    Mac OS 8.1 installs various system extension that may appear to be damaged when inspected by certain utility software when in fact they are not.

DISCUSSION

    The Mac OS 8.1 extension files listed below are not damaged and function normally. These files, installed by the Open Transport installer package, have extra space allocated in the resource portion of the file.

    Some utility programs report those extra bytes as a damaged file. These extra bytes do not cause these files to function improperly. It is not necessary to use utility software to fix or correct these them.

    The following files have these extra bytes:

    • Open Tpt AppleTalk Library
    • Open Tpt Internet Library
    • Open Transport Library
    • OpenTptAppleTalkLib
    • OpenTptInternetLib
    • OpenTransportLib
    • AppleTalk control panel
    • TCP/IP control panel

    Note : Open Transport 1.3 to 1.3.1 Update Version 1.0 was released on 1998-02-13. This update removes the extra bytes of unused data. This update requires the North American English Mac OS 8.1 Update and version 1.3 of Open Transport and is not required by any localized version of the Mac OS 8.1 Update.

    For more information on this update please see article 30410: Open Transport 1.3 to 1.3.1: Update Information .

    Note : Mac OS 8.1 Update was posted again on 1998-02-27 to prevent these files from appearing to be damaged. If you downloaded the Mac OS 8.1 Update prior to this date, it is not necessary to download Mac OS 8.1 Update a second time. Instead, download the OT 1.3 to 1.3.1 Update.
