Comment (by cypherpunks):

 > But maybe there is an other way to check for SSE2 support in the start
 script?

 All methods probably stem from /proc/cpuinfo or /sys (which Whonix may
 also restrict).

 > Or maybe we just declare that there aren't any CPUs in daily use anymore
 without SSE2 support and just remove the check?

 That would be reasonable. SSE2 has been a thing for around 18 years now.
 Any non-ancient CPU would have it. The Tor Browser not working would
 probably be the least of their issues with hardware that old.
