Autocad 2018 for Mac crashes and freezes my Macbook

[Anonymous]

Since updating the operating system to Mojave 10.14.6, my Macbook has started crashing when Autocad is in use. I have Kernel panics and my Macbook Air freezes, which often causes the need to restart my Mac with the power button. It can happen randomly, like when I move something in the drawing or when I cut some lines. I tried to use the command "RECOVER" and others like "PURGE", but it seems to be useless.
My computer, as I've written before, is a Macbook Air 2017 Mojave 10.14.6 with a processor 1.8 GHz Intel Core i5 and memory 8 GB 1600 MHz DDR3. I'm using Autocad 2018.

Welcome to Autodesk Forums!

Hi Francesca,

Have you installed the latest Update for AutoCAD 2018 for Mac from >>>>here<<<<?

Yes, when I check for updates, it says that my version is up-to-date.

Click menu AutoCAD 2018, select About AutoCAD.
Do you see: Product Version "AutoCAD 2018.3"?

It is.

How complex are your drawings?
Do you have enough free space on your Mac disk?

The one I'm working on right now is 308 KB, but Autocad freezes and forces me to reboot my mac with every drawing. I'll send to you the file that makes it freeze the most, which is the 308 KB I was talking about.

I have more than 40 GB free on my mac at the moment, are they enough or do I need to free some space?

[maxim_k]

40 GB seems enough, and what is the total disk capacity?
Can you attach one of your drawings here?
Or you can send it to my e-mail [email protected]

This is the file I'm working on right now. I tried to use RECOVER on it but after taking care of its problems, it just freezed again. 

The total disk capacity is 120 GB

I see you have PDF underlay attached to your drawing, but you haven't attached it.
Do you use that PDF when editing the drawing?

Yes, I use it but it’s never been a problem. Also, Autocad doesn’t work properly even with files that are less complex.

If you have PDF underlays attached to all of your drawings and use them for tracing, you can try to convert them all to JPG raster format and attach JPG instead of PDF.
I noticed that PDF underlays could impact AutoCAD performance and maybe can case AutoCAD hangs on your Mac.

I’ll try, thank you!
