Any else having this VERY frustrating problem of Safari and Mail not opening. I've installed Snow Leopard and downloaded and installed the 10.6.1 update. Then when I try to open Safari, it says, "You can't use this version of the application Safari with this version of Mac OS X. You have Safari 4.0.3." When I try to open Mail, it says the same thing. I downloaded Safari again, and it won't even install it saying, "Safari can't be installed on this disk. This update requires Mac OS X 10.5.8 or newer." But I have 10.6.1.

Help. Anyone? Please?


MacBook, Mac OS X (10.6)

    Try launching Safari and Mail from the Applications folder. If it works, drag the Safari and Mail icons off the Dock. Just drag straight up. They'll go poof.

    With Safari or Mail open, select the icon in the Dock/Keep in Dock.

    If that doesn't help, locate these files.



    Drag those files to the Trash, empty the Trash and restart your Mac.

    Thank you! That was helpful. In doing the dragging around, I discovered I was trying to open the pre-Snow Leopard copies. Everything's working now. thanks for responding.

    Hi Carolyn,
    I'm having the same problem with Snow Leopard (10.6.1) with Mail.
    Keeps saying "You can't use this version of the application Email with this version of Mac OSX. You have Email 3.6."
    How exactly do I locate this file....'com.apple.Mail.plist'
  • sphilli Level 1 Level 1
    There should be a separate "Mail" application that comes with Snow Leopard. That one should open fine. My problem was I kept trying to open the pre-Snow Leopard Mail ap, and that's when I get the error message. When I threw out the old app and launched the new one, everything worked fine.

    Hope that helps.

    I can't locate the file previously spoken of: "com.appple.Safari/plist"
    Does anyone know how to find it?

    The file should be at /Users/username/Library/Preferences/

    Just an FYI, I trashed the file like the thread said to and I still can't open the app

    Hey all! I just got off the phone with Apple Care and we were able to resolve my problem of Mail not opening (version errors).

    I initially, following the device of this thread, deleted com.Apple.mail.plist, but that did no good.

    *What needs to be done (at least for me):*

    Drag Mail.app to the Trash and delete it

    Pop in your Snow Leopard DVD

    Choose Optional Installs

    Install Mail.app


    Open Mail

    I was able to resolve my issues by opening the Mail app with no issues and then it updated, the Safari browser then opened fine and has worked ever since.
