Been using OSX since 10.3 - Mavericks is the buggiest OSX ever. I have a late 2013 MBPc and it runs noticeably slower. Tried a fresh install - same thing. Tried mountain lion again and it ran smooth and peppy as it should. it makes my new computer run as sluggish as the 6 year old MBP it replaced. SHAMEFUL.

I hate how Apple makes you upgrade to Mavericks in order to get the iLife and iWork updates. LAME. I'd stay with Mountain lion if I could - for now I have to put up with the sluggishness to get the features and updated software. I wonder if it has to do with the compressed memory and running software that isn't optimized for it.

Isn't Mavericks a beach in California? Maybe that's why the OS is full of beach balls?!?

Mavericks is optimized for SSDs in the first place, and runs horribly on HDDs. Probably because Federighi's engineers were developing Mavericks on SSD-only Macs.

But honestly, HDDs are so yesterday. An SSD is worth it even if it's costly.
 
Mavericks has also made ALL my Macs useless.

I believe you, but....

It seems many members of Apple forums (not just this one) simply refuse to accept reports such as "everything was fine until I installed Mavericks", even though we see such reports over and over and over again, on an almost daily basis. On the Apple Support Forum it's almost hourly.

I've spent a good bit of time on religion forums over the years, and it's remarkable how many of these threads read just like that.

Some fellow Mac user sincerely reporting a Mavericks related problem is likely to get a series of replies like this....

It couldn't possibly be the infallible Holy Mother Ship that is the problem. It must be the user's fault, or some other developer's fault, or bad luck, or maybe the Devil did it! The Holy Mother Ship is working fine for me, and that's proof that you are wrong. Watch out that you don't become an blaspheming apostate heretic!

Really guys, it just gets to be too much after awhile.

Couldn't we just believe the poster, who knows far more about their situation than we do, until such time as we have specific evidence which indicates their theory might be incorrect?

In another thread on this forum an Apple programmer who is working on Mavericks honestly disclaimed that Mavericks was full of known bugs, but Apple released it as ready anyway. He was apologizing, because he knew this wasn't the right thing to do.

Good for him. I feel bad for all those sincere truly professional people working at Apple who are put in such an embarrassing position by others up the chain in the business and marketing departments.

And THAT is why so many people are coming to Mac forums reporting problems with Mavericks.

Mavericks was released full of known bugs.

It's NOT the user's fault.

It's NOT bad luck.

The Devil didn't do it.

It's Apple's fault, as reported by someone within Apple in a position to know.

I'm not suggesting we should all therefore hate Apple.

I am suggesting that users reporting Mavericks problems deserve the benefit of the doubt. Their problems are real.

Explain to me why an OS would run better on a SSD compared to a HDD other than the obvious speed improvements due to a SSD? Do you think that Apple wouldn't bother to test Mavericks on older machines with HDDs? That would be extremely sloppy of them.

The hardest thing about laptops IMO is the lack of hard drive space. I run large sample libraries on my computer and need as much space as I can get. Often I work on the go and it's not practical to carry or supply power to an external hard disk. So do you think I'm going to go from a 1TB HDD to a 256 or a 512 GB SDD? Besides, my computer isn't even 6 months old - I'm not going to pay to upgrade to HDD drive just to upgrade to Mavericks and lose the hard disk space.

If you think HDDs are so yesterday, how about compressed memory? I haven't compressed memory since DOS. Plus, going from 1TB drives back to 25x or 5xx GB drives seems like a step backwards as well.

The return of 'compressed memory' makes sense, because with modern multicore cpu's, the compression overhead is pretty negligible, and the performance is significantly better than swapping out to the drive (and because of this, I'd think mavericks would actually perform better on older hdd's, especially in memory intensive scenarios).

I have used very release of OS X from 10.0 onward, and I can say that Mavericks is not the worst OS X version ever released. I'm also not going to sit here and say its the greatest thing since sliced bread, it isn't. Mavericks still needs work, but I haven't noticed very many problems on my rMBP. Notice, "very many", as in yes I have had problems. Video distortion and 1 Kernel Panic have ensued in the months since getting this machine, but all the issues have been fixed with a reboot, SMC or PRAM reset.

