Downloading iMouse 2.6.4 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. This free Mac application was originally developed by Ninth Space. Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe.
From the developer:
iMouse allows your Mac to have the right-click function like Windows, so you can directly create new documents and other content on the desktop. For Windows to Mac users, it can further improve the user experience, while for MAC users, it is an improvement.
