Considering that Airplay is disabled for older hardware since the CPUs
don't have required functionality, it looks like Safari has the same
restriction.
I think Apple should have provided software emulation for the missing
CPU instruction for older hardware so that applications would run
normally. I know that Digital did that for the MicrovaxII whose chip did
not implement the full VAX instruction set and some of the instructions
were emulated by the OS.
Firefox is supported on Windows but not on Mac. Considering that video
decoding is likelyt part of common code between platfdorms, I would have
assumed all Firefox platforms would have been supported.
Note that Netflix suypports HTML5 on Chrome all the way back to Snow
Leopard.
Google last week disabled the "Earth" view for my Mac. Am back to
satellite view only, and a "zombie" mode that is neither "full" nor
"lite" modes. Ironically, using Safari, I can switch to lite mode, and
then back to full mode and I then get Earth back. But in Firefox, I
can't switch to Lite mode because the icon isn't there.
