Hello Apple community

 

I own a Macbook Pro 13'' Late 2011, 4 or 5 months ago I installed Windows 7 on it via Bootcamp. Since that day I noticed that it doesnt run as smooth as before, I got some weird "lag" and it doesnt feel so good as before. It takes alot more time to boot and alot of times applications look like they are not responding (like on Windows ) and I've to wait some seconds till it starts running again.

 

I also noticed that on Activity Monitor -> System Memory I got really low Free Memory but the Process's have really low %CPU so I dont get what is causing this :/

 

 

Is there something I can do to solve this? Removing the Bootcamp would solve it?

 

Thank you for your patience, hope you can help.

MacBook Pro, Mac OS X (10.7.5), Performance

    You don't have sufficient memory installed for the number of concurrently running applications and/or you don't have enough free space on the HDD and/or you need to reinstall Lion.

     

    Reinstalling Lion/Mountain Lion Without Erasing the Drive

     

    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.

     

    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.

     

    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.

     

    Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.

     

    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
