I'm trying to install orca 6 for chemical computations. I'm using MacBook Pro with the M4 Max chip. I've tried using both

macOS isn't Linux, so Linux installers obviously won't work.

The macOS installer is running into a problem with the bzip2 executable:

line 308: /opt/local/bin/bzip2: Bad CPU type in executable ... Decompression failed

Which suggests the executable is an Intel version, not an ARM version. Your package manager (Macports?) needs to be updated/reconfigured so it installs ARM versions, but that's a different issue to solve.

You can try running the installer using the system-installed version of bzip2 by fixing $PATH:

env PATH=/bin:/sbin:/usr/bin:$PATH ./orca_6_0_1_macosx_arm64_openmpi411.run
