Unity says: "The System is Running out of memory." when it is not.

Question

The following error message displays in the Unity Console when I exceed 60% in memory usage:

 The system is running out of memory. Please close applications to free memory or free up space on the partition where the pagefile is located.
 Used memory (physical and paged): 64% (6634MB of 10240MB).
 Discarding profiler frames data.

I have sufficient hard disk space available for swap, but no new swap files are created because the system does not have the need to. The problem started after upgrading to Unity 2019.3.11f1 from 2019.3.6f1 I'm working with the Universal Render Pipeline. The extreme cases the editor completely hangs during some sort of file processing operation and I have to kill and restart it. It has gotten so bad that I cannot run my browser, IDE and Unity all at the same time. My specs are below: Macbook pro 13" ,Core i5, 2.8 Ghz, 8GB Ram, 256GB SSD

Nope, Nothing yet. I was able to get rid of it with 2019.4, Not sure exactly what I did there, but It's back with 2020. I've created extra space on my drive & reset PRA$$anonymous$$.

Same issue here with Unity 2019.3.12f1. It's weird because it is a very small scene. Also using URP and with only 1 Monobehaviour attached to a GameObject and one custom unlit shader made in shader graph. It must be project-related because my larger projects run without issues. I just don't understand what could possibly cause this since the Monobehaviour is a simple movement script. Specs: MSI GE75 Raider: Core i7-10750H 2.6GHz, 16GB Ram, at least 200GB free space on the system and install drivers.

"The system is running out of memory. Please close applications to free memory or free up space on the partition where the pagefile is located. Used memory (physical and paged): 22% (2328MB of 10240MB)."

22%.. okay Unity.

In case of M1 chips, this is now tracked as issue 1386242.

As for other hardware, if your system monitor displays a total memory usage across the system that would suggest that there should still be enough space, please file a bug report so that we can fix that too.
