Newer versions of Mac computers that operate with the M1 chip will need an additional program provided by Apple, called Rosetta, in order for you to install and run our BitBoxApp on your computer.
If your Mac does not automatically try to open the BitBoxApp using Rosetta, find the BitBoxApp in Finder, right-click on it, select "Get Info" and check the "Open using Rosetta" option.
Then try launching the BitBoxApp again.
You may find further information about Rosetta here.
