Hi,
I just have downgrade from macOS Sierra for some reasons (performance/buggy) and one of those was sublime.
I don’t know who was the fault, but I’m putting here the problem I had.
When I select some text and then click (on the selected text) to deselect, sometimes it doesn’t happen and I have to click two times or try to click in some other point of the text. Deselection works if I click in some point that is not selected (which is not the case when all selected).
Another problem that I’m having, probably related, if I double click in a word to select, sometimes it puts the cursor at the beginning of the word and others at the end. (Most of the time at the beginning, very annoying for me).
I was using build 3126 on macOS 10.12.1. I remove all packages and it still there, so I rollback to build 3114 and still there.
Now that I removed sierra, all comes back to work again, even with my favorites packages.
Thanks for the awesome editor, and I hope this bug behaviour is related the OS and be solved at 10.12.2 without changing sublime app itself.
