just got me a brand new 2010 MacPro 2 x 2.4 Quad-Core with 12GB Ram and the ATI 5870. This is the first MacPro to system boot into the 64bit Kernel by default (ie, hold 3+2 on restart to boot into 32bit Kernel). One of the first things I did was run the Photoshop performance test, which FYI on my old G5 2.7 with 4GB Ram returned a time of 114 secs, and on the new Quad-Core in 64bit kernel returned a time of 14 secs, so as you can imagine I was pretty happy with the results.
Then the problems started...... when I was installing software I got the dreaded Kernel Panic, restart your machine screen. So I did, and it happened again on restart, so I did, and it happened again on restart, so I did.... you get the idea. So I put the system disk in and restarted, then reloaded OSX10.6.4 and everything seemed to be going fine, until I installed software again (different app from the first time), and I got the Kernel panic screen, then again on restart etc, so I booted into 32bit kernel and all is good. EXCEPT! - When running the Photoshop test in 32bit Kernel it returned a time of 17secs. Now, I know I am being picky here, but I do a lot of work in PSCS5, and by a lot I mean sometimes all day on large photographic images, so 3 secs is a big deal....
Yes you read that right. Your brand spanking new MBP will use a 32-bit kernel as default.
You can force 64-bit kernel but some of your hardware will not be working.
So all that marketing crap about the benefits of 64-bit etc are all B.S.
I don't want a million threads about how this will not effect the running of 64 bit apps, etc. because it will. Your 64-bit app will run but it will not be able to address more than 4Gb of RAM.
There are also many more advantages to having a 64-bit kernel.
It appears that for whatever reason, the kernel on my Mac is 32bit/i386, but the architecture is 64bit: Darwin system.local 11.3.0 Darwin Kernel Version 11.3.0: Thu Jan 12 18:48:32 PST 2012; root:xnu-1699.24.23~1/RELEASE_I386 i386
Though the kernel itself is a universal binary: mach_kernel: Mach-O universal binary with 2 architectures mach_kernel (for architecture x86_64): Mach-O 64-bit executable x86_64 mach_kernel (for architecture i386): Mach-O executable i386

I know this has been asked numerous times, but most of the answers I found were old and archived. I was wondering whether or not an update or a guide has been released which allows a successful boot into 64bit kernel? Â On a side note, I have verified my computer does have EFI64. However I know in the past that this stil didn't enable a 64bit boot.Â
Whether anybody got Snow Leo build 10A380 (WWDC'09) successfully running with 64-bit kernel? If 'yes' - please share your method. I've tried every approach that i know: "6+4" keys, arch=x86_64 flag specified for both nvram and com.apple.Boot.plist, lipo command against mach_kernel.
I currently have external storage devices by DataRobotics - 2 DroboPro and 1 DroboElite. I bought the new MacPro 2 months ago and have been having problems with the Drobo devices disconnecting constantly. After a lot of diagnostics including Apple replacing the logic board in my MacPro, it was identified that the issue was with the iSCSI initiator that DataRobotics uses. It is not 64bit kernal compatible and as a result, the drives disconnect randomly especially when moving data from one external drive to the other. I am forced to boot the MacPro in 32bit kernel mode for the drives to work properly. DataRobotics is not committing to fixing the 64bit kernel issue so I'm now looking to replace this technology.
I found some interesting technology by Netgear and was considering buying their product, however, I had the worst experience ever with dealing with pre-sales & technical support department, after dealing with 4 different individuals, I concluded that they have no clue about their own products, the staff is so junior, it's as if I called a completely different company when talking about their own product. I am therefore going to stay away from that company.
I know by default that Snow Leopard starts up in 32-bit kernel but anyone here boot into the 64-bit kernel? I think to do this you'd have to hold down 6 and 4 keys while booting.
By now almost all 3rd party apps are running 64-bit and all this time I've totally forgot about the 64-bit kernel!
I've just booted up to 64-bit kernel and all apps load instantaneously!
So, with Snow Leopard, there is a 32-bit kernel, and a 64-bit kernel. Correct?
As I understand it, it will boot into the 32-bit kernel by default, but if your hardware is supported, you can select the 64-bit kernel.
My question is - where is the list of supported hardware, and how do you select the 64-bit kernel?
My confusion comes from several posts and various articles which all say the first-gen aluminium iMac has a 32-bit EFI, and therefore can only boot into the 32-bit kernel. But I've just downloaded an app called Startup Mode Selector, which shows you your system config, and it says I have a 64-bit EFI.
How does StarCraft 2 perform on the current lineup of the iMac? I'm most interested in the 21.5" model, as I cannot afford the 27" version. Specifically, I'd like to know what resolution and settings the 4670 and 5670 models can handle...
I have been struggling with my Mac for weeks and weeks and before I finally decide to reinstall everything I wanted to turn to you experts for maybe the one hint that can resolve my problem: I have a 13 inch MBPro, mid 2010, basic version. Later I installed the WD Scorpio Blue 1 TB hard drive and copied the time machine backup. Shortly after, I recognized massive lags. I have quiet a few photos (3000 or so), 20gb of music and 40gb of films on this drive but only a few programs. Adium, Steam, Starcraft, MS Office, Skype, Growl and that is it I think. I use mobileme for synching, if that helps in any way.
