Lightroom 4 crashing and Sonoma
I am using Lightroom 4 and a Mac Pro with Sonoma 14.1.2 . Last March I moved my lightoom catalog and photos to an external drive . Due to death in the family have not opened lightoom or have not download any new photos. I pluged in the hard drive that has lightroom catalog and photos. Next as a test put in my sd card copied two photos on to a folder on the desktop. I then opened lightroom imported the 2 photos. Lightroom crashes when I try to do anything. My guess is Lighroom 4 is not compatable with Sonoma 14.1.2 and wonder if my only option is to upgrade to Lightroom Classis but unsure how to do this and how I would get help
