Suddenly super long boot time and sluggish cursor
I changed the LCD on my 2011 MBA. Everything seemed fine. When I put the webcam cable on, the connector fell off so I replaced it with an I/O board from a 2009 MBA. After that, the MacBook air is super slow to boot and when I finally get to finder the cursor is sluggish and everything is lagging. So I put back the original I/O board. Same super slow response. I have tried to reset SMC, NVRAM, even if I take out the SSD and boot from a USB install it takes ages to boot. I formated the SSD and installed a fresh OS X 10.13.6. It behaves super sluggish no matter what I do. Has anyone experience this?
Here is a picture of the webcam cable connector fallen off
- I did a hardware test. No problems found.
