Hello. Running from OS Catalina, the latest version 19.10.18 is unable to open. Thanks!
please search the forum and guides before posting new questions.
Download it again. As long as you download from the official site, it is not corrupted. I’ve downloaded, installed, and run it personally on macOS 10.15. There is, however, a notarization issue. Read this Guide and pay attention to the Note about Catalina: Install or update desktop edition on macOS | Manager.
Hello. I’m so sorry about this, will check more carefully in future and thank you so much for this!
