A hack to continue with Skype 6.3 on MacOS 10.5.8

Today Skype users on MacOS 10.5.8 were surprised again that Skype rejected the login and requested to upgrade to a new version. Navigating to the new version download announced once again:

This had happened in the past and the solutions then ranged from installing every old versions of Skype (2.8) to tampering with certain system settings, last year Skype released an officially supported version 6.3 for MacOS 10.5.8 but this only lasted until today.

So I tried various things and a variation of earlier solutions did it for me which I would like to share with the community. In summary: trick Skype into thinking that you are running a higher version than 6.3.

Change 3 settings in the info.plist file

  • First of all quit Skype so that no Skype process is running anymore
  • Open info.plist with the property editor (in Finder -> Applications choose Skype, right-mouse click and choose Show Package Contents, in the new window double-click on Contents and double-click on info.plist )
  • Change
    BuildMachineOSBuild 12F45
    Bundle versions string, short 6.15
    Bundle version
    The previous settings were for me and 12C3103.
  • Close the property editor and Save the file

    Change the /etc/hosts file

    This prevents that your network contacts the Skype download server.

  • Edit the /etc/hosts file (with your editor of choice)
  • Enter this line
  • Start Skype and login again

    There you go.
    Let's wait and see until this solution becomes obsolete.


    1. Thank you. Can you go a little more into detail concerning the etc/hosts-file change for those of us who have no idea what they're doing (maybe a screenshot or something?).

    2. Great! Many thanks from all PPC people!

    3. thanks thanks thanks

    4. Огромное спасибо!!!!! Thank you very much!!!!

    5. Hey all (especially the first commenter), here is a guide using Terminal, the editor that comes with the Mac:
      Be careful to follow all the directions, especially using TAB (no spaces!) to separate "" from ""

    6. It is still working! Great - no need to update to 10.6 (have several expensive programs that won't run on 10.6 or later)!

      Many thanks!

    7. Dear Andreas,

      I have a question associated with Skype usage on a macbook pro. Can you advice on how to solve the camera malfunctioning issue (the system profiler does not detect it anymore)? My iSight worked for about a year and then just stopped working. I tried different "solutions" posted on the web, but neither of them worked (PRAM resetting, iSightFix from codium, etc.). So I am currently using a third-party webcam.

      Looking forward to hearing from You,

    8. After making all the changes I get the message

      Skype can't connect

    9. same here... any solution?

    10. Thanks a lot !!!!!! I am using it again !!!!

    11. Thanks a lot! Now I got it working again on iMac G5.

    12. Good and superb app its very nice post... Visit :- Skype Technical Support Also Call +1-800-231-4635 USA (Toll Free).

    13. Rather use - if you run some sort of local server, then you don't want skype to permanently ask your server for spam.
