Apple’s plunge in PC shipments is steepest among major computer makers
I think Apple being as big, and making the big technological leap with M1 convinced a lot of customers to buy the new Macs. Even those that technically weren’t needing one/upgrade. Now, that curiosity bubble has saturated with the M2 being an iterative improvement and the customer base certainly not as desperate (intel to M1). Given enough time, I think the Macs will continue to gain market share. Most tech companies now  provide MacBooks for their employees as a default choice. One doesn’t lose such grip easily.
