Have just updated to Mountain Lion, and it initially refused to run the latest beta of DataGraph as it comes from an "unidentified developer".

That can be permanently circumvented (at least for the current beta) by right-clicking on the DataGraph icon and choosing "Open", but most users might not know that.

I guess the App Store version has to be signed, but does the beta slip through without that step?

Here is the strange thing. I have that setting on my machine and it doesn't complain. I tried it on a different machine and the same download caused problems.

I do code sign, using my developer key, but I am compiling the version on 10.6 with support for 10.5. I will look into forking the release for 10.5 and 10.6 and compile the 10.6 version on a 10.8 machine.

That's true, and only because Safari sets the download attribute.

But I download this myself using Safari and mount the disk image. It tells me that this application is downloaded from the internet, but it doesn't stop the execution.

There are several possible reasons, but the frustrating thing is that I can't replicate it on my machine. It is there because I've seen it happen. What also seems to be the case is that it doesn't happen for every beta. But it should be identical, since I use a shell script to compile and upload the beta version.

The workaround is to control-click and launch it that way. That sets the flag to "safe" and the application will be OK after that. But I definitely have to find out why it happens.

Have just downloaded the latest beta. Now I don't get any warning dialog at all: double-clicking just launches the programme immediately.

I don't know Mountain Lion well enough to know if that is normal behaviour or not for a signed application. (Under Lion, I got a warning dialog with every first launch of a newly downloaded beta).

Good to know. I did tweak things a little bit, but it might also have been something else altogether. So this might come up again, so let me know whenever you can't open the app or something changes.
