HI all if you who have the question with the i to I problem that Mavericks gives you.
I used to have snow leopard it stopped with Mountain Lion and then I used the i to I rule in keyboard preferences. Because iOS devices do this on auto and mac's don't so I was upset then I made the rule same with a"m"d with and i just typed quick and I like it. When I upgraded from Mountain Lion to Mavericks the rule vanished, I had a problem when I upgraded to Mountain Lion when I would use the letter "i" It would auto move my text around and I know that sounds odd but I called Apple Care and told them what was going wrong and they wanted a video of it so I took a video of it and wow it was sent off to apple.
There response to this was long I still have all the emails this is what was told to me
"That is funny. I started having the same problem on my workstation after we
talked last week and I was thinking, 'how crazy, I now have the issue I was
troubleshooting!" Well, guess what? When you mentioned the i -> I text
expansion, I thought it was a good idea and added it to my preferences. Good
job catching that, I will report this to Engineering."
The Follow up to this issue was,
"I believe the 10.8.3 update (available now) resolves this issue. I have
installed it and cannot reproduce the original behaviour. Let me know if it
does so for you as well."
In 10.8.3 they removed that bug that was causing text to jump around when you would type "i" instead if "I".
So I hope that this answers your questions and yes I still wish we had an i -> I text replacement option just like ALL iOS devices.
