I will be needing to use Zoom for several meetings. I thought I had it set up and did use it successfully twice. Today I went looking for help, and what I saw on YouTube and the Zoom site didn't appear to match what I had loaded. So (perhaps stupidly), I deleted "my" Zoom to start all over. Went to Applications on my MBA and behold! No "straight" Zoom app! Zoom for Safari as close as I saw; no Zoom.us. Where am I suppose to go and what app am I looking for to do basic Zoom conferencing? Why isn't Zoom.us in the MBA Apps? Does Apple not endorse it? More questions likely to follow once I find out what I need to download and from where.
