Frequently Asked Questions

Why did my spell check stop working after a Mac upgrade?

Major macOS upgrades can sometimes cause compatibility issues with older versions of software. In this case, a known bug in older Microsoft Word builds prevented the spell check background process from functioning correctly on the new OS.

What should I do if Microsoft AutoUpdate does not open?

If clicking 'Check for Updates' does nothing, you can manually download and install the latest version of the Microsoft AutoUpdate tool directly from the official Microsoft download center.

Will I lose my unsaved work if Word keeps freezing?

If Word completely freezes, you may have to force quit the application (Command + Option + Esc). Fortunately, Word's AutoRecover feature usually saves a temporary copy of your document, which will be offered to you the next time you open the app.
