Jumpy curser
My arrow jumps and moves when my fingers on my MacBook Air trackpad. I do not use a mouse. I have opened in safe mode, I have deleted all but my user account, I have run a malware and virus scan with no problems showing, I've tried logging in as a guest user and the problem persists. Ive reset the SMC and NVRAM/PRAM. Nothing has worked. Please help. Thanks.