Some examples: Sometimes youtube videos lag for a few seconds, even with HTML5, it takes 5 seconds to open a new tab in sapharie (again, only sometimes without any obvious rule)..................
It looks like it is less expensive to upgrade the memory to 8GB from Apple now. I need to decided whether to go for 4GB or upgrade to 8GB BTO. With the 8GB RAM, will there be noticeable gain in performance? I guess VMWare Fusion may run better. Not sure about other applications including the OS
Just bought this recently and installed Windows 7. The following screen shot under WEI Macbook Air 2010 13'' 1.86GHz 4GB RAM 256GB. The performance is quite amazing consider its 1.86GHz CPU, I bet 2.13GHz CPU would score bit higher.
Performance of the new MBP's as they take on the slew of new games being presented (VALVe has said they will release new games each Wednesday, so keep looking for your Css' and L4D's)

Counter Strike Source will not be here all that soon so don't get your hopes up, they are redeveloping it, to run on a new engine. No point in porting the old engine when they will just have to do it again. Link:.....
I have a 15" 2010 MBP. I got it well spec'd, with 7200 drive, 8 GB ram, best CPU... First thing I did was bootcamp. Went smoothly - did a 400 gb partition for Windows 7. The drivers all installed fine and Windows 7 does alright.
My Windows Experience scores: Processor: 6.9 RAM: 6.9 Graphic: 6.4 Gaming graphics: 6.4 Hard drive: 5.9
Things look good... But I am having trouble playing hidef content - VLC is choppy on a bunch of files that play smooth as silk when booted into Mac OS - and actually even play ok on my old Santa Rosa 15" MBP. Quicktime is also slow. I have always found VLC to be very solid. (actually use it on the Mac side for this test as well). I tried playing with the hardware acceleration toggle, and it does seem better with it disabled - anyone else having issues playing hidef media on the windows side of this MBP?
For the past two weeks or so I have been getting a lot of Kernel Panics. Most of them happen when I select Restart or Shutdown. There have also been cases of Final Cut Pro crashing regularly, but I think the Kernel Panics are far more important to diagnose. I have not changes any hardware for at least a year. The machine has 4.5gb of RAM and 40% of the system drive free. I have run Disk Utility to repir the disk as well as the permissions, all coming back with no errors. The only thing that I can think of that changed is that I purchased and ran Disk Warrior 4. It seemed to help tremendously with performance, however, it is the only thing that I can think of that has changed. I am also suffering from some performance loss as well. I get at least one Kernel Panic a day. I have no idea what the KP mean, but they all look similar.

I have looked over the postings closely but may have missed something. What is the current knowledge, now, in early September about Apple-installed SSDs and performance degradation over time? Early concern beginning with the release of MBP 2010 in April was the the lack of TRIM support in OSX. Has anyone at this point noticed or measured significant degradation of factory-installed SSDs? I am ready to purchase a MBP 2010 and I am considering a 256 GB SSD.
First I wanted to upgrade my new mac mini with a Momentus XT but now I'm thinking about getting a "real" ssd + a FW800 drive for storage to have the huge speed boost of the ssd drive. Does anybody have this combination in his mini? What I want to know: How is the performance like of the external drive connected to FW800? Is it comparable to a standard internal hard drive?
I just upgraded my hdd to a 500gb WD scorpio blue in my 2010 MBP 13". It seems to start and stop a lot more than the apple one (if that makes sense). and every now and then the computer seems to lag for 1-2 seconds when doing things like typing, scrolling, etc. I've tried searching and found other people have had similar problems with older MBPs and they talked about some EFI firmware or something. Does this apply to my MBP too? Or does anyone have any other suggestions of what I can do?
I needed to upgrade this unit in order to increase performance with VMWARE Fusion as I needed to use a few Windows 7 features and Applications... and although Mac OS is OK... I have to recognize that some features of Windows 7 are better and I need some only windows applications.
So I researched online the option of upgrading memory and HD. I read mixed opinions and experiences with non Apple Memory. But took the chance and during a recent trip to the US I purchased the Kingston upgrade kit... installed it... and so far no problems. I got a very noticeable increase in startup and working performance with Windows 7 and Fusion. Unfortunately I lost my notes regarding performance readings... sorry.
I was very intrigued with the Hybrid Seagate 500GB Momentus XT. Also read a lot of mixed experiences. I also picked up a unit during my trip to the US but waited to install it when I got back to Spain. I just installed it and made some simple timings to check the performance......................
I was told to run Vista 64bit for games, but I was wondering about this� Since many applications don�t even have a 64bit version out and I don�t think games are 64bit, will they all run under vista 64bit? I have a feeling this might be a dumb question, but I just wanted to make sure before I go out and buy Vista 64.
