Run Mac OS X Apps On Linux?

I have the urge to commit my 24" Core 2 Duo iMac to a single Linux operating system, thus giving up the goodness of my beloved Mac OS X. I am not a stranger to Linux, but I am a stranger to running Mac apps on Linux. On my PowerPC I can use SheepShaver to run Classic apps. The Mac-on-Linux project can run OS X apps, but it requires a PowerPC, not an x86. Virtualizing and emulating are inefficient, especially given the wonderful results the WINE project has had in getting Windows apps to run on Linux. What I would like is an equivalent: a software compatibility layer that will allow Linux to run Mac OS X apps at native performance. I believe there is some additional complexity in accomplishing this. Mac OS X apps aren't just Mac OS X apps. They are Carbon. They are Cocoa. They are universal binaries. They are PPC code with Altivec. Does such a project exist yet? If not, why not?

I'm in the same situation. For 99% of what I do, MacOSX is a flaky pain in the neck. I'd love to be able to confine MacOSX to a window. Here is my background:

I've run *nix on the desktop for roughly 17 years. Last year, after we had a baby and I had essentially no time, I finally got tired of maintaining my system, and thought the "just works" aspect of MacOSX might be a nice change. I've been running 10.4.x on my Core 2 Duo iMac since last October. I've found that after more than a decade and a half of being able to customize my desktop behavior, I just can't adjust to the MacOSX gui. I hate the menu bar at the top, I hate not being able to define *MY* hotkeys for resize, move, and iconify, I miss the easy X11 1-click cut and 1-click paste, etc. To get around some of this, I run most of my shells via xterm. However, X locks solid every few weeks (usually when I scroll too much or too fast in some window).

I also find that the only MacOSX application I ever use is iTunes. I started out using Mail and Safari, but I moved back to Thunderbird and Firefox for the plugins. Specifically, the external editor plugin for Thunderbird so that I can edit messages in xemacs, and the noscript and adbplockplus extensions for Thunderbird.

I also hate that my 4 USBserial connectors are flaky, and have to be re-plugged before they'll all show up on boot. Neither Linux nor FreeBSD had this problem.

At any rate, how is the codeweavers support for playing iTunes videos? That's really the only thing I use iTunes for is video.

I'd have to ask what environment you write code in. I find that Xcode on OS X is one of the best environments that I've ever developed in, there are a few things about the IDE that bother me, but it's great overall and is getting better with each new release, and designing websites is really where OS X shines.
I can agree with you on Linux being an easier to use server platform, but OS X runs almost all of the same tools so that may change if I used it as a server more often.

Re:iTunes

Because if your iPod has a nervous breakdown -- and there is a good chance it will -- only iTunes as the "Restore" button. Amarok can't restore a corrupt database and wil just refuse to work with the iPod. Time for a trip to the Apple store.

Now, if there is a nice FOSS "iPod Restore" tool, that would help. Integration into Amarok as a plugin or something would be even better.

A wine-like system for OSX would actually be a lot easier to accomplish...
There is already something iBCS, which lets Linux run binaries from other x86 unix-like systems (SCO, Xenix etc... old stuff), and various BSD's have the ability to execute Linux binaries...
You only need to emulate the kernel interfaces, and then the user mode programs/libraries should run atop a Linux kernel just like they run on OSX's existing kernel. Then you can begin reimplementing the proprietary libraries one by one. Those libraries which are BSD licensed you can directly port the source.
All in all, a much easier job than wine.

Linux on Mac

[rev_karol]

I put Ubuntu on my macbook recently and was seriously impressed. Really looks up to scratch for the desktop. First off, pretty much everything worked without too much googling. Picked up the graphics, sound, wireless, etc., no problem. I read I can get the webcam working quite easily too. The only thing I didn't try was the dual screen/extended desktop. The compiz stuff worked as soon as I turned it on (I'd miss exposé otherwise). I have a usb tv-receiver that won't work but I expected that since it's built for Mac. It was the responsiveness that really got me though, Ubuntu was far snappier than OSX (and I've 2GB of memory) - Mac apps like to think about things for a while sometimes (and they're not using the CPU to think, whatever the hell they're doing).

There are a couple of Mac apps I'd miss. Number one is Omnigraffle. Really handy for making diagrams. There's nothing close on linux as far as I can see (although I've just tried the OpenOffice Draw program and there's potential there). Second one is Keynote. OSX also has PDF built in as a native format, which is really nice, and the drag and drop support is unparalleled.

I use Linux in a virtual machine on Mac for college. It's about a 2GB code base (or something ridiculous) so I won't be trying to recompile for mac any time soon. It works, but native would be much nicer.

I think the Apple hardware is pretty decent. They cram a lot of good stuff into a small space. I've been hard pressed to get all the same features in a Dell for the same price last time I tried (and it's usually twice the size/weight).

So I think Linux on Mac makes sense for some of us.
