Yes, but that will block the UI. The progress bar update (world rendering) is done by force using “self currentWorld displayWorld”, which also means that if the #do:displayingProgress: is forked there will be more than one UI rendering at the same time.
Open a window, evaluate the script below, drag and drop the window around.

Hi all, is there an easy was to do some thing that is constantly changing? so if my image freezes (to export a 1gb ston file for example) I can see when it’s done. Or maybe there is a way to send a mac notification from Pharo? Cheers. Uko
