How to uninstall Safari 5.1

I just did the most recent Software update and installed Safari 5.1, but I am still running Snow Leopard. Big mistake. Several websites that are important to me are not working properly. Not happy at all.


How do I uninstall 5.1 and go back to 5.0.5?

MacPro, iMac, MBPro 2.66 Intel Core i7, MackBook 2 G2, various G5's, Mac OS X (10.6.6), 1 TB Time Capsule (early 2009) & Airport Express

Just fyi - your double posting.


I dont know. I would need to know the whole situation. Did Apple try to reinstall 5.0.5 for you in the 4 hours that you were there? Apple will create a new user for everyone regardless of what the problem is because its the quickest way to get you out the door.


If safari was slow and pages werent loading like the OP said, id say prob was Safari 5.1 and not your user settings.


"packedup my data" thats cute. im gonna say that from now on 🙂

So after digging around a bit, Chase at Basecamp said it looks like that URL in the screenshot that I sent him is actually an API URL, which is why it's returning that raw content.


He gave me the correct URL, and that seems to have solved my problem. I am not quite sure what an API URL is. The only differences in the two URLs was that the API one has a "%20" inserted in the middle of huntington in the URL, and the good URL has a "#" after comments instead of a "/".


I don't know if when I launched Safari 5.1 the first time, it tinkered with my URL?


All seems to be at peace now with 5.1.


Thanks for all the advice.

i have a copy of 5.0.5, can i just delete 5.1 and drop 5.0.5. back in?


No. You'll create bigger computer problems if you write over Safari 5.1 with 5.0.5. System files have changed with Safari 5.1, which will be unreadable by v 5.0.5.


I'm not sure or confident about the Time Machine approach mentioned by others here. IMO, the best approach is to reinstall Snow Leopard via your DVD Installer.


Once Snow Leopard is reinstalled, run the 10.6.7 Update Combo, (download this update to your computer before running the reinstall), which includes Safari 5.0.5.


After the Update Combo is finished, open Software Update in the Apple Menu and download and install 10.6.8, plus any other updates appearing there (other than Safari 5.1).


When finished, open Disk Utility found in your Applications>Utilities folder. HIghlight your HD on the left and select on the right panel "repair permissions". Once complete you ought to be good to go.

I'm running OS X 10.6.8 and simply replaced Safari 5.1 with my copy of Safari 5.0.5. This worked out fine with no need to do the 10.6.8 combo again.


I also just tried the webkit nightly build of Safai and so far it seems to have corrected the problems I was having with Safari 5.1. I'd post the " webkit nightly build" link, but last time I posted a link the mods slapped my wrist. Perhaps you can Google it if you'd like to try it.

I recently reinstalled the 10.6.8 combo update because I wanted to go back to Safari 5.0.5 because 5.1 was giving me lots of problems. 10.6.8 combo worked fine and Safari 5.0,5 is back and works great. Repaired permissions but Software Update tells me there is no new software. That is wrong. I should have a few updates available including obviously Safari 5.1. I deleted cache and Software Update preferences but it still says there is nothing available.


Anyone know how to completely clear out Software Update so it will scan my drive for new software? There must be a file to delete that I am missing.

Sigh. Big sigh, from a non-techie. I know how to set the home page in preferences. I've downloaded 5.1 also. The preference won't stick. I've tried google, and other sites, it just opens in nothing. And I tried to run some videos on a construction material site, not working. I honestly don't know if I'm going have the chops to figure out how to uninstall 5.1. I just thought I'd add my list of what's wrong---

i had the same problem as all you

for me i am running windows 7 32bit version and looked around through my firewall settings and managed to find the solution through my registry.

i am still trying to find a solution on mac but if you do know how to reset this on airport or whatever you mac experts call it use and post it

here's the bottom line: open command prompt in administrator mode and type netsh winsock reset, it will reset and then restart pc your safari 5.1 will work.

to open command prompt

  1. click start
  2. type in search box cmd
  3. right click
  4. select run as administator
  5. if a box comes up which says "do you want to allow the following program make changes to the computer?" select yes
  6. you may need to put the admin password in ask your admin
  7. command prompt will be open


this is just for people who do not know how to open command prompt i expect that you do🙂🙂🙂😁

And exactly which problems would those be? If every piece of Safari (any version) is deleted, and a new version is downloaded/installed, exactly what problems are going to occur?


Appreciate your insights.
