Older IBM i administration tools are gradually being superseded by Access Client Solutions (ACS), a Java application that runs on all major consumer operating systems, including the Apple Mac. ACS is rapidly gaining functionality, offering unique features such as Insert SQL by Example. To encourage Mac users to adopt this powerful application, I have written installation instructions that work well for me as of today (April 2018).

For background on ACS, see IBM Support’s Access Client Solutions page (current as of this writing, but if the link should ever break, search for “IBM ACS” to find an updated page.)

To begin your installation,  go to the Access Client Solutions “Download” page.

Log In with Your IBM ID and password.

Agree to the license.

Choose your download Method.

Using Download Director:

Or using http, select files individually:

Open the QuickStart guide and follow the instructions for installation on MAC

1 Unzip the application zip file.

2 Go into the unzipped folder.

3 Run the installer, install_acs.

If you get the “can’t be opened” message as shown above , instead of double clicking the icon, right click and you should get an “unidentified developer” message as shown below. Click “Open.”

4. A terminal window will open. Ignore this terminal window. Next, if this a new installation, you should see several yes/no boxes that will help you set up your initial environment. If this is an update rather than a new installation, your previous settings will be preserved.

5. When all of the questions are answered, you should see the “finished” message box.

6. You will find a new application in the Applications folder:

Incidentally, an IBM folder will now exist under your user profile. Your user preferences for ACS will automatically be stored in subfolders under this IBM folder.

7. You can close the terminal window now.

Starting instructions are on the QuickStartGuide as well.

Use Finder>Applications to locate the IBM Access Client Solutions app and double click it:

You may encounter this “unidentified developer” message:

Instead of double clicking it, Right click the icon and choose Open:

Now the ACS program should start. You can verify the version and the Java home path by clicking Help and About.

The installation is complete. You can add your system definitions and emulation environments now.

The Help menu also contains an option to check for updates. It only checks for updates but does not install them. If you want to update to a newer version that the check tells you about, you have go through most of the same steps as the install.

This install was performed on a Macbook Pro macOS High Sierra. I have used the same instructions to install on earlier macOS versions.  The messages may appear slightly different depending on the operating system and security settings you are using.

Good luck and let me know if you have any questions about installing ACS on your Mac.
