finder not responding...computer screen icon image showing in right corner of finder icon on dock
When I try to force quit finder on my old 2015 MacBook due to it freezing, instead of allowing me to force quite, it gives option to relaunch. When I click on relaunch, finder continues to freeze. When I clicked on the computer screen icon showing in finder's right corner, it opens the Google search page for my newer MacBook Pro laptop. When I say Google search page, it shows the page I recently searched on my new laptop. When I close the lid to my new laptop, this icon disappears. However, the finder still freezes. I had my new laptop lid open because i was looking at something to print from on it on my old laptop which is linked to my printer. Somehow my two laptops got connected together. How do I unconnect them so my Google search is not linked to my old laptop. Also, how do I unfreeze finder to work again. Again, I tried force quit as well as powered off my old laptop, but it doesn't work.
MacBook Pro 13″, macOS 11.2
