I only managed to do so with the Razer mice. The problem goes away when I change the setting called "USB polling rate" in the mouse driver to 125 Mhz. Note that I did not use the 3rd party drivers supplied with those mice. It appeared with the following mice: Logitech G5 (first edition), Logitech G5 (second edition), Logitech MX620, Razer DeathAdder 3G, Microsoft Sidewinder. The problem is not limited to a particular mouse model or manufacturer/producer.
I can certainly confirm that the problem exists on Mac OS X 10.5 (any version) and Mac OS X 10.6 (any version). The problem is not software-dependent either: it can be reproduced on a fresh system with no 3rd party software installed. The problem is not hardware-dependent: it can be reproduced on all Intel Macs. The cursor randomly jumped for a few pixels from time to time. Move the pointer slowly across the screen
Connect a mouse, such as Logitech G5 or Razer DeathAdder 3G to a MacĢ. The pointer jumps randomly for a few pixels when a high-precision mouse is used.ġ. Problem Report Title: Cursor jumps randomly when high-precision mouse is used They give a detailed explanation on what do these fields mean if you click “description format” link above the text field.įor the above problem, my own bug report was: Apple advises to use the following template: Obviously you need to select “Problem:” Mac OS X, version/build number - whatever Mac OS X you use, classification: “serious bug” or “ui/usability”. I agree, however, that it won’t hurt to fill a bug report.Īfter logging in to the Bug Report, find the button “New problem”. Personally I hate it as well, but frankly speaking it is not a bug. Hello Adam, this particular bug has nothing to do with Mac OS X mouse acceleration. On the opposite, on snow Leopard, when you move the mouse rapidly, the curve is made with segments On XP, when you move the mouse rapidly, the drawing remains smooth.
For example, I tried to make drawing curves with the same mouse on Paint on XP, and Paintbrush on Snow Leopard ( It is nearly the same softwares ). The first one concerns the bad acceleration curves of OSX, and the second one the bad USB polling rate. But even that, is not good enough.Īs far I am concerned, I think that there is 2 issues. The best walkaround for me, is using a Microsoft Standard USB Mouse with ControllerMate and a custom acceleration curve ( like in Microsoft XP ). I use my Macbook every day at work, and I feel very uncomfortable: I can’t use my wrist anymore in the evening. I tried different mouses, different OS ( 10.4, 10.5 and 10.6 ), different hardwares ( iMac 20, Macbook unibody, Imac 27 ), different softwares ( steerMouse, USB Overdrive, ControllerMate ) but no way ! Since 2007 and my first iMac, I unsuccessfully looked for a method to resolve this mouse issue.
