Thank you Claude. I'm looking for a way to help a visual impaired friend. We would like to write an app that would modify windows' title of other apps (at runtime) and also the main menu of other apps as well (the one on the menu bar). As far as I'm concern, I don' think the macOS will let me do that. I've spend a fair amount of time reading and exploring classes but didn't succeed to find a way to do what I want. That's why I'm asking here hoping an Apple engineer (or some knowledgeable folk) will give me a definitive answer without having me pay 99$ to become a member of the ADP to file a Technical Support Incident (TSI) or find another way to get an answer. Thank you so very much to anyone who can give me a definitive answer. Luke

Hi @EtreSoft, I looked at accessibility features but didn't find a way to access windows of other apps not the main menu of other apps. Did I miss something ??

@Claude31 It'a a third party !!

@Claude31 Merci beaucoup Claude. Je vais relancer les ingénieurs Apple directement ici avec un nouveau 'post' et voir si j'obtient une réponse. De fait, les ingénieurs d'Apple s'impliquent-ils ici ou sommes nous laissés à nous-mêmes ? Luc

Thanks. I've spend a fair amount of time trying to find a way for an app to modify the main menu (the File Edit ... Help - of the menu bar) of *any* other app. As far as I know, Apple won't let an app do that. Can someone confirm ?
