Mac Client Crashing, Now all It does Is "Calculate Diffrences"

To whom ever this may concern I am experiencing Many difficulties with my league client for mac. If am long winded I apologize but this is a long series of problematic events. To start a couple of days ago I logged on to play as per usual everything was fine game was running smooth and all. Then in one game for no apparent reason I bug splatted, never had this happen anyhow i reconnected the game took a while to reload which was a bit unusual. Anyhow i connected and finished the game. I went to play one more game qued up and got into a match when the loading screen appeared i bug splatted again but this time could NOT connect to the game. I did everything from restarting League and my computer multiple times did not work which frustrated me because my friends had to ff at 20 because I was out. Anyhow I went into a custom match and the SAME thing happened. So now I'm flustered and started google for answers to no avail. I tried to use the "repair" function which got stuck the first go around so I rebooted and started Lol up and left it to do its thing. Finally finished and I launched the game. Went into a custom to test it out and reset my configurations, and nothing game quit and bug splatted again. So now I'm red hot with anger and frustration. I look on this site and tried all the possible quick fixes, foreced a repatch, made sure I had admin rights(I am the only admin on this laptop), I deleted the files that it told me to it would sit their and say calculating differences for a long time. finally after restarting the client multiple times it worked and re patched. Launched it and same thing happened in a custom. So i rebooted and tried again, then i get a prompt on the patcher "possible files corrupted would you like to repair" so i repaired AGAIN and let it do its thing. Now when i click launch I hear the noise but the login window never comes up there is no process of league ruining in the activity what so ever its like it just closes itself and or fails to launch at all. I have Yosemite OS X the latest version, I own a mid 2012 Mac Book pro with a 2.5 ghz I5 processor and 4 gb of ram. I have not updated nor downloaded anything recently nor have I not done anything out of the usual or experienced any problems with any other functions on my computer. I have also reset my SMC and Vram which did not help either. I have reinstalled league and just deleted the whole program and doing a fresh reinstall as I type this. I have also tried fixing my disk using the disk utility, verified permissions and repaired them, also verified the disk and repaired it as well. The disk utility now tells me everything appears to be OK everything i run it. I though it might be an OS problem so i reinstalled Yosemite, no luck what so ever. I even called apple and did multiple disk tests and while on the phone emailed the tech my logs for my Hard drive and he said everything looks ok so I'm pretty sure it is not my hard drive.Also my internet connection is great I'm the only one on my network and It is wpa2 secured also all the ports for league are forwarded correctly to from the instructions I followed from this site, also I have no in game ping problems and before all this happened league always updated quick and with no errors. Anyhow on a more personal note I am very upset, I feel like the mac client is not on the same priority level as the Pc client, and I know the majority of your players play on Pcs and all. I might just be saying things in anger but there ARE people who play on macs, and yes macs are not dedicated gaming computers but they are very much capable of handling most modern pc games to a certain extent. I use my computer for work, school, and entertainment on my down time ie: play league. I understand as well as great as apple computers are they are very finicky machines and coding for them is not optimal when it comes to video games anyhow that being said I really need help I am unable to play League now I will let you know when this reinstall is complete if anything changes but for now if there is anything you guys could do I would really appreciate it. At the moment my patcher has an affinity with calculating differences and scanning files....I feel like it is looking for something the isnt in the files that used to be there last patch or something...Bump this guys if you suffer from the same issue... Im at such a loss 0_0 sadness
