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.

Protecting Macs from Viruses and Malware

March 11, 2016

For many years, computer viruses and malware were mostly the concern of Windows users.  Mac users faced very few threats. This has been atributed to the Mac's sibgle digit market share and, some have argued, a more secure product.  One common misconception was that Macs were somehow imune from viruses and malware.  While the number of threats may pale in comparrisln to Windows, Macs are indeed suseptible to attack and more and more are appearing.  The time has come for Mac users to make secutity a priority.   

In the last few weeks, researchers have found the first Mac Ransomware malware in circulation.  Ransomware is software that encrypts the files on a computer making them unuseable to the owner.  The person controllling the malware then demnads a ransom to unencrypt the files.  In most cases, the victim has only 72 hours to pay or the ransom or the malware author threatens to eraswe the key that is needed to restore the files.  Regardless of the size of your business, the loss of data can be davastatiung.  

Add these new threats to hardware failures and theft and the need for a well thought out and executed computer protection plan is more important then ever.

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.

Fixing the "ACL found but not expected on ..." error during OSX Volume Repair

Symptom - Running the OSX Disk Utility program and selecting Verify Disk permissions results is multiple error of ACL found but not expected on [filename]”  While these errors can be safely ignored (ACLs are Access Control Lists) it does make reading the results of the disk verify difficult.    Fix - Fletcher Tomalty has written a python script that can be run from the command line to remove these unexpected ACLs.  The script uses the OSX Disk Utility to find the files and then does a sudo chmod -h -N on each of them.

Flycut - App of the week

Flycut is an example of great software that does one thing well and solves a problem that almost everyone has.  It is a clipboard utility for the Mac that allows for practically limitless number of 'copy' items to remain available for paste.  The standard Mac clipboard keeps just one copy item - each subsequent copy replaces it so it's copy, paste, copy, paste, copy, paste often switching between windows or tabs of a browser each time.  Flycut is a small "resident" program that allows for multiple copy commands to be stored for later pastes in any order.
