Step 2: Test individual extensions and control panels
To test an individual extension or control panel for compatibility, follow the steps below.
1 Start up your computer while holding down the Space bar.
Holding down the Space bar opens the Extensions Manager control panel during startup.
2 Release the Space bar when the Extensions Manager control panel opens.
3 Turn on the item you want to test by clicking its name to put an X beside it.
4 Close the Extensions Manager to continue startup.
5 Try the same actions that caused the problem.
If the problem does not occur again, then the item is probably compatible with Mac OS 7.6.
If the problem occurs again, the item is probably incompatible. Open the Extensions Manager and click
the item’s name to remove the X.
6 Repeat steps 1 through 5 for each item you want to test.
