MacOS – Microsoft word 2011 not correcting words in OS X

Two things you can try :

1) Make sure you have the latest updates installed. Office 2011 has been updated since release, so it pays to ensure the latest versions of all applications are installed.

2) Perform a Repair Permission on your Macs hard disk. This has been known to cure slowdowns in a a few Applications including Office 2011. Repair Permissions is a feature of Disk Utility found in the Utility folder in Applications.

Since the Windows version pre-loads some of the apps at boot time, here's how to do a comparison.

1. Start with your Mac turned off.
2. Press the power button and start your timer.
3. Wait for the Mac to boot, then open Word. When Word is open, stop your timer.
4. Then repeat the test for a Windows PC, starting with the PC turned off.

Also note that Office 2004 was written for PowerPC chips, but you're running it on an Intel Mac. That slows things down because Intel Macs have to translate all that PowerPC code into Intel code. If you upgrade to Office 2008 or 2011, you'll have an Intel version of Office for Mac, and it should run faster.
