I have recently upgraded to Labview 2018 on Mac OS X Mojave, and I have strange behaviour that I am not sure whether is a bug or a feature. What happens is that several menu items in the 'Edit' menu disappear at times. Specifically, the "Browse Relationships" item is missing. See attached screen shot. Is this something that can be turned on and off (I am not aware that I am doing anything to cause it), or is this a bug?
Was this menu item appearing as you expected before you updated to Mojave? Also, you said that it happens at times in your post above. Is this something that only happens sporadically?
Well, I upgraded to Labview 2018 and Mojave at the same time, so that was not a well-designed experiment. My previous installation was a couple of versions out of date for both the OS and LV. Yes, LV runs for a while as expected and then the menu disappears. Otherwise everything seems to run more or less OK, although it seems more prone to serial-port-related crashes than the last setup. However serial port problems seem to be a bit of an issue with the Mac overall.
I personally have never experienced anything like that. I wonder if any one else has, or if it's an isolated event.
