System 7.5: Testing Extensions Conflicts w/ Extension Mngr 2/96

This article describes how test for extension conflicts using the Extension Manager provided in System 7.5 and greater. There are several third-party extension managers available for the Macintosh, however none of them provide the ability to use System 7.5 ONLY extensions.
Here are the steps you need reinstall the Apple Extension Manager (if necessary), and test for extension conflicts.

Step 1
------
Open the Control Panel folder located in your System folder.

Step 2
------
Find the Extensions Manager control panel. If you cannot find the Extensions Manager control panel, look for a folder inside your System folder called "Control Panels (disabled)".

Step 3
------
Launch the Extensions Manager

Step 4
------
Either write down all the items with a checkmark next to them, or use the Save Set option in the Sets menu to create a temporary set.

Step 5
------
Choose System 7.5 Only or System 7.5.2 Only from the Sets Menu.

Step 6
------
Close the Extensions Manager (at this point the Extensions Manager will move all non-System 7.5 Extension to the proper disabled folder.)

Step 7
------
Restart your Macintosh computer.

At this point your Macintosh computer is using only System 7.5 or System 7.5.2 extensions.

Step 8
------
Test your Macintosh. Verify that the problem does not reoccur with only System 7.5 extensions running.


Returning Your Previous Extensions
==================================

Step 1

Step 2

Restart your Macintosh
