Does using secure disk erase make computer run faster?

Does using the secure disk erase help mac book pro to run faster?

No. That option should only be used for sensitive files; the Disk Utility's command for it is meant for secure deletion of files which were insecurely deleted or when the entire drive needs to be securely wiped.

    I was wondering if there is any top free app for cleaning up  the computer from malware, phinishing apps, adware, and othere malicious softwares and make it run faster while booting, on startup and while surfing web. I am using a Macbook pro  with IOS10.8.5, under chrome,safari,firefox net environment. thanks on your help

    I was wondering if there is any top free app for cleaning up ...
    There is no such thing, since the problems you are describing can have various causes. Seeking anything claiming to "clean" your Mac is asking for trouble, since all of those products are scams, whether they are "free" or not.
    If you are having trouble with your Mac, describe what it is. Be as specific as possible. For general recommendations read below.
    There will always be threats to your information security associated with using any Internet - connected communications tool:
    You can mitigate those threats by following commonsense practices
    Delegating that responsibility to software is an ineffective defense
    Assuming that any product will protect you from those threats is a hazardous attitude that is likely to result in neglecting point #1 above.
    OS X already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
    A much better question is "how should I protect my Mac":
    Never install any product that claims to "clean up", "speed up", "optimize", "boost" or "accelerate" your Mac; to "wash" it, "tune" it, or to make it "shiny". Those claims are absurd.Such products are very aggressively marketed. They are all scams.
    Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources.
    Illegally obtained software is almost certain to contain malware.
    "Questionable sources" include but are not limited to spontaneously appearing web pages or popups, download hosting sites such as C net dot com, Softonic dot com, Soft pedia dot com, Download dot com, Mac Update dot com, or any other site whose revenue is primarily derived from junk product advertisements.
    If you need to install software that isn't available from the Mac App Store, obtain it only from legitimate sources authorized by the software's developer.
    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 iCloud, 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.
    Java can be disabled in System Preferences.
    Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
    The same precaution applies to Adobe Flash Player. Newly discovered Flash vulnerabilities appear almost weekly.
    Beware spontaneous popups: Safari menu > Preferences > Security > check "Block popup windows".
    Popup windows are useful and required for some websites, but unsolicited popups are commonly used to deceive people into installing unwanted software they would never intentionally install.
    Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
    If you ever receive a popup window indicating that your Mac is infected with some ick or that you won some prize, it is 100% fraudulent. Ignore it.
    The same goes for a spontaneously appearing dialog insisting that you upgrade your video player right this instant. Such popups are frequently associated with sites that promise to deliver "free" movies or other copyrighted content that is not normally "free".
    The more insistent it is that you upgrade or install something, the more likely it is to be a scam. Close the window or tab and forget 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. Most of these attempts are pathetic and are easily recognized, but that hasn't stopped prominent public figures from recently succumbing to this age-old scam.
    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.

  • Is my HD Dead? Reformat Disk Utility Error: secure disk erase failed with the error could not open disk.

    Hi,
    Fed up with seeing the spinning beach ball I decided to reformat my MacBook Pro...
    After backing up everything on an external hard drive I put in the OSX install DVD, restarted the machine and held down 'C'.
    I followed the install prcedure, clicking next a few times etc...
    I then went into Utilities > Disk Utility. I chose 7-Pass to erase the Macintosh HD and set it off erasing.
    I checked the process an hour in and message on screen read:
    Secure disk erase failed with the error:
    could not open disk
    The internal hard drive no longer exists in the disk utility so I cant retry erasing it.
    The only thing that appears in disk utility is the OSX install DVD.
    I can't even shut down the mac as everything under the apple tab is greyed out!
    I'm guessing this means my hard drive is broken right?
    If anyone has any other ideas of what to try I'd really appreciate that.
    How do I turn the machine off?
    If my hard drive is gone then should I consider getting an SSD drive?
    Any recommendations for such a drive would be great.
    Hope you can help!

    Did you partition the drive?
    Extended Hard Drive Preparation
    1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.

