Some older iZotope products contain an Updater application to keep them up to date, we've replaced this functionality by building it in to our Product Portal.
You can remove the Updater application via the steps below:
Please first close out of all applications on your computer. Then navigate to this file location via your Finder window:
Macintosh_HD/Library/Application_Support/iZotope
Here, please move the "Updater" folder to the Trash and empty your Trash.
Be sure you have Product Portal installed to keep up to date with your iZotope Products!
