Hi,
I'm creating a new package for some software that has been updated.
I'd like the new package to be able to upgrade a previously installed
version.
I can only get Installer.app to show me an Upgrade button instead of an
Install button if the .pkg wrapper has the same name as the old
package. Unfortunately, my old package had a version number in the
filename, and I don't want to release the new version of the .pkg with
the old version number in the filename!!
Is there any other way to achieve this? There must be, since
iTunes4.pkg will show an Upgrade button for upgrading iTunes3.pkg...
mind you, iTunes4.pkg is a 10.1-style .pkg I think, since it has an
"iTunes4.pre_upgrade" script rather than a "preupgrade" script as is
used in 10.2-style packages.
I'd be happy to make a 10.1-style package if that meant I wouldn't have
to give the package filename the wrong filename, assuming a 10.1-style
package could Upgrade a 10.2-style package, but I don't have any 10.1
machines around so that would be quite inconvenient....
Anyone? Pretty Please with Cherries on top?! :-)
Thanks for your help,
Jim
