I have an app that only exists a 32bit version. In order to use it, I used to press
3 together before booting the Mac, so it'll run in 32bit mode. However, some apps (64bit version that installed before) will always crash in this mode..
I happened to see a solution that run 32bit app in 64bit system:
arch -i386 theApp.app
But I tried with
arch: /Applications/theApp.app isn't executable error. I checked the file permission and it shown
drwxrwxr-x, it should be executable, uh?
EDIT: As @gd1 said, theApp.app is a folder(it's called bundle in OSX I think) and so it is not executable.
But I still need a workaround:
How can I run my 32-bit app in my 64-bit system correctly?
EDIT: I can open the app with
arch now with the command(thanks @GordonDavisson):
arch -i386 /Applications/theApp.app/Contents/MacOS/theApp
However, the app run with
Components lost error, log shown below:

It seems it's 32-bit only & depends on the 32-bit kernel. Oh, I'm sooo sad. :(
Here're some infos I got with the help from @GordonDavisson, maybe someone else need it.
The DOC shows some methods to temporarily start up with the 32-bit kernel to use older kernel extensions for the third-party software or hardware.
And it is about "Compatibility with the 64-bit kernel":
Third-party software (such as a virtualization engine) or hardware (such as a PCIe card) that relies on a kernel extension which was compatible with Mac OS X Server v10.5 may not work on Macs that use the 64-bit kernel in Mac OS X v10.6. Contact the software or hardware vendor for an updated kernel extension that works with the 64-bit kernel in Mac OS X Server v10.6.
As a workaround, you can temporarily start up with the 32-bit kernel to use older kernel extensions for your third-party software or hardware.
