I let it rest one night, and the day after it starts with some crashes, but then alright. Sometimes it turned on (after many combinations of SMC and PRAM reset), sometimes not, but 99% of the time there were 3 beeps. Then, it has been a long journey of different problems: it crashed on login, or when there's the apple and the loading bar, then it did a single long beep. Three days ago, while i was downloading 3 files at the same time, my Mac crashed and started doing 3 beeps. They are two 4GB sticks that are linked below. The ram I used was a Corsair 2 x 204-pin SODIMM DDR3 1066 MHz CL7. I couldn't find any ".Panic" results under System Diagnostic Reports however. Here's what I got from searching for "shutdown" without the quotes in Console.appġ/3/15 3:10:31.844 PM locationd: locationd was started after an unclean shutdown 1/3/15 3:10:33.877 PM discoveryd: Basic DNSProxy DNSProxyServer has shutdown: DNSProxy listener sockets are now closed 1/3/15 4:00:18.435 PM shutdown: halt by _cvmsroot: 1/3/15 4:00:18.435 PM shutdown: SHUTDOWN_TIME: 1420329618 435189 1/3/15 4:00:18.436 PM : (.domain.system) System reboot initiated by: shutdown.2679<-sessionlogoutd.2675<-launchd.1 1/3/15 5:45:13.000 PM kernel: Previous shutdown cause: 5 1/3/15 5:45:36.078 PM discoveryd: Basic DNSProxy DNSProxyServer has shutdown: DNSProxy listener sockets are now closed 1/3/15 5:45:43.947 PM discoveryd: Basic DNSProxy DNSProxyServer has shutdown: DNSProxy listener sockets are now closed My MacBook ran like a champ from the day i got it in November 2011, but now I'm wondering whether there's a problem related to the motherboard? Or if the hard drive problem and the ram failure problem were somehow related and not a coincidence that both of those replacement had to be made around the same time? Needless to say it's been frustrating to be at the mercy of random crashes. So now I'm back to having those random crashes but this time they're much more unpredictable. But then as I tried to boot it up one morning, the screen turned grey and a flashing folder icon with a question mark in it appeared, so I took that in and it turned out to be a faulty hard drive bracket which I got fixed today in store.
For the first night it worked perfectly but the next day it began to randomly freeze and beep 3 times again.īy this time I had just finished my finals at school and I was able to manage using my MacBook sonlong as I didn't do anything that involves too many tasks that involved video and such. Upon booting back up, I would get the dreaded 3 beeps indicating ram failure (according to an employee at a Genius Bar visit) so I upgraded the RAM to 8gb from 4gb myself.
Background: my late 13" late 2011 MacBook Pro was randomly freezing and shutting down or restarting before freezing again and shutting down.
