The only other things I can think of trying:


Sometimes a battery will bulge/expand and affect the keyboard/trackpad. A visual inspection is needed to observe this by removing the bottom cover. Do not do this if you're not comfortable with it. Given that it works in Safe Mode, I don't think this the case though.


Backup your data, preferably twice, once with Time Machine, and once with Carbon Copy Cloner.


Reinstall the OS: https://support.apple.com/en-us/HT204904


If no luck, erase and install a new OS, then try it out before restoring any data or apps (again, backup before erasing the HD): https://support.apple.com/en-us/HT201314

Hi,


Try resetting the SMC: https://support.apple.com/en-us/HT201295


Try booting into Safe Mode: https://support.apple.com/en-us/HT201262


If not luck, and it works on a guest account, I think it will probably work on a new admin user account (System Preferences > Users & Groups). Create one and see if it does work. If so, transfer your data to it, and after you're sure everything is working properly, you can delete the old admin account.

SMC reset did not work, my admin account works, it just doesnt put in the keys when y press them quickly, i removed the password and log in, my problem is that anyone can access it without the password, how do i fix that problem, keyword works fine once inside


Safe mode works, im able to put in my password normally without pressing down and holding the keys, what would be next


Also, noticed theres a difference, in normal boot safari kept annoyingly starting up, i disabled it in start on boot and all but it keep opening every time a restart or turn on the computer

In safe mode i did not have this issu

I don't really understand your first sentence.


After Safe Boot, boot normally and see if it changed anything.


Go to System Preferences > Users & Groups > Login Items > select Safari > click on the minus sign near the bottom of the window.

BY my first sentence: theres nothing wrong with the user, i created another admin user and it didn't fix anything, problem is writing the password, i press de keys and they dont work (only the F top row keys work) if I want to type in my password i have to hold down the keys for 2 seconds or more and delete the extras, but once i log in, keyboard works normally


IN safe mode this problem does not present itself

Managed to fix it, it was the safari app doing this, there was malware/virus/adware very well hidden, used software to sniff it out, deleted it and it stopped the safari from starting, fixed everything else, thanks anyways for teaching me a few things, hope this answer works for people with this problem


Used Avast (for malware and trojans)

EtreCheck (for hidden files and adware)

And normal safe mode for comparing with normal boot
