    ?  Why does my Photoshop PS2 open on my Mac Book Pro OS 10.6.8 Intel Core 2 Processor but not on my just purchased Mac Book Pro OS 10.7.3? On my new machine I get a message saying "You can't open Photoshop CS2 because Power PC applications are no longer supported". I don't have a Power PC on either machine and this App does run on the older machine with an Intel processor. benrusy

    This is not new.  The fact that Mac OS no longer supports PowerPC applications starting with OS X Lion has been known for over a year now.  You'll need to upgrade to the latest version of Photoshop

    Hi  can any body please tell me how to open the .exe files in mac and why it is not supported with unarchiever app , also i am not able to run and dvd's in my mac its not accepting any cd's or dvd'd why? do i need to do some pre defined  settings to run the cd's and dvd's ?

    A .exe file is a Windows executable. OS X does not run Windows programs. If you need to use .exe files then you will need to install Windows on your Mac:
    Windows on Intel Macs
    There are presently several alternatives for running Windows on Intel Macs.
    Install the Apple Boot Camp software.  Purchase Windows XP w/Service Pak2, Vista, or Windows 7.  Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows.  Boot Camp enables you to boot the computer into OS X or Windows.
    Parallels Desktop for Mac and Windows XP, Vista Business, Vista Ultimate, or Windows 7.  Parallels is software virtualization that enables running Windows concurrently with OS X.
    VM Fusionand Windows XP, Vista Business, Vista Ultimate, or Windows 7.  VM Fusion is software virtualization that enables running Windows concurrently with OS X.
    CrossOver which enables running many Windows applications without having to install Windows.  The Windows applications can run concurrently with OS X.
    VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris.  It is not as fully developed for the Mac as Parallels and VM Fusion.
    Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc.  There are performance differences between dual-boot systems and virtualization.  The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion. Boot Camp is only available with Leopard or Snow Leopard. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
    You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.

  • Why can't I get Back To My Mac to work in both directions between my 2011 Mac Book Air and my 2012 Mac Mini?

    Why can't I get Back To My Mac to work in both directions between my 2011 Mac Book Air and my 2012 Mac Mini? The network uses a Time Capsule. Everything works when connecting from the Mini to the Air, but the reverse is not the case, none of the Mini's drives are visible, and the screen sharing option is not available. I've tried the measures already suggested in online articles, everything seems to be configured correctly using my iCloud account. I'm at a loss, any suggestions would be appreciated.

    I've now managed to get the service running in both directions, but not in the way I had anticipated. I had to create a second account on the Mac Book Air, this also has administrator privilages, everything works fine when connecting from this acccount. However, this is not the way I would expect to work, none of my documents, applications and settings would be available, unless I laboriously duplicated them to the new account.
    Also, I've yet to get the service running from outside my home network.

  • Why no Acrobat Pro 9 trial versions for Mac

    I received my upgrade box for CS5 and the instructions said to delete (uninstall) Acrobat Pro 9 and then re-install it from the included disk. No big deal, I installed CS5 then uninstalled Acrobat as instructed, popped in the DVD of the new Acrobat Pro 9 that came in the box and up pops a message that every Mac users knows asking what I'd like to name the blank DVD and if I would like to mount it? That means the DVD is bank and never been burned. Confused I put it in my laptop with the same result! It was a blank DVD from Adobe!
    Looking at the back of the disk it was clear it had never been burned to, you can tell when a disk has an image on it or not.
    So thinking I'm clever I go to the download site to download a trail version of Acrobat Pro 9 thinking I could install it and when the question comes up to use it in trial mode to enter a serial number I could just enter the number and be done with it.
    So I followed the procedure and waited for the emailed link to tell me where to get my download from, 10 minutes later it showed up, I followed the link and the pull down option only showed 4 versions to download, all for Windows! I searched and searched and could not find a Mac version anywhere.
    Today I was able to get customer service on the phone who was glad to ship me another copy, they at firs suggested I just download the demo (just like I tried the night before) and I told them I could not get a link for the Mac. She put me on hold, then came back to the phone apologizing and telling me I was correct, there is no trial or download version of Acrobat Pro 9 for the Mac. I would have to wait for the replacement DVD.
    So to me the question is I would have a hard time believing there are more Acrobat Pro 9 versions on PC's than on Macs even though there are so many more PC users. I've never met a single Acrobat Pro user on a PC and I work in IT/MIS at several very large companies. Only the Mac people ever seem to want the pro version, sometimes a few PC users in Marketing or legal want the Regular Acrobat but not the Pro version.
    So Adobe why no Acrobat Pro downloads or trials for Mac users? Seems the long standing good relationship between Mac users and Adobe continues to be neglected and diminished. This is hardly the only item I've come across in the last few years where Adobe treats Mac users like secondhand users.

