After installing the lightroom 4 on my new Imac 27', I found the font are too small to read. I can only change the font size of menu a little bigger and can't do anything about the other font size. I am so frustrated. The reason why I bought Imac 27" is to protect my weak vision and there are no means to change the font size in lightroom. I searched online and found many customers had this issue. Is there any solutions?
