Howdy everyone I have a really annoying problem. I can bootup fine no problems, however after I click on my profile picture and login, it will randomly hang on a grey screen for about 10 minutes, before successfully finishing the login process. No idea what causes it but it's happening a few times a week. Seems to also be correlated with another wake/clamshell/thunderbolt issue. I'm technical and would love to know if there is a good strategy for troubleshooting these sort of issues.
