3 Installing and Removing Oracle Instant Client

Perform the following steps for installing or uninstalling Oracle Instant Client for Apple macOS (ARM64). All installations require a Basic or Basic Light package. All other packages are optional.

Installing Notarized Oracle Instant Client Software DMG Files

  1. Download the desired Oracle Instant Client disk image (DMG) files for Apple macOS (ARM64) from the Oracle Instant Client Downloads page:
    https://www.oracle.com/database/technologies/instant-client/downloads.html

    Note:

    You can use the stapler utility to check if the DMG files are notarized. For example:
    $ /usr/bin/xcrun stapler validate instantclient-basic-macos.arm64-23.3.0.23.09.dmg
Processing: instantclient-basic-macos.arm64-23.3.0.23.09.dmg
The validate action worked!
  2. Mount all the desired DMG packages.
    For example:
    /usr/bin/hdiutil mount instantclient-basic-macos.arm64-23.3.0.23.09.dmg
  3. Run the following commands to copy the volume contents to the install location, for example, /Users/user-name/Downloads/instantclient_23_3.
    For example:
    cd /Volumes/instantclient-basic-macos.arm64-23.3.0.23.09
sh ./install_ic.sh

    Note:

    Run install_ic.sh only once, from any instantclient-*-macos.arm64-23.3.0.23.09 directory.
  4. Eject the mounted Oracle Instant Client packages in Mac Finder.
    Alternatively, use the hdiutil unmount command in the terminal to eject the mounted Oracle Instant Client packages. For example:
    /usr/bin/hdiutil unmount /Volumes/instantclient-basic-macos.arm64-23.3.0.23.09
