Playing AVI's in QuickTime
I have an older MacBook Air but I have the new OS Big Sur. I am trying to play large AVI clips from work so I can insert them in a PowerPoint. I am accessing these from my OneDrive however they will not play in QuickTime. I am not sure why since a friend has a MacBook Pro and hers will play when taking the same steps. Any suggestions on how to play and save AVI files to my MacBook Air?
MacBook Air 13″, macOS 11.1