Also do you think windows 7 is better for games? Will it even run games that have not been written for it? Or would I just be better sticking with vista 64 until everyone has caught up and made their apps compatible with the new windows 7? I mean will antivirus programs, ripping apps, etc work under windows 7 without a hitch, or should I wait and just use vista64 for now?
I have an iPad 32GB WiFi and a MacBook Pro as well so I was trying very hard to justify myself in getting an 11" MBA but ending up talking myself out of it. The 13" MBP is perfect for my uses. It's already lightweight and portable as it is. After playing with the 11" in the Apple store, I was impressed on how light it was. This no doubt blows away any netbook or any notebook in it's weight class in terms of size and performance. However, the MBP's battery life, hard drive space, and processing power OUTWEIGHS the reasons of dumping my 13" MBP for the Air. Also, I have it hooked up to a 21.5 Inch HP monitor at home and it's good enough to use as a main computer at home, and light enough to take on the road.
If I needed to lookup something quickly in bed or around the house, that's where the iPad comes in. If I needed to send a quick e-mail, my HTC Evo is already great at doing that. If I didn't have a 13" MBP or even the iPad, I would have most likely went ahead and purchased the MBA. Just now at this point, spending another $1000+ or getting rid of my MBP doesn't make much sense... yet.
I've been lurking MacRumors ever since 'the wait for Arrandale' began and finally decided to sign up now so I could post this thread. I've been a Windows user for a long time now and I have a Win7 rig at home. However, I'll be going to uni later this year so I need a good portable notebook that's suitable for the common mailing 'n surfing, but also for doing some programming in Eclipse (Java) and PHP work etc. I still have my Win7 box at home for gaming and things that require larger screensize, but for the notebook... I feel really attracted to OSX with a MBP.
It will be my first Mac, but my desktop dualboots with OSX and I love it. So that's why I have decided that my school notebook will be a Mac. This is why I have been closely watching the rumors for the new MBPs and ofcourse I was pretty disappointed when I saw that the 13" model still had a C2D cpu... It's not that I need a beefed up CPU in my notebook (... I have a 3.6 GHz quad at home ), but it feels 'wrong' to buy a MBP 13": even the 2009 MacBook has a C2D, so what will the MB 2010 update bring? Is it really worth the extra money? Anyone with a similar situation?
I'm currently experiencing a problem running my Suitcase Fusion 4 with my iMac. When logging onto the web, all web pages shows upo with text as "A" within a block. To relieve the problem, I've been told to upgrade my software. However, I need to first verify one thing. Does OS X 10.7.4 run on 32 or 64bit?
I recently reformated my PC and put XP Professional 64bit on it, did all the updates that I possibly could. Installed/downloaded all my games, updates, patches. Customized windows with everything that I like. Installed my AVG 8.0 Pro antivirus, Just everything that I want with a PC.
is there a way to totaly save my entire windows install? Like if I were to upgrade from a 500gig to a 1 TB hard drive? I know some PC repair shops use a program to do this. I think it has the word "Ghost" in it? Is there another way also? I have an external 500 HD that I would save w/e I need to save on it to make it work.
I just read the seed notes for Snow leopard latest build and when reading what I can test 64 bit apps with seems pretty much any mac in -08 and -09 except (!) MBA and minis.
Any idea why?
I thought at least the MBA rev B would be 64-bit capable...?
My apologizies if this has been discussed but if so I have missed it.
Contrary to belief, Snow Leopard by default (except for Xserves) runs in 32-bit mode. Check for yourself.
Code: uname - a You should see something similar
Code: root:xnu-1456.1.25~1/RELEASE_I386 i386 I forced it to 64-bit on my '08 Mac Pro and things were slower! Spaces was very slow. Dashboard was quirky. I say avoid it.
I've got a mid-2007 C2D MBP with 64-bit EFI and obviously, 64-bit processors.
'6' and '4' on Snow Leopard won't boot into 64-bit mode. I don't need the 64-bit kernel at this point, but I'm mostly curious to see what drivers and apps breaks under a 64-bit kernel and the only way to find out is to try it.
There's a pretty nifty hack involving hex editing boot.efi that works for some suitable Macs:
[URL]
No mention of MBP, and my attempts at guessing offsets and values while hex editing didn't cause any booting issues but didn't result in 64-bit kernel loading, either. Anybody happen to know offset and value in boot.efi to mod for a MBP?
I know this is a real long shot type of question and I'm not expecting anybody to know. But if you do, would love to find out.
I have a 15'' unibody mbp with the 9600M, and the nvidia notebook driver installer always fails to recognize my graphics card and quits. Is there a way around this? I have tried modifying some INF files but it doesn't work.
How's it going everyone, I'm fairly new to Mac and I'm not very technical at all. I just purchased an i7 15" and I'm confused when it comes to 64bit vs 32bit. Does the computer automatically switch between the two or is there something you have to specifically do to run one or the other? For instance, I downloaded Handbrake last night, it asked if I wanted 64bit or 32bit? I have no clue? I bought a powerful machine, I want to make sure I utilize it.
