SPINNING RAINBOW CURSOR

When you get the spinning ball, go to your Apple menu on the far left side of your menu bar at the top of the screen and choose "Force Quit". You will be given a choice of programs to quit, highlight Safari and click on the Force Quit button. (a browser is a program that gets you onto this internet and allows you to visit different sites. Safari come with your Mac, it is the Apple browser, although there are lots of different ones out there, there's no need for me to confuse you with too much information)

A couple of things; first, when you post, please don't use CAPS, it is akin to shouting, second, have you tried to force quit your browser? Which browser do you use? (by the way, the spinning cursor is affectionately known as the spinning beach ball or pizza of death).

First of all you should try repairing your permisssions using disk utility which is worth doing and cant do any harm.
Also, If you have sight problems you could increase the resolution of your display in the display system preference. also check out the universal pane.

About the Spinning Cursor --
Do these, after repairing permissions, as Daniel suggested,
and report back.

1. Empty your cache (Under Preferences) & History settings via the Safari menu

2. Trash your Icons Folder:
HD>Users>Home>YourName>Library>Safari -->Icons
Restart Safari and a new folder will be automatically regenerated.
(This folder saves favicons of all the sites you visit. Needs cleaning periodically -- or you can change that file's preferences to "Read Only"
rather than "Read & Write." This will keep it from growing in size.)

About the type size:
Go into Safari Preferences>Advanced.
Under Universal Access, the first box:
"Never use font sizes smaller than . . ."
Try larger sizes than what's there now.
Click the checkbox and put in 12, 14, or
whatever makes it easier for you to read in Safari.

Let us know how you're doing, OK?

You may not necessarily be able to use the apple menu in the browser once it stalls.
if this is the case, try clicking on the desktop in the background to switch to the Finder, at which point you should be able to get the force-quit window.
