I have Yosmite on an external hard drive.

And used time machine to restore the personalisations.

crashes a lot.. but better than vmware. Vmware fusion 6 won't start at all on yosemite

There is a Compressed Memory column in Developer Preview 1, so yeah.

Yes of course.

Thanks a lot bro.
Guess i will hold.

-pWs-

this was an issue....at least for me...., i would have to clear the data manually from each one of my device......

Installed Yosemite DP3 on my MBP on Tuesday. Stable enough for daily use except for a few minor issues :

Safari Tabs is a bit bugg, not showing at times..

Activity Monitor crash on launch

Dual screen causes the new transparency effect on windows to flicker (Just on Safari)

Other than that.. 10.10 is more refined than 10.9 in some ways. Loving it!

how about the memory consumption?
will the device with only 4gb ram able to run smooth?

I think 4GB will run it just fine if you are not a heavy user.

if run photoshop, etc sure lag?

Vmware Fusion 6.0.4 is now working on Yosemite. Haven't been running on it long enough to encounter any crash.

Depends on how big the file size are. Large photoshop files requires at least 8GB to load properly. 4GB is doable but will encounter some slow downs. 4GB is the bare minimum for general Photoshop usage.

Not really. It depends on how heavy your Photoshop work will be.

Apple releases OS X Yosemite Public Beta

http://9to5mac.com/2014/07/24/apple-releas...te-public-beta/

I rather wait till their final release this October hehe ios8 will release on september btw

Received my invitation to the Public Beta this morning. The release will be the same as DP4 but with slower updates compared to the Developer's Preview build.

So, I've received the email too.

Next week is break, so that means more time to mess around with the beta.

my keep error when download the beta

I have been using it now, already encounter a few issue, those who use their MAC for their everyday work, don't install it, stutter lag sometimes.

Downloaded Yosemite public beta, and install on my 2nd partitioned HD on my 27" iMac model 2009. First impression after 24 hour use:
1. visual appearance much more pleasing than Maverick, which I like.
2. no issue during installation.
3. feel much more snappier than Maverick.
4. migration assistant works well too, to transfer the apps.
I should say so far so good.
Looking forward to official Yosemite release this fall.
Word of caution though! do not install in you main working partition drive for this public beta osx. Better be safe than sorry.
