LATEST – May 19th, 2025

We’re very pleased to announce that iStudio Publisher v1.7.5 has finally been released in the Mac App Store.

Many thanks to all of you for your patience in this matter. It was really appreciated.
We recognise that many of our users rely on iStudio daily, and it can be very frustrating for all concerned when unanticipated problems like this arise.
The issue was completely out of our control, and the vast majority of our users were both understanding and supportive.

We’re very confident that the mechanisms we’ve put in place should work around the problem with subscription recognition.
Please update and try it out, and let us know how you get on.

Note that running the new version may possibly still initially show an error panel, but you should be able to successfully continue by choosing the option to refresh your store details within the app.

UPDATE – May 16th, 2025

iStudio Publisher 1.7.5 will be submitted to the Mac App Store for review tomorrow.

To anyone who has contacted us, or taken us up on the offer of a free LAC, many thanks for your patience. You will be notified by email once the update is live in the store.

It’s taken much longer than we hoped, mainly because we’ve had to devise our own dealing with the issue. We’ve received no responses at all from Apple, but we’re confident we’ve found ways to work around it.

*** ORIGINAL BUG MESSAGE – April 2025 ***

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.

  2. Click-drag a selection zone with your mouse.

  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.
