LATEST LIGHTROOM UPDATE CRASHING MY COMPUTER

I cannot express my anger with Adobe too much.  Since the latest Lightroom Classic update I have been plagued with computer crashes everytime I went into develope mode.  I tried everything, uninstalling reinstalling to no avail.  Eventually I decided to reinstall my operating system but before I did I took one last look at the forums.  There it suggested turning off graphic acceleration and low and behold, problem solved.  More research shows that Lightroom no longer supports my graphics card even though my mac is only 4 years old.  Utterly disgraceful way to treat their customers.  I will be chosing a new photo processing soon and dumping Adobe.
