I was downright emotional about it and I received some great suggestions as to how I might resolve it, but since the machine had been upgraded so many times (it literally has not gotten a fresh install since Mountain Lion, yet no performance issues until just now, oddly) I opted for a full install. Unfortunately, as I reported in that other post, it suddenly started suffering from the notorious kernel bloat issue where those familiar processes became the machine's sole purpose as they were generally up top of the proc table as I have seen it on many other troubled Macs in the past. (It was the highest end CPU chipset available - 2.3 GHz - and I maxed out RAM to 16 GB and swapped in a fast SSD with a dual disk kit so it was even at baseline a fantastic machine for the price.) Honestly, it's been faster than even the newer MacBook Pro 15" 2015 I was issued at work- even though its still the 2012 version. Who knows what impact those things were having besides warping the chassis.Īs I mentioned in another post, on my i7 Mini, suddenly had performance issues while running Sierra for a machine that hitherto been a wonderful machine for the 5 years she's been running without hardly ever a beachball. I have long had issues with both Window Manager and kernel_task taking up seemingly inordinate amounts of resources on my systems going back in the OS release cycle for as long as I can remember, but since I had my MacBook Pro 13" i7 back from the shop with a new SSD, screen, and battery, I did a restore from TM and updated it to 10.13.3 and I actually don't even see either WindowManager nor kernel_task running at all! I will add the this machine has performed better than it ever has, this is likely attributed that to the fact that its puffy batteries were replaced.
