You might want to look into enabling TRIM. It's kind of annoying now with Yosemite. But seems like it's worth it for these drives. See here. Also - if you don't mind doing me a little favor: Once you're up and running, run a SMART tool like DriveDx and LMK if you have a non-zero value for 199 - UDMA CRC Error Count. I'm going a little crazy here with my 840 Evo in my MBP. That # keeps increasing, slowly but surely. It turns out I had bad RAM - which explains the weird behavior I was seeing (OS updates failing checksum, etc) that led me to notice this. But now I have all-new RAM, passed AHT, and the # is still going up! Running full memtest86 now just in case my new RAM is bad or I have some RAM controller issue. Just curious if you see 0 on yours.

Since the CPU is removable in the latest iMacs, whats the fastest CPU people have reported working in one?

It's been done, but I think the 12 core BTO option is the best possible processor on socket 2011. Though you'd save like $500 if you bought your own processor vs. having Apple BTO it, at the risk of loving something up during install.

Is the new MP 12 core option still faster than the last gen MP with the highest supported user upgraded CPU? I think the last gen MP 5.1s could run 2x6 core CPUs.

Perhaps it's too late, but try to make sure you pick up one of these: http://www.amazon.com/gp/product/B00UN550AC/ You really don't want the SSD to be swinging inside the case footloose and fancy free... If not the bracket, then some other way of securing the drive.

Done. I'm pissed off I didn't do this sooner. It was so loving easy. The hardest parts were getting the glass off, keeping it and the display clean, and fighting the magnets. Everything else was easy as poo poo. Here's how I dealt with the lack of correct bracket:

But booting from mechanical HDDs makes UI/UX so slow.

Because the CRC check is done in the SATA host controller, before anything has been written to RAM, it's not likely to be triggered by bad RAM. You probably had two problems, now you have one.

Oh yeah, definitely did. my boot time went from 5ish minutes (a lot of stuff runs on startup for me) to near on 30 seconds ready to rock. windows open too quick for me to close them now. No disk noise is great too. I did hit a snag - internet recovery wanted to re-install Lion, not Yosemite. I planned on doing a clean install, grabbing all my poo poo out of time machine and reinstalling just the bare essentials. Oh well, I will just restore from time machine. my time machine backup was too large for the disk due to 35GB of my 499GB going to the internet recovery. So I went to do the Lion recovery, figuring Lion>yosemite is as clean as it was gonna get. that was gonna take 4 hours. So I said gently caress it and pulled it apart again, put the old drive back in, wiped a 320GB FCPx file off the disk, did another Time machine backup and downloaded Yosemite installer. Stuck that on a USB drive, Shut down, re-installed the SSD, booted from USB (a few times, it failed a few times to the "no" symbol) and then eventually it booted to Yosemite install, and I restored from my TM backup. Once back up and running I went into time machine and grabbed the FCPx file and stuck it on a USB drive. All in all it took a long time but I did it a really long way. None of it was really bad besides the Yosemite from USB not starting, and it then running from the Time Machine disk instead (which was just confusing.) Now I want an SSD on thunderbolt for my time machine backups. The biggest annoyance in all of this is that Apple invested way too much on Thunderbolt the moment it was ready. Its pretty apparent its not a consumer targeted interface given the pricing and USB3.0 was probably a much better solution to bring in (and in many cases it appears faster for consumer applications at least)

I have a late 2013 retina macbook pro and am just about to pull the trigger on a 4k monitor. Just been reading that this machine apparently can't drive 4k at 60Hz. Is this still the case? Also is running a desktop at 30hz at 4k really that bad?

Found this segment from 2012 really entertaining concerning Apple for enterprise and HFS/ZFS: http://5by5.tv/hypercritical/56 One of the interesting take aways I found is that Apple doesn't use its own hardware or software(entirely) for its enterprise needs. So with that in mind, why should anyone else try to use Apple hardware and software for their own enterprise needs. I'm sure thats obvious for a lot of people but it wasn't so clear for me until I came across this. Not that I was trying to start a small business with all Apple hardware.

kuskus posted:Quite true. Mercury Playback Engine in Premiere Pro CC 2014 renders & encodes with GPU / OpenCL. If I didn't have the dual D700s in the Mac Pro I couldn't get home at a reasonable time. The 5K iMac is probably cool for designer/photographer/ non-production GPU; if you're doing heavy editing work and producing 60+ rendered spots in a day in a handful of formats, you'll be pleased you have a current Mac Pro. Octane 3 realtime 3D renderer supports OpenCL as well, start using CineWare nested compositions in After Effects & dynamic linking that stuff to Premiere Pro and you'll never _not_ hit the GPU. Turbulence FD supports OpenCL. It's a happy time to have a multi-GPU Mac. I thought Mercury was only really for mpeg4/h264 source material and it doesn't really help for DNxHD and ProRes.

Nope, it renders realtime effects in the timeline too. AME also uses the GPU. FCPX also uses the GPU in pretty much the same way, though I think Compressor is still CPU only.

I have used setups with a worse refresh than that using a horrific xp based thin client / server set up so I think I could cope, but it would be nice to hear if anyone has first hand experience of it. Boiled Water posted:I thought this was a limitation only under hdmi. I may be wrong. Nah, apparently it's to do with the processing capabilities of the actual machine, the clock speed of the graphics processor is not enough to throughput all those pixels at 60hz - although I have heard it's possible using windows via bootcamp...

I hope this is the right place to ask - i'm looking for a wireless remote/presentation device to use during Keynote presentations. I have a new MBP and was bummed to learn the official Apple remotes don't work with them. Don't really have a price range, just want one that works well. Any good ones out there? Thanks!

It might just be statistics, but it seems like the count is going up even faster than before (+20-30 in the last 30min).  I guess I could try to exchange the drive at MicroCenter... though the count did not go up when in my desktop. Major bummer if the SATA controller is failing. I guess I could try an optibay? I really want to use this computer for some performances, the first of which is a week from tomorrow. But it needs to be reliable... edit: hmm, I wonder if the connector for the optical drive is the same, i.e. maybe I can try to use the other SATA port before buying an optibay to confirm it works edit2: drat, cable is different. sata part is the same but not power

So following my iFixit RAM upgrade and battery replacement I did on my 2011 Macbook Pro a few months back, after a good four years the MagSafe power chord gave out. Despite all my sticky taping skills, the wires became so frayed that when I could get it to charge it would start smoking. As a rule of thumb it's generally a good idea to replace electronics when they start catching fire.  So I utilised some birthday gift vouchers and purchased a new one.
