Hey guys I just received my macbook pro back from an apple repair. They replaced my logic board with another one but now its either extremely slow or not responsive at all. Is this normal? I upgraded all my softwares to Yosemite and still get the constant freezing. I can't even open a program without running into the spinning rainbow ball of torture. Has anyone ran into this problem?

Not normal, but SMC reset has been known to fix some issues relating to slow systems. Might need two or three resets to actually get results.

They should have done an SMC reset when they installed the FRU, but they are only human, after all, and nobody is perfect.

Did they change anything else?

Do you have a HDD or SSD? Drives don't last forever, so perhaps your one is failing or perhaps the SATA cable got damaged during the logic board swap.

Perhaps try the SMC reset first, then you could run a HDD / SSD benchmark and compare with results for similar drives.

I tried resetting it three times, but still everything is slower than it was before. Opening multiple programs still brings up the spinning rainbow and my music sounds fade in and out

I have the same issues... Logic board replaced twice, RAM replaced, and new display. Apple told me that it's due to software... I feel your pain :(

Could be another crappy logic board too, or something else (software-related included.)

I'd contact them again and tell them what's going on. Better to have the troubleshooting documented by them as you go rather than having to possibly redo it all just for them.

In the meantime, I would run a full diagnostics through AHT overnight or weekend.
