simulation - LTSpice IV for OS X (oct 2, 2018 version) crashes on macOS Mojave 10.14


I downloaded the latest LTSpice IV for mac OS, I'm running mojave on a MBP. It is crashing in my setup, apparently as soon as it opens the plot window. The simulation starts running, but when it's ready to plot and opens the plot window, crashes.


EDIT >>> This happens regardless of the model simulated, existing or new, even a simple AC source makes it crash.


Is anyone else experimenting this issue?


The error report says (I paste what I think is relevant):

PS: Yes, finally Analog has released an LTSpice IV version for mac. The download page says 2016 but actually it's a release from 2018. See this question. How do I update LTspice IV for macOS? Among other things it fixes the "xx days old, please update" problem.



Answer



I had the same error and I emailed Mike yesterday and he replied saying there are many problem with Mojave and he fixed the major bug about macOS mojave. I updated my LTspice and it is working fine now. Maybe you want to try to update using "operations" and choose "software update". Hope that will solve your problem.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
