The just-launched 2023 Mac Pro lacks features considered critical for workstations: upgradable RAM and support for eGPUs. But this isn’t Apple blindly making an error — it’s an inescapable fact of the M-series’ unified memory architecture.

The limitation isn’t new: it’s been known since the M1 processor was announced. But Tuesday’s release of a top-tier macOS workstation shines a spotlight on the problem.

For those who weren’t paying attention back in 2020, here’s an explanation of why RAM upgrades and plug-in GPU aren’t an option for the 2023 Mac Pro.

A high-level Apple executive says an upgraded Mac Pro is on the way, even if he did so in a backhanded way.

The company’s VP of Worldwide Product Marketing said in an interview that his company has “a clear goal to transition fully to Apple silicon.” That’s an oblique reference to the Mac Pro, the only macOS computer still running an Intel processor. A replacement with an Apple M-series chip could be out in mere weeks.

TSMC is going large with its Arizona plant. The Taiwanese company that makes processors for almost every type of Apple device committed itself to putting $3.5 billion into its U.S. subsidiary. And that’s only part of the eventual cost.

Apple has already promised to use chips made at the plant.

Taiwan Semiconductor Manufacturing Company began cranking out chips using its new 3nm process Thursday at its Tainan plant. But, never one to rest on its laurels, TSMC is already laying the groundwork for 2nm processors.

Apple is expected to be among the first companies to benefit from the cutting-edge chips, which will be faster while requiring less power.

Apple CEO Tim Cook said Tuesday that his company will buy processors made in Arizona by TSMC, which currently produces Apple’s most sophisticated chips primarily in Taiwan.

Plus, Taiwan Semiconductor Manufacturing Company revealed that it will pour even more billions into Arizona by adding a second chip factory in the state.

At the launch of Apple silicon in 2020, the Mac-maker committed itself to a two-year transition away from Intel processors. Today marks the first day of year three of that transformation but the Mac Pro still uses Intel chips. Apple missed its deadline.

There has not even been a mention from Apple of a replacement macOS workstation with an M-series processor. A few leaked details are all we have.

The M-series processor in the upcoming Mac Pro desktop will reportedly give it a dramatic speed boost. It could be “at least” 2x or 4x as powerful as Apple’s upcoming M2 Max chip for high-end MacBooks.

The previous Pro desktop is the last in Apple’s product lineup still designed around an Intel chip. Apple is allegedly building processors that can beat it.

Many of the best features of iPadOS 16 like Stage Manager are only coming to the M1 iPads. This angered a lot of non-M1 iPad users since they believe Apple is intentionally trying to limit the feature to newer devices.

The company has now provided an in-depth technical explanation behind Stage Manager not coming to older iPads.

The Apple M2 processor hasn’t yet been released and the first report of an M3-based Mac is already out. It could launch as soon as 2023.

This might be an indication that Apple will release new versions of its Mac/iPad chip more quickly than it has until now.

iPhones will continue getting smaller, faster and more efficient processors for years to come. TSMC, the company that manufactures all Apple’s chips, says it should be able produce processors in 2025 that are an amazing 2nm. These should make today’s fastest Macs and iPhones look like slugs in comparison.

Rival Intel is working hard to keep up. It says it’ll pass TSMC in a few years – but it’s missed plenty of similar self-imposed deadlines over the years.
