Your latest update is one of the worst yet. A couple of weeks ago, your financial tools were really working great on all my Mac computers. Now your software will not run on my oldest iMac (OS 10.13.6), and it runs slower on my newest iMac 2020 with i9 processor. This is not the first time that your software modifications have caused problems on my computers. Perhaps you might consider adding a bit more horsepower to your coding team.
