hello the wallet is showing me a warning sign saying the check point is to old wait for block chain to download or notify developers I've read the forum and assumed the recent link on mega upload was the answer to the solution but there is no application to open the zip i am currently using the mac version 10.9.5 not the yosemite

The warning sign is something that will be resolved with the next update. It is not an issue that needs to be resolved in a flash.
For opening .zip files on a mac you can use Zipeg
