Although Apple promised that the transition of Macs from Intel processors to Apple processors would be completed in 2 years, it missed the two-year deadline.
When Apple silicon was launched in 2020, the company committed to a two-year transition away from Intel processors . Today marks the first day of the third year of that transformation, but the Mac Pro still uses Intel chips . Apple missed its deadline.
There has been no mention from Apple about replacing the processors in macOS with the M series. However, some details have leaked.
It was June 2020 when Cupertino officially announced that Macs were moving away from Intel. Details were sketchy at the time — the unveiling of the M1 was still months away — but Apple promised that “the first system will ship by the end of the year, beginning a two-year transition.

The “first system” turned out to be the MacBook Pro running the M1. Or maybe it was the Mac mini using the same chip. Both were released on November 10, 2020. It’s now been two years since then, and with the Mac Pro still running processors , the transition clearly won’t be as quick as Apple.
That said, Apple gave itself some leeway, stating in its June 2020 announcement text that it would "complete the transition in approximately two years."
When will the M-Series Mac Pro be here?
There would be less room for excuses for missing the deadline if there was a timeline for when the next macOS workstation would be released . Even a hint. But Apple hasn't said anything about it.
That leaves anyone looking to buy the Mac Pro with an M-series processor to guess. It could launch in March 2023, when Apple's M2 Pro or M2 Max. Or the wait could be until early summer.
It's true that the Mac Studio released in early 2022 offers more power than the 2019 Mac Pro — the benchmark puts it at 16% faster. But that's not a huge improvement over a 3-year-old system. And professionals who, for example, create hours of 3D videowill want even more power.

Apple is apparently working on delivering. Leaks from Cupertino suggest that the processor in development for the next Mac Pro will be twice as powerful or even four times as powerful as the Apple M2 Max chip that will be released in MacBook Pro models expected in early 2023.
Given this description, the upcoming top-of-the-line processor will likely be available with 24 or 48 CPU cores and 76 or 152 GPU cores. For comparison, the most powerful version of the current Mac Pro features an Intel Xeon W with 28 CPU cores.
When the M-series Mac Pro finally launches, it will complete the transition that began in 2020
