Halliday,
Why I say that it is because it is because Big Sur is running out of memory is because I have been monitoring the use of memory via Activity Monitor. What I have discovered that the Apple News app keeps taking up more and more memory over time. I don't think that that in itself should cause Big Sur to freeze because it should draw on virtual memory. However, the amount of virtual memory that is used seems to very very small. If I keep on closing down Apple News and re-opening it, then this doesn't happen. I haven't observed any other applications doing this but then I don't use a lot of different applications. …
When you say «the Apple News app keeps taking up more and more memory over time», are you referring to the use of your system RAM, or the amount of “Memory” that Activity Monitor claims «the Apple News app» is using?
What does Activity Monitor report if you bring up the App Information window, for «the Apple News app», and look at how much Memory is reported for each of its memory categories, such as Virtual Memory.
Along with this, how much Swap memory does Activity Monitor report as being used, for everything being run on your system?
What does the Memory Pressure graph show?
What color is the Memory Pressure graph?
How close to the top (100%) is the Memory Pressure graph?
(These two indicators do not track one-to-one.)
When I say that the system "locks up", this isn' entirely true. What seems to happen is that it becomes extremely slow. By this I mean that it may take 5-10 minutes to do anything. When people talk about the use of virtual memory slowing down the OS I don't think that they mean to this extent. I interpret this observation to mean that the amount of used memory of any type that is available to the OS has become extremely limited but that what little remains is used to do what can be done in whatever time it takes. …
What sort of drive are you running your macOS from? A Hard Disk Drive (HDD, spinning disk)? Fusion drive (a little better, but, often, not by much)? A Solid-State Drive (SSD)?
Swapping will, typically, slow a HDD or a Fusion drive, quite a bit.
An SSD will show much less slowing.
This behaviour only started when I upgraded from Catalina to Big Sur some time ago. I never had the issue under Catalina. My pattern of use hasn't changed to any significant extent. …
I actually had slower performance, and far more issues with running out of memory (and High Memory Pressure, often running in the Red), running under Catalina, up until the last Catalina update just before Big Sur came out.
I have had no issues under Big Sur more than what I had under Catalina just before the upgrade to Big Sur.
(Note, however, that I made certain not to upgrade to Big Sur with any incompatible software.)
If I can throw the question back to you, why do you claim, without any evidence, that the problem I'm reporting is "not "through running out of memory?"" I know that other things can often cause such problems but the fact that they CAN cause such problems doesn't mean that they ARE the cause of the problems. You are making that claim without a shred of evidence.
Not only have I had no such troubles with Big Sur, on my 8 GB RAM Intel Mac mini (minimal configuration); I have helped many others clean up their incompatible software (inherited from Catalina), to find that their systems run at least as well under Big Sur as they used to under Catalina.
(Admittedly, not everyone with such issues have been willing to work through cleaning up their systems.)
