I have a mac mini with 8 gbytes of RAM. When my wife and I are both logged in (but only one actively, of course),
the memory usage goes up to maximum (7.94gbytes). Of this, only 2.8gbytes are app memory, with 4 gbytes of file cache.
This seems ridiculously high. Is there a way for me to instruct the mac os to use less file cache?

In activity monitor it shows that I have 16GB of physical memory, 12.77 GB used memory, 16GB virtual memory.
It also shows App memory 1.9GB, FILE CACHE 9.56GB and wired memory 1.31GB.
My question is in regards to file cache at 9.56GB. What is file cache and why is it so high? Does this mean I should install more memory? I looked file cache up and I think it's memory that has been used but is not being used currently, it's waiting to be used again. Not sure if that's right though, or what it really means.

Out of the blue my Mac suddenly is devoting a huge amount of ram to file cache. I have 32 Gigs of Ram and curretly 27 gigs of that is devoted to file cache. I am only running mail, iTunes and Chrome and I have 7 mg of ram left. What could be causing this and is there a fix?

I used Onyx to clear my system cache and user cache. When it was done, my iDisk icon was changed, any way I can restore this? The problem is that he saved this one as the original icon, so I can't delete it from the "get info" window.

My iMac 24 has been acting just a tiny bit sluggish of late, seeing the pinwheel a few times. All the reading I've gone through suggests two possibilities; overloaded cache or a HDD that's starting to go south. Hmmmm. OK, so exactly how do I get to the so-called "Library Caches" and which folders do I delete. Next, is there a good diagnostic tool that will give me layman's language results that a consumer/user can understand? And lastly, if the HDD is going south and my iMac is long past warranty... can I; (A) replace the HDD myself, and (B) can I upgrade the drive size (currently 500G) to a 1TB drive? My machine currently has 4 Gigs of RAM and I guess that's all it can handle right? Wish I could upgrade that!
I did clear my safari cache and saw a decent pickup in speed.

Recently I Apple and a technician helped me clear my "cache" (I am obviously a former PC user). I cannot remember the steps we took and she said it is a good idea to do this periodically.

I need to populate the bays of my new MacPro 2.66 with 5GB RAM. The stock HD turns out to be a Seagate 250GB HD ST3250820A. I've found them online and wonder if I just should RAID three or four of them as opposed to one Seagate 500GBs or 750 with 32GB cache? These would all be a Raid run by Apple software not a RAID card.

Some of my automatic logins that the mac remembers are incorrect and my issue is that when updated, are somehow not retained in the autologin. This means the feature is often useless and causes ultra frustration as I rely on it heavily.
How do I reset the disfunctional logins, or will I have to clear them all and start over, gah? It does not happen on all of them

I understand why "Open With" includes both old and new versions of updated apps. Fine. But how do I CLEAR the list and prevent this from continuing? (I'd expect it to offer a "Clear List" option at the bottom. It doesn't.)

Which one of these 500gb drives is better? I've been browsing Newegg for two hours now reading reviews. The Seagate drives seem to come with bad firmware that causes performance and cache recognition issues. The Samsung drives have a high failure rate. Whats the real deal? Has anyone here had any bad experiences with either drives?

My activity monitor says I'm suing 122.43 GB of virtual memory. I'm sure that the number is much, much less. But I would still like to reset the virtual memory.
Are there any terminal commands to rest the vm?

I have a Mac Air running Mavericks on a HFS partition and Windows 7 on a BOOTCAMP NTFS partition. I have some files that I want to read/write from/to both systems. Since OS X can't write NTFS and Windows can't write HFS either, and I don't want to use any 3rd-party tools/drivers, in OS X, I copy those files from NTFS to its HFS partition, make changes, then switch to Windows and sync them back to NTFS.
The problem is, after I copied a file from NTFS to HFS in OS X, it seemed ok. But when I switched to Windows, the very copied file in HFS partition had its size changed (bigger) although I didn't make any changes to it in OS X yet. This happens to almost every file I copied, text and binary. For those text files, I tried to open it with EditPlus in Windows and EditPlus reports the correct size on the status bar.

I would like to direct my Documents, Pictures, and "Other" to 3 folders in my downloads folder upon downloading them, either with Safari, with Finder, Folder Actions, Automator, or with any other free tool that does not take up too much CPU load.

I want a game to play my favorite song when the game is supposed to be playing its own theme song. The theme song is in a sound file that is located on my computer's hard drive. The theme song sound file is in the same format as the sound file that contains my favorite song, so I don't need to convert any files. What is the easiest way to make the game think that the sound file I want the game to use is the sound file of the theme song?

I am using osX 10.9.4 on an iMac. I am unable to unzip files with either the Archive Utility or The Unarchiver. When I follow the instructions, I merely get another zipped file: .zip.cpgz. (These are files downloaded from the soon to be defunct [UR].)

I have some movies on MKV files that work on a MKV program that I have but every time I open the file it opens a file file converter program that I have. Is there a way to make it so all of the mkv files open in the mkv program without left clicking on each one and setting it to open in the MKV program each time?
