Ball Joint Replacement (Mac only)

If you're mounting a heavy Mac monitor on the Humanscale M8, Humanscale recommends adding this optional ball joint replacement for Mac monitors, which will keep heavier Apple monitors from tilting down. Please note: Because this is not a ball joint, this part does not allow tilting at the end joint. Mac monitors also require an Apple proprietary product called a VESA Mount Adapter Kit to work with any monitor arm. The Apple VESA adapter kit is only available for purchase from Apple.

M8 dual monitor arm
June 20, 2013
On the plus side, this beats having two separate monitors sitting on the desk top hands down. The arm is a little stiffer to operate than I would like, the pivots on the arm are just not smooth. Perhaps disassembling and using some teflon tool lubricant would do the trick, but that's more effort for something that shouldn't be an issue. My biggest complaint is that the two monitors, which I have keystoned, do not easily stay aligned with each other when I move the arm from one position to another. I have a sitting and treadmill position on this desk, and getting everything set just right takes far more effort than is should. There should be some mechanism to bind the two monitors together, like velcro strips with pressure sensitive adhesive. I consider this aspect a significant design flaw.
