'ioreg' Process hogging CPU

Question

Over the past 2 months since being dislocated from moving and not being able to use my iMac as my main computer, I've been using my Macbook Pro. Lately, it's been getting slower and slower each day, and I often have apps crash or have the spinning ball lots of times during the day for simple tasks such as copy-and-pasting, closing tabs, etc.
Today I looked at Activity Monitor and saw a process named ioreg taking 99% (maxed at 101.5) CPU capacity, and it's a process that just won't go away permanently (assuming it has something to do with the OS). Is there anyway I can fix this process to where it doesn't completely take up all of that CPU %?

Answer 1

Does the its parent process (being "launchd", owned by root) give us any other clues?Not lot. Since 10.4, launchd has become the first process created by the kernel on startup, replacing init, so ultimately it is the parent of everything. But it does mean the process is started independent of any logged-in user.
Many processes, even those directly owned by launchd, are only "launched on demand, but this is controlled by a .plist in one of the "LaunchAgents" (for logged in user tasks) or "LaunchDaemons" (irrespective of logged in users) directories in /System/Library or /Library.
I cannot find any reference to "makequeues" in those folders, so lets do some detective work:
Open the Terminal (from /Applications/Utilities) and copy and paste the following into the Terminal window, one line at a time, with a return after each line:
launchctl list
sudo launchctl listAfter the second command, you will be prompted for your password. This is not echoed for security reasons: just type it and press return.
If you haven't used 'sudo' before, you will receive a little lecture before being prompted for the password. Read it and continue
Copy and paste all of the output (include your commands) and post it here. You can type exit to get out of being root.
The first command will very likely produce no output, unless you have login items. The second should list all daemons started by launchd as root
