I searched online and it looks like it's a common problem on Apple Silicon. I also tried to: export CPPFLAGS="-DPNG_ARM_NEON_OPT=0" before trying to install, to no avail. Thanks!

Thanks for reporting! While this is fixed (I may take a look, but @EricFromCanada knows better), you may try the cask with brew install --cask lisaem. I've seen that it crashes upon quitting: please report any other issues.

Hi, the cask installs just fine, thank you.
