I have successfully downloaded STS-4 on Mac OS Catalina, but getting the following error when launching it:“SpringToolSuite4” can’t be opened because Apple cannot check it for malicious software. Anyone got a solution to this?
The Spring Tools 4 for Eclipse distribution prior to the just released 4.4.2 version was signed, but not yet notarized by Apple. macOS Catalina requires downloaded apps to be notarized in order to run them directly, therefore you get the mentioned error message.
Spring Tools 4 for Eclipse 4.4.2 got released today and is officially notarized, so you should be able to run that just as-is after downloading.
There also exists a workaround for older versions of the tooling, which can be found in the comments here: https://github.com/spring-projects/sts4/issues/375
Hope this helps!
