During the installation, when you get to the window where you are to click the Install button, you must first click the Customize button and choose packages for your computer. Click the little arrow next to the patches category to reveal the individual packages. Select Intel or AMD packages, not both. Select SSE2 or SSE3, not both, depending upon the capability of your processor. Select the Combo Update to get the latest version of OSX. Select other packages only if you know your computer can use them.

For resolution selection, you can try the Displays preference in System Preferences.


If that doesn't work, then you need some proper drivers for your video card. What kind of video card do you have?


Also, during boot, you can hit F8 to get to a boot prompt. At the prompt, type:




And see what resolutions are available.


Then type:


"Graphics Mode" = "1280x1024"


where 1280x1024 is the resolution you want. You must use the quote marks. When you find a resolution that is acceptable, you can add it to your boot.plist file.


Edit the boot.plist file at "/Library/Preferences/SystemConfiguration/com.apple.Boot.plist" and add the following shown in bold:

<key>Kernel Flags</key>


<key>Boot Graphics</key>




<key>Graphics Mode</key>


You can edit the file by dragging it to the Desktop and editing it with TextEdit, then dragging it back, answering the 2 resulting dialogs - Authenticate and yes to replace, then followed by using Disk Utility to repair permissions on the OSX partition.


Or you can do it via Terminal with this command:

sudo nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
