![]() ![]() (Total physical memory 12 GB.) By your explanation above, I am using 5.61 of memory cache, and effectively using -0.07 GB of memory for everything else. Why do I say that?īecause currently on my iMac I have 5.54 GB used and 5.61 GB cached, and no swap file. So, restart the Mac, and see if there still is an error when logging in under the same user giving you this issue.Click to expand.I'm not sure your description is accurate. In Safe Mode, login items do not open, and damaged files ( caches) are set aside and fixed. One there, log in, wait 30 seconds, open up Activity Monitor, and then see if you still see this issue. ![]() So, try a new user, seeing if you get this error. If not, then it is likely something misconfigured in your current user. If so, then it is likely an issue with the macOS (I which case you'd have to reinstall the macOS). Great job on your part providing feedback!įor troubleshooting purposes, create a new Administrator user, login to it, and see if you get this issue. I have now five URL's open, some of them are consuming close to 1GB, is it normal?, even this page is consuming 0.75GB, is this reasonable that a text page like with a simple form is consuming more than Excel?" " Safari consuming to much memory: Thanks for your response, I just posted a suggestion. It sure would be helpful to have further information on such matters, so we can know better how to interpret these various numbers. (I thought I recalled the Catalina “Virtual Memory Size” equaling the “Memory” column size, but I could be misremembering.) However, this does not mean that this counter has no meaning, because Virtual Memory can include memory within the Virtual Memory space that includes the programming code of the App (this is “swapped” from the App’s files), as well as other, currently unused Virtual Memory space. However, Virtual Memory Size is often much larger than the size shown in the Memory column! In fact, it can be so large that it cannot be physically accounted for even using all Real and “Swap” space, even if one uses a reasonable two to one (2:1) compression ratio for Compressed and Swap spaces! These counters with the same/similar names as the Column names, always seem to agree: Real Memory Size equals Real Memory (RSIZE), Shared Memory Size equals Real Shared Memory (RSHRD), and Private Memory Size equals Real Private Memory (RPRVT). If, in addition to the Memory tab, in Activity Monitor, you Inspect a given process, you’ll find the following Memory related counters, on the inspector’s Memory tab: Real Memory Size, Virtual Memory Size, Shared Memory Size, and Private Memory Size. (It wouldn’t make much sense for it to involve Real Shared Memory.) Purgeable Memory always seemed to be a portion of Real Private Memory (RPRVT). On Catalina, it always seemed (but I could have simply missed cases where this wasn’t true) that Memory minus VM Compressed yielded Real Memory (RSIZE), which, in turn, equaled Real Private Memory (RPRVT) plus Real Shared Memory (RSHRD). I run with the following memory related columns viewable: Memory, VM Compressed (Compressed Memory), Real Memory (RSIZE), Real Private Memory (RPRVT), Real Shared Memory (RSHRD), and Purgeable Memory. I don’t still have a Catalina system on which to test, but, as I recall, the values on Catalina seemed to “add up” better, there.
