Hi, Linc. Thanks for your reply. I managed to get an answer from another website, which is shown below:
Logging in without a Mouse
1. Type first few letters of username until it’s highlighted
2. Type Password
3. Check Bluetooth pairing in System Preferences
If cursor still doesn’t show:
CMD+SHIFT+G to Go To Folder
2. Enter /Applications
3. Arrow keys down to System Preferences
4. CMD+O to Open
5. Type Bluetooth into the Search field
6. Press Enter to open Bluetooth preferences
7. CMD+N to set up new device
In my case, the cursor did show after I logged in. However, I will buy a USB mouse as a back-up!
