My co-admin works with a MAC ( MAC OS Hih Sierra 10.13.6) and I had some probs with his account , but at first I was thinking of some of his mistakes (he is not an expert on portals) ...
Yesterday, however, a constant error occurred: loading a change in the text of a publisher article, this was not loaded! It seemed impossible that this would happen because I could do it correctly (Windows 10).
I asked him to make the same changes with a tablet and a smartphone and the changes were made without problems.
Obviously I started thinking that it could be a problem with the O.S. of his MAC ... but for what reason ??? And why in loading situations?
Then I had an intuition and I made an attempt: I disabled the jGrowl redirect and asked him to repeta tests : his MAC resumed normal functionality. Do you have news of MAC problems with JQuery?
