I have a mac and now that flash player is no longer available i am unable to record a video for a job application.
Is there any alternative?
There are many ways to record videos that don't need Flash. The one you have can no longer be used.
If you're using video recording website from the potential employer, there's nothing you can do. The potential employer needs to find new video recording software.
If you're using you're own video recording software, as OP mentioned there's other options avaialble.
Major browser vendors are deprecating Flash Player support. Details specific to each vendor:
