macos security updates and startup mac hangs on apple logo screen ?

Hi Apple Folks,


When I update macOS 10.13 security updates, after restart mac hangs on apple logo screen ?

Progress bar is full or almost full.


Probably some (old) software extensions or kernel extensions ?


Thanks in advance for your help.

Hi,


Safe Boot from the HD, (holding Shift key down at startup), does the problem occur in Safe Mode?


Safe mode attempts to repair Disks & clears lots of caches, so if Safe Mode works try again in regular boot.


EtreCheck is a simple little app to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac.

Pastebin is a good place to paste the whole report...

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck.
