Does anyone have experience with Ccleaner for Mac or Clean my Mac

Yup!

Heard of these.

DO NOT USE ANY OF 'EM!!!!

Apps like MacKeeper or any other maintenance apps like CleanMyMac 1 or 2, Dr. Clean, TuneUpMyMac, Mac Optimise, MacCleanse, Memory Clean, App Cleaner/Zapper, etc. or anything like these apps, installed on your Mac, while they appear to be helpful, can do too good a job of data "cleanup" causing the potential to do serious data corruption or data deletion and render a perfectly running OS completely dead and useless leaving you with a frozen, non-functional Mac.

Plus, these type of apps aren't really necessary.

They really aren't.

The are manual methods to clear off unnecessary data off of your Mac that are safer and you have complete control over your Mac and not just leave a piece of auto cleaning software in charge of clearing off data off of your Mac.

Their potential of causing OS X issues outweighs the implied good and benefits these types of hard drive or memory "cleaning" apps are written to do.

These types of "cleaning" Applications are useless and really scams to rob newbie and novice Mac users of their hard earned cash for a poorly coded/developed application that will cause a LOT more harm than the good the developer of these apps claim/portends the apps will do.

Plus, the software companies that write these apps make it hard to easily uninstall these apps if something DOES go wrong and these apps work in a way where you have no recovery or revert function to return your Mac back to its former, working state in the event something does go wrong.

It is best to never, EVER download and install these types of apps.

The risk to your system and data is too great a risk!

Such products are not required, and in most cases will do far more harm than good. To evaluate what may be causing slowness, please download and run Etrecheck. After running, copy and paste the report into a reply here. Please see the articlebelow for more info.

Using EtreCheck

In addition to the Etrecheck report, here are some other things you can do to clean up your iMac's hard drive.

Here are some general tips to keep your Mac's hard drive trim and slim as possible

You should never, EVER let a computer hard drive get completely full, EVER!

With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.

If it does, it's time for some serious hard drive housecleaning.

Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.

Have you emptied your Mac's Trash icon in the Dock?

If you still use iPhoto or Aperture, both have its own trash that needs to be emptied, also.

I don't use the new Photos App, so check to see if there is a trash icon or trash inside of the Photos App that you may need to empty,

If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.

If you are an iMovie/ Final Cut user, both apps have their own individual Trash location that needs to be emptied, too!

If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!

Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.

Look through your other Mailboxes and other Mail categories to see If there is other mail you can archive and/or delete.

STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!

Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.

Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.

Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.

To find other large files, download an app called Omni Disk Sweeper.

Also, Find Any File

If you are using OS X Time Machine for backups, make sure these backups are being stored to an externally connected hard drive for backing up data and NOT being stored on the iMac's internal hard drive.

Typically, iTunes and iPhoto/Photos app/Aperture libraries are the biggest users of HD space.

move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.

If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.

A disclaimer,

Things to consider before moving your iPhoto/Photos Library Folder to a new or external location like an external hard drive.

If you make movies on any iDevices using iMovie for iOS,, then transfer the video footage, the IOS version of iMovie saves the footage as a movie file in IPhoto/Photos for IOS and will automatically get transferred to iPhoto/Photos for the Mac when you upload the video from your iDevice.

Newer versions of iMovie will work and link those video files found in your iPhoto/Photos Library on your Mac, but those links can be lost if you move your iPhoto/Photos library and you will not be able to relink that video afterwards as the current versions of iMovie seem to not have a relink option for the video portion of the files (ironically, current versions of iMovie HAVE the ability to re-link the audio files from the video footage, though (The inability to re-link the video files could be a possible bug or oversight in current versions iMovie).

The lost video links show up as "blacked-out" video blocks with no content.

Before moving the iPhoto/Photos Library

If you make movies with iMovie using iPad or iPhone video then 'Consolidate' the files before you finish. This will gather (albeit by duplicating) all the relevant files in the project in one place. After consolidating/duplicating all of the audio and video footage to a seperate, independent location,it should be safe to move your iPhoto/Photos library.

The potential way to circumvent this issues maybe to try and import iPad and iPhoto/Photos video directly into iMovie which would be another solution.

Good Luck!

If you iMac seems to be running slow, please download, install and post an Etrecheck report.

Etrecheck was developed as a simple Mac diagnostic report tool by one of our regular Apple Support forum users and technical support contributors, named Etresoft.

Etrecheck is a small, unobstrusive app that compiles a static snapshot of your entire Mac hardware system and installed software.

This is a free app that has been honestly created to provided help in diagnosing issues with Macs running the newer versions of OS X.

It is not malware and can be safely downloaded and installed onto your Mac.

Copy/paste and post its report here in another reply thread so that we have a complete profile of your Mac's hardware and installed software so we can all help with your Mac performance issues.

Thank You.

Search the forum. They're both junk and won't help with anything.
