    Your Mac runs maintenance in the background for you.


    Third party so called Mac cleaning utilities can cause more harm than good.


    Mac OS X: About background maintenance tasks

    I totally concur with Carolyn.


    Avoid the so called "cleanup" applications. They cause more problems then they solve.

    I have used it sparingly both on my PC and iMac with no issues on either.  I only use those features I think I need at the time; no "shotgun" cleaning.  I think it's good to securely erase files etc.  I do rely on OS X background maintenance tasks for the most part.  So far, it's never messed anything up on either Safari, Chrome, or Firefox.  Onyx was also recommended, but I'm not sure a Mavericks version is out yet.  You are correct, however, when you say that the Mac will survive quite well without all these "utilities."

  • Allan Eckert Level 9 (50,709 points)

    OS X will secure erase files if you feel that is necessary. Personally I only think that is necessary when you are getting rid of equipment.


    From my testing of the so called cleanup applications, I have found them either to not do what they claim they will or they do dangerous things without any warning what so ever.

    Thanks; I am aware of the Disk Utility etc. that will erase free space etc.  After having some financial information "possibly hacked" a few years ago, I have been overly careful.  It's a real pain changing credit card and bank info, and I'm not even sure it was compromised, just warning from the bank.  I use my mac at home, but also have a PC laptop, IPad and iPhone; all are on my network, so I limit the information on all the equipment and watch carefully whatever is there, and how it is shared.  I guess with NSA, it is probably futile anyway!

    You don't need to use Disk Utility. Just "Secure Empty Trash" from the Finder menu or hold down the Command key and right/control click on the trash icon.


    You absolutely do not need any "clean up" software on a Mac. It will only cause problems, never solve them.


    If you are concerned about security, you are really focusing on the wrong place. Getting rid of that PC is all you need to do.

  • jerryoster Level 1 (0 points)

    Well said!

  • Allan Eckert Level 9 (50,709 points)

    If you are concerned about some of your data being hacked have you ever considered placing the data into an encrypted disk image?


    I keep all my financial and personal data in encrypted disk images just in case.



  • jerryoster Level 1 (0 points)

    Another good idea!

    Had a similar "PC" problem. Very scary (don't ask). So I understand being pathologicly nervous about this. If I may suggest (to Apple) an effective way to reduce customer concerns would be to define (for non-computer people), those things mentioned as concerns regarding vulnerability. Ex: Which port/s are used by "X" traffic? I have a lot of traffic w/ "Telnet" though it's often pointed out as being "more" vulnerable (by those who know more about this then me)


    I had a "Nortan" security add-on a while back. Not to thrilled about it except for the multi-layerd firewall. That at least gave me the IMPRESSION of greater awareness and hence control. True or faulse...

  • Allan Eckert Level 9 (50,709 points)

    If by Nortan you mean Norton then that is one of the worst things to install on a Mac. The only thing that I know of that is worst then Norton is MacKeeper.


    So I would have to vote for false.

    Well known TCP and UDP ports used by Apple software products

    Besides the fact that Norton / Symantec's products run poorly on Macs, an impression of security or control is all it will do. Such impresions are detrimental to actual security due to the false comfort it you may perceive from using products like it.


    The functions of a "firewall" are frequently misunderstood. Whoever first came up with that term as it applies to computers either regets it, or should.


    OS X already includes everything it needs to protect itself from viruses and malware. Keep it updated with software updates from Apple.


    The question you should be asking yourself is "how should I protect my Mac":


    • Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
    • Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
    • Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
    • Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
      • Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
      • Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
      • Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
    • Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
    • Don’t install Java unless you are certain that you need it:
      • Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
      • Disable Java in Safari > Preferences > Security.
      • Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
    • Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
      • Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
      • Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
      • If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
    • Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
      • The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
      • OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
      • Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
      • If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
      • Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
    • Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.


    Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

    All these are excellent suggestions! (I am going to close my $500 million Nigerian Bank account!)
