Hi there. I have changed my mouse pointer to a large black pointer so it's easy to find and easy to insert into text that I need to edit. However, my pointer changes to a figure that has a line at the top and bottom and joined by a vertical line. I find this very challenging to place in a specific spot to edit text or to close a window. I called Apple Care and they suggested that I reload OS X Yosemite - it made no difference. Is there an expert out there who could assist me in correcting this issue? I would appreciate it very much! Thank you!
