MacOS by default quarantines all software (it detects, i.e. mostly stuff installed into /Applications) not downloaded through the app store. Normally, at first start you would get a popup stating something like that you have downloaded software from an untrusted source and your security settings don't allow execution of such. However, this only works if the new software tries to start a new window of its own. Polymake however starts *inside the already approved terminal* and so misses the warning.
You can switch off this behaviour globally in your system preferences, though this would not affect the already downloaded polymake. I don't know whether there is an official way to tell MacOS that you trust polymake, but the information is simply stored in an extended attribute of the bundle folder, which you can change in a terminal with
Code: Select all
xattr -r -d com.apple.quarantine /Applications/polymake.app/
