I picked up a hires antiglare late 2011 15" MBP late last year. It was new in box at Microcenter for $200 less than refurbs were costing on apple.com. I was so happy. Then I put Mountain Lion on the thing. I also put in 8 GB of RAM but got greedy and put in 16 GB of RAM. I have been having app crashes and kernel panics since day one. With 10.8.1 I lost crashplan and I lost the ability to reorder checks from my bank due to Apple's little Java war. I would come into my office and find the fans running full blast with Java using 600% of CPU and 12 GB of memory. I would quit Java and it would relaunch and work for "another few days." With 10.8.2, things started working better but I still got the occasional crashed app, especially iPhoto. When 10.8.3 came out, I hesitated for a few weeks but finally gave in and let it upgrade. That was the beginning of the end. My fans came on and never went off. I was the victim of a reportcrash loop (posted elsewhere). The AppleCare guys convinced me to reset SMC, clear PRAM and finally reinstall OSX 10.8. While my problem is resolved, as I look back on my ownership experience with my MBP, I have had more problems in 5 months of ownership than I had in 5 years of ownership of my 2008 White Macbook. I said out loud more than once to the Apple guys on the phone that if they couldn't help me figure this out soon, I was going to have to consider turning to Dell or HP. Hence the title of this thread. So what was the lemon here? Was the hardware badly designed in that it couldn't tolerate a little extra heat from 16 GB of RAM versus 8GB? Was the OS bad in that it was unstable? I have 10.8.something on my Mac mini and it has never batted an eye. Was it my fault for pushing the limits and putting in 16GB against Apple's recommendation? Even Crucial now lists 16 GB as a supported upgrade for my machine these days (MacBookPro8,2) Here is a list of apps that have crashed: * crashplan - almost daily due to JVM issues * Time Machine - stopped working properly at about 10.8.1 * iPhoto - crashed on almost every launch (with 300+ GB of photos, 1,000+ events, 10,000+ photos in faces and 500+ photos in places) * mail.app - crashed more than once a month * chrome - crashed more than once a week - despite click to play and flashblock * preview - occasional crashes * OSX - found OSX rebooted itself overnight without explanation - 10 times in 5 months - starting with 10.8.1 * finder / totalfinder - crashed more than once a month * eyefi helper - infrequent but random crashes which unpredictably prevented dslr photos from showing up on my Mac where they belong I would think Apple engineering is sick of crash reports (accompanied by my increasingly sarcastic comments) from my MBP by now! Apps I've used often and had no trouble with at all: * Numbers * Pages * LibreOffice * Seashore Here was my procedure migrating from my white Macbook to my MBP: 1 - boot whitebook in target mode 2 - tell MBP to migrate over firewire from white macbook 3 - download Mountain Lion (previously purchased for my Mac mini) 4 - create ML USB stick (boy did THIS save my life later) 5 - Allow ML to install 6 - start new TM backup to 2TB usb disk on gen 1 Time Capsule 7 - "adopt" previous crashplan backup Somewhat stable at first under 10.8, worse under 10.8.1, better under 10.8.2 then unusable under 10.8.3. I'm now at 10.8.2 (using the combo update) and I'm sort of nervous about trying 10.8.3 again. If I do decide to go to 10.8.3, I'll use a downloaded combo update. I have had about a dozen Macs. I only ever did a wipe and install once when my daughter messed up her Mac mini badly by creating dozens of copies of applications in an effort to get around parental controls. I've seen people talking a lot of smack on MR about why Apple should have stopped releasing OS's after Snow Leopard. While I understand their frustration, I like the new features. I like iCloud. I like photostream. I really like shared photostreams. I like having a separate memos app instead of having my memos buried down inside mail.app. So if I fully trusted Apple right about now, I'd already be back on 10.8.3. As it is, I was dragged back up to 10.8.2 from 10.8 because my freshly updated iPhoto would no longer launch under 10.8. What I don't like is the windows-like experience I have been having where I have to spend so much of my valuable time tinkering with OSX to keep it running smoothly.
