Can the 1M chip be installed into my 2019 MacBook Pro?

The M1 chip is a computer specific SOC (System on Chip), so because of that you can't install it into a computer that does not already have it. It is also important to note that the M1 chip is not sold by its self, but instead is included in most modern Macs.

So sadly, it would not be possible to upgrade your current MacBook Pro to M1. Apple does sell MacBook Pros that are already based M1 & M2 chips, which would be your only option.

Hope this helps in some way!

If there were any, Readers here would be the first to report that they were available.

At this writing, there are no know Apple or third-party upgrades of Intel Macs to Apple-silicon Macs, for any models, except complete replacement..

No.
