DON'T RUSH is Miss
I know that new
stuff is cool, and double that when it's free, but unless there
is a feature, you need to have, there's no reason to rush into
upgrading to Sierra.
If your system is critical,
then it might be a good idea to hold back on upgrading. After
all, it's not like Sierra is a limited resource. If you don't
upgrade today, it'll still be there when you decide you're ready,
complete with patches and and the typical bug-fixes.
To be honest with you, Sierra is going to really slow down your
computer if it is an older model. Unless there is something you
absolutely need in the new Operating System, I wouldn't upgrade.
You can call me if your aren't sure how old your computer is.
If it is newer, I'd probably give Sierra a while to mature before
Sometimes it is best to slow down to go fast.
