my MacBook air shows a white lock and does't accept any usb or cd-rom
iMac, OS X Yosemite (10.10.1)
Hi,
Startup your Mac while holding down the Option key. That should launch the Startup Manager window where you can select the startup disk then click Restart. Then open System Preferences > Startup Disk > MacintoshHD > Restart.
This is the third post for your problem. We appreciate it when you do not do this. An answer has been posted in your previous two posts.
Install Lion Through Maverickson a New HDD/SDD
Be sure you backup your files.
- Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears. Wait patiently - 5-15 minutes - until the Utility Menu appears.
- Select Disk Utility from the Utility Menu and click on the Continue button.
- After Disk Utility loads select the drive (usually, this is the out-dented entry with the mfgr.'s ID and size) from the side list. Click on the Partition tab in Disk Utility’s main window.
- Under the Volume Scheme heading set the number of partitions to one volume. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the Format type to Mac OS Extended (Journaled.) Click on the Partition button and wait for the process to finish. Quit Disk Utility and return to the Utility Menu.
- Select Reinstall OS X from the Utility Menu and click on the Install button.
[Permission to use part or all of the above has been granted by Kappy, exclusively, to theratter.]
If you have access to another computer, if the 2 computers have the correct cable connections, try the Target Disk Mode. You can then download the OS installer on the other computer and install it on the Air.
If this is the display that you are seeing and do not know the password, bring the Mac into an Apple store genius bar.
Ciao.

We? Who is We? Probably a good idea to speak for yourself.
Oh, and what is exclusive permission from Kappy? Please clue me in, how does one go about arranging something like that? You mean that even if I gave proper attribution, I wouldn't be able to quote from that, all or in part? Can you provide documentation for this claim of yours? I have never seen anything like this before at ASC. Very interesting.
Good friend of Kappy & when Kappy quit he passed his notes to theratter. 🙂
