This is no new OS, it is a developer preview FOR DEVELOPERS!I am hearing too many programs not working under the new operating system.
Are you a developer? If not, do not use this developer preview!You feel comfortable moving forward with this as your main operating system?
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.
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.
Why would you install 10.9 beta 1 as your main OS if you were not willing to stick with it through the revisions?
----------
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.
or did I already delete 10.9 when wiping the partition and now I'm just loading new OS?
I've been using Mavericks for around 24 hours now on my 13" 2011 MacBook Pro.... 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.
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.
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.
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
