Yes, close all applications, install and restart your Mac.
Also, observe the recommended procedure for installing software: repair permissions and close all applications, install, then repair permissions again.)
Input Managers and other plug-ins from third parties can do as much harm as good. They use a security loophole to reach right into your applications' code and change that code as the application starts up. If Safari is crashing, the very first thing to do is clear out your InputManagers folders (both in your own Library and in the top-level Library), log out and log back in, and try again.
So, disable all third party add-ons before updating Safari, as they may not have been updated yet for the new version. Add them back one by one. If something goes awry, remove it again and check on the software manufacturer's website for news of an update to match your version of Safari.
I usually prefer to download updates from the Apple Support site. You can do it either way. I like to have a persistent updater so I can do more than one installation without having to re-download.
Installing a browser update is no different from installing any other update. Just follow the prompts. If you need to restart, you be prompted to do that.
I understand that as far installing a browser update, I was curious about using the Apple Support Site. I have had several people tell me to use the Apple Support Website, but not being very tech savy, I was not sure if I would mess things up goingot the website.
I have even heard different responses about reparing permissions. Some people have told me to use the disc, turn the computer off, insert the disk, and go through the process of somehow getting the Disk Utility up. I have never repaird permissions.
Linc, do you know what inserting the OSX disc, restarting the computer and holding down the "D" does? I was told to do this on another website, but I was lost so I left that website and came back here. I was not following the person on what this procedure was for. do you know?
The following may or may not apply to Lion:
Repairing permissions is important, and should always be carried out both before and after any software installation or update.
Go to Disk Utility (this is in your Utilities Folder in your Application folder) and click on the icon of your hard disk (not the one with all the numbers).
In First Aid, click on Repair Permissions.
This only takes a minute or two in Tiger, but much longer in Later versions of OS X.

By the way, you can ignore any messages about SUID or ACL file permissions, as explained here:
If you were having any serious problems with your Mac you might as well complete the exercise by repairing your hard disk as well. You cannot do this from the same start-up disk. Reboot from your install disk (holding down the C key). Once it opens, select your language, and then go to Disk Utility from the Utilities menu. Select your hard disk as before and click Repair.
Once that is complete reboot again from your usual start-up disk.

Was you reply for Lion OS? I have SL.
Let me see if I can explain this correctly. I was always told you should repair permissions using Disk Utility without doing anything with the OS disk, just use it from the app that is in finder. I never understood this because when I use Disk Utility from the dock I have close to the same permissions that were there before I repaired what showed up. I do a trial run forst to see what shows up and what the Disk Utiity repairs. However when I install the disk when the machine is off, turn it on, select all the correct headins so I am where I should be, go through a repair the Persissions of the HD they are all gone, which I guess means they are repaired. Once in awhile it takes 2 runs at it to repair them all, but it does repair them all or they are all gone compared to what little repairing the Disk Utility does just opening it up when the Mac is on and opne it from the dock or findr and go through the sme process. there are no changes when I do it this way opposed to boting up with the OS disk in the dVD drive, get it opened before the computer boots up and do a repair permissions that way. it will clear away all of the permissions. I never under stood this because I do not know what I am doing most of the time, but people who are experts in here say you do not have to use the disk just use the icon and do it while the computer is on and in its full operation mode. anyway, I think I explained myself correctly.
Thanks for all the info. that will be a good resource. sorry for the sloppy typing but I have to jet.
There’s never a reason to repair permissions, except in the rare case of a permission error involving system files, which you'll probably never see, or a boot failure. The built-in help for Disk Utility says:
Repairing disk permissions
If you see an alert or a message that says your permissions are set incorrectly, you can correct the disk’s permissions by clicking Repair Disk Permissions.
It’s not completely irrational to repair permissions after running a third-party installer, since such installers have been known to set incorrect permissions. Otherwise, repairing permissions is a waste of time.
