I have an issue on my MacBook Pro (15-inch, mid 2010, macOS Sierra).
Some applications won't open, or don't work as expected, and generally I see the spinning pinwheel and macOS is really slow.
Also, often when I shut down I see a black screen, but not completely turned off, so I have to shut down by pressing the power button for 3-4 seconds.
Sometimes applications like Google Chrome or Final Cut Pro don't work well, often freezing up or not opening.
But all these issues disappear if I boot up in safe mode (applications work well, restarting and shutdown always work, no frozen apps, etc).
I tried to:
- follow the guidelined to isolate the issue on this article: https://support.apple.com/en-us/HT201262 but I don't have any login items.
- create a new user profile, but the issue isn't fixed.
My question is: What differences are there between safe mode and standard mode? What can I disable to isolate the issue?
