(So the mac has frozen two times while attempting to write this message - on the phone now - hopefully this freezing bug is not contagious :D) Hello guys, My mac has started to freeze since the last 3/4 days. After the cursor freezes, 50 percent of the time with the rainbow scroll, I close the lid of the laptop and the screen light turns off(I can see from the logo). When I immediately reopen, either a scrambled screen comes, or the laptop seems to restart. When this happens it goes to a flashing question mark folder most of the time or a white screen. I then force restart with the power button and laptop boots up as usual. The first times it seemed to happen when the mac i felt was under load, e.g first time was when football manager was open with a number of safari tabs as well. It also happened when I was scrolling reddit, when i sometimes get a safari notification saying reddit is taking siginificant memory. However this issue has migrated to instances when there is no load. In the past hour the mac has had this issue 2 times, when the only thing running was safari and the ifixit tab. (Although i had attempted to write these messages straight after rebooting from a crash). Also in the last crash, i got a message before logging onto computer of a “the system is unable to unlock your login keychain - login keychain is damaged, cannot be used, new one created. Does this suggest an access to memory problems, as I also get the flashing question mark folder occasionally? Does what I am observing seem to match a common symptom, and if so, is there a potential fix? Many thanks in advance…

I’m not sure if your logic board its self is having a problem or your SSD. I would setup an external bootable drive so you can run disk utility on your internal drive to check it out for corruption. You may also need to delete some stuff from your drive as it maybe to full! You really need 1/3 of the drive left unused on the smaller sized SSD’s (256 GB or smaller) and 1/4 on 512 GB and larger. At this point I think you’ll need to do a bit of inspection to see if you have corrosion damage and/or if your system needs some cleaning of dust and maybe need the thermal paste refreshed given its age. You need to look on both sides. Here’s the guide you’ll need to follow MacBook Air 13" Mid 2012 Logic Board Replacement
