Installation Issues

Listed below are notable installation issues in Mac OS 9.1...

Starting Up from Mac OS 9 CD
Apple's install recommendation Apple recommends starting up from a Mac OS 9 CD prior to installing the Mac OS 9.1 Update.

Installer Moves Files/Folders
Installing Mac OS 9.1 does some unexpected moving around of files on your drive. For example, it renames the Applications folder to "Applications (Mac OS 9)", and moves the Internet, Apple Extras, and Utilities folders into it. The name of this folder can then no longer be modified from the Finder. OS 9.1
  1. Lotus Notes
    This moving around can cause some unexpected glitches with Lotus Notes. After upgrading from 9.0.4 to 9.1, Lotus Notes Client v 5.0.6 no longer launches. It turns out that this error is the result of the Mac OS 9.1 installer moving the Internet folder to within the Applications (Mac OS 9) folder. Notes hard codes the path of the application location during Installation; move it or change folder names in that path, and you're done.
There are a couple of workarounds:
  1. Create a "new" Applications folder and move items from"Applications (Mac OS 9)" folder and delete it.
  2. Before using the installer modify names of files/folder that it tries to move.

    If you want to avoid all this moving around, put a symbol (such as *) at the start of the name of the relevant folders before installing Mac OS 9.1. The update will create an "Applications (Mac OS 9.1)" folder with the updated copies of SimpleText, DiskCopy, etc.. You can then replace the older versions (still in their renamed folders) with the new ones.
  3. Alternatively, you can use ResEdit (or other resource editor) to unlock the folder name and change it back to "Applications."

The updater deletes several preferences files, including Finder Preferences.

Apple Menu Items
It also removes items from the Apple Menu Items folder, such as the Note Pad application (but the old Note Pad had been reinstalled into Apple Extras). Meanwhile, it puts things back that you had removed, such as Scrapbook or Stickies. It also puts fonts in the Fonts folder, overwriting existing fonts with the same name if present.

Mac OS Public Beta
Installing Mac OS 9.1 prevents the Classic environment from running in the Mac OS Public Beta.

NOTE: The final Mac OS X release will require Mac OS 9.1.

PowerBook 3400 with Mac OS 9.0.4
Don't update your hard disk drivers (when installing 9.1) if you updating a PowerBook 3400 running Mac OS 9.0.4.

PowerBook 1400 & Password Security
Turn of Password Security when run on a PowerBook 1400 before installing Mac OS 9.1. It is no longer supported.

GX Desktop Printers
Disable any GX Desktop Printers before installing Mac OS 9.1 and then reset them only after the installation is completed.

20th Anniversary Mac
Turn off Virtual Memory before updating a 20th Anniversary Macintosh to Mac OS 9.1, or else the installer may crash.

Third-Party Accelerator Cards
If you have a Power Macintosh 6100, 7100, 8100, or 9150 with a third-party accelerator cards may not install Mac OS 9.1.
