Runtime issues on older versions of macOS

Very old versions of macOS may fail to run modern NetBeans (confirmed for 10.13 High Sierra).

Symptom: Immediate crash on launch (“Apache NetBeans 17 cannot be opened because of a problem”).

Termination Reason: DYLD, [0x1] Library missing

Application Specific Information:
dyld: launch, loading dependent libraries

Dyld Error Message:

Solution: As suggested in this comment, download and install the Swift 5 runtime library from

Fix confirmed on 10.13 High Sierra. This will almost certainly stop working at some stage, but hopefully by then people will have upgraded…
