Clean Mac Hard Drive Delete Mac TrashApple Macintosh computers are great, but they all seem to have hard drive storage issues. Here I’ll show you how to:

1. Clean up your hard drive and eliminate clutter

2. Permanently delete files in your trash

3. Delete all cookies and cache system wide

4. Repair permissions on your mac files

5. Edit many system wide options using OnyX


First Get OnyX

I’m able to do all of the above with a free Macintosh tool called OnyX. Here is how you install it:

  • Go to
  • Select the version of OnyX based on the operating system you are using
  • You can find your operating system info, by clicking the Apple icon and then About This Mac
  • Choose to open with DiskImageMounter
  • Drag the OnyX logo into you Application folder
  • Double click on the OnyX icon to open it

How to Delete Mac Trash

If you have a Mac, eventually you will have a problem deleting your trash. Laugh it up PC’s! OnyX will delete the trash everytime.

  • Just click on the tab in Onyx called Utilities
  • Select Trash in the toolbar
  • Make sure the Delete radio button is selected
  • Click the Execute button

This might take a bit to process, but I guarantee it will permanently delete and over write all of your trash. It will even delete files that are locked or in use, so watch out.

Clean Up Mac Hard Drive

PC’s have a tool called CCleaner, that deletes cookies, and other garbage files system wide. You can do the same thing with OnyX:

  • Click on the Cleaning Button in OnyX
  • Click on the Internet tab
  • Select what you want deleted, by clicking in the check boxes
  • Click Execute and everything is gone

    I use a MAC OS X version 10.7.3 – After attempting to delete files, many appeared in my “All My Files Folder” which when I then attempted to delete any of them I was given a choice to click on either “Delete The Alias” or “Fix The Alias”.

    Clicking on “Delete The Alias” gives me the message – The Alias: plus an ID number of the specific file I was attempting to delete, and then the message – “can’t be opened because the original item can’t be found”.

    When I then clicked on “Fix The Alias” I get the message:

    “The operation can’t be completed”.
    “An Unexpected error occurred (error code – 43)”

    How do I delete these error code – 43 files that I’m now unable to delete by any means, and are cluttering up my list of legitimate files?
