The "prompt replies for meaningful inquiries" phrase sounds like someone hit the thesaurus before hand, but otherwise it seems fine. To check just turn it on and make sure it boots in the 11 seconds or so it should take. Open a bunch of applications immediately and try using a couple of them simultaneously to make sure the RAM and SSD can handle the workload. Then restart the computer to again make sure the SSD is legit (should take ~15-20 seconds max to reboot).

A single 32-bit application (regardless of if you're running a 32- or 64-bit OS) can't access more than 2 gigs of RAM; if your system has >2 gigs free memory when idle, there is no reason to get more RAM fora a single 32-bit application, which currently includes all games in a meaningful sense.

I have a Mac Pro 1,1 with an AMD Radeon HD 4870 that I flashed a few years ago, but the RAM on the card has gone bad, so I need to buy a new one. I'm willing to buy another 4870 and flash it again, but I'm wondering if there might be something easier now? I got the 4870 because I do a lot of graphics work in After Effects but also use boot camp to play some games like Bioshock and Batman Arkham City. Is there a cheap, quality video card I can buy that I can throw in my machine that'll work the same or is my best bet still to get another PC 4870 and flash it?

That's not true either, unless you're on Windows. UNIX application could generally use up to 3GB on a 32 bit kernel (with 1GB as kernel address space), and 32 bit applications can use 4GB on a 64-bit kernel. In the case of OSX, it does transparent PAE for 64 bit since 10.5 (64 bit kernel wasn't the default until Lion), so again, 32 bit apps could use 4GB of memory. It's difficult to find documentation on how much kernel address space XNU needs. At about 64b for every 4k mapped in PAE, it's something like 32MB of memory to give you 32GB of addressable memory. In other words, this could not be more wrong, especially as it applies to OSX.

I'm pretty sure you can use anything from the Radeon 5xxx/6xxx series, as well as Geforce 6xx (and maybe 5xx) as long as you don't use Bootcamp, since there won't be any graphics at boot without EFI strings. If you need that, get some cheapo supported card and use that as your display device for booting. Edit: See here for more discussion.

The 2 GB limit you guys are thinking of might be something that applies to Windows or non-PAE systems or something that's not true of Mac OS X's x86. The entire system could definitely address more than 4 GB for a long while due to PAE. But for Mac OS X, especially now, 4 GB is the single-process 32-bit limit. It's in the opening paragraphs of the 64-bit transition document, for example. edit: vvv Ah, Windows people. Nevermind then. x-virge fucked around with this message at 20:22 on Sep 17, 2012 |

In which case it should just be 16GB, since he's already thinking about dropping >$2k for a rMBP, and the GPU is going to choke a long time before memory is important. The 4GB/LARGEADDRESS patcher for Windows is common enough if gamers are really convinced that the developer is a drooling retard who didn't bother to test whether or not addressing more memory would really help performance, but the guys with watercoolers in mom's basement can squeeze more oomph out of it.

So if I want to get a new laptop, I would need the MBP to keep the 15" screen. However the MBP is more expensive and has a lot of stuff I really don't need. On the other hand, the 13" MBA gives me the same resolution, a solid state drive, but I would have to buy separate peripherals for cd burning and for an audio in. Perhaps I should go for a refurb MBA that still has the audio-in switcher for the headphone jack?

How often do you really use the audio in? The new MBA is significantly faster than the refurbs. If you can, you should just get a $30 USB audio-in, and use it when necessary.

Yeah, I posted the Griffin iMic earlier and no one gave a poo poo, evidently these guys want to build a grass roots movement to get Apple to give the MBA a dedicated audio in instead of shelling out $25 for a device that lets you use any standard mike for USB audio-in. Edit: where the hell in the OP does it say not to buy a new MBP? I helped write the OP at one point, I don't see where it says don't buy a brand new MBA. Edit 2: OP needs to be updated 'cause Apple definitely went to USB 3.0. It's in all the 2012 models of the MBP and MBA. Binary Badger fucked around with this message at 21:06 on Sep 17, 2012 |

New guy is starting and wants a 13" Pro. I was going to order him a refurb base model and then add 2x4GB and a 256GB Samsung 830, but for about the same price and zero hassle there was an i7 8GB/128GB 13" Pro in the refurb store Apple is still using the 'old' SSD in the non-Retina Pro, right? I guess if it's as fast as the 2011 Air SSD it should be fine.

It's faster and has significantly better battery life. The OP isn't updated with the 2012 models, but even given that it's not, the 2011 Air wipes its rear end with the 2010 Air. In this case, you absolutely should be buying the newest model, albeit not from Apple themselves, necessarily. If you use it for recording mixes, you're probably going to want better audio quality than what the generic (probably ungrounded) input gave you anyway. If it's "not too often", get a USB audio device and deal with it.

I think it's better than you'll find most other places (that's the newest model), but you could get it for $100 less if you can live with a 128GB HD and additional storage on USB media of some kind.

These are new third-generation SATA solid-state drives, which are up to 4x faster than a traditional hard drive. Apple makes the same 4x claim on the Air's page - so hopefully there's the new, fast drive in this model. I guess I'll find out for sure in a few days when it shows up.

If the iMacs only gets a minor bump, I don't know if I'll be compelled to them any more. I'm just kind of weighing options while the time passes. I can get something that runs smooth as a photo editing machine for the next two years I'll be happy. I think I should just plan to sell my machine off every couple of years and buy something new. No sense in keeping a computer until it's too weak to do what you want to do and has lost almost all its value (like my 08 MBP).

I've got the 512GB model of retina MBP which I use plugged into a Thunderbolt display at home and I can't really tell the difference in performance between it and the top of the line iMac my Dad bought himself last year. The retina MBP is also more responsive when using an external display in clamshell mode than when mobile because the screen resolution is quite a bit less than the Retina display. The main downside to retina MBP + Thunderbolt is the price, but if you can afford it and you need mobile computing power it's probably your best bet.

If you intermix USB2 and USB3 devices into the same 2012 MBA, do your transfer speeds get capped at the max USB2 transfer rate? e.g. suppose I have a USB3 hard drive in one port, and a USB2 mouse in the other. Will this cause the drive transfer speeds to throttle? Sorry if this is a stupid question!

It's not a totally unreasonable question, there are some wire technologies out there that do drop to the lowest common denominator. Ethernet will drop everyone to the lowest common speed if you're not using switches, for example.