    What  extra work! two, three lines of extra code (may just one) to put a time limit in, that can be overridden with entering a bought serial number. Even shareware peopel do it.
    And I remeber when Acrobat only worked on Mac's. You see it was introduced to Mac's first. Microsoft wouldn't allow it until version 3 or 4.  If I still had my 7100/66 I might could prove was I one of the beta Testers. But that machine was traded in on the G4-500 (which I still own).
    Most major software companies will come out with a new application on the Mac first. Because Mac users tend tobe willing to try out something new on the cutting edge. Then when its prefected they come out with a PC version, and forget about the Mac community.
    Look I am 61. And I didn't just fall off the turnip truck yesterday. I've been around since before the days of the moden internet. I  started with Buliten Boards on 300 baud modem on an old fashion POTS line.  Cost me a fortune in Phonebills
    So don't discount my experiences so lightly. I've used appliactions such as ATM Aldus PageMaker (yes you heard right Aldus). I've use Word Perfect for Mac and PC back when it was owned by WordPefect, then Novell) I've use Microsoft works when it came out for the SE/30. Lotus 1-2-3 both on Mac and PC, FaxSTF, and other that are now none existent on the Mac. Chance are I was using Computers about the same as some of you and probabaly earlier than some. I lived it.

    When I send an email from Mac Mail, why does Mail go to the background and the Finder comes to the front? I want it to stay in Mail.

    Did you check your user name and password in Settings>Mail,Contacts,Calendars...tap your email account, tap SMTP, then tap the primary server name.  Make sure the settings there are correct.

  • Why can't I open and retrieve my files from iPhoto and my address book after importing the files from my Power mac G5 to my new Mac Pro? I get a warning that says the new OS on my Pro doesn't open files from a Power Mac. Any idea how I can fix this?

    Why can't I open and retrieve my files from iPhoto and my Address Book after importing the files from my Power Mac G5 to my new Mac Pro? I get a warning that says the new OS on my Pro doesn't open files from a Power Mac. Any idea how I can fix this?

    For your addressbook, export the files to vCard on the PowerMac, then bring them over to your Mac Pro. For your iPhoto, copy the Users -> yourname -> Pictures folder to your Desktop on the Mac Pro, and open iPhoto on the Mac Pro holding the command and option keys.  Select the library file from that Pictures folder and open it.  It should import all the pictures into iPhoto as part of the rebuild process.  Other PowerPC to Intel migration issues are covered here: https://discussions.apple.com/docs/DOC-2295

  • Why are my movies not showing on my Mac Book, which is the computer that I used to purchase the movie, but showing on my IMAC at home...I am currently deployed.

    why are my movies not showing on my Mac Book, which is the computer that I used to purchase the movie, but showing on my IMAC at home...I am currently deployed so this ***** a bit. Also how do I keep this incedent from happending in the future?

    No, this is not the case. I know where i purchased the movie and I also know movies cant be added to the cloud such as music, TV shows can.  The instance happened during the dowload. I think that depending which computer is up and running and the bandwith allocated on either network, which ever computer that finishes first is the one that gets the movie. Just a thought. So next time I will ensure my IMAC is not running. I think that fixes it.
    Thanks

    Apparently cookies was turned off in Safari. I rarely use it so I have no idea how that happened. Anyway, turning them on seems to have cured the problem.
