RPL, not sure exactly what your question is. Don't know what MLO has
to do with a Macbook Air, since MLO doesn't run on MacOS. Can you
clarify?
As for the comments from kitus and Nuzenn, as much as I'd love to see
a version for MacOS as well, there's been no statement that MacOS will
ever be supported. Judging by watching for forum for a while, there's
not a lot of demand for it currently. Such is world of capitalism. I'm
sure Andrey would consider making a version if you paid for the
development of it, but I'd guess that would be thousands of $/€/£...
Things and Omnifocus and many other native MacOS apps are great.
They've even got iphone and ipad versions. Why not go for them? What's
your goal in whining about MLO not being ported to the Mac? If you
like MLO, well then it runs on Windows, iOS, Android, etc. If you want
something that runs on a Mac, I'd suggest running MLO via Crossover
(aka WINE) or via Parallels / VMware. If you want a native app,
there's a rich market of alternatives all with their pros and cons.
Things and Omnifocus don't support the same features as MLO. So each
has to make their own choice about what app is best for them.
I'm surprised at the number of people that don't get software
development and market forces. Choose a piece of software that does
what you want now. Waiting for future developments is foolish and
futile and annoying for the rest of us to read your whining on the
forums. If you don't like it, choose an alternative. Or alternately
put in a feature request, and hope that there's enough others in the
world who also want it, then wait months or years for development to
possibly be done, and hope that when it's done it'll have the
functionality you really want.
If you want the world to work differently, then write your own code,
or pay someone to write exactly what you want.
