Last week, Geertjan Wielenga helped me resolve a NetBeans 8.2 problem I was having with the Kotlin plugin on my MacBook Air.
Then he suggested I upgrade to NetBeans 11.1. I downloaded the ZIP file and expanded it. In the bin folder, there are three executable files, though two of them are for Windows. When I click on the first file, identified as a "Unix executable," I get this message: *“netbeans” can’t be opened because it is from an unidentified developer.* Your security preferences allow installation of only apps from the App Store and identified developers. Opera downloaded this file on September 19, 2019 from *mirror.olnevhost.net <http://mirror.olnevhost.net>*. The OS is Mac OS Mojave 10.14.6. I can certainly go into System Preferences and tell it to open NetBeans 11.1 anyway. I could also relax the security preferences. But maybe some caution is warranted, and I don't recall having to do this with NetBeans 8.2 earlier this year (or maybe I did but I don't remember now). Geertjan says there's no need to change or override any security settings. Did I take a wrong turn somewhere?
