Is there any risk installing Adblock on mac downloading online?

I do not like those popping advertisements when I am net-surfing. I wanna install adblock downloading it online. Is there any risk to the computer doing so? How effective is it? Suggestions please.

    Sorry ... I read but was unfortunately distracted from your original post.  You have a system that came with Lion.  The Lion that is on your system is only for your computer and cannot be downloaded from the app store again because you never purchased it officially through the App Store.
    Try this for making an external USB/DVD copy of Recovery on an external disk.  internet is still required for reinstall, though, I believe: http://support.apple.com/kb/HT4848.  But at least you have a separate Recovery Partition if you ever need a fully new and empty internal disk.
    Your assumption is incorrect. Although he may not be able to download it from the App store he can download it directly for the Apple servers using the recovery partition on his original drive.
    All you have to do is start the install routine and then point the install to an external hard drive. Once the download is finished the computer will reboot to start the install. At that reboot disconnect the external drive so the install can not start. Boot the computer back into the OS on the internal hard drive, which is what will happen automatically once the external drive is disconnected. Then connect the external and copy the files from it that were downloaded. Right click on that downloaded package file and select Show contents. In the contents of that package is a file called InstallESD.DMG. Copy that file out of the package and burn it down to a DVD or USB thumb drive and you now have the Full Lion Installer. I have several of them laying around on different hard drives and 2 USB thumb drives which I have used to reinstall Lion on my 15" MBP.
    Sorry OP I should of just typed this out in my first post.

    Hi, original poster here. I did not realize this would generate more discussion so I never checked back. I still had my warranty, so I took it to the store and got it repaired. The original problem I had was a screen with this icon flashing when I attempted to boot it up:
    When I took it to the store, they told me that my computer was unable to communicate with the hard drive. I had this same problem three times in two months where this screen reappeared. Each time I went back to the store and they said the cause was different, but they were all hardware issues that physically made it impossible to communicate with the hard drive. After the third time, they simply replaced my laptop and I haven't had the same problem.
    So in short: The reason you can't reinstall or move anything when you encounter this screen appears to be because nothing can communicate with the hard drive in the first place. You can't reach the disk or anything on it. So I don't believe it's possible to do anything besides take it to a physical store and have it fixed.

  • Safari was very slow in opening up Google sites.  I found a discussion thread that suggested changing the "Configure IPv6" setting to "Off" in the System Preferences, Network, Advanced, TCP/IP section.  That seems to work well.  Are there any risks?

    Safari was very slow in opening up Google sites.  I found a discussion thread that suggested changing the "Configure IPv6" setting to "Off" in the System Preferences, Network, Advanced, TCP/IP section.  That seems to work well.  Are there any risks to leaving the Configure IPv6 setting to Off?

    Nope. You can always reverse that if you choose.

  • Is there any print screen option in mac book like we have in other make notebooks

    is there any print screen option in mac book like we have in other make notebooks

    Make a screenshot:
    CMD + SHIFT + 3 = whole screen
    CMD + SHIFT + 4 = you can select a area
    CMD + SHIFT + 4 and after that press space bar = select a window
    That will take a screenshot to your Desktop. If you additionally hold down the CTRL key the picture is taken to the clipboard and could be pasted to a program (like Preview or Photoshop ...)

  • Is there any risk in buying a refurbished iPod?

    Buying a refurb and saving about £60 seems too good to be true. Has anyone bought a refurbished iPod and is there any risk?
    Thanks for your help.

    Im sure there is a risk but its small in my opinion. refurb means it is restored to factory specs. I bought one a year back and have had no trouble. I would make sure the company you buy from is a respectable one.

  • Are there any risk if i provide my new ipad serial number to someone else?

    Hi, i have a new ipad2 with full one year warranty because i haven't turn it on and connect it to ituns yet. i want to sell it from ebay and someone ask me to have the serial number. are there any risk if i provide him the serial number? ie. he can use the serial number to register with his account and start the warranty.

    The warranty starts from the day you purchased it, not the day you first use it.
    With the serial number the buyer will be able to verify the warranty status at the page below:

    In theory, he could register the device, but what would be the point?

  • Is there any way I can take a Microsoft online course on my iPad?

    I'm new to using my iPad, so forgive me if I sound ridiculous. Is there any way I can take a Microsoft Online course using this blastard iPad?
    Maybe an app or something?

    If its working with word, excel, etc no you cannot. Some classes have you do work on the programs and submit a finished product. Sorry if thats the case.
    EXCEPTION:
    I did some work for a computer class last year. It was all online tutorials etc. You went though the tutorials online(fake access or word) and didnt need the programs on your computer. That I could do, but it was flash player. I had to download a flash browser(puffin) and it worked. With this case YES

    With Snow Leopard if you delete a file (put it the trash) and then do a secure delete it's gone.
    The OP is adressing SSD's in particular. Neither Snow Leopard nor Lion have the ability to secure erase an SSD of a single file by user action. This because SSD's write data in pages, but can only delete in blocks. Secure emptying of the trash on an SSD is no different than a non-secure erase, as the controller will not permit erasure of blocks until the entire block is freed, which is almost never the case with even group file deletion. Erasure is simply the re-writing of the "allocation table" that the pages are no longer in use.
    SSD's are only rendered "erased" of previous data after an indeterminate period of use, and re-use that would eventually free blocks for re-write, and then actually over-written.
    TRIM helps speed this process, but does not alleviate the block versus page issue.
    Some additional info.

    Restoring the iPhone will reload its firmware.
    Plug the iPhone into (the current version of) iTunes on your computer.
    Let it sync.  Then choose "Restore" from the iPhone's summary page in iTunes.

  • Is there any way to turn off the download function in safari offline reading list?

    Is there any way to turn off the download function in safari offline reading list?

    Don't think so.  The point of the offline reading list is to allow you to read it later without going online.  It has to download the content to make this possible.
