Currently there is no method to unroot your Galaxy S4 on both Mac or Linux. Luckily Chainfire has recently updated his app to support the Galaxy S4 line up so now you don't need a computer.
With Mobile Odin you can completely unroot your Galaxy S4 without ever needing a computer as long as your were rooted prior to using the app. Very useful is you only own a Mac or Linux based computer or if you just can't get your hands on a Windows computer.
Mobile Odin supports multiple types of Galaxy S4s including: GT-i9505, T-Mobile SGH-M919, Sprint SPH-L720, US Cellular SCH-R970, and Canada SGH-i337M variants.
If your are planning on sending your phone back to your carrier/Samsung make sure you reset flash counter first!
Just follow the step-by-step directions down below and you will be unrooted shortly!
1. Download Mobile Odin from the Play Store to support the developer or download the free version from XDA. I HIGHLY recommend you download the paid version from the Play Store!
2. Download the correct stock tar file using the link below and transfer it to your phone. Note: You may need to unzip the file to get to "tar.md5" stock file.
Download stock files for the Galaxy S4 for your specific model
3. Open Mobile Odin and grant SuperSU Request.
4. Download the add-on files.
5. Scroll down and select "Open file...". Locate and select the tar.md5 stock file you downloaded in step 2.
6. Then uncheck "Enable EverRoot".
7. Check mark "Wipe data and cache" and "Wipe Dalvik cache".
8. Select "Flash firmware" and continue. Also select "Check" to MD5 signatures.
9. You will automatically be booted into "Download Mode" with the green Android. Press and hold the power button for 10 seconds. You phone will automatically turn back on and in 10-20 seconds you will see a blue Android.
10. Wait for the blue Mobile Odin to finish in about 5 minutes.
11. Once the process is complete you will be booted into stock recovery. Select "wipe data/factory reset" and "yes".
12. Then select "wipe cache partition". Then your phone will automatically reboot.
13. After 10 minutes you will be fully booted up and unrooted!

With the latest Samsung flagship devices whenever you flash a custom firmware your phone automatically triggers a flash counter letting Samsung know you modified your Galaxy S4 device. Even if you try to unroot your phone the counter will still stay their.
But, with the Triangle Away app made by Chainfire you set the counter back to 0!
Currently the Triangle Away app supports the Galaxy S4 GT-i9505, T-Mobile SGH-M919, AT&T SGH-I337, Verizon SCH-I545, Sprint SPH-L720, US Cellular SCH-R970, and Canada SGH-I337M. Currently it DOES NOT support the GT-i9500!
If you are attempting this on a AT&T or Verizon Galaxy S4 you need to have an unlocked bootloader!
You MUST be running on stock Samsung Kernel and rooted!!
1. Download Triangle Away app using the link below from the XDA forums directly to your phone.
