I'm using the old 2.5amp supply with adapter.
Don't need the extra power for USB HD yet.
Power supply is not the same as charger.
And USB-C PS/Chargers might do bad stuff.
Why fix something that might not work on all those third party PS/Chargers.
Get the official 3amp one(when available) and support the RPF?
Or recall all Pi4's?
Those who can afford a Macbook don't have any money spare for the Official supply?
But yep rev 5.0 of the PCB is in the works?
