Please note that we've already updated Viewer for Mac/Linux and the latest version 1.0.10.q Beta 10 is available for download on this page. Please note that the licensing in the latest version 1.0.10.q Beta 10 works the same as for Viewer for Windows, i.e. you can use Viewer in trial mode for 30 days after which you need to register your Viewer with your license key.
Could you please let us know what version of Viewer for Mac do you use, i.e. if it's the last version currently available (version 1.0.10.q Beta 10)? In addition please let us know what specific version of MacOS do you use as well? We will try to reproduce the issue in our environment to see if we're able to implement a fix for this in our future updates.
I'm also seeing strange keyboard mapping issues as well.
Could you please elaborate a bit on this issue, i.e. what specific keys do you have issues with and their exact behavior?
