Sometimes, when working on a Mac computer, the left-right scrollbar is missing. This frequently happens with the Grade Center. This is easily solved with a few changes to your Mac.
- Click on the Apple menu at the top left of your screen.
- Select “System Preferences.”
- Choose the “General” icon (the top, left icon).
- Select “Always” as the Show scroll bars setting.
- Close the System Preferences window, refresh your browser window, and you should now see all scroll bars in Blackboard.
