I bought an 8GB Macbook Air M1. Since it was for my wife who mostly uses office apps, we didn't bother with the 16GB upgrade.
However, my mac is being repaired and while I wait for it my wife has let me use the M1 machine, which I was greatly looking forward to.
I had also heard that the unified memory was much more efficient, so that 8GB might be enough.
Now, my use case is a bit different to my wife's, but I have had trouble even using it in a cut down way.
I'm a graphic designer and typically I will run Photoshop, InDesign, Illustrator, two or three browsers with dozens of tabs, Thunderbird and Pathfinder.
Just now I got the "Your system has run out of application memory" for the 2nd time today with only Photoshop and not the other two Adobe apps running. This was editing a 350MB (on disk) multi layered photoshop file - a very big file for sure, but not the biggest I would have to work with by any means. No obvious memory leaks, but what happened to virtual memory? Can't I use more than 8GB and have some of it paged??
I'm moving from a 2018 MBP13, but I have also not noticed the M1 machine being especially fast. It wakes up very slowly when attached to an external monitor and usb3 hub, contrary to the keynote 'instant wake' hype. Mouse pointer lags. Scrolling in Firefox and Opera is sometimes jerky.
A lot of the problems seem to be software related, but I can't say I'm impressed with the performance so far, and this is very much not what Apple YouTube led me to believe.
I strongly believe that Apple Silicon is the future, but I'm not absolutely sure it is the best at present.
