How Do I uninstall Safari?

Those who for some reason do not want to continue using the fastest, safest version of Safari (4.0.3) and want to revert back to an older version, rather than find out how to correct their faulty system, can do so by performing an archive and install:

An alternative strategy, if you really don't like Safari, is to try one or more of the many other browsers available for the Mac. They are listed here:

But there may be another way, BUT this is for TIGER users only:

Download Safari 3.2.3 from Apple's Download page. http://support.apple.com/downloads/Safari3_2_3_forTiger

Quit Safari.
Delete Safari
Delete the receipts file at /Library/Receipts/Safari4.0Tiger.pkg
Empty Trash

Mount the Safari 3.2.3 dmg file and install it.
Restart your Mac
Repair permissions

All should be good with Safari 3.2.3.

I am unable to verify whether this works. Try it and post back with results!

by "delete Safari" do you mean drag its icon from the apps folder to the trash?

Yes, I assume that is what he means. An older version of safari will not install if it detects a newer version in your system.

As for your 'crawling issue' try this first:

(First, if yours is an Intel Mac, check that Safari is not running in Rosetta, which is enough to slow it to a crawl. If you are running Snow Leopard, run Safari in 32 bit not 64 bit.)

Do you have enough RAM? Less than 1GB can cause slowness. Is your hard drive too full? Less than 15%, or 15GB, of free space can also cause slowness.

Adding DNS codes to your Network Settings, should give good results in terms of speed-up as well as added security:

Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu, and in the box marked 'DNS Servers' add the following two numbers:

208.67.222.222
208.67.220.220

(You can also enter them if you click on Advanced and then DNS)

(An explanation of why that is both safe and a good idea can be read here: http://www.labnol.org/internet/tools/opendsn-what-is-opendns-why-required-2/2587 /

Open DNS also provides an anti-phishing feature: http://www.opendns.com/solutions/homenetwork/anti-phishing/ )

Wikipedia also has an interesting article about Open DNS:

Whilst in System Preferences/Network you should also turn off 'IPv6' in your preference pane, as otherwise you may not get the full speed benefit (the DNS resolver will default to making SRV queries). If you want to know what IPv6 is:

This is Apple's guidance on iPv6:

http://docs.info.apple.com/article.html?path=Mac/10.5/en/8708.html

Click on Apply Now and close the window.

Restart Safari, and repair permissions.

If that didn't do it, then try this as well:

Empty Safari's cache (from the Safari menu), then close Safari.

Go to Home/Library/Safari and delete the following files:

form values
download.plist

Then go to Home/Library/Preferences and delete

com.apple.Safari.plist

Repair permissions (in Disk Utility).

Start up Safari again, and things should have improved.

I guess that Safari 4 just doesn't like my 10.4.11 OS in my trusty old G4 Giga ethernet.

It should do, but for Safari 4.0.3 to work in Tiger it is essential that you have installed security update 2009-002 or later:

Mac OS X Tiger 10.4.11 and Security Update 2009-002 or later
