One quick fix to try: stop applications from loading automatically at login. Right click on a launcher item / program you'd like to stop from automatically launching upon login/startup Click Options Click (to uncheck) Open at Login This prevents programs from taking up RAM that can be used for applications you actually care to run. One other thing: ...

Two monitors, transparency off. I've have trouble with horribly laggy control-magic mouse zooming since updating to Yosemite. Sometimes it'll take as much as 5 seconds for a simple screen zoom to complete. Trying to de-zoom while the Mac is off doing it's zoom thing sometimes just adds to the problem. Monitor level zoom is much better behaved if I set ...

You're going to have to broaden your search. There's nothing in your screenshots that points to Terminal. Nor anything in my experience—I let Terminal run for days with no ill effect. It's possible that you're starting some task that's running away with the processor. You could set Activity Monitor to show all processes hierarchically, and give the tasks ...

CrashPlan Tray is definitely one culprit for high CPU usage. It helps to disable animations in the tray preferences. But it still did not solve the problem for me. The only thing that solves it for perhaps a week seems to be a full reboot. After that the machine simply becomes sluggish, and needs to be rebooted. Back to Windows95 yay! Apple should do ...

First of all it's probably a good idea to stop using that memory cleaner app. They aren't necessary these days; if they ever were. The memory systems on modern operating systems are perfectly capable of maintaining themselves. The way these memory cleaner application work is by claiming a huge chunk of RAM, thereby forcing everything not critical out of RAM, ...

First, Chrome uses a lot of memory, especially if you have had it open several days. Usually closing apps helps recover and frees portions of memory, but still keeps some for the very same reason RAM is used. After closing you're apps, you can purge command in your terminal to force disk cache to be purged (flushed and emptied). sudo purge Enter your ...

Upgrading to Yosemite did make things quite a bit better. It's still a bit sluggish sometimes, but overall response times are much better. Also, the spotlight indexing took quite a hit.

The problems were resolved by Apple servicing the hardware.

Onyx is a great app to help you clear out a lot of the clutter you may have accumulated over the years and speed you up a bit. Be careful though, it's a powerful tool so make sure you know what you're doing with it before you do anything. As for boot time, make sure you don't have a lot of daemons loading at launch. One easy way to check is to go to System ...

Try running Yasu, it's a free Mac app that cleans out system caches and runs maintenance scripts. It sure did help speed up my 2010 iMac when it started running slow.

Originally posted 20141207 on ViktorPetersson.com I found my model number plist file in: /usr/share/pmenergy/MacBookPro11,1.plist but left it there pending my swiftly-approaching Apple Store visit. I had to struggle to keep the Mac Geniuses on the subject of kernel_task but once I did that, they came up with the following solution. That was yesterday. So ...

I noticed your post. I've upgraded my main production hdd up to yosemite a little early. I ended up running mavericks from an external drive and accessing yosemite just for files as the hdd is still inside my macPro. Now I am booted back up to yosemite as it is getting updates and acting a little better (slowly). So some things are working better, but i am ...

One way to accomplish this would be to test the performance in a virtual machine configured to represent a more limited processor. Assuming you're using a Mac which came with a pre-installed OS, you'll probably need to buy an additional Mac OS license, but the virtualization can be done for free with VirtualBox, or for a moderate cost with Parallels or ...

I deleted my old answer since it had turned out to be only a temporary fix (if even a fix at all). Today I found something that cleared up most of the slowness for me which I describe in detail in this link: Yosemite: Accessibility zoom + multiple monitors = poor performance Somehow my user preference file, com.apple.sidebarlists.plist, had acquired ...

After upgrading to Yosemite I've also been getting extremely slow response in a number of different situations such as long pauses for Spotlight to return file matches, slow start up of applications especially after waking from Display Sleep, as well as other operations. (It feels like walking in quicksand and finding you can't move like you could.) Also, ...

Take the resolution down. Remember that the rMBPs have a native resolution that is way higher than 1080p, and expecting them to game at that resolution is perhaps expecting too much. I use a 2014 13" rMBP (which uses Intel Iris, not an external Nvidia card), and I rarely have any issues running RoS at 1280x80x60 with textures to high and other settings to ...
