I just made a big mistake.

Hi,
I wanted to clean my make and remove everything from it.
So I press cmd R and restart the DD. Now when i start my mac I see a picture of a doc with a question mark.
there is a way to reinstall the OS?
Ps : There is no instal CD when I bought my mac.
With best regards,
Kilian

Try booting into the recovery partition and reinstaliing the OXS via the internet. See:

  • I made a big mistake to change the setting of my Mac book pro to "me only". Now ofcourse It cannot open the login page, for how would the mac know it is me? How can I change the setting back to "everyone"?

    I made a big mistake to change the setting of my Mac book pro to "me only". Now ofcourse It cannot open the login page, for how would the mac know it is me? How can I change the setting back to "everyone"? I have back up in the past but the last month I have not. I really want to keep the data.
    So how can I go in and change the setting, It stays ofcourse at the apple screen with wheel. All info is there and the computer works fine, just cannot use it or have been able to log in.

    wjosten is spot on.  If you really want iCloud, then you will need to acquire a new or second hand MBP that can run Lion.

  • I made a big mistake. I downloaded a Windows version of Adobe Acrobat for my Mac. Is there any way to get that changed?

    I made a big mistake. I paid almost $500 for Adobe Acrobat and realized the whole time I was paying for a Windows version of the software. Is there any way I can change the software without having to buy a new license for the program?

  • I think I have made a big mistake moving from Sky.

    I have just joined BT Infinity 38mb service from Sky on 17/12/14 and I have had nothing but trouble with wireless speed issues since. In the 18 months I was with Sky I never had to phone them once about my service. I always had good connection and good wireless speeds between 23mb to 35mb.
    Now BT is another story my wireless speeds fluctuate between 0.1 to 35mb something that never happened before.
    I phoned customer care on many occasions and most of the time I think they are just reading off a monitor for replies and solutions. Most of the people seem to have very poor expertise in the subject. I have been asked to do the same tests time and time again to no avail. They played about with the settings on many occasions and only made it worse. 
    Our house uses mainly Apple devices and a Macbook pro computer. I think there might be a problem with the router set up and ability for through put for Apple products which I have mentioned many times to see if they could configure the router for this but know one seems to understand. All I get is the easy get out that there is wireless interference and that's it. I point out to them that I never suffered interference with the Sky router placed in the same position and the problems only started when I switched to the Homehub 5. 
    If it's not the setup then maybe the router might be faulty which know one want's to accept or this router must be one of the worst on the market which would contradict BT's marketing claims. 
    I have posted this as to try and get some help as the last customer agent told me to buy another router. Shows what she thinks of the Homehub 5.
    Any suggestions would be very much appreciated.

    Because Customer Services have changed settings in the Homehub I would start again by doing ONE factory reset of the homehub by pressing a pin into the recess button on the rear for about 20 seconds.
    I would then switch off "Smart Set Up". See link how to do that.
    http://bt.custhelp.com/app/answers/detail/a_id/44328/~/switching-smart-setup-on-and-off-on-the-bt-ho...
    I would also give the 2.4Ghz and 5Ghz frequencies different SSids. Just add a 5 to the end of the 5Ghz SSid so you know which is which. Check the 5 GHz Sync with 2.4 GHz: is set to NO.
    Once you have done that "forget" the Homehub connections on all your devices and then re-start them. Log onto the 2.4ghz frequency first and see how it performs. If it is OK then log onto the 5Ghz frequency to see how it performs.If they both perform OK you should then log all devices onto them.
    If you have a problem with one or other of the frequencies you know that is where your problem lies.
    See this link
    http://bt.custhelp.com/app/answers/detail/a_id/44798/~/i-have-problems-connecting-5ghz-and-dual-band...
    As you have a wireless analyser yu should also set the Homehub to the least congested channel on the 2.4Ghz frequency. I find that channel 13 is usually the best despite overlapping with channel 11.
    You can usually leave the 5Ghz frequency on "smart wireless" as it is a lot less congested.

  • Made a big mistake when re-naming clips

    My HD learning curve is getting steeper by the minute...
    Ok, I've spent the entire day capturing HD footage for the first time. Figured it out ok and everything imported fine as ProRes 422. So far so good.
    I needed to change a some clip names to keep things as simple as possible and I read in a tutorial that I needed to rename the files on the scratch disc to keep everything the same. I re-named all the clips in the bin though, even the ones I didn't change and now those clips don't play and I get a general error box popping up.
    Is there a way I can get this clips back? They are on the scratch disc, just not playing from the browser.
    Thanks again

    Hi Adrian
    Can you right click (or control click) on the clips in the browser and choose to rename the file to match the clip?

