App not opening on mac [Client] [Crash]

Every time I go to start the app the initial logo comes up for a quick second then completely goes away. Client crashes. I have uninstalled and reinstalled several times. Restarted computer, reset router etc. just to be safe but I keep having the same problem.

In the client log the error message seems to be the same even after each time I reinstall: (entire file is attached too) ( DEBUG)[10:47:15.000] HRESULT RADS::Common::HTTPConnection::GetFile(const std::string &, const std::string &, RADS::Common::IGetFileProgressCallback *const, const bool, const bool, bool, std::vector *): ("/releases/Maclive/system/filelist.versioninfo", "/Applications/League of Legends.app/Contents/LoL/RADS/system/temp/filelist.versioninfo", RETRY, 0x00000000) ( ERROR)[10:47:18.000] HRESULT RADS::Common::HTTPConnection::GetFile(const std::string &, const std::string &, RADS::Common::IGetFileProgressCallback *const, const bool, const bool, bool, std::vector *): perform request failed with code 6
