For Mac, you may need to enable SSLv3 support for java by editing the /lib/security/java.security in your Java installation directory, and comment out the line "jdk.tls.disabledAlgorithms=SSLv3"
I don't recommend that though as it allows any site with SSLv3 to use Java, and SSLv3 is a vulnerable protocol. Using something like VMware fusion to run the VM in unity mode is the more secure option.
