Apple has discontinued the Mac Pro with no replacement planned. The move ends a 20-year run for Apple’s most expandable desktop, though the Mac Studio and Thunderbolt 5 have made its PCIe-based expandability largely obsolete.

The title says it all—if you have a Mac Studio powered by an M3 Ultra chip, you cannot upgrade to macOS 26 Tahoe at this time. macOS 15.7 Sequoia will install, or you can wait until Apple resolves the issue.

Apple has updated the Mac Studio for the first time since 2023, replacing the M2 Max and M2 Ultra chips with the M4 Max and M3 Ultra. The new models offer significant performance gains, increase maximum memory from 192 GB to 512 GB, boost storage limits from 8 TB to 16 TB, and add Thunderbolt 5 connectivity.

With the release of the M2 Ultra-based Mac Pro alongside a new 15-inch MacBook Air and upgraded Mac Studio, Apple has completed its promised transition of moving the entire Mac line to Apple silicon.

Apple has unveiled its latest Apple silicon chips, the M2 Pro and M2 Max, and announced new M2 and M2 Pro models of the Mac mini, plus M2 Pro and M2 Max models of the 14-inch and 16-inch MacBook Pro.

Some repair enthusiasts have accused Apple of deliberately preventing SSD upgrades in the Mac Studio. That isn’t the case, though the truth is complicated.

When Apple unveiled the new Mac Studio and Studio Display, it also quietly dropped the venerable 27-inch iMac from the product line. Those who have been waiting for an Apple silicon 27-inch iMac are disappointed, but as Adam Engst shows (with lots of charts), there are plenty of other good options in the Mac lineup.

Apple has introduced a new Mac model—the Mac Studio—powered by its most powerful chips yet, the M1 Max and new M1 Ultra. But for Adam Engst, the most exciting announcement of the day is the new 27-inch Studio Display, which pairs well with any of Apple’s M1-based Macs.
