I need Internet Explorer 5.5 to access my classes

Maybe a bit better explained on: [Changing your Firefox’s useragent string using the User Agent Switcher Plugin|http://dotdoh.com/?p=191]

However, (and I have no idea) there could conceivably be something unique to IE5 that is really required to use the page. I suspect it is more likely somebody has something in there to check you're not using an old browser that can't use the site's features, but basically can't imagine anybody using anything other than Internet Explorer.

The switcher I linked is not guaranteed to work. Check [http://chrispederick.com/work/user-agent-switcher/faq>

Latest Mac version of IE I find is IE5.2.3...

Other possible solution is an APP to run Windows®, Parallels...

VmWare Fusion...

And Wine...

Go to Safari -> Preferences -> Advanced -> click "Show Develop menu in menu bar". Then, under the Develop Menu, choose User Agent, and then select one of the versions of Internet Explorer. Quit Safari and then launch it again.

If the website still chokes on it, I can't think of anything else to try, other than asking your instructor to buy you a PC with Windows installed on it.

You can set the User Agent in Safari (use newest supported Safari, for security) and
if you have OnyX by Titanium Software, you can use its configuration options to have
the Safari's User Agent stay put. Otherwise, it will revert once shut down to a standard
view and the Developer menu bar may disappear from the Safari browser.

{Or I should say, this worked in mine; perhaps in an earlier Safari and it was carried forward.}

Once you enable the Developer menu (and User Agent) with OnyX utility, a free tool
from Titanium Software, the menu and ability to have Safari seen by web sites as a
different browser stays enabled. {And OnyX is good for much more: maintenance.}
When you have OnyX in the system, launch it, enter password then note this path:
OnyX> Parameters> Safari> Enable debug menu>

For some reason, this keeps my Safari's (including latest version) developer menu
and User Agent from going away; it is always present. If this does not work for you
then there may be some other thing going on in my computer. There was a tweak
a few years ago, a freeware, that also enabled the User Agent; doubt I installed it.

• Or you could get Camino browser and see if its user agent lets you use stubborn
web sites engineered by fools with stone axes and wooden clubs, in IE clothing.
Even Opera may allow you an option to fool those sites made by M$ followers.

Good luck & happy computing! 🙂

Could try:

Doesn't Safari's user agent revert to default after restarting?

Oops, you are right. Nix the relaunch.

Check this out.

Run IE on Your Mac with ies4osx

 Cheers, Tom 😉

Good suggestion, but: "ies4osx makes use of wine to install and run IE.
And wine needs a Intel processor, sorry." OP has G5.

OOh, I missed the G5, thanks!

The rare & elusive VPC7 might be an option.
