I just upgraded from Mountain Lion to Maverick (10.9.3) and Adobe CC is listed as incompatible with this OS.  What do I need to do to make it work again?  Just a patch/update or do I need to uninstall and install?

Where are you seeing that information? Got a link?
According to the Adobe website: Mac OS X Mavericks (10.9) compatibility FAQs | CC, CS6, Acrobat
Plenty of people, including me, are currently running CC on Mavericks.

  • I have upgraded from Mountain Lion to Mavericks, since then my Adobe Flash Player don't want to work?

    Hi, can anybody help me please, i have upgraded from Mountain Lion to Mavericks, since then my Adobe flash player don't want to work.
    I clicked on update and downloaded the update from Adobe and installed it.
    Every time i get an error saying - "that this wasn't downloaded from App Store".
    i can not find it in App Store.
    What must i do?

    Try this: in your Utilities folder launch Adobe Flash Player Install Manager and run it to completely uninstall Flash. Then go to http://get.adobe.com/flashplayer/ and download Flash
    Once downloaded, double-click to open it and run the installer. If you get a message saying the file can't be opened, or similar, Control+click or right click and select 'open' and should then be able to proceed to install it.

  • Error when upgrading from Mountain Lion to Mavericks

    Has this happened to anyone and what did you do to resolve it?  Error: "install failed - The OS X upgrade couldn't be started because the disk Macintosh HD is damaged and can't be repaired.  After your computer restarts, back up your data, erase your disk, and try installing again."

    OK,
    I did the following (I did not purchase DiskWarrior or any other 3rd Party software)
    Backed up to an Time Machine Drive
    Reset the EPROM (zapped it or whatever they kids these days are calling it)
    Booted off a Mavericks USB stick.
    Ran Repair Disk & Repair Permissions
    Installed Mavericks
    Worked fine, took a while but up and running.
    Not sure what the HD damage error was but it's working away on my old work horse (17" Late 2007 MacBook Pro).

  • Upgrading from Mountain lion

    I am upgrading from Mountain Lion to Mavericks. I tried to install Mavericks from the AppStore, everything went OK (download, etc), until the system had to reboot and it was when everything failed. The system couldn't start, it stalled when the apple logo appeared, but the mouse was resposive (really weird). I tried several things cleaning the PRAM, etc, and there was no booting, or alternative to start the system. After trying all the different combinations to boot and see no change, I realised that the left option key somehow was unresposive at startup, and that was one of the identified problems. However, I manage to use the right option key and I was be able to boot from an external hardrive using a recovery partition from a clone of my system. I restored the system with my back-up from Time Machine of 10.8.5. I have a mid 2010 MacBook Pro, where I have a SSD drive. My drive is OK and It was checked prior to installation of the system etc. Any Ideas on how to able to install 10.9, or an expected release date of a new installer? It seems this has been happening to a lot of people.

  • Mavericks upgrade from Mountain Lion deletes all user accounts

    This is a lesson for upgrading too early (and too eagerly).
    Today I tried the Mavericks upgrade from Mountain Lion on my 2007 Macbook Pro, after going through all the pre-installation/pre-upgrade checklists.
    I don't think I have gone from a very high to a down low in such a short space of time.  I really wanted to move on from Mountain Lion and when the installer finished the upgrade to Mavericks and re-started my MBP, I was super excited.  When the restart completed and I was presented with the login prompt, I tried entering my user name and password.  First time, it shaked on the password... OK, you'd think that is a typo.  Re-entering the password... same thing.
    You can imagine what ensued.  After entering my password v-e-r-y slowly many times, I started realising that something went very VERY wrong.
    Just for information, I used two different user accounts on my MBP under Mountain Lion.  The one account had administrative priviledges and was only used for installing applications and a few other administrative tasks.  Then I have a second personal account, which does not have administrative priviledges and is the account I use daily for Mail, Safari, iTunes, programming etc.
    None of those accounts worked under Mountain Lion.  Basically, there is no way in.
    I then proceeded to boot with the startup option Cmd + S (command-line access).  Once that was completed, I was in as root and checked the /etc/passwd.  None of the user accounts were there.  I was only able to find two user accounts: root and nobody; and a long list of user account that started with an underscore (I think these are some sort of esoteric user accounts).  So, it appears that the Mavericks upgrade did not accurately bring over the user account information from my Mountail Lion installation.
    Then, I went into the /Users directory and there I could see the home directories for all the users as they were defined under Mountain Lion.  The contents were intact too.
    It seems to me that the Mavericks upgrade from my Mountain Lion forgot to bring over the user accounts but it did preserve the contents of all the users' home directories.
    Unless anyone can spot some sort of user error here (please let me know), I am heading back to Mountain Lion pretty swiftly.  Otherwise, I suspect there is a bug in the Mavericks installer.
    Any assistance is appreciated.

