Take the tour ×  How long does Apple normally support versions
of OSX with security updates. What was the last OSX version to
drop support for security updates? Where would I find this
information?  share|improve this question add comment  2 Answers
up vote 7 down vote accepted  Currently Apple supplies security
updates for the current OS version and one previous version. The
supported OS versions are Snow Leopard and Lion at this time.
Leopard security updates stopped when Lion was released.
