comment Very high kernel_task CPU usage after updating to Yosemite 10.10.4
@Tetsujin Thanks, though I would be surprised if it's heat. I had quite some effort to keep it cool in case that was the problem. Thanks though, and maybe you're right... Today and yesterday were cooler. But booting in safe mode didn't cause it, yet the computer was still running the same software (etc Chrome.)

I've had a fan pointing at my laptop for a week now, just in case that was the cause. Thanks though!

It seems to be behaving itself today...

It's occurring for me without the Parallels kexts loaded (they are only loaded when I start Parallels.) Jean-Philippe - I'm glad I'm not the only one seeing this! At least yours was only one hour :)

@patrix Edited to answer, but basically no, nothing. I have some Parallels kexts loaded (Parallels is fully up to date) and batter health of 'check battery' - maybe that could be related?

Thanks @patrix . I've read most or all of those and so far as I can tell none apply. The kext thing is a possibility, but I don't have anything odd installed, so it might be one of the inbuilt drivers (?) - I suspect that especially since this problem was introduced by 10.10.4. I'll investigate those and update, though. Btw, since this was definitely introduced by 10.10.4, is it really "too broad" a question? I've narrowed it down from most things and it's OS-update-specific - that seems quite a specific question to me.

comment MacBook Pro “clicking” while muted when showing a message dialog in Windows on Parallels - what's happening?
hobie - thanks for the answer! As Tetsujin says, can you edit your answer to include the relevant details, please? This site tries to keep knowledge on the site, since links can vanish. (It's quite fine to have a link, just please include the key bits here too.)

Thanks Mike! I still have the problem occasionally, and I'll try out your solution next time it occurs.

comment Spaces in Mavericks: apps do not remember their space
Re the bounty I added, to describe my problem: I have the main space, and to the right, a space for a fullscreen Parallels instance, and to the right of that, a space for Mail. However, Mail always opens 1 to the right of the main space (not 2), and Parallels always opens to the right of Mail, instead of in between the main space and Mail space. This is in spite of rearranging the spaces. Mavericks does not have the "Assign to..." dock menu item, and apps do not appear to remember their last assigned space. "Automatically rearrange spaces" is turned off.
