[M1] "System is running out of memory" error is thrown when using Profiler as a Standalone Process with Deep Profile turned on

MacOS

-

How to reproduce:
1. Open the user attached "URP_BasicDecalExample.zip" project
2. Enter Play mode
3. Open the Profiler as a Standalone Process (Window -> Analysis -> Profiler(Standalone Process))
4. Turn on the Deep Profile setting in the Profiler
5. Open the Console

Expected result: No errors
Actual result: A "System is running out of memory" warning and error is thrown

Reproducible with: 2020.1.0b14, 2020.3.25f1, 2021.2.7f1, 2022.1.0b2
Not reproducible: 2019.4.34f1, 2020.1.0b13

Note:
- Reproduction is somewhat inconsistent, multiple tries might be required
- Only reproducible on M1
- The issue is also reproducible when baking the scene
- The reproduction consistency is dependent on RAM

    This is marked as fixed in 2021.2.13f1 but is still happening when building our game and sometimes while importing. Just on Mac M1.

    I have encountered the same issue on version 2020.3.26f1. I’m using URP inside an AR app on my 8GB 2017 IMac with no other applications running so I doubt I am truly running out of memory. Do you guys have any timetable for this 2020.3.26f1 fix?

    Excuse me for yet another message related to this, but it might be useful.
    It might really be that the system is running out of memory or at least it is being detected as such even if the Unity's reported log says 10% or 20% usage only.

    I have found, on my side, another machine, M1 Pro 16GB of RAM, that the profiler seems to work if I close most utility apps(*) that are usually opened
    It seems like if on Activity Monitor the memory pressure is on yellow, then the profiler will discard the frames, if it shows green it will work.

    This way I have had the profiler work on both 2021.1.28f1, 2021.2.9f1

    ---
    (*) Utility apps usually are: Teams, Discord, Slack, Outlook (web based), Figma, Notion, etc. The chatting apps themselves can gather up to 2-3GB of RAM (yeah, I know, full blown games need less than that), Outlook on it's own another 1 or 2GB depending on some context that I can't pin point, etc for a whopping 6GB not counting the rest of the system.

    Would be very curious to know if this is being worked on or backported from potential future versions that already work (if any)?
    Just tried the latest version to date, 2021.2.9f1 that came out what seems this week and the issue still persists.

    Would be also good to know if it is actually a reliable message (memory system is filled for profiling) or it is a bug since it says things like only 15% is in use yet there's not enough for profiling.

    If anyone with a 32GB system could chime in would be greatly appreciated.

    Thanks a lot in advance.

    This same error happens when baking lighting in big scenes with GPU

    Yeah, it's 2020.3.x of course, thanks for the notice.

    To further expand, on a higher spec'ed system. Same behavior, just a lower "% usage% reported (less than 20%).
    MacBook Air 16GB, 1TB SSD (just 100GB used).

    On Unity 2021.1.28f1 and 2021.2.7f1 (Apple Silicon version) the error triggers.

    Regarding the original commenter, 2021.3.X, is that a typo relating to 2020.3.x instead?

    Another data point if it helps, Unity 2021.1.28f1, MacBook Air M1 (8GB... will be trying in a 16GB one very soon).
    Difference is normal profiler (non-standalone) and no need to do a deep profiling, the shallow one also makes it happen.

    Error log reads as follows:
    Used memory (physical and paged): 46% (7138MB of 15360MB). Discarding profiler frames data.
