High Sierra slow login with new macbook pro

Hi there,

Here a newbie, that acquired a MacBook Pro one week ago.

I set all the computer, using OS Sierra and was astounding with the laptop speed.

Then update to OS High Sierra at the unexpected expense of the login time.

It seems like an old machine. Just in the login, for the rest performance was not affected.

As a regular windows user, I decided to perform a clean install.

Nevertheless, with some outcome.

Thus, I am disappointed with my new MacBook Pro. It seems an old machine during the login.

See the video: https://youtu.be/TMnECfme5do.

Already tried some solutions, e.g. high sierra slow login.

Without success.

I do not have any programs during start-up, only finder.

As I want to start to use my laptop for work, my question is:

Should I downgrade to Sierra and admit my computer, despite new, is unable to perform a fast login with High Sierra. Or there some solution for this issue.

Thank you for helping a newbie mac user.

Kind regards,

João Soares
