the M1 is the cpu not the Gpu mate

you prob have an old 16" Mac from around 2018-2020... It has an integrated low-power Gpu as well as a better one but your Gpu doesn't matter for downloading Dimension

step 1 = have you got a personal [not enterprise or school] Adobe account?

yes = check that you have allow older apps ticked... if its not ticked then the software will not show in the list because Dimension is finished
