[Solved] OSX "unidentified developer" warning


This question is about the “pro” version.

The screensavers we have created with iScreensaver are beautiful - thank you!

We have a bump on running the resulting installer on OS X v. 10.8 and higher. If someone double-clicks on the installer, they are blocked, with a message saying the executable is from an “unidentified developer”. Instead, the user must change their preferences in Gatekeeper, or control-click to open and run that way.

Basically it’s the situation described here:


Does iScreensaver Pro have any way to work around this? What we’d like is to let the installer run just by double-clicking on it, since that will be a simpler user experience. We are willing to get a developer account with Apple.


Unfortunately there’s no easy solution for this, so there’s no way it will be fixed in two weeks.

iScreensaver 4 was released prior to the new OS X “Gatekeeper” functions. Although iScreensaver software has a valid code signature, Apple doesn’t recognize it for some technical reasons.

We hope to address this issue in the near future.

In the mean time, the workaround is very simple:

Instead of double-clicking the screensaver installer, do this:

  • Hold down the control key and click the installer
  • From the popup menu, choose “Open”

I see. Thank you for the very prompt reply.



Is it possible you can expedite this, and get the issue addressed in the next week or two? We bought iScreensaver to make a screensaver as a Christmas gift for our (international) group, and plan to distribute it on or about the 22nd. Overall we are extremely happy with the quality of iScreensaver; we’d also like to have this handled, as many of those we made it for are not very computer literate, to the point where they might have some trouble even with this, or get scared by the warning message. We’d like to make the install an easy and fun experience for them too.


hello there!

is there a solution for this already? the ‘near future’ is pretty much here! :smiley:

i bought iScreensaver and created a screensaver for a client.
they got back to me and asked if i can remove the ‘unidentified developer’ popup, because it would be a hindrance for their users.

i guess they don’t explain to them how to disable gatekeeper functionality in OS X. :slight_smile:

please, iScreensaver, fix this!
otherwise, everything works great for me.

Hello there,

Unfortunately the fix we had planned to implement would not work with the changes that Apple made with their 10.9.5 update in late 2014. We have come up with a new solution which will be available in our version 5 release of iScreensaver Designer.

We understand this is a big issue and are working our best to get it solved, and we appreciate your patience.

Hi there,

I just want to add that this is a very much needed fix. I am evaluating iScreenSaver Designer 4. This problem would be a show-stopper for us because distributing a screensaver that shows warning to customers makes us look unprofessional.

Any timeline when version 5 would be release?