    The reason this occurred is a mystery and has not been commonly reported. Consider the following. It may or may not help. You should probably print these instructions before proceeding.
    Boot Single User mode again and do the following:
    (You can skip the first step. It will check your boot volume for errors and correct what it can. If there were errors the installer should not have proceeded, but the possibility exists that directory corruption may have occurred during installation. That seems unlikely to me but could explain what went wrong.)
    In Single User Mode:
    At the :/ root# prompt, type fsck -fy and press Return or Enter. It will take a few moments to complete. If you are concerned that nothing is happening just press the Return key until you see the :/ root# prompt again.
    Once the disk check is complete and the prompt returns, type mount -uw / and press Return / Enter.
    Type launchctl load /System/Library/LaunchDaemons/com.apple.opendirectoryd.plist and press Enter. If you get an error message you may ignore it.
    Type ls /Users and press Enter. All of the usernames on the computer will be listed, which is helpful if you don’t know or remember what these are.
    Type dscl . passwd /Users/username password while replacing username with one of the users displayed in the previous step and replacing password with the new password of your choice. Press Enter. You will likely get an error message about a file or directory not being found. You may ignore this.
    Type reboot and press Enter.

  • IMac CPU3.06 GHz Intel Core 2 Duo, 8GB, Extremely slow and repeatedly "out of Memory" since migration from Mountain Lion to Mavericks

    Dear Apple Support Community.
    As mentioned by a number of users reporting the same problem, my 2009 iMac CPU3.06 GHz Intel Core 2 Duo, 8GB RAM, has become extremely slow and repeatedly "out of Memory" since it was migrated from Mountain Lion to Mavericks (OS 10.9 then OS 10.9.1).
    I have already run CleanMyMac, deleted 5GB of useless stuffs, which did not translate into any improvement. Following the advices collected in other Apple Support Community threads, I have applied EtreCheck the outcome of which is provided below.
    For information, I have also upgraded my 2011 MacBook CPU2.3 GHz Core i7, 8GB which became only a bit slower than before, sometimes freezing which it almost never did before. However, I am used to the fact that Mac get usually slower and more prompt fo freeze after upgrading to a more recent OS.
    Both my 2009 iMac and my 2011 MacBook have F-Secure installed. So the problem with the 2009 IMac is unlikly to be due to the presence of F-Secure. Interestingly, the few abnormalities found by Etrecheck were exacly identical before I ran CleanMyMac. There are two more findings (mentioned below) since I ran CleanMyMac on the 2009 iMac, which again didn't improve the problem.
    So please find below the details of the EtreCheck experience and some additional measurements made with iStat while running EtreCheck:

    Practically:
    The iMac can work slowly with only one software e.g. either Mail or Safari or Firefox, but still the below "out of Memory" message occurs about every 3 minutes.
    Aperture has becomre to slow to be useable
    If trying to write a mail (with Mail) while Safari or Firefox is open, then the "out of Memory" message occurs about every 20 seconds so I need to check on "Resume" several times per minute.
    Conclusions
    From the above, unless anyone in the Apple Support Community proves to be able to identify a specific problem leading to a way to find a cure, I tend to conclude that Mavericks is not suitable for computers operating with a Core 2 Duo CPU even with a 8GB of RAM.
    Unless I missed something, I did not see any warning from Apple Computer Inc. informing their customers they should refrain from upgrading Core 2 Duo Computers.
    The only solution I see so far is to downgrade from Mavericks to Mountain Lion. And the Apple Support Community would confirm that it is the only solution, I would appreciate to get your guidance on how to proceed.
    Intended action plan
    Migrate the above 2009 iMac to a 2014 Mac Mini Server operating on Mavericks to ensure that no data may be lost while downgrading to Montain Lion.
    Provided the above downgrading operation is successful, assign this 2009 iMac to partial retirement e.g. Mail, Skype, iTunes  and DVD player.
    In advance, I would like to thank the Apple Community for helping me either i) finding a cure to the problem, ii) or confirming that Mavericks cannot operate properly on Core 2 Duo computers, iii) and in such a case, guiding me on how to downgrade to Mountain Lion.
    Yours sincerely

    ... what anti-virus would you recommend using?
    Use what is already included with OS X. It already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
    A much better question is "how should I protect my Mac":
    Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
    Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
    Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
    Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
    Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
    Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
    Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
    Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
    Don’t install Java unless you are certain that you need it:
    Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
    Disable Java in Safari > Preferences > Security.
    Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
    Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
    Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
    Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
    If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
    Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
    The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
    OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
    Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
    If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
    Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
    Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
    Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.
