I wasn’t able to pre-order the 13 Pro Max last year and started checking local Apple stores for stock about a week after launch. It took over a month before I was able to find the model I wanted in stock (I wasn’t fussed about colour, it was just the memory capacity) and online delivery dates were even longer. Third party may have been different but I prefer to buy direct from Apple.They really have not been that hard to get hold of for the last few launches. The lead time was only a couple of weeks from Apple at the most and usually available to walk in and buy from 3rd party sellers/networks.
My Studio Ultra is on a twelve week delivery time, the display eight to nine weeks (and is likely to be delayed) and I looked at a 14” MBP a couple of days ago and the wait time is somewhat surprising.Just look at the lead times for their MacBook Pro’s and iPad Airs - 2 months and 1 month respectively.
