Q: my computer starts very strongly hot

When did this start, Tatiana?  After upgrading to Mavericks? After you imported new images? Installed any new software?

Try to narrow down the problem. Is the performance better, when you hold down the Shft-key while launching Aperture?

Do you have the same problem, when you test with a different Aperture library? Create a new library with just a few images for testing.

Tatiana,

Wha is your Aperture version number?

How much memory (RAM) does your iMac have? My Aperture works better with Mavericks after upgrading to 16 GB, but that should really not be necessary.

When processing images in format Rav program stops work well and my Computer is becoming a very hot ( as the program takes all the memory is . You have to complete all programs including Safari .

Are you also closing Mail? When I had a similar problem, I discovered that Spotlight and Mail caused the Mac to hang after the Mavericks upgrade, not Aperture. Try to delete Mail, you no longer need, rebuild your Mailboxes  (Mail > MAilboxes > Rebuild), and to rebuild the Spotlight index. See:  Spotlight: How to re-index folders or volumes

To check, which application is causing problems, look at the Console Window and the Activity Monitor.  Both applications are in the folder Applications > Utilities.

Make sure, there is no problem with your Aperture library or settings in your user account: Try these steps:  Aperture 3: Troubleshooting Basics

Also, if you have any older applications installed or Aperture plug-ins, check there compatiblity with MacOS X 10.9.1 and update or uninstall them, if necessary.

Unfortunately, there may really be a problem with Aperture 3.5.1 on Mavericks and certain Mac models, see these threads:

Is there a memory leak in Aperture 3.5?

memory leak

Then nothing will help, but waiting for a bug fix to be released by Apple.

So I disabled the Onscreen Proofing like it became better memory goes , but not so fast stopped at 1.6GB free 's capacity , you can still work like that , and my computer does not so hot.

Your memory usage looks perfect now with 1.6 GB free.

If the memory would not be used, it would be wasted.

This green bar shows, that the mac does not have a memory problem - the memory pressure is low.

Noticed that the memory starts to leave when working with curves and using brushes.

Curves and brushes need really much memory to store the masks, so that is natural and to be expected. Does the memory used drop again, when you stop brushing and close Aperture, or is the memory not released?

Working with other settings, memory stop goes, that is fine, but as soon as I start to apply presets, work with curves and with tassels, memory goes.

I am quite sure, there will be an update soon.

Please tell me where to find my own presets that I created myself , I want to copy and save just in case

Your own Aperture presets are in your User Library:

~/Library/Application Support/Aperture/

You user library may still be hidden, as is the default:

• Quit GarageBand .
• Select the "Home" folder icon (the little house)  in the Finder's sidebar and press the key combination ⌘J to open the "view options". Enable "Show Library Folder".
• 

Then open the Home folder and open the Library folder inside and navigate to

~/LibraryApplication Support/Aperture/

But if I have any more questions or concerns, I can you turn for help?

Sure Tatiana, my pleasure. добро пожаловать
