i am not a mac expert, but i am certain it would help,
if you could try out one of the recent alpha builds and
report if you get the same message.

i'd suspect that the "repair" is actually doing more damage than
it will help. many, many people have downloaded and installed the
1.8.6 mac binaries and had no problem installing it, so there has
to be something different on your machine or in the way how you
perform that installation that triggers this behavior.

for exactly that reason it would be useful to know, if this is
carries over to the alpha builds.
