High Sierra firmware suggests Secure Enclave, Intel 'Purley' chips coming to iMac Pro

A report on Thursday suggests Apple's forthcoming iMac Pro all-in-one will run Intel's server-class "Purley" Xeon platform, as well as a Secure Enclave Processor similar in function to the ARM-based chip embedded in the MacBook Pro with Touch Bar.

According to Pike's Universum, code in the latest macOS 10.13 High Sierra beta release suggests iMac Pro will be Apple's first desktop to feature Secure Enclave integration.

Borrowed from the iOS line of products, Secure Enclave Processor technology was introduced to the Mac platform with the MacBook Pro with Touch Bar late last year. Like its iPhone and iPad siblings, the MacBook Pro uses an ARM processor to authenticate Touch ID operations.

Today's report notes Secure Enclave compatibility will extend to a variety of system-level hardware and software functions including AppleSecureBootPolicy, ApECID, ApChipID, ApBoardID, ApSecurityDomain, ApProductionStatus and ApSecurityMode. The presence of a Secure Enclave also opens the door to Touch ID access, though Apple did not mention such capabilities when it previewed iMac Pro at WWDC.

As for processors, High Sierra code points to the use of Intel's LGA3647 socket, a server-grade component reserved for the Purley Xeon platform. Purley is based on the Xeon E5 and E7 platforms and supports high-end Skylake class Xeon silicon. The information lines up with Apple's promise to equip the desktop with 8-, 10- or 18-core Xeon processors. Entry-level 8-core versions are expected to start at $4,999.

Pike's Universum also found reference to Intel's Basin Falls chipset, high-end hardware that supports the chipmaker's new Core X-Series processors. The X299 chipset is interoperable with Kaby Lake-X and Skylake-X parts, the latter of which is being offered with up to 18 cores.

Beyond the inclusion of Xeon processors and Radeon Pro Vega GPUs, Apple has said very little about iMac Pro's specifications. The company is expected to provide more detail as the desktop's December launch date nears.

But will it only be accessible via the iMac Pro? I'm hoping Apple has worked out the additional logistics, security, power draw, and wireless bandwidth to make a Touch Bar with Touch ID and Apple Pay on a wireless keyboard.

We tried to get some details out of this guy at WWDC 2017. He was a rock that wouldn’t break! I can tell you it looks awesome!

I plan to buy one without hesitation, even after being horribly betrayed with the UltraFine BS, but they had better not use the ASIC/ARm coprocessor to lockout the Hackintosh crowd (which is mainly composed of people who can't afford to pay for Apple's quality or have special needs that Apple isn't willing to address), at least not without offering them an alternative (like open/cheap macMinis and a RPi-like board).

Can't wait to get mine. The only thing I am worrying about is 4TB SSD and how much it will add up.

I seriously doubt Apple doesn't really give a shit about the Hackintosh community. At the same time, I doubt they're concerned about it either. Its not like most people are willing to go through all of the crap you have to in order to make a Hackintosh and keep it running properly. The people who really need to use a Mac for work will just buy one because well, time is money and most don't have time to continuously screw around with a Hackintosh. 

I wish I would just get a regular 27" iMac in Space Gray. I'm kinda sick of the current design. Its been the same way for years now. Just something simple like a space gray model changes that.
