Hello,
I have a problem when running MAC. I will not get to the sign-in page. Pressing CMD + V will display this message (figure). There is a repeated "code signature validation failed" error associated with Avast.
Can anyone advise me how to fix the problem?
Thank you for your help.
Erase the drive and reinstall OS X. If you don't know how that is done, then be sure to tell me what Mac model you have. To find the model identifier open System Profiler in the Utilities' folder. It's displayed in the panel on the right. You may also find the complete model information by selecting About This Mac from the Apple menu.
Uninstall Avast software. Try starting in Safe Mode instead.
Thank you. Problem solved. Over the Utility I reinstalled the OS.
Unfortunately, safe mode will also not start. Loading will stop on the Apple screen.
Code signature validation failed
