Hello, and thank you for using this service.
Sorry to hear you are having trouble. I'll see what I can do to help.
Is the problem that it is not accepting your password?
Hi, if you have to login but have no mouse cursor, just type the first letter of the login name then press Enter, it will reveal the password ***** and you can type in the password ***** proceed to login. Then you can check why the cursor is not working using System Preferences etc let me know if you have any questions, thank you.
Hi, then the keyboard is also not working properly. You should try reset the SMC and try that again.
Here are the steps to reset the SMC:
Then if same try reset the NVRAM. Here are the steps:
Next try Safe Boot:
Then if still not working try booting to Recovery Mode, to check if the keyboard and trackpad work.
Let me know how it goes, if it works in Recovery Mode we should be able to fix this through software not hardware repair.
