What are the browser and computer requirements for Canvas?. Here are a couple resources I found to help update your browser:

I would add that Safari for a Mac gets updated by updating the operating system. If someone is using a really old version of MacOS, then they will not be able to obtain the latest versions of the browsers until they upgrade the operating system. Upgrading a Mac operating system is a big download and takes a while, so I would not start there, but I wanted to mention it in case you run into problems updating the browser.
I mention Mac because browser support depends on the operating system, but keeping the computer's operating system up to date is a good idea for both Windows and Mac.
