How do you disconnect "history" on a Mac computer?

I haven’t a clue. If anyone knows please let me know.

I presume you mean the history on Internet Explorer? Go to EDIT-preferences
in IE, select “advanced” in list on left and enter 0 in box marked “remember the last ---- places visited”

I’ve been using a Mac since 1985 and I haven’t a clue what you’re asking.

Well, OK, sorry. I’ll guess a bit. Didn’t mean to jump on you but it’s a very imprecise question.

Do you mean in a browser?

Which browser? (Netscape? Internet Explorer? iCab? Opera? OmniWeb? AOL? Lynx?)

Do you mean you want to prevent auto-complete from filling in places you’ve been in the URL field? Or get rid of a drop-down list of recently visited sites? (some browsers have those, some don’t)
Or prevent someone from entering about:global as the URL and bringing up the history of where you’ve been?

If this is close: Go to System Folder, find Preferences folder, dig around for folder specific to the application (e.g., “Netscape Preferences”). If it has a file named History.html or similar, throw it away or edit it with a text editor.

If you mean instead something different…umm, maybe “Recent files” list in the File menu of Word, Excel, FileMaker, etc? Go to the Edit menu (usually) of the relevant program, go to Preferences, and root around for a checkbox “show most recent __ files in File menu” and uncheck it.

If you mean “Recent Documents” in your MacOS 9.x Apple Menu, open the folder and toss out the aliases; or to stop it from tracking recent documents at all, go to the Apple Menu Options Control Panel and uncheck “show recent documents”.

If you mean how do you unanchor your Macintosh from the passage of time so that it exists for all eternity and has all the features of Macintoshes yet to come while still being covered by your 1998 service contract, you’ll have to download some shareware for that. Try the Info-Mac archives, search for “MacinTimeless”. Don’t forget to pay your shareware fee!
