Q: iMac 5K Late-2014 apple logo blinks at boot

Hello,

 

I recently had problem after activating Kapersky Internet Security 2015 on my iMac. I uninstalled it and then my mac refused to continue startup after logging in. It was stuck on a plain back screen. I then reseted NVRAM/PRAM and I got white lines at boot after logging. I resetted it a second time and it seems gone. However, I noticed than when I boot and you see the apple logo with the loading bar, the screen seems to blink two or three times. Is that normal?

 

Thank you,

 

Have a good day,

 

François

iMac (Retina 5K, 27-inch, Late 2014), OS X El Capitan (10.11.6)
