Comment (by mcs):

 Replying to [comment:4 gk]:
 > I wonder how we should handle things if we want to drop support just for
 32bit systems. (See: https://lists.torproject.org/pipermail/tor-
 talk/2014-September/034728.html for my idea) That plan has IMO a bunch of
 advantages and not much disadvantages compared to the "Let's move to 10.7
 as minimum proposal"...

 I think we will be able to detect the difference because of the presence
 of the %BUILD_TARGET% component within our update URL (we do not plan to
 remove that component).  In TB 4.0a2 that component turns into this:
   Darwin_x86-gcc3
 I think it will turn into the following in a 64-bit build (we will need to
 test to be 100% sure):
   Darwin_x86_64-gcc3
 Then we just need to modify boklm's tb-update-response script to return a
 "end of life" XML response if _64 is missing.  In the simplest case, that
 can look like:
 {{{
 <?xml version="1.0"?>
 <updates>
     <update unsupported="true" detailsURL="..." />
 </updates>
 }}}
 The detailsURL should point to a helpful page that tells people they need
 to stop using Tor Browser on their outdated systems.

 Also worth noting: Google is apparently dropping their 32-bit Mac builds:
 http://blog.chromium.org/2014/08/mac-chrome-when-im-sixty-four-bits.html
 (or rather, they are switching from 32 to 64 like we may do).
