A combination of strong sales and shortages, I guess?
Not all models affected, but those going for some of the more tricked-out versions (M1 Max, lots of RAM, etc.) may be looking at wait times into early January.
I guess everyone kinda expected this.
No telling what 2022 holds on the redesigned Air, larger iMac and Mac Pro (in addition to any Mac mini updates or rumored “pro” model) fronts. But I’m betting every original plan they had has been shuffled/tweaked a bit at this point.
They might not make their two-year transition plan, if the clock started ticking at WWDC 2020 when they announced all this. However, they could always consider November 2020 the true start of the transition, giving them a nice 5-month buffer, until November 2022, if they wanted.
But I don’t think anyone is truly going to squawk at this point. It isn’t Apple’s fault. And they also know the performance goodness that will arrive when things finally shake out.
