I just restarted my Late 2011 Macbook Pro. 3.58Gb-3.71Gb / 4.00GB are being use right out the gate. It takes forever for anything to load. I'm very interested in purchasing new ram, but for the time being I'm hitting the ceiling and it's not necessary. Anyone have any recommendations as to why I'm maxing out, and what the hell is kernel_task doing? I'd love to just reinstall the OS from scratch.

Mavericks has a sophisticated RAM management software.

The good old days where you did the job of trying to keep as much RAM free as you could are obsoleted. Someone had the good idea of what is the purpose of RAM that is not used.

So use it all or as much as you can and manage the dynamics so it does not overun to Swap.

What it means it will continuously optimize the RAM usage while prioritizing the accessibility the speed to which applications open.

It uses a feature called Compressed memory to gain RAM space.

The measure of its success is not to have swap (if possible), which is using the hard disk as RAM, that slows it down.

In your case there is no swap or compression so the slow down you are experiencing is not your RAM.

Also looking at your memory pressure it is in normal levels.

You have 8 Google windows open totaling in 250 MB of RAM (that is also normal), but that could lead to slow down opening all of them at once.

To find out what is slowing it down you need to look in the console and publish some lines here at the time stamp of opening a application that takes long time to load.

As for kernel, it is normal for it to use up to 500 MB of RAM for all its jobs it has to do.

  • Thank you very much for this explanation. I'm experiencing delayed typing and very slow responsiveness when I finally get in my zone and I have all of my development applications and tasks running. It's super frustrating, I'd love any way to rectify it. What's the console command? – ThomasReggi Apr 14 '14 at 14:40
  • Console is a Application in your Utility folder. It is a text file that collects system events. So Open it and look at the time stamp when you have the slow down. You can copy and publish here but in a NEW question please. We might be able to help you to find out what is slowing down your computer. – Ruskes Apr 14 '14 at 15:04
  • Oh I confused "Console" for Terminal. I just opened it up, this is very helpful. – ThomasReggi Apr 14 '14 at 19:22
