No idea if this is any help at all, but I run two versions of Apple Pages (I have my reasons… ;-)
I have the older version set as the default for all Pages documents, and make exceptions when I need to. Interestingly, MacOS 10.13.6 gets confused sometimes. Even if a document is set to open with the newer version, some launch the older version. Can’t always see why. They also always open with the older version, if that version is already open, irrespective of the setting in Get Info. Except if you use “open with” 8.1, then the later version is launched and used. I have also noticed that some docs are set to open with the older version with the text in the get info 'open with' drop down menu saying Pages (Default) (4.3) Whereas others just say Pages (4.3) I can’t work out if there is a difference between the two, but the drop down menu also normally offers Pages (Default) (8.1) Which is only effective if 4.3 is not open So this looks like a dark art not even the Apple Developers have mastered. Although I guess they would argue that no one in their right minds runs more than one version of the same app. Cheers, David G > On 7 Aug 2019, at 3:10 am, Mark Waddingham via use-livecode > <use-livecode@lists.runrev.com> wrote: > > On 2019-08-06 23:59, Paul Dupuis via use-livecode wrote: >> For example, if you drag installed 5 apps, APP1, 2, 3, etc, that all >> had a info.plist defintion for a .xyz file extension onto a virgin OSX >> system out of the box and then double-clicked a .wyz file, which of >> the 5 would open? > > I *think* the answer to this question probably lies here: > > https://developer.apple.com/library/archive/documentation/Carbon/Conceptual/LaunchServicesConcepts/LSCConcepts/LSCConcepts.html#//apple_ref/doc/uid/TP30000999-CH202-TP9 > > The sections on 'Application Registration' and 'Preferred Applications' are > probably the most pertinent - although it isn't entirely clear how the two > mechanisms co-exist: registration suggests the 'most recent' modification > time wise app is stored against a file kind, but preferred applications > suggests that multiple apps are stored but the newest CFBundleVersion wise is > chosen. > > Warmest Regards, > > Mark. > > -- > Mark Waddingham ~ m...@livecode.com ~ http://www.livecode.com/ > LiveCode: Everyone can create apps > > _______________________________________________ > use-livecode mailing list > use-livecode@lists.runrev.com > Please visit this url to subscribe, unsubscribe and manage your subscription > preferences: > http://lists.runrev.com/mailman/listinfo/use-livecode _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
