Uninstall:

You can unload the add-in without uninstalling it by clicking the "Stop" button when the add-in is selected in the list box on the "Add-Ins" tab of the "Scripts and Add-Ins" dialog.

Unchecking "Run on Startup" causes the add-in not to be loaded in future sessions of Fusion 360.

- Navigate to ./ApplicationsPlugins folder and select the app bundle you want to uninstall

- Either drag the app bundle to the Trash, or right-click and select “Move to Trash”

- Right-click on the Trash-Can and select “Empty Trash”

- If you prefer keystrokes, you can also just select the app bundle and then hit Command+Delete to move the app to Trash, then empty the Trash and the app will be removed.

- Can only read PNG image files.

- Some PNG image files may be corrupt and present the error message "PNG file has invalid signature."  If so, open the PNG image file in an image editing software and re-save the image in PNG format.

- A large number of halftone "Holes" can take a very long time to process and may even cause Fusion 360 to crash.
