  • Can I uninstall Photoshop from my Mac and reinstall it on my PC without paying again?

    Hello,
    About three months ago, I bought a package with Adobe Photoshop Elements 12 and Premeire Elements 12. I bought a DVD install that works with either Mac or Windows. I registered it under a Mac, because that's what I had at the time. However, now I have switched over to a Windows 8 PC. I would prefer not to pay again. Is there a way to transfer it without buying?

    Yes, just install it on the PC. You're allowed two activated installations so you can keep it on the mac, too, if you want. If not, just go to Help>Sign Out in the editor on the mac before you uninstall it.

  • Can I un-install Yosemite from my iMac and re-install Mountain Lion?

    Can I un-install Yosemite from my iMac and re-install Mountain Lion?

    Sorry to barge in like this but is it because you found it to have it's own way of doing stuff without your control? As i was thinking of doing the same thing because i found Mountain Lion much more user friendly.I know you came for an answer just was searching and came accross your question.
    Hope you find the answer. good luck.

  • Can not see hard drive on desktop after reinstalling Mountain Lion

    I have erased my hard drive and reinstalled Mountain Lion 10.8.4 and now I can not see the MacIntosh HD on the desk top. Downloaded the most recent updates and restarted but still do not see the hard drive on the desk top. Any ideas?

    Open Finder preferences and on the general tab check Hard disks for Show these items on the desktop.

  • Can I update only from my iMac and have data flow to iPhone and MacBook, not the other direction?

    New to iCloud and Lion.  Can I update via iCloud only from my iMac and have data flow to my  iPhone and my MacBook, not the other direction?

    No. Syncing means bringing both ends to be the same.

  • I plan to buy iMac w/Mountain Lion How do I un-install FCE and MSoft Office 2011 from old iMac and reinstall

    How do I uninstall FCE (v 4.0.1) from old iMac (OS 10.6.8 2GHz Intel Core Duo)?
    Can I re-install on new iMac I plan to buy with Mountain Lion?  I have install FCE CD.

    I couldn't remember from my earlier experience what the software was that worked, but I found FCS Remover on my Mac in Applications, so that's what I plan to try.
    That will do the job removing all the FCE related files.

    And I was surprised to learn the new iMacs don't have a DVD burner which I use all the time on this iMac and my newer Macbook Pro.  I suppose that's why the prices start at $1299?  I will look, but does the Apple store sell DVD burners?  And assuming so, do any of you have recs?
    As Keith mentions Apple sells one as an optional extra.
    There are others on the market as well.
    My experience is to do some serious homework before buying any unit to make sure it is compatible with your specific Mac. Some users have been very disappointed.
    I use an OWC (Other World Computing) bluray burner with several types of connections and it works fine.

    Lastly, it has taken me about 4 years to master FCE.  I am willing to go to FCP X if those here can advise me about 1)how tough is the learning curve if you're good at FCE and 2) is it a better program?
    Question 1.
    Totally different to FCE and you need to forget most of what you learnt there to adapt to FCP X.
    Most dramas occur learning FCP X because users try to think and use FCP X the the old way.
    It took me some adjusting to get into the new methods and thinking and terms used.
    Advice: Read the manual and unlearn FCE. Search the FCP X forum or ask a specific question, the info there is mounting.
    Question 2.
    Better is a subjective term.
    I have sold all my old legacy FCP stuff and moved on to FCP X.
    As a broad statement it makes it easier for someone who knows little about editing and the quirks of codecs to Import and Edit a Project.
    That being said the underlying complexity of the app is very powerful.
    Like all apps it's not perfect, the current version is 10.0.8 and I made the shift at 10.0.7 when it had matured to the extent I was personnaly happy to make the jump.

