Late (final?) era Intel iMac.
I would like a Shaman, Holy Man, or, maybe, a Witch Physician. The Ghost in my machine is combating again.
In abstract, my mouse “goes silly”.
What does that imply?
It means it appears to be sending rogue mouse clicks, mouse clicks to locations that aren’t beneath the pointer, mouse clicks once I kind the house bar on my keyboard. As with all issues of this nature, it may be intermittent.
This occurs with my Bluetooth keyboard. It occurs with my USB keyboard. It occurs with my BT Mouse, and my MS Wi-fi Mouse that chats with a USB dongle.
I’ve eliminated all of my USB Hubs, all of my exterior USB drives. It is only a uncooked iMac, working a contemporary Sequoia. I upgraded to Sequoia on the off likelihood that may do something.
I’ve eliminated the Logi Software program for my BT mouse and keyboard. I am presently on my Apple USB keyboard and MS mouse (pink, with flowers on it).
Lately, after the Sequoia set up (and by Set up I imply it was an inplace set up over my Large Sur, I didn’t wipe the machine and reload from Time Machine, I do not know if that may be completely different or not), it has been secure. Previous two days, its gone out to lunch once more.
When a restart does repair it, it needs to be an influence down chilly boot, a logout, or restart would not repair it. I’ve to energy off first.
A method I can inform the enter system is “sick” is once you go to an functions menu bar, click on on a menu, and drag the mouse down. Usually, the menu entries will spotlight. That doesn’t occur when the system is sick.
Different issues are, as I discussed, mouse clicks not registered (at the very least not the place the mouse is pointed). Random mouse clicks. You may hover the mouse over one thing like, say, a hyperlink in Safari, and subsequent factor you understand I’ve 5 tabs of no matter that hyperlink linked to open.
The enjoyable one is the spacebar. A easy instance is a textual content entry field (like this one). Each time I’d hit the spacebar, a mouseclick can be despatched. So, think about the mouse on the identical line because the textual content you are getting into, say, 30% from the left hand margin. As you begin to kind, all is nicely till you cross the brink of the mouse. Then, every time you hit house, the mouse clicks, the caret is now reset to beneath the mouse, and also you’re typing in the course of your sentence. Good instances.
I’ve to consciously hold the mouse in a “secure place”.
I need assistance diagnosing this. I don’t know how one can proceed. Although I’ve eliminated the entire USB stuff on my pc, I do not truly assume it is a USB downside, contemplating it manifests of Bluetooth as nicely. So it should be one thing else.
I’ve reset the parameter RAM, I’ve accomplished different issues (that I do not bear in mind to be trustworthy), but it surely’s all been fairly deep, arcane stuff.
I do not know if I can grasp a dtrace off of one thing that may maybe spotlight displaying the rogue system inputs. Not that it will repair it, however perhaps it will give me extra knowledge.
I’ve not seeing any gross, apparent errors within the logs (however the logs are legion in dimension, in order that might not be saying something). I do not know if USB and BT are unified internally into the identical peripheral system system, and one thing is incorrect with that. At this level I am guessing it is a {hardware} downside (and woe is me whether it is, me thinks, it is an iMac with one shifting half).
Any perception appreciated.
