With the release of the new ARM macs, they are going to be running some sort of ARM version of Mac OS. Does anyone know if this would work and if so does anybody have any plans to get it running on a Pi 4?
it may or may not.... come back after at least 5 years then we'll know for sure.... ;)

Re: How necessary is extra cooling for the RPi4 now?

Do you even need to mount Pi in a case, or can you just put little feet on the bottom to get it off the desk and using it open-air? as long as a similar scene below can be avoided at all cost.... then it may be OK .

Re: Difference between "push button with two pins", and "button module with three pins"

adding to that.... assuming you have connected the 3.3v and GND to the respective pins on the switch... before actually connecting the "output" pin of the switch to RPI's GPIO, test it first with a multimeter (digital, or analog, whichever you have/prefer). if not pressed... the output should be 0V ...

Re: Difference between "push button with two pins", and "button module with three pins"

based on the description given... it is a push button "module" with an integrated pull-down resistor...

it needs to be wired with 3.3v, GND, and a GPIO input pin (say GPIO5, [pin29]).....

better add a 1kohm resistor between the button module output pin and the GPIO pin....

Re: Why does 1366x768 work on some monitors but not others.

However I was sure I had seen a Pi4 working in 1366x768 with a Pi-top ceed. Wanting to confirm my suspicions I just pulled out my original pi-top (which I assume used the same screen as the ceed) and hooked up a Pi4 to it.
