There seems to be ongoing issues when using Canvas through the Safari browser.  I don't know if there is such a thing as a record of the things that won't work, will work with a workaround or will only work using another browser.  Loads of people use Safari and it can be quite frustrating for them and as an Institution, we are hoping to write some specific guidance for problems.  It is difficult for us to test scenarios and it isn't productive going back and forth to the user.  I have looked through questions on the community but can never tell if problems reported were ever fixed.
