All Macs in Apple Store having problems?
I've got a 2.6GHz, 512GB SSD, 16GB RAM Retina MBP on order to replace my aging early 2008 17" MBP. I'm extremely stoked about this upgrade, so you can imagine my disappointment when I started to hear mention of issues relating to UI lag!
I couldn't bare not seeing this Retina MBP in person any longer, and seeing first hand if these issues were truly a problem or not. So off I was to the Plano, TX Willow Bend Apple store during my lunch break.
As soon as I entered the store, I circled the table of RMBP's like a Moutain Lion stalking it's prey. My mouth was salivating. It truly is a sexy machine. Coming from a 17" MBP, the light weight and super slim form factor are like night and day! The build quality is top notch, the screen is absolutely gorgeous! If you have a chance to check one out, open Aperature and pan around on one of the super high resolution photos they've pre-loaded - simply stunning.
After drooling over the aesthetics, I figured it was time to get on with actually using this beast! I shut it down, and booted it up. Just as the reviews had been saying, about 17 seconds from after my finger was lifted from the power button to when the desktop appeared. Awesome! I was very, very, very pleasantly surprised to see that what others were saying about the 'scaled modes' was true - the display looks insanely great not only in retina mode (1440x900), but also in every single other display mode offered. That's kick-ass.
That's when I began to perform some of the tasks that have been discussed in this thread. I swiped from space to space. I put apps in and out of full screen mode. I invoked mission control. I dragged windows around. I added the "Applications" directory to the dock and after clicking on it, tried to scroll up and down through the list of apps. I loaded pages like apple.com and theverge.com in Safari doing a fair bit of scrolling(both full screen and partial screen modes). I performed all of these tests in every single resolution(or display mode as Apple is calling it now). I performed all of these tests with both automatic graphics switching on and off(yes I rebooted after making the change). I rebooted several times, I made sure no other apps were running. I made sure all of the system updates were installed. Unfortunately, there is some bad news. Fortunately there is also some good news.
The bad news - animations looked positively *horrible*. Stuttering, extremely low frame rates. Tearing. Windows not animating at all in some cases and just appearing in their new position rather than moving. My early 2008 MBP (1920x1200) ran circles around this thing when it came to animating general Mac OS X UI stuff(e.g. expose). The results were all exactly the same, no matter which combination of these modes I had the machine in. Some people have commented that it has something to do with the background apps that Apple is running on these machines in the stores, so I spent some time investigating that very thing. At one point I had Activity Monitor open, and I saw one of these store background services(I think the concierge service) spike and stay at 100% CPU usage for a while when I was going in and out of mission control. I killed both this service and the "Desktop Icons" app using Activity Monitor. Unfortunately, It didn't seem to make a difference, however, there might be other services/apps running in the background with more obscure names that are chewing up GPU cycles(but ostensibly not CPU)? I began taking some videos, all the while seriously, for the first time considering the possibility of cancelling my order. I took three videos before an Apple Store Employee told me I wasn't allowed to take 'photos' in the store - is this true? that's seriously lame. I was prepared to upload them so that others in this thread could see for themselves the problems I encountered. Worried yet? Don't worry, there is a light at the end of this tunnel...
The good news - I visited at least one model of each product line in the store. I wanted to see if any of the other machines suffered from the same symptoms. Guess what? They all did! I tried the same suite of tests on a: MacBook Air 11", MacBook Air 13", MacBook Pro 13", MacBook Pro 15"(Non-retina, fully loaded), iMac, and even a Mac Pro. Every single machine suffered from the exact same issues. I don't know exactly what is different about the machines in their stores as of late, but my god, it's bad. It's a *horrible* experience. I don't recall ever experiencing this while playing with the macs in the stores before. The upside to all of this is that it now makes complete sense to me as to why people who have actually purchased and received their RMBP are not experiencing these problems.
Long story long - I wouldn't worry about this. I think it's a non-issue. Apple retail execs should be worried though, as this is a horrible experience for potential buyers.
I can't wait until I receive my new RMBP. Apologies in advance for the long posting.
