[MAC] LoLLauncher Won't Load

Ok, this is a really confusing problem that I've come across while trying to play league. I've re-installed League several times, both for the Brasil servers and the North American servers, but the launcher still won't even show up for me. Here's what happens: I click on league of legends in my dock to start up the patcher or launcher or whatever you want to call it. The LoL logo then pops up like usual, but it takes longer for it to disappear than normal. After that, UserKernel comes up on my dock, but it also takes longer than usual to disappear and change into LoLLauncher. Once the LoLLauncher shows up on the dock, however, the actual launcher won't appear on my screen. A single tiny white dot does appear right in the middle of my screen, but besides that there's no way for me to tell that there's any window open at all. I haven't been able to fix this at all, and it started around the time that the 5.4 patch came out. I have no idea if that patch caused the problem, but I would assume not because I hadn't installed it yet. I'm also not able to get a crash report, because it doesn't crash, it just stays unopened. If anyone needs additional information, just comment here because I really want to start playing league again.
