R 3.4.1 Console Interface Very Slow on Mac : <p>I have upgraded R from 3.3.3 to 3.4.1 and am finding that typing text directly into the R Console quickly becomes very laggy, even when R isn't using a lot of resources. I have observed this behavior running the last couple versions of macos sierra (10.12.6, etc.).</p>

<p>It is notable that R functions are not particularly slow when executed. Most of the time I use Textmate 2 to pass code to the console and the code passed in this fashion runs without delay.</p>

<p>I've done extensive searching, but I haven't found anyone else reporting this problem. I've found this behavior on two different macs: 2013 Macbook 13" and 2017 Macbook 15" and have encountered the same problem.</p>

<p>Is there an easy solution to this problem that I'm missing?</p>
