[q] i need major help!! Need to reinstall os on galaxy s5 with mac!! topic

Sorry for the caps, but I have been trying to figure this out for the past 48 hours. I woke up the other day with an update for CM11, updated it and found myself with no access what so ever to google play services. So, being the genius that I am, I went into TWRP-->Wipe-->Advanced Wipe and I wiped everything, Dalvik Cache, System, Data, Internal Storage, Cache, Micro SDcard & USB Storage. Turns out doing this deletes EVERYTHING. The only thing I have left on my phone in Download mode and TWRP Recovery where it notifies me that there is no OS installed. ADB Side loading is NOT an option. I also only have access to a Mac computer, forcing me to use JOdin instead of Odin. The problem I am running in to from here is that JOdin needs a .pit file (yay). I have downloaded the G900W8 pit file from here: http://forum.xda-developers.com/show....php?t=2737448 as I cannot manually extract the pit file, but when I use it in JOdin it tells me the file is corrupt. I have tried finding another pit file for my device but I cannot find one anywhere! Another problem I have run in to is with the firmware itself. I downloaded the firmware from here: http://www.sammobile.com/firmwares/d...1ANF3_BMC.zip/ and it downloads as a .zip but i need it in the format of an MD5 file. Now, when I extract the zip file it extracts in to a MD5 file halfway through extraction, and then it expands in to a full folder with no MD5 file. If someone could help me with this it would be greatly appreciated! Also, did i brick my phone?
