BlackBerry Desktop Manager for Mac hit the airwaves recently, and we’ve seen no shortage of reviews. The application is pretty straight forward, though it lacks a few features of the PC version. One is the ability to install unofficial OS upgrades. But, like all things Berry, someone has created a workaround. The following video shows you how to get around the problem of having a .exe OS file on a Mac that doesn’t run the file type. After the jump, OS 5.0 links, so you can test it yourself.
8900 – 5.0.0.238
9000 – 5.0.0.238
9530 – 5.0.0.230
9630 – 5.0.0.230 Once again, we must disclaim that these are unofficial operating system files, and they may cause unexpected errors and malfunctions to your BlackBerry. Be sure you have a backup in place, just in case you need to wipe your device and start over again.

I was using .297 from AT&T and i followed this steps to install the 5.0.0.238 on my Bold.
After loading the official OS there was no problem at all. The problem came when i loaded the .238 files and Desktop Manager for Mac tried to load the OS again. After rebooting the phone i got a blank screen with a list of all my applications and the first time configuration wizard on top. When i clicked continue it just hung up. And from now on it just gets stuck in that screen.
I’m downloading the 238 version for Windows. i will wipe the device and load it from there.
now if someone could do the same for windows desktop manager
