Apple is back at the top these days and while it’s mainly due to the iPod and iPhone the good old Mac is also getting a lot of love. More and more folks decide to use a Mac and while it’s fairly simple to root your Samsung Fascinate on Windows it’s a bit harder on a Mac so here are the instructions for a Mac as well as a video created by cjstreater.
Cory Streater @ the Android Central Forums released the instructions on how to root your Verizon Samsung Fascinate using a Mac from Apple.
Take a look at the following video on how to root your Samsung Fascinate device, you will also find the written instructions below:

To root your Samsung Fascinate, follow these instructions [from Rooting Using a Mac (Video Tutorial)]:
1.) Download the SDK from the above link and drag the contents to your Macintosh HD in finder.
2.) In Finder open up /android-sdk-mac_x86/tools, then extract the 4 files in the attached RAR to this folder.
3.) Open applications > go to Utilities > then open Terminal.
4.) Enlarge the Terminal window for easier viewing.
5.) If your Fascinate is plugged in to the Mac, unplug it now.
6.) On the Fascinate go to settings > applications > development and make sure USB debugging is checked.
7.) Plug the Fascinate into your Mac.
8.) From Terminal type the following (without the $ signs):
$ cd ..
$ cd ..
$ cd and*
$ cd tools
$ ./adb push su /sdcard/su
$ ./adb push busybox /sdcard/busybox
$ ./adb push rage.bin /data/local/tmp/rage.bin
$ ./adb shell
$ cd /data/local/tmp
$ chmod 0755 rage.bin
$ ./rage.bin
Wait for rage.bin to complete. When it's finished you should be back in the tools folder again as shown below.
Cory-Streaters-MacBook-Pro:tools cstreater$ ./adb shell
# mount -t rfs -o remount,rw /dev/block/stl9 /system
# cd /system/xbin
# cat /sdcard/su > su
# cat /sdcard/busybox > busybox
# chmod 4755 su
# chmod 4755 busybox
# exit
$ ./adb install superuser.apk .
You should see a message saying that superuser.apk was installed successfully.
9.) Reboot.
10.) Once booted you should see a Superuser icon in your app drawer.
