    I have owned many Apple computers in the past years! But I'd dare to say the Mac mini is the worst Apple product ever! I bought the late 2012 Mac mini 2 years ago, have always been crashing randomly! Sometimes finder would freeze completely and the death spinning circle will pop out and I will have to hard reboot the computer! And just this evening, it crashed again! This time I managed to copy the error code! Could someone here help me out and tell me what might have caused the Mac mini go crash?? Thank you so much everyone!!

    Based on com.realtek.driver.RtWlanU from the log, it seems like you're using some USB WiFi adapter with a Realtek chip in it. Start by looking for a new driver or remove it.
