If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else.You'll use the Recovery installer, rather than downloading it from the App Store.C. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. If you already have an external drive with OS X installed, start up from it. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. You don't need a DVD if you're running OS X 10.7 or later.B. Start up from the Recovery partition, or from a local Time Machine backup volume ( option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same.If you’ve forgotten the password, you will need to reset it before you begin.If the startup progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. You must know the login password in order to log in. Ask for further instructions.Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.The login screen appears even if you usually log in automatically. If you don't see the words "Safe Boot" in the startup screen, you haven't started in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Then restart as usual (i.e., not in safe mode.)If the startup process hangs again, the problem is likely caused by third-party software that you installed. Do this until the available space is more than 9 GB. Deletion isn't complete until you empty the Trash again. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. If you ever have another problem with the drive, replace it immediately.If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.If a desktop Mac (without a built-in keyboard) hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. You might be able to start up in safe mode even though you can't start up normally. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to log in by using the arrow keys or the cursor to select the password field and typing your password as usual.If Step 3 fails, the startup volume may be full. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Use a different keyboard and/or mouse, if those devices are wired. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Follow these instructions to eject it.Press and hold the power button until the power shuts off. If you're using a USB keyboard connected to a hub, connect it to a built-in port.Sometimes a startup failure can be resolved by resetting the NVRAM.If there's a built-in optical drive, a disc may be stuck in it. If need be, replace or recharge the batteries. In that case, erase the volume and restore from a backup. You might choose to tolerate one such malfunction in the life of the drive. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. If any problems are found, repeat until clear. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.Do as in Step 11, but this time erase the startup volume in Disk Utility before installing. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.Reinstall the OS. Then restart as usual.If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Look for the line "Permissions repair complete" at the end of the output.
