ok so today i was trying to change the look of my menubar icons. the ones i found, they came with an installer, so i just installed them. my laptop told me to log out, so i did. when i logged back in, my computer no longer worked. no programs will open, they bounce and crash. and the menu bar is bascially gone, except for a few shadows. i've tried to repair the disks using command s and everytime i do, it tells me my computer is fine, when it clearly isn't. the last time i backed up with time machine was probably a month and a half ago. :/ is there is any possible way to fix this problem without time machine or reinstalling the whole operating system? i am so screwed, please, please help.
