I am lost by your qeustion as it is unclear. Are you asking regarding the Desktop manager. Because if that is the case then, NO it will not work with a mac.
Desktop Manager does not work for connecting a Mac and a BB. Windows only. However, PocketMac is what you use to connect to a Mac - and is available through the BB website.
Ive had no problem downloading programs to my blackberry using pocketmac. Theres a menu called "install application" and you find the app on your mac and then it will install to your berry. You can uninstall as well. I have loaded many themes this way.
