Apple has discontinued the Mac Pro, with no plans for future hardware. The Mac Studio is now positioned as the 'pro' desktop Mac of the future, offering configurations with the M3 Ultra chip and high-end storage options. The discontinuation of the Mac Pro has been seen as a natural step, given the limitations of the Apple Silicon hardware in the Mac Pro's form factor. The Mac Studio is considered a more compelling offering, with options for expansion through Thunderbolt PCIe enclosures.