Also, you don't have a "late-2013" cMBP, as there is no such thing. You may have purchased it in late 2013, but it is actually a mid-2012 model. My iPhone is a late-2013 model even though I purchased it in early-2014. My iPad is still a late-2012 model even though I bought it in mid-2013.

I have also upgraded 4 machines to Mavericks. One was a move from an 2006 MacBook (SL) to a 2010 MBP (ML) which was then upgraded to Mavericks with no problems. Another was a Lion machine that went to ML shortly after release and now Mavericks, all run as upgrades. Hasn't missed a beat to this day. Another one was a new MBA which came with ML preloaded. That machine was restored from a backup spanning 3 machines and 4 OS releases. Smooth sailing. The 4th was clean install.

I'd say kernel panics are a pretty big problem. I'd hate that to happen while teaching a class or giving a demo. Clearly you're more forgiving than me when it comes to computers.

Yes, I meant with the late 2013 that I had purchased it in late 2013 meaning it was a fairly new computer. I should have been more clear but I think your correction was done more for derogatory purposes anyway.
 
PLEASE HELP! I cant log into any aacounts after installing maverick

I recently installed the new maverick osx and after installing i went to log into my account and i couldn't get through. I tried even using my admin password and that did not work either. I then tried to reset the admin password in terminal and that didn't work. I also did a clean install and that didn't work either. I called apple care and they had no clue:confused: oh and i forgot i even made a new account and even just after creating a new account and password it STILL did not work!!!! wtf?! Any help would be greatly appreciated !!!

The poster stated they had ONE kernel panic. That would only be an issue if it occurred again.

How does this not make sense, sorry I'm not super computer literate. I couldn't find out how to post my own thread. But I'm having issues logging onto my user accounts after i installed the new mavericks. I have no idea how to get back into my computer.
 
Can you explain to the steps you went through to do a clean install?


I called apple care and they walked me through it. I Held the command R buttons and then went to the utilities menu. Reinstalled the mavericks program after checking that my hard drive was good in the same menu options, i can't recall exactly what it was called.

When you were reinstalling, if you didn't actually format the drive manually using Disk Utility in the utilities menu, you did not do a clean install.

Do you have any idea or suggestions on how I can get back into my accounts without deleting them or anything on them?

It was one Kernel Panic and it hasn't happened since. It was under 10.9.2 too. And no, I'm not forgiving at all when it comes to computers. If it was happening multiple times (like what happened after the "Geniuses" installed a new LoBo in my 2012 Retina), I would be calling Apple. I pay $2200+ for a machine, it better ******** work! But when it happens once in 5 months of ownership, I see no issue as I probably would have had a handful of BSOD with Windows by now.

Also, no I was not being derogatory, I was explaining what the "late-xxxx" meant. It was in no way meant to be derogatory. If you took it this way, allow me to apologize. I didn't mean for it to come out like that.
 
yjchua95, mavericks may be optimised for SSD but I have a few HDD's connected to my MBP retina.

What I think the problem is- I do a spotlight search it spends a lot of time sorting the files not just from the MBP retina but the external HDDS.

It seems to be #$#$%%$%!% slow because of that.

I love that it sorts the files but the speed of it is soul draining.

SSD's are expensive, I have 4TB's of externals for my work that is mainly photography, video, graphics.

I cannot afford 4TB's of SSD.

I am also having a horrid time with Mavericks, on a 2011 MacBook Pro. In my case, it is worst when an external USB drive is connected.

There is quite a lot of dicussion on the 'net about Mavericks-related performance issues.

I recently disabled memory compression, and updated to 10.9.3. One or both of those changes has made it much more bearable. Certainly not as quick as Snow Leopard, but at least it no longer makes me want to stick sharp objects into my eyes (well, really, it just no longer feels like quite such <b>hard</b> work to get things done, like it does when it takes 15 seconds to open Sys' Pref's).

