Hi, Mark,
Download instructions for Kaltura to your Mac can be found on this page: Kaltura Capture - Installing and Launching the Application | Kaltura Knowledge Center
Kaltura is added into Canvas as an LTI tool. LTI tools can be installed on a per-course basis, or for an entire account. If your institution already has an account, you should be able to access it as soon as you've downloaded it to your computer. If not, please contact your Canvas admin for assistance and see if purchasing Kaltura can be an option. Kaltura has an entire guide about incorporating Kaltura with Canvas: Kaltura Video App for Canvas User Guide | Kaltura Knowledge Center
Thanks!
Erin
