Stuck loading bar, Safe Mode doesn't work
I have a stuck loading bar on my iMac after leaving it for several hours. I tried booting in safe mode, but I get the same result. I cannot get to a login screen.
MacBook Pro, Mac OS X (10.6.8)
How To Do A Factory Reset
Selection A should be used on computers that came with Lion or later when factory new. These models had no disks included when new. Selection B is for Macs that came originally with Snow Leopard or earlier. These models shipped with Software Restore disks when new.
A. Factory reset of your Mac - Apple Support
B. Factory Reset Your Pre-Lion Mac
Follow these instructions until you get to Step 5 of Factory reset of your Mac - Apple Support. At Step 5 you will need a Snow Leopard DVD or the installer disc that came with the computer.
Snow Leopard Erase and Install
- Insert Snow Leopard DVD into the optical drive and restart the computer.
- Immediately upon hearing the chime hold down the C key.
- Release the key when the Apple logo appears and wait for the loading to finish.
- After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities' menu. After Disk Utility loads select the out-dented disk entry from the side list (mfgr.'s ID and drive size.) Click on the Partition tab in the Disk Utility’s right window. Set the number of partitions to one (1) from the drop down menu. Click on the Options button and select GUID, click OK button, set the format type to MacOS Extended, Journaled. Finally, click on the Apply button.
- After formatting has finished quit Disk Utility. Continue with the OS X installation and follow the directions.
- When the installation has finished the computer will restart into the Setup Assistant. After you complete the Setup Assistant you will be running a fresh installation of Snow Leopard. Open Software Update and install the recommended updates.
- If you are planning to sell or give your computer away, then do the following: After you reformat your hard drive and reinstall Snow Leopard, the computer restarts to a Welcome screen. To leave the Mac in an OOTB (Out Of The Box) state, don't continue with the setup. Instead, press Command and Q keys to shut down the computer. The Setup Assistant will guide the new owner through the setup process after he/she turns on the computer.
- Download and install Mac OS X 10.6.8 Update Combo v1.1. if needed. It is not needed if you are selling or giving away the computer.
