Fetch does not work in 64-bit mode Mac OS X 10.6.2 (5 posts)

    I tried to run Mac OS X 10.6.2 in 64-bit mode (opt-cmd-6-4 during boot up), but Fetch hangs when it tries to launch. It works fine if it runs in 32-bit mode. Any fixes?

    Hi,

    Fetch is a 32-bit app, so it won't run in 64-bit mode. Is there some reason you want to run in 64-bit-only mode?

    Thanks,

    I did a bit more research, and see that holding down 6 and 4 during boot gives you the 64-bit kernel. But I did not have any trouble running Fetch 5.5.3 after booting into the 64-bit kernel on my MacBook Pro, so it appears that 32-bit apps like Fetch are still supported.

    One thing that isn't supported under the 64-bit kernel is 32-bit kernel extensions. Is it possible that you have any of those installed?

    Thanks,

    Hello,

    On the topic of 64 vs 32 bit, I've been told by our FTP host that it is NOT POSSIBLE to transfer files larger than 2GB on boxes running 32 bit os and software, in other words only 64 bit os AND 64 bit FTP clients can. What is your opinion of this claim?

    Thanks!

    Hi Steve,

    I think that claim is incorrect. As it happens, I transferred a 4.4GB file between Fetch (a 32-bit app) and a Mac OS X 10.5 machine running on a 32-bit kernel just yesterday.

    The confusion comes from the fact that the term "32-bit" can apply to different things. Fetch is a 32-bit app in the sense that it uses 32-bit values to refer to data in RAM. But it keeps track of file lengths using 64-bit values, so it will happily transfer files that are longer than 4GB.

    Macs gained the ability to work with files larger than 2GB a long time ago, even before Mac OS X was released in 2001. I believe that Windows did so as well, around the same time. So it should not require a particularly modern OS to be able to transfer such files.

    I hope this helps,
