I recently purchased some logitech accessories and my computer will not recognize the tiny USB they provided unless I plug it into an additional wire component they provided, thus defeating the purpose of the tiny-forget-about-it-niffty USB. I read that this is because all MACs were switched to 64-bit and supposedly there is a way to convert back and forth between 64-32. Please advise, thanks in advance!

I apologize if I sounds like I don't know what I'm talking about... because its true. – Amy Jul 24 '13 at 19:34
Could you be more specific about what Mac and what Logitech device you have? All Macs since late 2006 are 64-bit, and I really doubt this causes the problem. FWIW I have the Performance Mouse MX with Unifying Receiver and it works without any problems on my 2010 Macbook Pro. – Daniel Beck Jul 24 '13 at 19:38
Here are the instructions for switching modes: – Daniel Beck Jul 24 '13 at 19:41
Of course, I am using the Logitech MK520 mouse and keyboard with unifying usb and my computer is a 2011 MacBook Pro. Thanks so much, I'll give it the college try – Amy Jul 24 '13 at 20:52
Gave it a try and my laptop successfully booted in 32-bit mode but the unifying usb still didn't work when directly plugged into my USB port. Drat, thought that was gonna be the ticket. – Amy Jul 24 '13 at 21:01
