Could the new iMac be an ARM machine to be added to the current Intel-powered lineup?
The existing 21.5” and 27” iMacs would get internal upgrades (SSD instead of fusion, processor bumps) so as to get one more sales year out of them, also leaving them as a safe and known option that would appeal to most consumer buyers.
The new 23” ARM model with the new physical design would serve as a soft launch for the ARM range and, being a single model, wouldn’t immediately threaten sales on the existing product line. It would, however, put the new architecture physically into the hands of the Mac developer community, so they could really go to work building the Mac/ARM software future. No doubt some early-adopter private buyers would also pick one up but devs would be the real target market for this model.
Further, having such a single ARM model out there would also allow any bugs or deficiencies in the design (physical or logical) to surface and be fixed before the new architecture was rolled out en-masse 10-12 months later.
So, a single ARM iMac now, expanding to a full range (totally replacing the Intel machines) some time early-mid next year.
I’d even hazard that a 12” ARM MacBook might appear later this year to serve the same ‘pathfinder’ function in the laptop lines.
