![]() ![]() Now, in modern macOS when you run out of memory, there are several things that the kernel will do to keep doing its job:ġ. Please bear with me as I will keep using this term for a while. NB: Memory is managed as in pages (1 page typically is 4KB of RAM). I think it's a placebo or short term effect when you see a boost in performance with these cleaners until it fills right back up again.įlush memory = emptying cached pages (files / program etc) I, personally, notice a slowdown whenever the app decides to clear memory and it lags for a few seconds as it does its thing and then goes back to normal. I don't know why CMM would include this, or any other app would, but I guess it appeases those that are in the habit of clearing their memory when they sense a bit of slowdown. Closing it or "cleaning" it with a memory booster is just going to make that space get filled up again with the same thing. So basically the OS is smart enough to use what it needs and if it's using RAM, there's a reason for it. It actually uses more power when using a task manager or memory cleaner because that RAM is going to fill back up again so long as the app is open. I'm not that knowledgeable on the technical aspect of it but from what I have read and understood, the OS is smart enough to manage apps and the RAM it uses so that there aren't any issues with lag and only the ones you're likely to use are given the highest priority. ![]() I'd be really thankful if someone could point me in the right direction to clear this up :-)Īlso, please excuse any misuse of terminology, I'm just an aspiring amateur :-) So I'm wondering, why is it that everybody claims that this should not be necessary/might even be bad for your system? Am I doing something wrong? I would happily follow the advice to not use anything of the sort, but then my personal experience suggests that it's actually very effective. Cleanmymac regularly saved my life by freeing up memory and enabling me to get back to work, at least temporarily. What's more, a few months back I had to edit a video on an old iMac with 8GB of RAM, since my other machine broke. But then, if I perform a memory flush with Cleanmymac ("Free up Memory"), it will return back to its normal speed. ![]() Whenever Cleanmymac shows me there is only a few MB of memory left (Activity Monitor will usually claims that most of the used memory is purgeable) my machine will noticeably slow down. The consensus from people that know more about these things than me seems to be not to use them the OS knows how to take care of itself, there is no need to "remove apps completely", which is what Cleanmymac claims to do, and especially unexperienced users might be lead to delete important files when "cleaning up system junk".Īnother thing that people claim is that memory flushes, where, as far as I understood, Cleanmymac will flush all the available memory and free it up after, are supposedly unnecessary, and undesirable, since the system is very good at managing memory by itself.īut now to my actual question: I have a 2018 MBP with 32GB of RAM, but do a lot of memory heavy work on it (video+image editing, 3D) and every once in a while my memory will max out. I've recently been reading a bit on applications like Cleanmymac and other, more "reputable" applications. Hi, I'm new here so please excuse me if this is the wrong place to ask a question like this! ![]()
