Hi Albert,

Are you running macOS Sierra 10.12.1 the most current version ?

It is always a good idea to run Apple's Disk Utility to repair the hard drive on a regular basis. Click on First Aid and then click on Run.

In addition it's well worth the money to purchase Disk Warrior 5 ( http://www.alsoft.com/DiskWarrior/ ).

A couple of quick solutions to help a sluggish Finder is to restart your Mac or Start up in safe mode

To start up in safe mode:

Start or restart your Mac, then immediately press and hold the Shift key.
To leave safe mode, restart your Mac without pressing any keys during startup.

What is safe mode?

Safe mode (sometimes called safe boot) is a way to start up your Mac so that it performs certain checks and prevents some software from automatically loading or opening. Starting your Mac in safe mode does the following:

Verifies your startup disk and attempts to repair directory issues, if needed
Loads only required kernel extensions
Prevents Startup Items and Login Items from opening automatically
Disables user-installed fonts
Deletes font caches, kernel cache, and other system cache files

Together, these changes can help resolve or isolate issues related to your startup disk.


I find that it is better to not load ( that is run ) too many applications at the same time. Which means if i want to work with Band in a Box ( plus the plug-ins ) then that's all i run: just Band in a Box. My iMac has 12 GB RAM.


Hope this helps you. Let us know how you make out with your sluggish Finder.
