RAM memory filling up soon on my iMAC, after upgrading to OS X 10.9 Mavericks..

I have had similar issues with mavericks using my memory. I have a 2012 macbook pro. I use memory clean to monitor my memory. I had an avg. of 2g available with normal light use (safari, mail, iTunes) after time the memory would deplete. I upgraded my memory to 8g. My avg. became closer to 4g but would still go down to 1g and some change regardless. From what I'm reading, Mavericks utilizes your ram to the best of its ability. So, with 4 gig it caches as much ram as it can to make programs available and with 8 gigs it does the same but now can cache even more ram thus making the applications more efficient. My question is this: is mavericks supposed to take back ram from the applications it is super-caching when other programs open (like iphoto, or imovie), or will I have to keep using memory clean to take back the ram so I can open larger programs and let mavericks cache the heck out of the desired application?

I've not checked that specifically, but also do not have any problems running iMovie, FCE, iDVD, or Photo to Movie (in place of iPhoto which I don't use). This is with 8 GB RAM on a mid 2012 MBP with Mavericks. Yes, the usage shows higher than with previous OS versions, but as long as the memory pressure shows green and you're not getting beachballs, etc., things are working as intended.

I would uninstall memory clean. Do a search on these forums for it and read a bit.

Mavericks has eaten all my RAM :-(

I have 12gb of RAM for light business use and it's down to a few mb within half an hour. If I had 10gb of Ram I'd be toast.

I'm constantly clicking to clean my memory thorugh the Memory Clean app I just don't know what I'd so without but it's really getting on my nerves and is slowing me down.

Very unhappy.

File cache seems to be the culprin.

How can we stop it?

Please post a screenshot of your memory usage bar (at the bottom of the window) in Activity Monitor. Mavericks is designed to use all the memory - idle memory is not productive. If it is green or yellow, it is fine.

I have the same problem with my Brand New Mac Pro. right now I have 22GB of "File Cashe" and all of my apps are freezing from a lack of RAM

I'm in the samer boat as DavidJames1000 except I started out with 32 GB of RAM

For a new Mac, contact Apple's Support, formerly Apple Express Lane and let them deal with the problem.

Here you are Babowa.

The Mac has only been on for 30 minutes and all I have open is Safari, Mail, Pages, Activity Monitor. Now down to 2.28gb already.

Get this sorted Apple. Using RAM is right not not right when we buy it to stop or apps chocking and our Macs seizing which is what ours are now doing since Mavericks.

For what I've gained I actually wish I'd never upgraded to Mavericks. it *****.

Please fix this Apple or it will be time to start posting YouTube videos about the problem.

Then, revert to your Mtn Lion bootable backup/clone or TM backup. The new memory management is designed to use all. I've not experienced any apps asking for more RAM.

Mavericks is killing me. It tremendously slows slows down when using any RAM-eating applications, like iTunes, Garage Band, iMovie, etc., heaven forbid trying --- yes trying --- to stream Netflix, or any other HD video streaming websites.

Oh, and don't even think about trying to use Chromecast and bounce anything from Chrome to your TV.

It's a brilliant business stragedy if you think about it... Apple tricks all their uses to upgrade to their new OS X, which then forces everyone to go to the Apple store and spend $200 on more RAM.
