Sep 14, 2016 12:10 AM in response to arashsbby John Galt,★HelpfulYou appear to be discussing two separate subjects: storage and RAM. It is normal for all RAM to be used. Please read the Memory section in Use Activity Monitor on your Mac - Apple Support.
Never use "cleaning" utilities for any purpose. Uninstall "CleanMyMac".
It is not reasonable to expect a Mac to operate normally after using CleanMyMac. Like many ill-conceived "cleaning" utilities, it is capable of corrupting a Mac to the point that erasing it completely is the only practicable means of recovery. CleanMyMac is not the only example; it is merely popular due to marketing strategies that are as effective as they are intrusive.
There is no practicable way to reverse the effects of having used CleanMyMac2 other than to reinstall all affected files from backups or their original sources. Its developer's uninstallation instructions are ineffective despite their recent claims to the contrary. Only MacPaw, its developer, can know the reason for that, but I can think of two possibilities: either they are purposefully leaving components behind for reasons known only to them, or they simply don't know what they're doing. Neither one of those possibilities is particularly comforting for the user.
Reinstalling OS X alone will have no effect on either removing CleanMyMac or reversing the damage it is capable of inflicting upon a system.
To recover from the effects of having used it to modify OS X, the additional software you require and the essential files you need, follow the applicable recovery procedure below:
- If you have a backup that you created prior to using CleanMyMac, now is the time to use it. For Time Machine, boot OS X Recovery, and at the Mac OS X Utilities screen, choose Restore from Time Machine Backup. Choose a date preceding the installation of CleanMyMac.
- If you do not have a backup that predates the use of CleanMyMac, create one now. To do that read Use Time Machine to back up or restore your Mac.
- The recovery procedure will require that you erase the Mac using OS X Recovery, and then create a new User Account whose contents will be empty. You will then be able to use Setup Assistant to migrate your essential documents including photos, music, work products and other essential files.
- To erase and install OS X read How to reinstall OS X on your Mac.
- Follow the instructions in that document under Erase your drive and install OS X.
- Then, follow the procedure in Move your content to a new Mac.
- When asked how you want to transfer your information, select Transfer from a Mac, Time Machine backup, or startup disk.
- Under Select the Information to Transfer, select only your previous User account and do not select "Applications", "Computer and Network Settings" or "Other files and folders". De-select those choices.
- Subsequent to using Setup Assistant, you will need to reinstall the essential software you may require, once again remembering to install software only from their original sources, and omitting all non-essential software.
- "Non-essential software" is a broad category that includes but is not limited to third party "cleaning", "maintenance", and "anti-virus" products.

Sep 14, 2016 12:10 AM in response to John Galtby arashsb,thanks for kindly advise, i removed clean my mac.
but my problem is storage that has gone from a few GB free space to zero KB suddenly and i receive full storage error, after 20 second storage return to prior situation.
i check it and understand this problem is caused by RAM but why ?

Storage space is not RAM. If your Mac's internal storage is becoming full please read OS X Mavericks: Increase disk space.

Sep 14, 2016 7:12 AM in response to John Galtby arashsb,i know difference between storage ( harddirive ) and RAM.
storage becoming full suddenly because RAM free space gets too low and after 20 sec everything return to normal situation.
for example :
even if you run out of physical ram, your system doesn't see this and immediately starts using available disk space to handle active tasks.
happens a something like this for 20 sec.

Please refer to the Memory section in Use Activity Monitor on your Mac - Apple Support. Post a screenshot of that Activity Monitor window, similar to the following, with the Memory column sorted in decreasing order.
Then, click the CPU tab, and post another screenshot similar to the following, with the %CPU column sorted in decreasing order.
To learn how to post a screenshot please read the Appendix in Writing an effective Apple Support Communities question.

Sep 14, 2016 8:59 AM in response to arashsbby John Galt,Thanks. Everything was completely normal at the time those screenshots were taken, with an essentially insignificant requirement for either memory compression or virtual memory.
Reproduce the problem, and take the same screenshots again.
