You may have updated your Mac from Mavericks (OS X 10.9.x) to Yosemite (OS X 10.10.x) which might disable Java or remove it.  To ensure WNC4 functions correctly on your computer you will need to update Java (see the advice on RefWorks' Write-N-Cite 4 troubleshooting page).

Make sure you install Java for OS X 2017-001 (or later) - if you have another version of Java please uninstall it first and restart your computer. (see link below).

If you are still running Mavericks (OS X 10.9) you can download Java by navigating to the Apple Icon > System Updates, or go to: - you need Java Runtime Environment 8 instead.

Once you have reinstalled/enabled Java please check for Microsoft Office updates.  You can check for Microsoft Office updates by opening Microsoft Word and navigating to Help > Check for Updates

Restart your computer. If Java is enabled, WNC4 should run (our thanks go to Dudley Knox Library for publishing this advice).

If you do not have a copy of MS Office you may obtain a discounted version online from the Apple Store for Education (just log in with your email address).

If you need further advice please contact giving full details of your problem and also the versions of Java, OS X, Word and WNC4 that you have installed.

Please note that WNC4 is not compatible with Word 2016 on a Mac. You are advised to use Word 2011.

If you want to use Word 2016 on a Mac (available from Office 365) then switch to RefWorks Citation Manager. You may install RefWorks Citation Manager (RCM) from Word 2016's Insert tab > Add-ins > Word Store > then search for RefWorks - select the RefWorks Citation Manager add-in and add it by clicking the 'trust it' button. You will then be requested to enter your legacy RefWorks 2.0 log in details before you can start using it.

Alternatively, new users may choose to switch to the new version of RefWorks 3.0 now and use the RefWorks Citation Manager add-in if you only have Microsoft Word 2016. Please note that this version is only compatible with RefWorks 3.0. For details on switching to RefWorks 3.0 see the links below.
