Fullscreen apps have some issues. I can't seem to access the menu bar in fullscreen apps anymore. Also, it's hard to get them out of fullscreen view once they're in fullscreen. Sometimes the fullscreen button shows, sometimes it doesn't. That's the only major bug I've found.
 
I've upgraded to Mavericks as my main OS for my 2011 MBA and 2012 iMac without making a time machine backup of Mountain Lion!

The only minor quirk I see is that when I close Messages with CMD + W or the little "x" it loses the little glowing thin rectangle on the bottom, indicating that I've totally quit the program. It is actually running though, even though the little glowing thin line isn't there.

you may regret that, i've reverted because as people say it is a developer preview.

I can't wait for this to be finished, enjoyed playing with it on my retina macbook 15 but i restored my time machine backup of 10.8 for stability / app compatibility for now.

Definitely miss how smooth safari is but the rendering is far more stable in Mountain Lion for now. Can't wait for mavericks to be live.
 
In the past I always jumped straight to beta versions. Not anymore, even final version will have bugs at the beginning and imcompatible apps. I sugges to wait one month after release to migrate, or, test it in a different partition fron beata version, and when all is setup and ready, trnsfer it.

Indeed.

I have always been a "very early" adopter, but over time have grown to be annoyed with little (and big) bugs present.

Tbh. after years of doing certain things, I decided to read (and follow) the release notes... It makes life a little bit easier... At least for me...

(Ah, love the first world problems)
 
Finder crashes, gpu drivers still buggy (core animations *very low*), some apps not working, translations in other languages not finished... And other issues mentioned in this thread that I didn't experience...

Everybody wanting to upgrade on a production or daily machine should just restrain.

I've put it on another partition for development purpose, but I would never dare use it for other works (or games) right now.

All in all, the only *real* features I want from Maverick is the true dual screen fullscreen capabilities, and airdrop with iOs 7.

If you only have one computer/partition. Create a bootable disk of the Mavericks installer (instructions in this subforum) then boot into the installer (hold down option when starting the computer and pick the installer) wipe the partition you installed mavericks into. Then restart your computer. This time boot into a Mountain Lion installer (you can also create a bootable disk for this…Google it) and install it into the partition you just wiped.

So if I already installed 10.9 and I made a time machine back up of 10.8 I have 2 options?
1- create a ML bootable disk and boot into it and install over 10.9?
2- Just enter time machine and restore from back up?

Or do I need to create the bootable mavericks disk, boot into it, wipe the entire partition using Disk Utility? using the Erase tab? or...?
and then after the partition is wiped (however that's supposed to happen) then I remove that disk and insert the bootable 10.8 disk and boot into it and install that over mavericks? or did I already delete 10.9 when wiping the partition and now I'm just loading new OS?
then I use time machine with migration assistant?

Ugh, I'm an idiot. I am really only needing to be working on ios7, I shouldnt even get involved in this OSX stuff, but I HAD to try the airdrop and airplay to separate monitors. This is my first DP/beta for OSX. I have no experience, at all.:(

Troll away guys. Flame on. I deserve it.
 
Laptop in my signature. Installed Mavericks DP1 pretty much as soon as I had the chance. The laptop is boot camp enabled with Windows 8 and I installed the DP1 straight over the top of 10.8.4 without any wipe.

I generally don't look back and install any updates I can get on my laptop but I'm probably a unique case. This laptop has literally all important files stored in dropbox and synced to my desktop, and all media stored on my server (which works great with SMB2 mind you!) so I wouldn't have lost anything if I did have to wipe it and start again.

TL;DR It's stable, I took the plunge and went with it, usually don't follow my lead.
 
Skype crashing, Little Snitch not working (maybe they have nightly, didn't check), Flash/Shockwave crashing making browsers unstable. That's about it 4 me...

You have to use a Mavericks installer its the only installer that can wipe a Mavericks installation as far as i'm aware. Because ML is an older installer.

However try the Time Machine restore option first. If that doesnt work then do the Mavericks installer option and then just use Time Machine to restore your data after wiping the partition (Disk Utility Erase tab) and loading ML onto it.

or did I already delete 10.9 when wiping the partition and now I'm just loading new OS?

You've already wiped and are just loading ML onto an empty partition.

After several days of usage: i had some system crashes here and there, especially when browsing in Safari and using Photoshop. But for a beta, really really stable so far!
 
I've been using Mavericks for around 24 hours now on my 13" 2011 MacBook Pro. I mostly don't even notice the upgrade, sure Calendar looks different and I can now have tabs in Finder but apart from that it's like it was before. So yes it's stable but it's also not very exciting.
If you're considering using Mavericks on your primary computer I'd say go ahead as long as you're not professionally dependent on everything functioning perfectly.

Wow. A whole 24 hours. :eek: Release the GM already!

Some of you guys continue to crack me up. :D
 
Main problem is not just the os stability, but the third party apps, which are currently developing updates to work perfectly in the new system...

I have it in a partition to have a polished system. When all is perfect, I will transfer this secondary system to the main partition in the ssd... That is the awesome thing with osx and partitions and time machine.

I even leave the current system on the secondary partition for a while.
 
I'll wait this one out or install it on an external drive. The sheer amount of stuff I have to reinstall and configure if I encounter serious bugs makes me shudder. :(
 
Just installed it. It's fast. Like, really fast and snappy and responsive. There are still a few glitches regarding displaying other languages, but overall it feels very stable. System wide animations are a bliss, Launchpad animations are gorgeous, without those horrific resource hogging linen textures.
Safari feels great, scrolling in Mail is unbelievable as well.

This feels like rock solid OS. The Snow Leopard of its age and I'm running it on a late 2008 uMB.

How do you install? Im currently downloading the file right now..just open it in the app store?
 
only issue I'm encountering is that I can't sync my google account with OS X if it has a non-google domain. I've noticed that I can't sync with google in Contacts (used to be in On My Mac Local).
 
Yeah, some people getting a little over-sensitive about how this Developers Preview is being referred to.

We all know what it is. Sorry we're not calling it exactly what you want us to call to it.

You completely misinterpreted the point of my post. Nice job
 
Installed from ML since day 1 and not even a crash. Disconnect your TimeMachine for precaution but, im using it and its very very stable.

Some 2seconds freezes on safari but it balance with the high speed too.

Student level, just safari, itunes, parallels, spotify, Skype, mail.... etc

Same here. Installed day 1 and everything is all hunky dory...
 
Is anyone seeing the dock freeze on shutdown? It half disappears and then freezes until it shuts off completely
