I Just Updated to MacOS Sierra
 

The feature that got finally got me?

The ability to double tap the space bar and put a . at the end of a sentence...like on my phone.

I constantly do it on my desktop and laptop. At least one will work now.

One thing I noticed: After I upgraded, my computer was running slow for a day. I thought it was permanent but its not. It's just spotlight doing some reindexing. Once it finishes, your computer runs fast.

My desktops are Hackintosh units I built. If this MBP upgrade goes as it should, I will start migrating those too.

But yeah, the double space bar to . is only thing that spurred me to update. Though I could have set it up with something like TextExpander, but whatever...

i still wait one or two months more before to upgrade

That was my thinking too, until I double tapped my space bar once again this morning and there as no . at the end of my sentence. :1orglaugh
