Yosemite slowing down Macbook Pro

I am so disappointed with Apple. I spent over $1200 on my macbook in order to avoid problems with terrible software and now they release Yosemite which has caused nothing but performance issues. I've read all of the forums and followed all recommended steps to "speed up my system". I didn't have any issues with speed prior to ....hmmmm.

All I can say is that I hope Apple releases updates to Yosemite right away that will fix the issues causing systems to slow down. Otherwise I'mg going to have to dump this and get a different computer. It won't be a mac if I can't count on them anymore.

I ended up using MacCleanup2 and bought the package. It ended up freeing up over 18 GB of space on the drive while of course eliminating all of my browser history. But I expected that. A pain, but the sites I use will rebuild again.

Repaired Disc Permissions. There was a ton of garbage in there. However I just repaired it a couple months ago and it had rebuilt to a rather large level again. Have not reset SMC as yet and I think I will wait to do that to see how permanent the speed increases are with the actions taken so far.

I can completely relate to the slow cursor problems and all they entail. Points out how nasty things can get when the memory is running on empty and there is no relief for it even when it tries to dip into other resources.

I think that is the biggest problem I have seen with Yosemite. The browsers continue to eat up more and more memory the longer you leave pages up and running and the longer the time between restarts. 'This has always been true to some extent. But I have never seen it as bad as it is with Yosemite. As some users have mentioned, their computers are sucking down tons of memory while doing nothing...I assume that means no web sites open.

While it is nice to see the computer return to some semblance of normalcy at least for now, the computer already had all of that garbage I just cleaned out on it before installing Yosemite and it was for all intents and purposes running fine...not nearly as buggy, nervous, sluggish and problematic as it has been with Yosemite. There are times when it almost seems to have developed a nervous tick with Yosemite as the OS......very unstable.

I have the Activity Monitor up in front of me full time now. I want to see what happens over the course of a few days. What has happened is that something like Firefox will just absorb more and more memory to the point where it just races past everything else to the head of the line and will be eating up as much as 3 GB of memory of the total 8 that the machine has. Again, I don't think every one of these machines is suffering from browser related memory issues but I feel fairly certain that they are mostly memory related issues. Some programs and functions that seemed well controlled with every OS up to Yosemite seem to be running amok with Yosemite. I would recommend that if you have been able to get your machine back to some sort of normalcy that you keep the Activity Monitor up for a period of time and see what happens. Just because we may be able to get these machines back to some decent state does not mean the problems have been resolved. I still think there is something embedded in Yosemite that has your computer sucking down tons of memory with the process accelerating the longer you go between restarts of the computer.

So, went away from the computer for a couple hours. Came back...while doing nothing memory usage climbing steadily the whole time apparently.

So I decided to take another step and reset SMC. Just did it. Not sure if it will do anything. There just seems no way to stop memory usage from climbing at an unreasonable rate while the computer is on. It no longer takes a few days to climb....seeming a few hours and your memory is bumping the limit even if doing nothing for that period of time.

Well SMC has not slowed down the memory leakage one bit. The kernal_task and Firefox grow unabated. I can sit and do nothing at the keyboard and just watch them suck away memory until memory is maxed out. The fan kicks on and another GB gets sucked away. Any idea what I should try next?

So what do I do if I can't past my Etrecheck report here for review. I can get the report to my clipboard but I can't do anything with it from there. Kernel_task seems to be sucking away Memory at an alarming rate. But I can't paste the report here to get help. Nothing is allowed. Any ideas?

Now that time has passed and several updates have been issued, are you still experiencing slow-downs?
