How to Free Up Space Used By Time Machine’s Local Backups on Your Mac

Time Machine doesn’t just back up to external drives. Enable Time Machine on your MacBook and it will create “local snapshots,” too — potentially taking up over 100 GB of disk space on its internal storage.
 
These local snapshots appear as “Backups” when you look at the visual overview of storage in the About Your Mac window.CHRIS HOFFMAN has written a good article about  how you can free up that space and get more room on your Mac.

Boosting Performace of Older Macs

Older MacBook Pro computers made between 2009 and 2012 are routinely retired because they seem slow or will not hold a charge.  These models can have several more useful years with some simple and inexpensive upgrades.  The newer models - like the mid 2012 has a CPU almost as fast as the 2015 models.  Apple has made major improvements in battery life and the beautiful retina display however the perceived speed hasn't changed much.  If you bought your son or daughter a shiny new Mac when they started college in 2012, that computer, with a few upgrades would be a perfect computer for their high school sibling.  

3 Simple Upgrades for about $250 can save you from buying a new $1,800 Mac.

Mac / OS/X Security Recomendations

  • Keep your software up to date.
    • Always update your Apple software from the Updates section of the Apple App Store.  Click the Apple icon on the top left of the display, select "About this Mac" and click on Software Update.  Never update by way of a link on a webpage or an email.
    • Update non-Apple software from within the application or from the company's web site.  Beware of ectra or bonus software downloads during updates.  Oracle's Java updates are notorious for installing unnecessary toolbars.  Less scrupulous companies are often the source of unwanted add-ons that can steal data or show unwanted ads.
  • Make Time Machine backups
    • Select the option to encrypt backups.
    • Keep at least two backups each at a different location and at least one disconnected.  See my article on The Dangers of Cloud Sync.
  • Install anti-virus software.
    • I use Sophos Home, a free AV program for Macs.  Sophos.com
    • Install anti-malware software
      • I use Malwarebytes from Malwarebytes.org.  
  • Set a login password for your Mac
  • Keep your Mac behind a good firewall.

A Fix for Mac OSX Archiver Hanging Up -Update

A few years ago I experienced problems with Mac Archiver under Mountain Lion and posted a fix related to permissions.  Today Archiver again would not function and just hung when called.  The following fixed the problem and is much faster.  Start Activity Monitor from the Utilities folder in the Applications folder.  Sort the list alphabetically by process by clicking on the process name column heading.
