I didn't install Mavericks. I doubt the power saving technology wouldn't cause any performance issue, so I'm still waiting.
But I just found this interesting thread. Several users got their MBP's work like a charm.
I'm just not seeing any benefit to "upgrading" to Mavericks.
Complete drop of third party media formats (Gee THANKS Apple)....reduced performance....flakey stability...all for what? Tags etc? NO thank you!
I downgraded to Mountain Lion via my Time Capsule and ALL of the issues went away.
So, How is Mavericks better?
I find it faster. On all my Macs. Others have it show up all the third party rubbish they have carried over from older OSXs. If you are running an older OSX you will need to post in the appropriat forum. You an also use Google if you wish. Or search these threads. Your question has been answered over many times before. Also stop thread jumping and open your own thread as you have gone off topic.
Everyone should understand that petermac87 can't stand that many of us are experiencing much slower Macs with OS 10.9. If doing nothing but upgrading to Mavericks caused our Macs to run much slower, than something is different in Mavericks from OS 10.8 and 10.7 that is causing it.
I removed every app that a few people on this thread suggested might be causing the slowdown, and nothing changed.
Joe, the point is that many people have old software that is causing these issues. Did you use EtreCheck or System Profiler or something else to see what was installed & actively running on your system?
It's likly that the combination of installed software is specific to your Mac, so following the recommendations may not get everything that can be slowing your Mac. Post a new thread with a system report if you want to be sure nothing is actually left running. It also helps if you describe the symptoms.
Yes, I used EtreCheck and removed all of the Apps some of you thought might be a problem (I really spent some time doing this). I did not see any difference. I did post my final EtreCheck on a separate thread, but I don't think I got any replies.
The combination of installed software may be specific to my Mac, but it is quite clear to me that under OS 10.7 and 10.8, my Mac ran faster than it does now after upgrading to 10.9. So something in 10.9 is different than the previous OS's. If Apple made Mavericks much more sensitive than 10.7 and 10.8 to something(s), it sure would be helpful if they gave us a general list.
My symptoms are at startup; startup of the computer and of any app. That is, when I start my Mac Pro (2008), after the screen finishes displaying everything, it "freezes" with a lot of disc thrashing. Under 10.7 and 10.8, this happened and lasted perhaps a 5 seconds. With 10.9, it lasts about 30-60 seconds. This "disc thrashing and computer freezing" also happens when I launch any app. For example, under 10.7 and 10.8, when I launched iPhoto, after it displays the photos, it would take about 5 seconds before it would respond to anything (I always thought it was Faces doing its thing). With 10.9, it now takes about 30+ seconds before iPhoto will respond to any mouse directions. Once an app is running, it seems to run about the same as always.
This "disc thrashing and freezing" happens when launching any app (e.g., Word, iMovie, etc.) This has slowed down my efficiency a lot since I am starting and quitting apps often.
I did check you profile eariler Joe & I couldn't see a report which is what compelled me to ask. That might explain why you got no replies!
Your symptoms need to go in a new thread if you want to troubleshoot it.
Obviously it would be a good idea to verify & repair the boot disk in recovery mode (back up first) because disk thrashing could be a sign of a disk in distress.
I have two macs, upgraded both, and one was noticably faster while the other was significantly slower. I've tried several things to try and resolve it, without much luck. Or rather, doing anything that requires a reboot seems to resolve it until enough time passes and/or the computer has been asleep and reawakened, and the performance problem came back. It seemed pretty clearly related to memory, as I could get a temporary performance boost back by exiting memory-hog applications.
Finally, I disabled Speech and Dictation support which was only enabled on the slow mac. That seems to have solved the problem.
Mavericks is rubbish. Apple have done nothing to sort out the bugs and as usual their arrogant approach is "take it or leave it"
We pay a lot of money for their machines and when they have these upgrades they should be checked properly instead of them leaving us to sort out the problems by reinstalling and wasting our time and money.
Instead of ranting, raving and whining, why don't you start a new thread discussion and post your Mavericks performance issues, so more experienced contributors can help you sort out your Mac issues.
Most problems with Mavericks start with users installing needless antivirus software, crap "cleaning" and "tune-up" style software that isn't needed and can cause performance issues, Mavericks incompatible, non-updated third party hardware drivers and third party software.
Obviously, you are not interested in getting legitimate help to improve your Mac on Mavericks
You rather blame others and Apple for your Mac issues with their new software.
I have a 4 year old iMac that is running great on Mavericks! This software runs much better than I thought it would on my Mac!
