Tldr Early 2011 Macbook Pro acting unusual with memory usage and freezing with three beeps. But how is this issue only happening when the machine is running in battery.Īny thoughts on what could be the issue? Thank you! Searching through forums and apple support tells me that 3 beeps are an indication of RAM failure/misalignment. And there are no other trustworthy repair shops in small town I'm in. Apple store guys here won't even diagnose it.

Now the trouble is being a 2011 'vintage' model. As soon as I placed with closed lid, three beeps sound is here again. Kept it on for about 45 mins and nothing happened – was on direct power all this while.īut then I removed MagSafe and picked it from one desk to place it side shelf. Now today, just to try and replicate the issue I kept the machine on with iTunes playing in the background and a long iMovie video render. I noticed one pattern that both these times It was running on battery and not direct power. Next day I kept working on it cautiously and then again it froze, this time without any beeping sound.

I took all the back up, fixed permissions, rebuilt cache and did all other basic maintenance via Onyx along with SMC, PRAM reset.Īfter all this, the unusual memory activity stopped but in few hours it made a repetitive three beep sound and completely froze. I suspected may Adobe is the culprit here but next day it happened with a different app and so on. By going to Activity monitor I could see photoshop consuming 64GB! of memory – which was unusual.
