You’ve purchased your Mac. Now you’re going to want to take care of it. The key is to keep your Hard Drive running as efficiently as possible. In this tutorial we’ll offer a few pieces of advice as well as show you how to use the tools that come built in with your Mac to keep your hard drive in its best condition. Throughout this process you might even discover you can gain some space back on your Mac.

Keep in mind!!! If you’re constantly getting the rainbow spinning pinwheel, that can also be a symptom of hard drive failure. If this is the case, please backup your data ASAP and bring your Mac to an Apple Store. None of these tricks will help if your computer is experiencing hardware failure.

Just for fun: Before you try any of these techniques be sure to write down how much free space you currently have and then how much you have after applying these simple tricks. Let us know the results in the comments section below.

    What happened to your website? I can’t even find the list of classes that used to be so easy to look through.

      Hi, Jim. Thanks for visiting! We’ve made a ton of huge upgrades as you can see. Our old site lacked the ability to sort by topic and the search function wasn’t very powerful. The only view available was the list of videos in production order. Now you can search by topic, choose a category like Mac, iPhone, etc, see the latest videos in many categories, etc. It’s far more user-friendly and it puts the content front and center.

      Are you wanting to see an unsorted list of all of our classes regardless of topic? If so, I can look into adding that feature if there are any other requests for it.

    Well, David, you just lost me.
    I am using Firefox, and none of the videos work.
    They seem to work in Safari, but “thank you but no thank you”.
    I’ll look back later to see if you could fix it.

      Sorry to hear that you’re having trouble, George. Do you happen to have any blockers or other add-ons running in Firefox? Since another browser works and Firefox is not working for you, that’s the place I would start. I just downloaded Firefox to check it myself and the site works great, so add-ons or plug-ins would be the first place to start looking.

      • George

        Thanks for your answer. Yes I have blockers, but I know how to switch them off :-)
        I fixed the problem by uninstalling Firefox and re-install it. I purposely use version 28 and now it works.

    David, I have imovie version 9 on an imac but it keeps on crashing- any ideas what the problem is?


    • Mark from PCClassesOnline

      The first thing I would do is to re-download and reinstall. There may be an update since you got it that would solve the issue.

    when Yosemite first went online, I downloaded it and began using it. A few months later, I tapped my mouse and low an behold the screen went total green. I got it to boot up in safe mode and it allowed me to run the repair disc. It did not work. I contacted a Mac tech and after 6 hours and 4 different techs, I finally got to a tech that knew what was wrong. Yosemite had a glitch. So with his help we went to the program page, typed in about 4 lines of data and problems solved.

    When i press command + R, it does nothing at all. The screen just stays black forever.

    Even holding down just the option key (which I believe is supposed to give me options from which drive to boot from) does the same thing…

    Any ideas?

    In this class, you mention that laptops, such as a Macbook Air, will go bad at the 3 to 4 year mark. Is this no matter how well a person takes care of a laptop?

    • Mark from PCClassesOnline

      He actually mentions hard drives going bad, not specifically laptops.

    Hi David,

    First off, I would like to say thank you for providing your tutorials – I enjoy them and find them useful – especially the iMovie tutorials.

    Here’s my concern:
    Even though I strive to save my work on an external drive, rather than my hard drive, the hard drive capacity keeps shrinking – here’s my latest info:

    35.83 GB free of 120.1 GB

    My computer is a Macbook Pro (Retina – Late 2013) with Yosemite 10.10.3

    What is the best way to find the culprit and free up more space?

    Thanks in advance!
