Restriction reformatting Mac - command-do not work

Hello! A friend of mine gave me an IMac refurbished (2008) from his place of work, and I'm desperately trying to reformat since there are some problems with the audio and the internet. Unfortunately the computer does not allow me to go into the menu to reset when I restart and it ignores completely any keyboard (command-R) input and it restarts normally as I never pressed a button. Can someone help me please?

You have posted this in the wrong forum, this is the forum Pages and AFAIK r command does nothing when starting and I have much doubt, you need to reinstall the system, except if you change yourself to be the admin. Here again, you have other ways to change details and log. OSX is not Windows, you do not what you do on Windows. Determine what the real problem is before trying what is essentially Voodoo.

You have the DVD to reinstall the system, assuming that there is a DVD player? In this case, you put in and reboot holding down the key 'c' (for the CD) to start with.

Otherwise, install a new OS on an external hard drive with the Setup file and resart off th external hard drive by holding down the option key when the computer reboots and choosing this drive.

    Would you like to share why you must do a clean install?

    You can try the recovery of the internet (which will work if your older model has been updated to enable of): hold command + Option + R until you see a progress bar (take a while). It will connect you to the Apple servers. When you see the utility window, choose disk utility to erase your disk and when you're done, choose to reinstall OS X.

    PS: Correction: I think not yours can be updated; in this case, you will need the original installation disks to wipe the drive and reinstall.

  • "" > Tap to open sticky notes ' command would not work.

    "> Tap to open sticky notes ' command would not work. I try to use sticky notes & I think it's the way to get to sticky notes. It is a command line in windows section 'help '. Nothing is more fundamental than that. Is there a work around?


    Hi novelty451,

    The command used to open sticky notes on the command line is StikyNot.exe. To use this command, try the following steps:
    a. Click Start, type cmd and press to enter.
    b. in the command prompt, type StikyNot.exe and press ENTER.
    c. you should now see a sticky note.

    There are other ways to open sticky notes, see the following articles for more information.
    1. see Sticky Notes open
    2. see Notes sticky keyboard shortcuts

  • Why does "Reformat text on zoom" not work on my HTC Desire?

    I can't reformat text on zoom"to work on my HTC Desire.

    I have folleowed the instructions on this page with no luck.
    http://support.Mozilla.com/en-us/KB/zoom-in-and-out#w_reformatting-text-on-zoom

    Everyone knows this?

    Hmm, sorry it doesn't work. It could be that the text on the page is not small enough to trigger the behavior of reformatting. (Our defaults are perhaps not aggressive enough on the reformatting of text). If you install the Add-on more great text and use its options to increase the size of "double-click" at 18, then reformatting works when you double-tap?

    You use the browser in landscape or portrait mode? It should be more noticeable in portrait mode.

    For example, the text on gnu.org should recede if you double - tap on the orange box at the top of the page with the option "Text of the reform" is enabled.

  • Tilde shortcut command does not work

    I changed some keyboard shortcuts in the preferences system recently and never since the command ~ shortcut does not work.  I tried that in Chrome and Xcode, the apps that I use most, it won't work and I get the loud beep error System.  I posted the stack overflow, but received no response.  I did some research and reset my shortcuts keyboard by default, but this did not work.  I'm more frustrated as I use it in development, and there is no obvious solution on google.

    Look in system-> keyboard-> shortcuts preferences.

  • I tried to make a video call on MSN live messenger 8.0.1 under Leo of MAC but does not work

    I tried to do a video chat a MSN live messenger 8.0.1 under the new lion of MAC OS10.7, but may not have to work. Why

    No windows is running. Live MSN messenger 8.0.2 is the MAC version of messenger

    Thanks for the clarification.   I don't know exactly where your version of MAC will be supported but I would first try to ask here:

    http://windowslivehelp.com/product.aspx?ProductID=2

    (Portal of the Windows Live Messenger WLSC)

    Oh.   Maybe you're in the right place, after all, simply not redirected properly.   Other posters on the WLSC asking about are apparently sent here (at the forum of responses from Mac Office).

    Did you get your Messenger by installing a Mac version of office 2011?

    http://www.Microsoft.com/Mac/Messenger/

    (Microsoft search for)
    + Mac Messenger MSN "8.0".
    )

    Messenger for Mac 8 is included in each edition of Microsoft Office for Mac 2011

    FWIW, there is no mention of MSN in any of these opportunities, although he asked insistently.   It seems that's just sort of alias now Live ID in which case the WLSC might still be a better place to ask for help, depending on what you mean by "does not work".   ; )

    Good luck

  • Some of the Netstat commands do not work

    Some of the main controls of Netstat do not work (only 5 commands work out of 11). I am particularly interested in the command n (address/Port # s in digital form). I think that my system may have been compromised, and some software disabled. Y at - it a new version of Netstat I can download. I looked in the update and the Download Center, but did not find anything.

    Hi Seeker96,

    You can use TCPView rather than Netstat.  It provides the same information than Netstat (with the - n switch), it maps IP addresses to their domain names (and much more) and it has a GUI firendly.  You can see what is happening in real time, so it allows you to focus on the current network activity.

  • The command does not work on my ESXi.

    Hello people.

    How are you?

    I use SSH to loggin to the ESXi and when I want to execute the commands available, ESXi tell me which command not found!

    I use the "su" command to become root, but orders do not worked.

    $ esxcli

    -bash: esxcli: command not found

    $ su

    Password:

    # esxcli

    bash: esxcli: command not found

    #

    How can I solve it?

    You do not understand... after that 'su -' just try to run the esxcli command, or if you do not '-' with the su command, just run esxcli to folder/usr/sbin .

  • Organize some commands will not work

    Help, please! These commands are essential to the way I work in Illustrator - probably for you too. Keyboard shortcut for arrange, object - send to back, to Front, etc.. None of these commands will run. What I am doing wrong?

    I can drag the layers in the layers panel, but does not work orders reorganize no matter where I call them-the object on the top menu, right click on the object itself, or the way the more useful, keyboard shortcuts: CTRL + SHIFT + [etc.

    I do not use transparent traces, no paint, no groups. I'm in Normal shooting mode.

    For what it's worth, the Select commands run perfectly well. CTL + ALT + [or CTL + ALT +] no problem with one of these.

    I use the default keyboard shortcuts.

    Win 7 Pro 64 bit, Prem CS5.5 Prod. No difficulty in CS4...

    Thank you.

    [EDIT: reset preferences (moved AIPrefs, restart) but it did not help.]

    This is what I think and not you angry against me because I think that this is a user error.

    I think that you think that you can select an object on a layer and send it to the back and some how is behind a layer that is below the layer that lies in the object.

    It works that way.

    It will send it only in the back of the objects in the active layer also applies if you want to come forward, he will come only at the front of the objects in the active layer.

    I ask it is the error of the user and it works very well and there is no need to reinstall.

    Now obviously I can be wong on this subject if you wrote something that indicates that it is the case.

    If you understand how it works and that's another problem then you have a software conflict on your computer can be anything from a police, recent update, new application or public service or even some strange setting in another application.

    But the reason for which no answer is no one can figure out how to operate not so that they could not help. But I read your message several times and realized what I think the problem.
