for about a year or 2 I have been using opera gx on this same Mac computer. today I turned on my computer to see that I can't open gx anymore. when I try opening it, it says that it only works on update 10.15 or later while my computer is 10.13. I would update, but my computer is too old to update any further than 10.13. is there anything I can do to re-open opera? its been working for 2 years now, so why has it stopped working all of a sudden? from what I can guess is that they updated gx so it only works on update 10.15 now. if thats so, is there anything I can do to un-update it?