So since memory compression is just a setting, I'd suggest that those of you still having performance issues consider disabling compression. You can always switch it back.

I'd have to bet on something being wrong with your machine, the HDD or something.
One of my dear friends also ALWAYS has some kind of problem with her MacBook....ALWAYS.
My wife and I have 7 different model Macs at home, my friends husband has a MacBook, her kids have 2. Every Mac is running Mavericks perfectly except for hers.
1 out of 11 with problems 2 families not counting the other 20 I have at the office that are used 10hrs a day 4 days/week and let me tell you, my girls are used to the systems running flawlessly with no hiccups and they will blow my phone up if anything slows them down and honestly the problems they tell me have nothing to do with the OS it is always our practice software.

Also, she won't take the machine to Apple to have them look at it like I've advised her too for 3 years, now AppleCare has come and gone and she still has problems but hasn't done anything to try and get it fixed other than call me and there are 6 AppleStores within 20-30 minutes away.
 
Some troubleshooting is required here.

Step 1: full system backup to an external disk. Use super duper or carbon copy cloner.
Step 2: make a mavericks boot disk or USB, boot, use disk until and erase the drive. Now install mavericks.
Step 3: run the clean install without restoring any user applications. Setup the basics, like email etc and see if the rogue process appears.

If all is well then one by one install your applications and see if the performance issue returns.

If all is not well then it should be easier to see what is at issue on a clean install. Get back in touch with Apple and let them check it out.
 
It's really weird to hear about all these problems with Mavericks. My rMBP runs mostly flawlessly with Mavericks. Much better actually than with Mountain Lion.

I've had only one problem which didn't even affect the performance being only visual flaw.

All I can say is that I've been VERY happy with Mavericks in overall. Hopefully others will get their problems solved out.
 
I Fixed My Problem

I finally fixed my Mavericks problem. I too had issues with beach balls and long login times etc.

They key, like everyone says, is to completely reformat the drive using disk utility and install from scratch. This included removing my old bootcamp partition (Windows installation) and later recreating it with Mavericks (rather than leaving the old one created by Mountain Lion).

Since I had no Mavericks boot disk I had to use my Mountain Lion boot disk to wipe the drive, install ML, then upgrade. That would be clean enough right?

Wrong. I still had problems.

Several weeks later a company updated their software Diskmaker X to support Mavericks and allowed me to create a proper install disk.

Everything now is running quick and speedy as it did in ML.
 
My first guess as to the cause would be something like a printer driver or something else that constantly runs on the background (like a UI modifying program such as iStat Menus) crashing and thus hogging up the CPU. After that it could also be Finder doing indexing, because after every major OS update it does a complete re-indexing and over time it does partial re-indexes as the files on your HDD/SSD change.

I've encountered plenty of people complaining about the same kind of issues as the tread starter and it's usually Finder doing indexing. I've personally a few times come to wonder what's hogging up the CPU and found out that it's Finder doing some indexing. However the reason why I still think something crashing is a more likely culprit is that when Finder does re-indexing, it's doesn't take that long because full disc re-indexing are kept to full OS re-installs and version updates. I've personally seen this be the culprit more than once.

Also, as people are posting Kernel Panic reports my suspicion is falling on bad drivers as Kernel Panics are generally caused by drivers crashing as Apple has in their infinite wisdom made drivers run in Kernel Space (Microsoft moved them out of there with Windows 7) because if you have a crash there, you get a Kernel Panic. This was the main reason why Windows XP and Vista suffered from BSOD's.

What about the ArsTechnica article on making a USB boot & install drive without the DiskMaker software?

http://arstechnica.com/apple/2013/10/how-to-make-your-own-bootable-os-x-10-9-mavericks-usb-install-drive/

The following command worker perfectly after I downloaded Mavericks.
Code:
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction

you just have to tweak it for the volume name of your particular USB drive.

I'm attaching a screen shot of what mine looked like.
