It happens sometimes when opening files from external sources (like Brightspace), and it can get stuck for weeks unless manually interrupted.
Force Quit Excel using Apple menu → Force Quit.
Disable the Solver Add-in in Excel settings.
Reopen Excel, and everything should run normally again.
Optional Cleanup (Advanced)
If the Solver add-in keeps coming back, delete its reference:
1. Go to this folder:
~/Library/Containers/com.microsoft.Excel/Data/Library/Preferences/
2. Look for a file like com.microsoft.Excel.plist and delete it (this resets Excel preferences — including add-in loading behavior).
3. Reboot your Mac.
