**Issue**

When downloading a nightly build of GPAC from this link https://gpac.wp.imt.fr/downloads/gpac-nightly-builds/ it states on that very site that the versions for OS X (or macOS how they call it now) are compatible "with 10.7 and above". This no longer seems to be a case. 

Downloading the latest version and installing it on Mac OS X 10.10.5 (Yosemite) results in an application bundle that's blocked out in Finder (with a stop symbol across the icon) and running the contained binaries directly from Terminal results in following issue:

```
$ /Applications/GPAC.app/Contents/MacOS/gpac --help
dyld: Library not loaded: /System/Library/Frameworks/CoreImage.framework/Versions/A/CoreImage
  Referenced from: /Applications/GPAC.app/Contents/MacOS/./lib/libavdevice.58.dylib
  Reason: image not found
Trace/BPT trap: 5
```

With how badly the OS X ecosystem works regarding backwards compatibility you're probably no longer be able to fix the package for older systems (albeit this would be appreciated), so an update of the information of the website seems to be reasonable as a fix.
