spinning beach ball!
My circa 2013 MacBook Pro is displaying mostly spinning beach balls.
I tried to reboot. It took a lot of time-- approximately 50+ minutes to go from white loading screen to password screen.
Spinning beach balls almost constant, I managed to eventually sign in with password and to force quit all of the open apps, shut down, and reboot.
Still so sluggish with almost constant spinning beach balls. What could be wrong? Is this a sign that the hard drive is about fail? Is it a sign that I need to update my OS? I have resisted updating my OS because in the past updating would usually result in a problem-- for instance, not being able to use all my apps, etc.
I was able to successfully run Apple Diagnostics over the Internet by holding down Option-D at startup. No issues were found.
What should I do? Update the OS? Is there a way to check the hard drive to make sure it is working optimally? Help, please!
