i've just "upgraded" to sierra and whenever i separate a tab from a finder window, a small folder icon appears on the desktop. sometimes it floats on top of other windows - see attached. it's really annoying - especially since i turned off automatically creating tabs instead of folder windows...
I was set to get the IPAD Pro 9.7 even with 2GB ram but my plan got halted after watching this youtube video showing how much better the IPAD Pro 12.9 with 4GB ram was against the Air2 with 2GB ram.
I use my IPAD for Email, youtube, facebook but mainly for browsing and I open a LOT of tabs...
After updating to El Cap 10.11.3 from Yose: Switching between tabs in Safari or Finder doesn't work using Ctrl+Tab. It works only for switching between tool buttons. In Chrome and Firefox it still works as before. Have had this problem before upon updating major versions.