  • I can't boot any latest gen imacs off a mountain lion USB bootable drive

    So I have created a mountain lion USB boot drive because I work on a number of imacs, but for the latest generation it doesn't seem to work.
    I create it in the normal way, downloading the app through itunes then using http://liondiskmaker.com/ to create the usb boot drive.
    When I try to boot from it: http://i.imgur.com/IUDlv.jpg
    I get this icon on the screen: http://i.imgur.com/DNc8U.jpg
    The weird thing is that I have used this exact bootable usb stick to upgrade many, many older imacs to mountain lion. I don't want to have to redownload the entire 5gb or so every time I need to install mountain lion on a new imac. I've tried this with both the 21.5" and the 27" varieties and both have the same issue. What is causing this?
    I also need to boot from it directly rather then doing an in-OS upgrade in the odd times I'm working with an imac at a place that doesn't have a decent internet connection (6 gigs of downloading isn't available to everybody in Australia)
    Someone has mentioned that it may be due to new imacs not allowing older installation media, but I have downloaded the latest version as of 3 days ago and it does the same thing.

    It has nothing to do with Lion Disk Maker. That is only used to Create a Boot USB thumb drive, or DVD, of the Lion/Mt Lion install files. It does not add anything to either the DVD or thumb drive you create with it.
    The problem lies with the Special build Apple creates for every new Mac that comes out that has different hardware then the previously released models.
    Eventually they will come out with a new updated build, like 10.8.3, that will contain all the drivers for every Mac computer ML can be installed on, Older and the newest. Until that happens there is only one way to get a version that will boot on the newest systems. And that is to use either the Recovery HD or the Online Internet Recovery system ON one of those New Mac's. Those newer Mac's are the only one that can access the Special Build needed for the new systems.

  • Minecraft says that I need a new Java plug in but I can't find one from Support.  I thought Mountain Lion had the latest java.

    I have just installed Mountain Lion and now cannot access Minecraft.  It is telling me I need another Java plug in, but I thought that Mountain Lion includes the latest java.  Has anyone else experienced this and do they know how to get the plug in?

    Hello:
    Have you run software update after the install?
    In any event, go to utilities>java preferences.  Open that and follow the prompts, if any.

  • Replacing the HDD with SSD and reinstalling Mountain Lion

    Hello,
    I have a MacBook (Mid 2010) since August 2010. Since then, I have been using Time Machine and every time Apple releases a new OS, I download it from the Mac App Store and put it on a USB so that I can boot from it, whether to reinstall the OS or in case I faced Hard Drive problems.
    My HDD is dying slowly, so I planning to get an SSD. The version of Mountain Lion that I have on the USB is 10.8.
    The question is, do I have to download a newer version of Mountain Lion (say 10.8.3) from the Mac App Store knowing that I will be restoring from Time Machine?
    Thank you..

    Since you want to restore what's on TM to the SSD, the SSD needs to be booted from to receive the restored files and to do that, the SSD has to have an OS on it. And since you'd want to have the SSD's OS updated to the latest ML version eventually, you might as well do that first, since, to some degree, it's also a test  of the SSD's functioning. Since you already have the Combo updater, you could just run that, and since it's only a bit over 800 MB, it might even fit on the flash drive. I don't believe that migrating from a TM file made by and containing 10.8.3 data would be problematic when initiated from a 10.8.0 installation (which is I think what you're asking), but there may be some subtle software changes we don't know about that could come back and bite. So starting the migration after updating to 10.8.3 would be the safest bet. At the same time, Setup Assistant brings your existing account stuff over to just reestablish your existence on the SSD, while Migration Assistant is run after a new account has been set up on first boot, so I'd think Setup Assistant is the better way to go.
    In which case, how about this: when you run the Combo updater, you are given a choice of which drive you want to install it on. If I remember the sequence correctly (it's been a while since a fresh install), you run the installer, which transfers files to the target disk, and then reboot. The installation takes place on the target disk which then reboots again to begin the setup process. When the startup chime sounds the second time, use the option key to run Startup Manager and pick your flash drive to boot from again. If you already have the Combo updater on the flash drive, run it from there and pick the SSD as the target. When it's finished, if it doesn't start from the SSD, choose that as the Startup Disk (check to see that it says 10.8.3 in Preferences) and when it boots, start the Setup Assistant process using TM.
    Or is the flash drive only an installer, meaning it doesn't actually have ML installed on it so you can't use it like an actual boot disk from which you can do normal boot disk things?
