Hi Gyndocal1,
Based on your description, you cannot find terms via Find Function in Excel 2016 for Mac. I would like to suggest you check the following:
1. Ensure the Office 2016 for Mac is up to date.
2. Click Search in Workbook to check if the issue occurs.
3. Create a new workbook and check if the issue persists.
Besides, please provide the information below:
1. Does the issue occur to one workbook or all workbooks?
2. The version of the Office: Excel > About Excel.
3. The version of the operating system for your Mac.
4. Detailed steps and related screenshots about how you use the Find Function and encounter the issue.
Regards,
Yoga