  • Make my computer run faster

    I hope I can get some help here; Recently I purchased Fios in a hope that my computer would run faster after Fios instalation, but no difference at all, then I asked the technician at verizon, they forwarded me to another verizon department to register for a service which will help about the computer run better, and that is $14 a month.
    Is there any other easy way or trick that makes your computer run faster, or what actually causes the computer to slow down? My friend told me that if you don't delete the long emails will slow it as well, is it true?
    Any experienced input will be appreciated

     There are a number of things that may help, but none of them are likely to help a great deal unless your computer is infected with one or more viruses/malware.
    1). If  any of your HDD's partitions  FAT (as opposed to NTFS) format, defragmenting the disk may be helpful. In general NTFS partitions don't need to be defragmented. 
    2). Get rid of the temporary files. It is not uncommon for PC's to end up with literally gigabytes of temporary files. They are left over from software updates, installs, and Internet Explorer SNAFU's. (Do this BEFORE you Defragment the disk).
    Most temporary files either live in directories called temp, have names that start with ~ and/or end with .tmp
    3). Clean up the registry. While Windows will usually still run with a truly amazing number of registry errors, it usually runs better with a lot fewer of them. Software you see such as 'speed up my pc' advertised on Television are in fact registry 'cleaners'. The registry in windows is kind of the like telephone operator before the days of dial telephones.  There are a number of commercial products that do this, but in general you are going to have to buy one.
    4). Unless you are running Vista or Windows 7, try Verizon's high speed internet optimizer to tweak some of the internet settings for better performance.
    5). Uninstall any software that you aren't using.
    6). Use a good anti-virus/anti-malware/spyware program, and scan your HDD's on a regular basis for viruses and other malware.
    Cleaning up your emails is very low on my list of things that are likely to be helpful.

  • Does Endpoint Security Disk Encryption have pre-boot auth?

    Does Endpoint Security Disk Encryption have pre-boot authentication? We looked at it in the past and this feature was not available. Thanks
    Danny

    No. ZESM only does post-login authentication for fixed disk and removable storage encryption.
    If the windows user that logins does not know this password, the encryption driver will not decrypt the stored information. That's the way it works.
    Best,

  • Hi, I have a iMac Tiger running slowly, how can I make it run faster?

    Hi, I have a iMac Tiger 10.4.11 running slowly, how can I make it run faster?

    Look at what is happenning with your Mac when you run Activity Monitor.
    Macintosh-HD -> Applications -> Utilities -> Activity Monitor
    Click on the CPU tab on the lower half of the window to see how much time you are using. 
    Click on System Memory to get statistics on memory usage.  You should have some free memory. 
    When you have lots of page outs more memory will be helpful.  My entry for entry for Page ins/outs is:
    Page ins/outs: 29163/0
    Notice I have 0 pageouts which says that I am not using my harddrive for extra memory space.  Thus, I have enough memory.
    Activity Monitor has a neat feature where it can display a dynamic dock icon.  In Activity Monitor View > Dock icon > Show cpu history.

  • SAP MII. Make iGrid run faster

    Hello Experts,
    While developing user interfaces based on SAP MII I am often using iGrid Display Template. I've find out that speed of iGrid reaction directly depends on its size. I understand that I should not pass large data amounts to Java applets (as iGrid), but even if iGrid has size of 10 columns to 100 rows it is downloading data very slowly..
    Is it possible to make iGrid run faster? Maybe some Java or NetWeaver configuration should be implemented?
    Any reply will be greatly appreciated!
    Thanks in advance,
    Vitaliy

    Hi Vitaly,
    I am not sure which Version of MII you are running but there is one important thing to know about using Displaytemplates like iGrids .
    In the layout section of your e.g. iGrid, you should always define the columns to use/display. If you are not doing this the query is always executed twice (first execution to determine the columns to display and second execution to get the data). I am not sure if this behaviour still exists in the latest mii versions/patches but in previous versions you could double Performance by just defining the column names. so maybe you can have a look at this.
    Best wishes,
    Roland

  • My macbook pro hard drive is 80% full, how do you "defrag" a mac to make it run faster?

    Is there a program in mac to make my macbook pro run faster? On my PC I would defrag it but on my mac, I don't know how to do it. Can someone suggest the best way to tune up my macbook pro to delete unnecessary files and make it run faster?

    There are no degragmenters bundled with Mac OS X, however there is iDefrag a third party defragmenter utility. That said, I highly doubt that defragmentation will bump your computer speed. According to this Apple KB article, Mac OS X is very capable at preventing fragmentation and even the way now hard drives are being manufactured circumvent the possibility of fragmentation.
    Hope this helps.

