I finally ran into a way to have my M1 Macbook Air’s battery tap out in less than an average workday. It just took a 43MB excel file with over 50,000 matrix functions trying to match up data in some very large spreadsheets. Of course, the machine was still far faster at doing this than my Office Dell with the same amount of RAM as my Macbook Air, which would crash half the time when I tried to load the same excel sheet.
The power of this laptop is staggering. It is scary to think what might be coming when they do the Pro machines.