  • Made a big mistake - reorganized with Windows Explorer

    Even though I knew better, I suffered for a momentary loss of memory and reorganized most of my images in Windows Explorer. 
    I have been tracking down lost files for a couple of days now.  Is there any wholesale way of recovering from this screwup?

    First, don't make the problem any worse
    Stop moving files around in Explorer
    Get using keywords in LR
    Do not use Synchronize or Import to get yourself out of trouble
    Now,
    How many missing files are there?
    Click the question marks on folders before you do the question marks on thumbnails
    Can you resolve the question marks over a period, as and when you need to use the files?

  • Apple you made a big mistake when you made the ipad 3 it was as good as it needed to be when it came down to screen quolity all it needed to make it perfect was an SD slot and a usb slot.

    Apple i think with your new i pad you didnt need the new screen or camera because who realy uses a camera on an ipad for anything more that a scipe call.
    you realy needed to put a usb slot and an sd slot on it to make ease of use better.

    1) You're not addressing Apple here. If you'd like to give them feedback and suggestions, visit http://www.apple.com/feedback/ipad.html.
    2) People use the camera for many things besides a SKYPE call... as there are many other apps that use it. Likewise, most users are fine with storing things on the cloud and not taking up precious space on the ipad for additional slots and cables.

  • You all have made a BIG mistake on our bill

    we have two (2) apple iPhone 5c's on they quote "$45 unlimited talk & text + 250MB." As hard as it may be for you all to understand, 45+ 45 = $90.
    I have checked the data usage and they invoice CLEARLY states we have NO over charge fees. Now on all means I demand you explain why in the world my bill is $362.41. My bill should be $104.66. I am looking forward in the explanation. Thank you

        No need to worry destin_newman! We would be happy to clarify. Have you had a chance to review a break down of your recent bill by visiting http://bit.ly/xB4iTc. Have you reviewed the explanation of the associated charges? Please keep us posted, thanks!

    I do a have back up from time machine but probably from a week ago.   i back up to an external drive and I know I made a big mistake by not backing up before the upgrade.   just wondering if there is another local copy of my most recent iCal as part of the upgrade process on my macbook.

  • Asus Q400a Discontinued -- BIG MISTAKE

    Best Buy has made a big mistake gutting the Asus Q400a. Its newer siblings are in no way comparable. For $650, a quad core i7, 8 GB of ram, a backlit keyboard, and a 750 GB HHD were increadible benefits. Its newer siblings are larger and far more expensive. Not to mention the Q400 was a sturdy laptop.
    It's a real shame. I ended up buying the laptop from Tiger Direct, refurbished. Am awaiting its shipment. Too bad Best Buy lost a GSP sale.

  • I've just bought an iPhone 5S in the UK, seems like a big mistake. I have turned off sync to icloud from the phone for both my contacts and calendar, as told on itunes. However, iTunes still says they are synced from iCloud and wont sync to PC, Fix ?

    I've just bought an iPhone 5S in the UK, seems like a big mistake, but luckily by law we can return goods, which is exactly what is going to happen if I cant get this to work. This is my business phone, not having it functional can cost me money.
    I have turned off sync to icloud from the phone for both my contacts and calendar, as told on itunes. However, iTunes still says they are synced from iCloud and wont sync to my PC, why and how do I fix it so that it doesnt go to iCloud for anything ?
    The phone currently has no contacts or calendar information installed.
    PC is HP Probook 4730s running Windows 7, Professional, version 6.1.7601 Service Pack 1 Build 7601.

    I'm happy you figured it out and just try to keep in mind that not everyone you talk to at support will give the same advice or have the same knowledge. Just like those who contribute to these forums. Sometimes Google is your best friend.
    I agree that Apple could probably make it easier, but as of yet prefer security over freedom. (sound famaliar?)

  • I have just updated the software on my pad to ios7. Big mistake. It is ugly and unpleasant to use. Also, on safari there are icons which I have no wish to use, but can't get rid of. Can I revert to the previous operating system?

    I have just updated the operating system on my ipad2 to iso7. Big mistake. It is ugly and unpleasant to use, and the Safari element comes loaded with icons I will not be using, but can't seem to get rid of. Does anybody know how to change the operating system back to the previous one?
    Thanks.

    Firstly, the icons when you load safari are your bookmarks in the favourite section. To remove them you can simply either delete them or move them to another bookmark folder. To access your bookmarks tap the blue book in the top right corner and then go through to bookmarks and select and edit from there, goodluck :)
