I'm trying to clean up my very old MacBook Pro before getting a new one. I don't want all the extra and duplicate items on a new one. I upgraded to Sierra so that i can "Manage" the Storage.
It has been quite slow for a while and I wonder if there is any way to speed things up.
You are getting rid of it, and now you want to speed it up...
I would be suspect a 2010 with the original OEM HD that the drive itself could be failing.
You can run the utility http://etrecheck.com
to get a good look at your System conf. for conflicts/errors/ failures/ malware etc
you can post the results in the additional txt box if you need more help interpreting the output:
