What Happened to my Mac?

Hi, I can see there are a great number of threads on here relating to what could all boil down to the same problem, none of them appear to offer a clear explanation, or better still a resolution. I have a 2011 iMac with 3TB Fusion Drive and all the bells and whistles which I use personally and for business. I run parallels (11) as I develop applications under Linux, and Windows. This was my first Mac and I love it. However, since I upgraded to El Capitan, things have not been so wonderful. My old Windows 7 VM, has become quite slow to respond where once it was lightning fast. My Windows 10 installation, well...I could have written it while it's booting. I don't run more than 1 VM at a time, unless I need to for interoperability, as I tend to stage apps on a laptop that I keep clean for such purposes. I do have clean my mac installed but this is the only one of the trash collectors I have. I don't profess to know a lot about Mac's, although i do understand the underlying architecture having worked with AIX, HP-UX, SPARC and Linux in the past.

I just cannot seem to grasp what could be slowing down this once magnificent beast.

Can anyone help?

Can anyone tell me how I might be able to downgrade back to Yosemite?

Your help would be much appreciated.

"CleanMyMac" is a scam and a common cause of instability and poor performance. Depending on what version you have, the developer's instructions may not completely remove it. Please follow those instructions, then do as below.

Back up all data before proceeding.

Triple-click anywhere in the line below on this page to select it:

/Library/LaunchDaemons/com.macpaw.CleanMyMac2.Agent.plist

Right-click or control-click the highlighted line and select

Services ▹ Reveal in Finder (or just Reveal)

from the contextual menu.* A folder may open with an item selected. If it does, move the selected item to the Trash. You may be prompted for your administrator login password.

Repeat with this line:

/Library/PrivilegedHelperTools/com.macpaw.CleanMyMac2.Agent

Restart the computer and empty the Trash.

You may also have to remove one or more of these items in the same way:

~/Library/LaunchAgents/com.macpaw.CleanMyMac.helperTool.plist

~/Library/LaunchAgents/com.macpaw.CleanMyMac.volumeWatcher.plist

~/Library/LaunchAgents/com.macpaw.CleanMyMac3.Scheduler.plist

Never again install "CleanMyMac" or anything like it.

*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select

Go ▹ Go to Folder...

from the menu bar and paste into the box that opens by pressing command-V. You may not see what you pasted because a line break is included. Press return.

Line is quite right. "Cleanmymac" can be a killer to machine performance.

Hi Thanks, I think I may have to resort to this but will need to make separate back ups of everything I have done since then which is going to be a bit of a bind!
