Mac slow after installing Maverick

Hi,


as others are reporting, I've got a lot of lag on my Mac after installing Maverick. I have to keep waiting for things to happen (it's like using my little Windows laptop!!). Especially Chrome shows this behaviour and Mail. When I switch to the application or open a tab it takes ages for it to render. There seems to be a lot more (audible) harddrive activity.

Can I, shouldI reistall Mavericks now that MacKleener is gone? Computer is acting like its haunted. The Timemachine clock does not move while backing up, the video controls do not respond in the middle of watching something and Word just hung while it was in the background??? thanks If so, do I just go to the app store and choose it or do i have to do something different now that its already running? thanks!!!

I certainly found it useful early in my use of Mavericks and I know plenty of other users who solved their own mysteries by re-installing from the Recovery HD partition. You might be able to get away with just downloading and installing the OS X 10.9.2 Combo Update.

The Timemachine clock does not move while backing up

The one in the menu bar no longer does that in Mavericks. The arrowhead doubles when it's running, but no more rotation. If you have your TM volume shown in the sidebar, there should be double-arrow rotation there.

do I just go to the app store and choose it or do i have to do something different now that its already running?

For those who still have this problem, this is the solution:


1 - Start the mac holding 'option';

2 - Choose the recovery boot disc;

3 - Select Disc Utility option;

4 - Select the disc where os x is installed;

5 - Click 'Fix disc permissions' button;

6 - Wait till it's done;

7 - Restart you mac in normal mode;

8 - Problem solved (At least for me and the guy that told me to do this).

I believe that all the problems that people are reporting in this thread stem from installing Mavericks over a previous install of OS X (the way Apple wants you to do it). I had major problems with my MacBook after installing Mavericks over Mountain Lion. You need bite the bullet do a clean install of Mavericks after re-formatting your hard drive (explained in my previous post). I did this and Mavericks is now running very smoothly. All of the software that I previously had installed is currently installed on my MacBook now it's running fine so it's not a conflict with any software that causes the problems people are having with Mavericks. Mavericks is by far the fastest version of OS X I've ever used, it's just that a clean install will always yield the best results.

I have five Macs in the Studio, all had Mavericks installed over Mountain Lion. No problems at all. The majority of problems I have seen with other people's installs have been caused by outdated or incompatable third party software.

From what I've seen, the majority of Mavericks users would agree with you, including me. I've observed several hundred users now and a few have been able to find that one piece of software that was the root cause while a few others were never able to recover until they resorted to a clean install.


I did have to resort to a re-install a couple of weeks after installing 10.9.0 when it suddenly ground to a halt and nothing I tried would get it back to normal. An hour or so after rebooting to the Recovery partition I was good as new. My main computer has had no issues at all, yet.

Thanks for telling me about the TimeMachine clock NOT rotating! Who would have thought that Apple would remove that feature? I found that so useful! Now I don't really know when its backing up! All this superficial design change is driving me batty, not just on Mac but on IOS too! What is the real point in changing stuff we grow familiar with? To show that the're busy "improvong things"??? I always wonder if Steve would have let them do stuff like that but that's a whole other topic!

Because my MacBook (unibody mid 2010, 13-inch) is too slow, on power and in use, I follow the suggested by Linc Davis in the top of this post: in TextEdit, after I wrote the code line suggested by Linc Davis in reply to original post in Terminal application, I had the following output:

xxxxxx macbook kernel[0] <Debug>: Previous Shutdown Cause: -60

xxxxxx macbook kernel[0] <Debug>: Process Setup Assistant [225] disabling system-wide I/O Throttling


What they want to say these lines and, more importantly, how can I speed up my computer?


Important (maybe): I have installed on my MacBook MacKeeper
