This has to be the first time in over 16 years that having a Mac has become a frustrating experience for me. Lion has very much ruined my computer for good. Here is a brief outline of how things have gone so far: - Before Lion was released, my computer was running perfectly for more than a year under Snow Leopard. No bugs, no crashes or slowdowns, no random black screen either. All was working fine. - When Lion was released I downloaded it and installed it without issue. I made an install over my previous Snow Leopard install. - As I started using Lion I began to experience slowdowns and the random black screen of death bug (which in my book is the most annoying thing ever). - Searching for solutions, I was told that the NVIDIA drivers were buggy under Lion, and was recommenced to install the CUDA drivers, to see if it helped. It didn't, I continued to experience the BSOD (Black Screen of Death). - Later on, I came across the tip of using the gfxCardStatus app to force the machine to use the integrated as opposed to the dedicated card. But the app kept switching back to dedicated and sometimes refused to switch to integrated and thus the BSOD persisted. - Then I found another tip, which said to delete from the Library/Preferences/ByHost folder any file named "windowserver" and then restart the machine, to help deal with the BSOD. It didn't work, the problem persisted. - Then Apple released Lion 10.7.1 and 10.7.2, and neither update fixed the problem. - Frustrated with this issue, and seeing how it was only until I installed Lion that I was experiencing this problem, I decided to back up my files, format my drive and make a clean install of Snow Leopard hoping that it would go way. It didn't, the problem persisted and this is because, it seems, Lion makes an update in the firmware, and so the change is set in stone, as it were, in the computer. Recently, Apple Released the Macbook Pro Video Update, which is aimed at addressing this very problem. Yet, it needs OS 10.7.2. Being under Snow Leopard and still with the problem, I decided to back up my files again, format my drive and make a clean install of Lion from a bootable DVD (not on top of SL). After updating everything in Lion up to 10.7.2, I downloaded and applied the Video Update and restarted. Not much later, I get the BSOD, the problem persists. Afterwards I restarted the computer in safe mode, repaired permissions, reseted the pram, etc all in the hope to see if something, anything, would fix the problem but no. Since I installed Lion in my computer, I seem to be stuck with the BSOD bug for good. Apple messed up big time on this one. Now I am stuck with a $2000+ computer only a year and a half old, which, thanks to Apple's latest OS update has become unreliable, if not frustrating to use. As it is now, I can't use this computer in a work environment anymore, as I had been doing prior to installing Lion. It will randomly black out on me while I am either working on Fireworks, CSSEdit, Transmit (has corrupted a couple of CSS files already blacking out in the middle of an upload) or even Chrome. The computer will even randomly black out when scrolling a Pages document or making QuickLook full screen. The problem happens totally randomly, making me be in constant fear of my computer blacking out after the next mouse click I make. I love Apple as much as the next guy but I just can't use a computer like that.
