This bulletin relates to the Mac App Store version 1.7.4 of iStudio Publisher.

We are aware that a number of users have been experiencing connection problems with the Mac App Store since upgrading to macOS 15.4

Apple appear to have broken something with the release of macOS 15.4, causing iStudio Publisher to be unable to retrieve purchase information from the store when it starts up. This results in users affected by the problem being unable to save or print.

Please bear with us while we try to find a solution to this issue.

If you are desperate and have a deadline, contact us at the usual support email address (see below) and we will send you a free License Activation Code for the web store version of iStudio Publisher.

Up-to-date information will be posted on our Twitter/X page as it unfolds. Many thanks for your patience.


IMPORTANT: Before sending a support request, please check that iStudio Publisher is updated to the latest version and take a look at the Frequently Asked Questions and help pages to see if your question is answered there.

Reporting a Problem

If you are experiencing a problem please send us a screenshot of any related error message. Also, choose menu option  > About This Mac and send us a screenshot of this dialog box.

TIP: You can take a screenshot by using the standard Mac screen capture facility, as follows:

  1. Press key combination Shift-Command-4 (press all three keys together) to change the mouse icon to a cross-hair.
  2. Click-drag a selection zone with your mouse.
  3. Release the mouse to take the screen shot – you should hear a camera shutter sound.
  4. The screenshot image will be captured as a .png image file with a default name and placed on your Desktop.

Installation and Licensing Issues

App Store Edition

The App Store Edition of iStudio Publisher (purchased from the Mac App Store) includes Apple’s own digital rights management system and once installed it should work immediately. If iStudio Publisher is asking for a License Activation Code this is the Website Download Edition, and you will need to install the App Store Edition instead, as described here.

Website Download Edition

If you have the Website Download Edition of iStudio Publisher and are contacting us about a licensing related issue please choose menu option Help > Licensing > Check License and let us know your iStudio ID – you can copy and paste this from the dialog box.
