. From there, iMac Pro users will need to plug the cable into the Thunderbolt port closest to the Ethernet port and then connect the iMac Pro to power while holding the power button.

Apple Configurator must be used on the second Mac to select the iBridge device and then restore. After the restoration process, the iMac Pro will reboot, making it accessible again.

This restore process is similar to what must be done for an iPhone or iPad that is unresponsive, and it is necessary due to the extra security afforded by the Apple-designed T2 chip.

The iMac Pro's T2 chip is a second generation version of the T1 chip that powers the Touch Bar in the MacBook Pro. The T2 chip integrates the system management controller, image signal processor for the camera, audio controller, SSD controller, a Secure Enclave, and a hardware encryption engine.

Among other improvements, the T2 chip encrypts all of the data on the iMac Pro's SSD using dedicated AES hardware that doesn't impact the performance of the SSD. It also ensures a secure boot up process, making sure no unapproved software loads at startup.

Assuming you can’t bring it in to an Apple store


Unless you live in Montana, Wyoming, the Dakotas, West Virginia, Saskatchewan, any other part of northern Canada, or in any other part of the US or Canada that's not within 200 miles of an Apple Store.

And that's only 2 out of 3 countries in North America, there are plenty of cities around the world without an Apple Store.

Oh, and then let's say there is an Apple Store. There might not be a genius bar appointment available for a few days. If you spend 5 grand MINIMUM on a ****ing computer, you shouldn't have to wait a few days.

or don’t know anybody else who has a Mac....
I don't. All my friends and family are PC people.

This sounds disturbing to me.

I've always treated iOS devices as "appliances", they're basically not "full computers" because you can't run unsigned code on them and you need Apple's permission to install the operating system. (Every time you restore an iOS device it has to authorize with Apple's servers to get an installation key.)

Macs have never had this problem; they've always been "full computers" because you can run whatever you want on them.

Now the iMac Pro requires another Mac to reinstall the OS, which suggests that you need Apple's permission to reinstall the OS, just like on an iOS device. This is scary because it may mean Apple is planning on fully locking down the Mac as a platform.

I'm willing to accept iOS devices as "appliances" but only because I've had my Mac to fall back on as an open computing device. How much longer will that be the case?

Cool so your buying a possible $5,000 to $13,000 paper weight. Unless you speed more money on another Apple computer.

Sick, quite possibly the first "Mac" that you can completely LOCK UP, without any Startup Disk tricks....
