On Steam and GOG there have been updates to add support for 2013 CPUs (AVX) and then 2010/2012 CPUs (SSE). Currently the App Store release only has support for the AVX2 instruction set, but support for older CPUs should be added soon in the next game update (which is currently being finalised for testing).
With Steam and GOG, there will also be additional fixes for 2010/2012 Xeon processors in the next update.
