    It was zippy after the upgrade. It's zippier after the clean install, but drastically improved, that's a matter of opinion.

    Wondering..

    I was actually wondering the same... When I purchased my rMBP, I asked the salesperson about whether or not I should do a clean install of Mountain Lion.
    She told me I didn't have to because OS X is different to Windows and usually with Windows its ideal to do a clean install but with Macs you don't need to.

    Since this is my first Mac I just said Okay and left it at that. I'm still not sure of what to do though... I'd probably do a clean install just to get it out of my head and stop thinking about it later on lol :rolleyes:

    I think I am too lazy to do a clean install, so far so good on the upgrade. It is running really well for me.

    Since you are unlikely to be running any legacy software and probably don't have many 3rd party plugins etc installed yet, you should be fine with the upgrade. I would recommend a clean install for people like me who have old bits of ppc or other incompatible software lurking in hidden directories.

    If u restore via Time Machine does that incompatible software lurking in hidden directories gets restored as well? because after doing a fresh install I would need to restore my stuff....I did a upgrade from Lion to ML and I'm having issues with iCloud sync not working....there is a iCloud process called UBD that is a huge CPU hog and each time I launch iWorks, the new Notes or Game Center application my CPU goes skyrocketing and so do the fans. I have made a thread and so far no one else has experienced it....

    Not only is the process called ubd a resource hog it is also creating com.apple.ubiquity.peer-uuid key(s) and certificate(s)...made up to 23000 at one point when I let it run continuously for an hour.....my KeyChain Access window was FULL

    I upgraded from Lion to Mountain Lion GM when it became available. Today, I decided to do a clean install and I noticed no increase in speed. Everything works just as before. I think piece of mind after doing a clean install is a powerful placebo for some people.

    What Macbook do you have? Also is your iCloud sync working properly? Are you able to see your "Notes" and iWorks docs that you create on the spot across your devices (after installing ML) as well as sign into Game Center?

    Also I dont understand how iWorks from mac side is suppose to sync over:S

    When I go to start a new document in iWorks on the top left of that window it says iCloud and right next to it says MAC.

    If I select iCloud all it does is hides the side bar...nothing else changes...I still see the same Documents folder that I would be normally in...Also I saved a couple of test documents while under "iCloud" selected in that window but nothing appeared on iClould.com and on my iPhone.

    I have an early 2011 Macbook Pro.

    My notes sync perfectly. Check to make sure the Notes box is checked under your iCloud settings in System Preferences.

    In regards to iWork, I just created a test document and it worked just fine. Here is what I did:
    1. Open Pages
    2. Select New Document
    3. Type something on the document and then save. The default saving location is iCloud.
    4. Close Pages on mac and open Pages on iPhone.

    Hope that helps.

    Thanks, I did just that earlier but one more question: When you select "iCloud" isnt it still saving your document in the same folder as if it was stored under the "Mac"?

    No. If you choose to save your document to iCloud it will be stored on Apple's servers and pushed to each one of your devices. However, if you want a local copy you will have to make that selection when saving your document.

    The older the Mac, the more benefit you'll get, IMO. My early 2009 iMac was a little sluggish after the upgrade and markedly improved after a clean install. My 2011 MBA, though, was pretty much the same.

    YMMV, as always.

    I also have a rMBP, and while I considered doing a clean install I think an upgrade is the way to go. The computer is just over a month old, and the point of the clean install is really to clean out all the junk that has been building up in your computer, which in a month old computer shouldn't be all that much. From what I understand the installer does a good job of replacing what needs to be replaced and not keeping junk from the old OS. If my computer was a year old or so I would probably go clean install just to clean it up a bit. But after a month? I don't think I would see any performance upgrades, it runs just as smoothly as it did the day I got it.

    I believe it depends what you import, but yes, it does. There are a couple of things I'd recommend before you try to reinstall. So you know, I suspect that ML has bugs that cause problems when connecting with servers. One problem has to do with attempting to write to the server when it shouldn't (I've seen a few problems now with IMAP servers in particular).

    First of all, make sure that your computer has finished syncing with the server and that spotlight isn't running (the spotlight process is mds and mdworker - it sounds like they aren't giving you problems). Spotlight no longer indicates when it is indexing, that's why I mention it.

    Second: do you have Mail running? If you use Mail, do you have any accounts set to store data locally?

    Third: Now this is more to do with fixes. As a test, turn off your firewall, restart your computer, and try connecting to the same services. Does the issue continue?
    b) Restart in recovery and reset ACLs (Terminal ->resetpassword). Don't touch the save button, just click on your HD, select your username, and start the repair process. When done, I've found it's better (don't know why) to just quit the password reset application and Terminal and then restart the computer.

    b) Delete the ubiquity folder in ~/Library/Application Support, restart, try again.

    Fourth: I've just looked through the thread and noticed that your problem is related to local storage of a document. If 3 doesn't work, basically the only fix I've been able to work out is to start from scratch. What you need to do is completely restart your connections with iCloud. By completely restart, I mean remove your account from Mail, Contacts, & Calendars, and iCloud if any persist, and all remaining files associated with it; all preferences, calendars, everything.

    To do this you'll need to go through a number of folders in /Library and ~/Library. You can backup these files and folders if you like, but they need to be removed from the 'view' of the system. So, all preference files, Application support files and folders, local folders, Cache folders, etc. These files can all be remade next time you start the apps.

    I would also recommend going in to Keychain and making sure that it does not need to be repaired. (Keychain ->Keychain First Aid). If it needs repair, fix it. There probably isn't any harm in removing those ubiquity certificates either.

    Restart computer and set up your iCloud account again.

    I hope you don't need to get to step 4. If so, I'll try to be more specific about the files etc. to remove. Simply turning off iCloud isn't enough. Basically, you want to set it up as if for the first time.
