Failed to connect to consoleX - causes scrolling to hang for 3-5 seconds

Bump.

Found this thread when searching the console error. Having the same issue. Has anyone found a solution?

Thanks.

Hello

FYI, I have same error messages with El Capitan.

So my guess is that Apple has not fixed it yet ... and doesn't seem to care about it.

MacPro 2013

I'm getting this same error in Yosemite (10.10.5). We can only commiserate with each other... It doesn't look like Apple cares. But this is just one of MANY bugs I've encountered: )1 Snap-to-Grid doesn't work right. 2) Many "alias" icons on my Desktop are NOT correct. 3) I can't completely "turn off" the keyboard back light.. The minimum time is 5 seconds. 4) I miss "ipfw" for setting up Firewall. 5) Many Applescript applications now fail because of "UI elements". I had to resort to Automator (Run Applescript) and drop the application into the Privacy->Accessibility window. Very annoying. And the list goes on....

I have been having this same problem, but I believe only since 10.10.4.

"Console[1174]: Failed to connect (_consoleX) outlet from (NSApplication) to (ConsoleX): missing setter or instance variable"

Does anyone have any information to try and mail down what is causing this? Do you guys all have Dropbox? I'm on a Mac Pro.

I would really like to see this resolved -- frequent spinning beach balls and complete system hangs are NOT fun.

I am using Macbook Pro 13 Mid 2014. I have the same exact problem. Everything with graphical start lagging when I check console I saw the same error log. OS is El Capitan.

We have 3 MBP's 2015's and all have the same issue with El Cap!

I notice this problem frequently (but not alway) when I first open Gmail. Started with Chrome...recently switched to Safari and seemed good for a few days - now doing the same thing with Safari. Open Gmail, click on a message to either open or delete, and get just get loading message. Check console and this message is always there when this happens. This is on a six month old iMac running El Capitan 10.11.2. However, does not happen on my MBP that is a 2011 unit running the same OS.

Suggestions appreciated.

Did anyone ever figure out how to fix this? Almost every action causes a 2-3 second delay. It started after I added a Firmware password and changing my login password. That's it. Verifying/Repairing permissions didn't help, new users have the same problem and reinstalling the OS isn't an option.

Reinstalling doesn't work at all problem is still there. What is Apple doing!? They must experience the same problem, but where is the fix? They are becoming more arrogant towards their users. We pay a lot of money and don't won't a laggy OS X experience!

I am having this issue as well.

I guess no one has found a solution or cause?

Nah, ended up reinstalling the OS and it's all good now.

I don't think the ConsoleX error caused the issue though. I have another Macbook for work and I see the same error popping up in the Console for a while now, but the computer runs buttery smooth.

I have the same message: "Console[517]: Failed to connect (_consoleX) outlet from (NSApplication) to (ConsoleX): missing setter or instance variable".

I have received two additional and very SIMILAR messages when running the Console Utility:

"com.apple.WebKit.Plugin.64[520]: Failed to connect (colorGridView) outlet from (NSApplication) to (NSColorPickerGridView): missing setter or instance variable"

AND

"com.apple.WebKit.Plugin.64[520]: Failed to connect (view) outlet from (NSApplication) to (NSColorPickerGridView): missing setter or instance variable"

I have the idea that the problem is inside NSApplication. I have the idea that NSApplication failed to "connect an outlet" FROM NSApplication because NSApplication failed to provide a "setter or instance variable" TO ConsoleX (or to NSColorPickerGridView).

I have no method and no idea to fix this !!

Still no solution and this issue still happening to me too.
