Apple developed two Mac Pro models in recent years that never made it to market, according to Bloomberg‘s Mark Gurman.
In his latest “Power On” newsletter, Gurman revealed that Apple internally developed two unreleased Mac Pro projects codenamed J170 and J190 before ultimately discontinuing the machine altogether.
As for new Mac Pro hardware, there were two additional models developed by Apple that never saw the light of day: J170 and J190. The former was a new Intel Corp. Mac Pro (yes, even when Apple was making its own silicon) to address certain uses. The latter was an M3 Ultra version that was supposed to launch alongside the M3 Ultra Mac Studio in early 2025.
J170 was apparently a new Intel-based Mac Pro, which is notable because Apple had already completed its transition to Apple silicon by the time the project was in active development. Gurman did not specify what “certain uses” the Intel model was meant to address, but its existence suggests Apple explored keeping an x86 option alive for specific professional workflows even years into the Apple silicon era.
J190, meanwhile, was said to be an M3 Ultra-equipped Mac Pro that was supposed to launch alongside the M3 Ultra Mac Studio in early 2025, but Apple shelved it before release. It would have paired the same chip found in that Mac Studio with the Mac Pro’s unique-to-the-lineup PCIe expansion slots.
Neither model shipped, and Apple discontinued the Mac Pro entirely this year, ending its 20-year run. The Mac Pro had been left on the aging M2 Ultra chip from 2023 while the Mac Studio continued to receive refreshes, and it was priced roughly double that of a similarly configured Mac Studio despite offering essentially the same performance.
The J170 and J190 cancellations add to a growing list of shelved Mac Pro plans. Apple had also developed “Extreme” chip variants, processors with twice the CPU and GPU cores of Apple’s Ultra chips, for a future Mac Pro before winding down those projects over cost and demand concerns.
Gurman said he does not expect Apple to bring back the Mac Pro “anytime soon — if ever.” Apple is instead expected to refresh the Mac Studio with M5 Ultra chips as early as this fall.
