In terms of proof, we have the following:
1. The battery specs have already been filed with the Chinese regulatory database
2. TSMT has resolved some technical difficulties with its part in the mini-LED display production. Yields have increased to 95%.
3. Leaked schematics for the 14” from a partner manufacturing company. Leaked schematics for the new iMac match the new model exactly giving some credibility to the leaked MacBook Pro schematics.
4. Recent report from Apple suppliers that Apple plans to ship the MacBook Pro in Q3 which also matched Mark Gurmans claims of an early summer release.
5. Report of large scale production of M1X back in April. We got a similar report for the M1 back in September which turned up in the MacBook Air, 13” Pro and Mac Mini in November. If timing stays current, Apple should have enough M1X chips on hand for an initial launch supply as of this month.
Of course none of this is hard evidence but taking all of them into account points to these machines being very far into production and possibly nearly ready to ship out. As I said in another post, the battery specs being registered is a pretty big deal! Since the battery needs to be able to fit into the final casing and needs to be able to support all of the chips, fans, screen, etc. having the battery specs finalized means there’s a very good chance everything else has been finalized and sent to manufacturing partners. I HIGHLY doubt that anything this far along will just sit there until November…
There have been rumors of a July 20th event which is starting to sounds more and more likely. In fact for all the hype around WWDC, if we look back at all the rumors and leaks, it would seem that everything was pointing to July all along. We just discounted it since Apple doesn’t usually do a July event… but Apple has no obligation to always do things the same way.
