Much as I like my Mac, using it to produce materials for my online teaching has meant that I always have to remember to convert my files to Word and PowerPoint before uploading them to Blackboard. And also, it has not always proved easy to access students' work when it is on PowerPoint. In particular, sound and presenter notes can be elusive when accessing them on my Mac.
But now my elearning colleagues in college have taken pity on me and have helped me download Office 365 Education so that now I can produce and access files more reliably.
There seems to be no getting away from the fact that most students seem to use Word and Powerpoint, and universal access to materials is surely a basic prerequisite of online learning.
The next job for the elearning wizards is to help me decide which apps are most likely to be universally accessible. For example, using Padlet recently I found that not all students could access it, and of those who could, not all could add a comment. Using screencast-o-matic for screencasts works pretty well but sometimes students can't hear the sound - but that could be because they haven't got sound set up correctly. The same issue can arise with synchronous online tutorials.
