Mac Tip - Free Up Some Hard Drive Space

Fed Up - Full Hard Drive Syndrome

Getting the "Start-up disk is full" warning?  Here are some tips that can help you reclaim some drive space.

Backup, Backup, Backup

Backup (as in save important stuff just-in-case) before you do anything that will significantly impact your computer's internal storage.  If you have an external hard-drive with at least 2x the capacity of your internal drive, consider using Time Machine to create automatic backups of your data.  Time Machine, built into your Mac, will automatically check your computer every hour for changes and back them up incrementally.  This means it will only save changes, not re-copy all of you data over again.  You can use an external drive physically attached to your machine (USB, Firewire, Thunderbolt) or storage on your network, often referred to as Network Attached Storage or NAS.  One of the best and easiest solutions is to use an Apple Time Capsule.  It is easy to configure and you can "set it and forget it."  Anytime you are on the same network as your Time Capsule, Time Machine will back up your drive in the background.  For more information you can read about it here.

Alternatively, you can backup certain files manually to any storage device.  But the important thing is DO IT!  Got it done?  It's OK, I can wait.

Empty the Trash

You may have heard of hoarding.  Your computer is notorious for it.  It loves to hang on to old junk.  Teach it some new habits by learning a few of your own.  Does your trash bin look like this?  If you are unsure what is in it, double click to open it and see its contents.  Junk, right?  Click "Empty Trash." Now.  Depending on how long it has been since you took out the trash, you can reclaim a Gigabyte or two or even more.
iPhoto Trash
Actually, this is not the only trash can in your system.  Did you know that all those pictures you "deleted" from iPhoto are probably still there?  iPhoto has its own trash so you will need to review its contents and delete there too.  Depending on the size of your photo library and what you have trashed over time, this could release a HUGE amount of disk space.
If you use iMovie to make those cute kitty-cat videos for posting on YouTube, the files can add up fast.  Videos are the single most users of disk space in your computer.  Consider purging them especially if you have them backed up elsewhere.

Downloads Folder

Another place to check for bloat is your Downloads Folder.  This folder is the place were all the photos, videos, PDF's and apps you have collected from Safari or your preferred Web browser are kept.  Clean it out.  You'll feel much better.

Apple Mail, the Hungry Hippo

Apple Mail stores every attachment of every email you have ever retrieved using it.  If you are a mailbox packrat, then Apple mail (or any desktop email client you use) could be holding several gigabytes of space that you can free up.  The easiest and first thing you can do is to make sure that your deleted mail items are indeed, well, deleted.  Go to Mail preferences, (keyboard shortcut command+, (⌘,) and select the Accounts Tab.  Look at the Trash settings for each account you use.  Also, check the Junk Mail settings while you are at it.

Advanced (But not Difficult) Ways to Look for Old Files

Still need some space?  Remember, you have backed up your stuff right? Right?  OK, let's move on.  Your Finder is a powerful tool.  Did you know you can set up special searches that will be saved as "Smart Folders" that will always update?  For example, suppose you want to see all PDF files on your Mac that have not been opened in the past year.  Make a Smart Folder that always shows PDF's a year old or older.  Here's how you do it:
  1. Use the search bar on Finder to start a search for files of Kind PDF.
  2. Click on the Plus icon for more filtering options such as "last opened date" or Name.
  3. When you have added all the desired filters, click Save and name the folder.
You will now have a "Smart Folder" that is always up to date.  There you can review and purge files you no longer need.

There's an App for That

Also, there are several third party applications available on the Mac App Store as well as online that you can use to see what is taking up all the space on your Mac and clean it up.  The Utilities category on the App Store is a good place to start.  DaisyDisk is one of my favorites.  It is easy to use and gives you a visual representation of what your disk storage space looks like.  It is not free, but at $9.99 it is cheaper than a arterial McDonalds attack and you get it forever.

Bottom Line...

With good housekeeping and regular backups of your data, you can keep your hard disk humming along for years.  Well, I gotta go... Time to empty the trash.  "Coming, Honey!!"

Do You Need to Defragment a Mac’s Hard Drive?

--> Do You Need to Defragment a Mac's Hard Drive? About Focus on Macs In my mailbag this week, I found a couple of questions about defragmenting a Mac's hard drive. This question usually comes from new Mac users, or individuals who switch to the Mac from the Windows environment, where disk defragmentation utilities abound. Some individuals want to know which third-party disk defragmentation app they should use, or wonder why there is no defrag tool in OS X. Courtesy of Apple OS X does have disk defragmentation capabilities, but they're built into the system rather than a separate tool. Since OS X 10.2, Apple has included automatic defragmentation in the Mac OS. In essence, the Mac OS has built-in safeguards that attempt to prevent file fragmentation from occurring; it's also able to repair fragmentation, should it occur. This means that for the average Mac user, there really is no reason to worry about disk defragmentation, at least not as ...

Learn To Code

Even if just to get a better understanding of how computers work or learning how to customize your browsing experience, knowing the basics of coding opens ones eyes to possibilities once only known by a few.  Learn To Code Planet Cocoa If learning to program is even a minor goal for you,  Code Year (via  Brent Simmons ) might be just the encouragement you need. They promise to email you on a weekly basis with coding lessons to help you achieve your goal. I'm one of those computer programmers who downplays the difficulty of the profession, because "if I can do it, anybody can do it!" On the other hand, I have faced challenges that made me question whether I'm vaguely qualified for the job. What it boils down to is that programming is both incredibly simple and impossibly hard, like so many important things in life. There was a time when nobody knew how to write literary prose. The geniuses who invented it shared their special tool with a ...

Tips: Delete duplicate entries in "Open With..." dialog in Finder

Duplicates!!! When you control+click (or right click if you have enabled that option) on Mountain Lion, and there seems to be several duplicate applications listed and/or apps you no longer use, here is a Terminal shell script that will fix that.  Just copy and paste the code below in a Terminal window. /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain user (Terminal can be found using Launchpad or Spotlight) After pasting, hit the Return key and allow time to run, then type "killAll Finder" without the quotes, and Return.  This will rebuild the "Open With..." menu.   If you do not see an immediate effect on the lists, restart your Mac.   Should be no need to restart. (Thanks, JK) Duplicates and old apps gone! If you wish, you can make a Service that will do it using Automator as well: Open Automator (Launch Pad or Applications folder) Create...
