Hi Peter,
I’d like to answer your questions one by one.
1. Yes. The official desktop SkyDrive Pro client for Mac has not been provided.
2. The app for iOS has been lunched. However, Android has not been supported yet.
3. I’m sorry but officially we have not received related news about the launch time.
SkyDrive Pro is cloud storage that organizations provision for employees as part of their SharePoint 2013 on-premises and/or Office 365 SharePoint Online deployments. I understand this may be of much importance to your business. As it is a tool for a new feature, it may need time to support all platforms. We do try our best to satisfy users’ requirements. Initially, in Windows, SkyDrive Pro app could only be got via Office 2013. Now we have provided the standalone download. I think more and more platforms will be supported in the future so customers under various situations can use this service. You can also send feedback to our product team via the following link.

Hope the app for Mac and Android will be available in the future so that your requirement can be met. Thanks for your understanding.
Best Regards,
Kevin Cui
