Q: KVM Mouse Buttons Fail after Yosemite Upgrade

I have several computers attached to an Avocent 8030 IP KVM. Prior to upgrading to Yosemite from Mavericks, the KVM worked flawlessly. After upgrading to Yosemite, I have location control, but no mouse button click control through the KVM. I have been able to reproduce on three systems. The first was a current model Mac Pro, the second was a mid-2010 Macbook Pro. Both worked previously but now do not. I have an existing last-gen i7 Mini that hasn't been upgraded and still works when plugged in with the same dongle and port.

 

Has anyone else seen this behavior with a KVM? My assumption is that the OS is handling third-party mice differently in this version. I'm hoping there is a setting I can change on the Mac side to restore the previous behavior.

Mac Pro, OS X Yosemite (10.10)

    A few days ago I did a clean install of Yosemite on my MacBook Air 13" (2012).

    Since this upgrade I get regularly the spining beachball of death (total freeze) while I have my ATEN CS682 KVM attached to one of the USB ports.

    If it is not attached, then I don't have any problems.

    Also before upgrading everything worked fine with KVM attached.

     

    As it seems now I will have to downgrade. Or does anybody know how to fix this?

    Also having this issue - on a brand new KVM. Works on all other OS's when this occurs.

    I have a similar problem; Belkin SOHO 4-port KVM. My microsoft trackball works fine when plugged directly into my (new!) MacBook Pro Retina USB port, but only works briefly when plugged in through the KVM. I tried rebooting with it present, absent, every combination I could think of and the most I got was a couple of seconds of mouse movement before it ignored everything done with the trackball. The keyboard behind this KVM works fine; it's only the trackball which doesn't work - and I verified the trackball is still working with my other machines through this KVM. Oh, and it works fine with my older MacBook Pro, running Mavericks.

     

    I'm almost at the point of going into the office to haul out my USB analyzer and see if I can figure what MacOS is doing wrong.

    I have two late 2012 Mac Mini's that I have connected to a USB keyboard and mouse through a cheap mechanical USB switch. I upgraded both to Yosemite. Whether I switch or not, the mouse clicks quit working at some point during a session. It seems that if I let the system go into a sleep mode, it always happens when it wakes.

    I am having the exact same problem with an Avocent AutoView 2020.  The mouse buttons worked before the upgrade and they work on Windows, Linux and  Mavericks OSX systems on the same KVM but not on the newly upgraded Yosemite Mac Pro.  If I unplug the mouse from the KVM and plug it directly into the Mac Pro it works.  The same mouse through the KVM and the buttons and scroll wheel do not but I do get a mouse cursor and can control its movement.  Very strange.

     

    I sure wish there was a fix for this.

     

    Anyone out there listening?  I am sure a lot of people are experiencing this problem.

    I called Apple Support on this and they said it is a known issue with no fix or workaround at this time.  The mouse click and scroll apparently do no work going through any KVM.  They are working on a fix but it won't come out until 10.10.2 comes out.

     

    So, if you are using a KVM it is best not upgrade to Yosemite just yet unless you are willing to hook up a separate mouse for each Mac you have going through the KVM.

    Can anybody confirm that 10.10.2 resolve the issues with KVM?

    Sadly, no it does not look like the 10.10.2. update fixed the KVM problem at all.  At least not in my case.  Really no excuse for this type of flub up and I think it is very damaging to Apple's reputation of having an operating system that "just works."  They are looking more like Microsoft every day.

    Really bad!

    I was looking forward to buy a new MacBook Air when the new model arrives in the next months… But with this situation… I think we can expect that the new Airs have the same issue and we cannot downgrade new MacBooks models to an older OS-X version (like 10.9), or can we?

    It is unbelievably ridicules that this problem has continued unresolved for this long.  I wish someone at Apple was paying attention and realizing that people are holding off upgrading because they access the host through a KVM.  Not just home users but enterprise users has well.  Not keeping systems up-to-date posses a significant security risk to those systems.

     

    IT IS IRRESPONSIBLE ON THE PART OF APPLE THAT THIS ISSUE HAS NOT BEEN ADDRESSED.  INEXCUSABLE!!! 

     

    IF MORE PEOPLE SPEAK UP MAYBE SOMETHING WILL BE DONE.

    Well, any hope that the 10.10.3 update would fix this just got dashed.  I ran the update.  Had to clear the NVRAM so it would boot again (Command-Option-P-R).  But still no functional mouse clicking through the KVM.  Absolutely ridicules!

    I also have this problem. Has anyone heard back from Apple and when they will fix it? Will it be fixed in 10.10.4?

    Just upgraded to 10.10.4 and it did not resolve the issue.

    I gave up on this some time ago. Has anyone found a fix or work around short of replacing the KVM?
