Hey I bought my rMBP in july 2012, and ever since then it has been a lot of problems. So with the listed problems below; Can i return my computer? Safari loads extremly slow, only loads like 10% of the page up in the search field. It takes around 20-30 seconds for it to start loading again after the 10% stop. GIFs on internet glitches like ****. They lag, load slowly, and many times they flicker like crazy - going from first picture to second -> first picture to third etc. Makes it totally unwatchable. www.twitch.tv only works 1 out of 10 times. When i enter a stream i want to watch, the stream is completly black. And while i'm on www.twitch.tv problem no. 1 always occur when i try to open another page. Image retention. No explanation needed. Movies lags. Picture/sound is out of sync. Video stutters, then speeds up like the computer took an ecstacy pill for 3 seconds. Idle temperature is always 60+ degrees celcius. Dont know if this is standard though. Swapping through for example facebook pictures if glitchy aswell. What happens here is that when i go the next picture in a gallery, a part of the previous picture blocks the new picture. Text on some web pages is replaced with big white blocks. I guess it's when there's a flash text(?) And last, but not least - this retarded EFI update that ****ed up the whole computer. Making it unusable unless i dont shut it down and do a SMC reset.
