  6. That won't update the OS X version, it will just get the latest patches for your current version. But I still don't understand why it is giving you non-English error messages. I don't believe that Apple are producing any further patches for Lion You can buy Mountain Lion An update to Yosemite shouldn't affect any existing data.

    However, there is always a degree of risk in any upgrade. You should ensure that you have refreshed the backups that you, of course, keep of any important data. I press the combination when I turn it on but it never works, it always goes to normal recovery mode. Does anyone know how to fix this or is the manual USB boot up my only option?

    Turned out our old Macbook Pro had originally OSX Lion installed and it was not available through internet recovery on January 25th even if the clock was set up correctly and all possible tricks had been tried. Luckily I had one old external hard drive lying around that had been used as a TimeMachine backup disk on a similar Macbook Pro and it had a nice working backup image of the system.

    I restored on the other troubled Macbook Pro using these backups. I had to remove some old user accounts and do some other cleanup tasks too, but in the end I managed to get it working nicely.

    Could it be Apple has removed Lion-images from the recovery servers? If so, that really is a sad decision. Lesson learned: if you use an old Macbook Pro, do a backup with Time Machine, now. Else you might end up in serious and time consuming troubles. I tried 4 and get the exclamation point in the triangle and a message stating apple.

    It does not ask me to join a wifi network. Same problem…still and thing going worst.. I bought a macbook mid white from a guy on facebook. I put in my apple ID but then it said that the option was temporarily unavailable so i tried the instructions in the post above but it just boots regularly into the utilities…. I bought if from a friend last Feb 7, and still the issue went unresolved. Steve Jobs For sure went to Hell for this product that is full of shit and for selling this product that we cannot use.

    Fix the “App can’t be opened because it is from an unidentified developer” Error in Mac OS X

    May you all rest in peace. Nothing of the above steps worked for me. My only option and what also finally worked was to create a bootable USB with the installer on it. You then again gets send to a recovery mode. But now you will be able to install the OS X. One solution worth adding here though it only works if you have a second computer. Make a time machine backup of a computer that you want to duplicate. Even an old time machine backup can work since this just gets the OS back on your computer. It worked 4 Thank you so much! I bought my late iMac second hand for a great deal thanks to your information!

    Please Try Again Later; Fix. Comments Another fix is to check which Apple store you are connected to, I found I was connected to Apple store Hong Kong recently visited , as soon as I logged back into Apple store UK the two updates that had refused to download for weeks downloaded successfully. It did worked!! It worked when we followed step 4, as we have a second hand Mac.
