Hello The downloaded app is unzipped by the MAC's own unzipping utility and does not open. The Mac immediately informs you that the app is corrupted and tells you to delete it. (I'm currently running macOS Monterey 12.6) I used the "The Unarchiver" app to unzip (it's available in the App Store to download), it was successful, EasyEDA opened normally (it always gives the message that the app is from an unknown developer, but just press the "alt" button, right mouse click open. Mac asks if you want to open anyway, just confirm and use). I leave this tip for the community! Perhaps on other occasions where this same problem occurs, this could be a solution. Sorry if there were any grammar mistakes, I'm Brazilian, I'm using a translator! Thank you all!! Bruno Souza