  • The sample rate in my code is too low. Is there a way to make it run faster?

    Dear Sir,
        I am a LabVIEW customer, and just have a question about LabVIEW.
        We are running a code of "Wirebonder Project", but find the sample rate is too low. I'm wondering if there is a way to make it run faster. (I have
    attached the code here.)
        Thank you very much!
    Yours Sincerely,

    Hi Xian,
    What system are you running this code on and are you using the LabVIEW Real-Time Module? There is a presentation online on Optimizing and Benchmarking Real-Time code with useful related links as well as other articles in the DevZone on things like Benchmarking an Application Using LabVIW Real-Time and DAQmx.
    As you can see, this is not a simple question, so take a look at the information in these links and see if you can narrow down what in your code is running slowly and how much you might be able to improve the speed.

  • How can I safely clean my Mac of old folders etc to make it run faster?er

    How can I safely clean my Mac of old folders, etc to make it run faster?

    The only real and safe way to do this is to do it manually  looking through each folder individually.
    Many third party utilities claim to clean out a hard drive of various detritus, but some times will delete data that it shouldn't  and delete any other  important data that it shouldn't have.
    The only "safe" way to accomplish what you need to accomplish is to do this manually.
    Stay away from the OS X system folder!!!!!
    Hard drive getting full?
    You can download an app called OmniDiskSweeper.
    This app will allow you to see where files maybe able to be delete are located.
    If your Mac is running a fairly recent version of OS X, here are some general guidelines.
    Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
    Have you emptied your iMac's Trash icon in the Dock?
    If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
    If you have images stored in iPhoto,,the only way to weed out duplicates is to do this manually.
    When you delete them, they go to iPhoto's Trash. Remember to empty this when you are done.
    If you store images in other locations other than iPhoto, then you will have to weed through these to determine what are duplicates and what isn't
    If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
    Other things you can do to gain space.
    Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
    Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
    Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
    Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
    Download an app called OnyX for your version of OS X.
    When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
    Typically, iTunes and iPhoto libraries are the biggest users of HD space.
    move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
    If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
    Good Luck!

  • Will an SSD make MOTION run faster?

    As it says, will it run faster?
    I'm currently on a god awful 5400rpm HDD :/
    Motion 5 is slightly slow when rendering my projects, it exports fast and all's good. However when i want to play around with my projects it's so juttery.
    Espcially when i click PLAY, it won't PLAY, it'll stutter A LOT.
    Thoughts?

    Heya Matt,
    Motion does most of its heavy lifiting with the graphics card. An SSD will technically make Motion run faster, but upgrading the gfx card will produce the best performance increase. Have you tried optimising your playback performance in the Render settings? Draft quality, quarter resolution, etc.
    Hope that helps!

  • My iMac seems to be running slower lately. Is there anyway to make it run faster?

    My iMac seems to be running slower than when I first bought it. Is there something I can do to make it running faster? Also can anyone recommend a good antivirus software for Mac. Thanks.

    The best antivirus application is none at all, keep OS X up-to-date and educate yourself about Malware by reading Viruses, Trojans and Malware - Prevention and removal: Apple Support Communities.
    In order to speed up your iMac we need to know some basics about it first such as what version of OS X is installed, exactly which iMac you own, how much RAM it has, what size is the HD and how much free space on the HD. Without those fundamentals we would only be guessing.

  • I have a Macbook pro 2.2 GHz Intel Core i7 (2011). Will Lion, Mountain Lion or Marverick makes it run faster or slower?

    I have a Macbook pro 2.2 GHz Intel Core i7 (2011). Will Lion, Mountain Lion or Marverick makes it run faster or slower?

    Snow Leopard is still the most efficient OSX from Apple.  I have a late 2011 MBP running Lion with no performance issues.
    I suggest the following;  Install 8 GB RAM if you do not have that already.  (The best sources of Mac compatible RAM are OWC and Crucial).  The newer OSX's are trifle more RAM hungry.
    Partition your HDD and install one of the newer OSX's in the new partition and try it out.  This allows you to 'retreat' to Snow Leoprad if you find the newer OSX is not to your liking.
    Also note that the newer OSX's do not support PPC applications.  That means that there is a possibility that some of your current applications will not work and may have to be updated or replaced.
    Ciao.
