Good Morning, John. I believe I have encountered a major issue with MC 19 for Mac and Mavericks. MC has been running well and sounding excellent until the upgrade from Mountain Lion to Mavericks. The problem begin after about an hour listening session where MC completely shutdown. The OS continued to function normally, however. An error window appeared with a slew of lines of code detailing issues. JRiver is listed along with many other items such as Apple Core foundations, if that is important. MC will start now but upon selecting a tune the program crashes with yet another error window.
I am sorry to say I don't know how to send these error messages as I am new to the Mac platform. Apparently no copying and pasting in an email for example. There were no changes to anything such as hardware or software setup. Just the update to Mavericks. Not much to go on but obviously something happened in the update to render MC useless at this point. I did install the latest update for MC before upgrading to Mavericks and am using a current iMac that was funning Mountain Lion. I also noted a shift in the playback where tunes seemed to be darker and slightly less detailed on top. There were also some distortions noted at times not experience before.
Will let the experts at JRiver sort things out. Thanks in advance, though
