Updated OS to catalina and metashape to 1.5.5
crashes when building dense cloud/mesh from depths maps but only on larger files -> i've got it to work on a ~40 photo file, but 300, and 1400 photo files it kills the imac completely - i.e. next time i see it's at the log in screen so I don't have and agisoft crash report, only apple.
it will plod through merrily enough if i turn the GPU off though.
