OS X :: Difference Between 32-bit And 64-bit Kernel
Sep 8, 2009
So after reading a hundred million (maybe two or three less) messages on this topic, only confusion remains in my head. So here is a simple question for Mac experts:
I have an Early 2008 MBP (penryn, model MBP 4.1) which I think is capable of rebooting in 64 bit kernel mode. I have 4 Gb RAM memory and a 2.4 GHz C2D processor.
WOULD I SEE ANY DIFFERENCE AT ALL IN MY COMPUTER BETWEEN 32-BIT AND 64-BIT KERNEL?
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.
I am one of the many folks who use a PC and have been considering a Mac. I have read many posts on the subject of Macs vs PCs, that the Mac OS is more stable, doesn't get infected with viruses or spyware (I would assume virus/spyware writers go for the biggest target, Windows), and is ''easier'' to use.
Can someone please explain in plain english how a Mac is easier to use? I assume there are similarities like the use of file architecture and ''windows'', but why is Mac's way of running say Photoshop Elements better? Why, specifically, is the Mac OS better than Windows if you take out the virus/spyware issue? BTW, maybe I'm lucky, but in the 3 months I've been running XP, I haven't had a single crash, blue screen, or virus. Of course I'm knocking on wood!
I have a 12.1" ibook G4 [A1054] with a broken 2.5" IDE hard drive. I have an old IDE hard drive that was in a Gateway laptop. Is there any reason that I would not be able to install this drive in the ibook? Is there anything fundamentally different between hard drives in macs and hard drives in windows based machines?
The hard drive that was in the ibook is a 30GB and the Gateway one is a 60GB. I'm not sure if that would matter either.
If compatibility is not an issue, am I going to have any problems formatting the old Gateway HD or installing software on it?
Also, can anyone recommend a site that would be a good place to buy a 2.5" IDE hard drive in case I want to use a different one?
I'm looking to finally upgrade my Mac Pro to use an SSD as a boot drive, and I've been eyeing the OCZ Vertex 2 drives as a result of the beloved Sandforce controller. My question is, the only OCZ drives I've been able to find at the price point I want in my area are the Vertex 2 3.5 120 gig editions.

Is there any reason NOT to get this over the 2.5 version? I'm not planning on putting it in the optical bay as both are in use, and would just go in a regular hard drive bay. It's unfortunate that I wont one day be able to use it in my Macbook Pro should I ever upgrade however, beyond this am I suffering any penalty by going with the larger size?
I just received a logic board replacement for my iMac G5. I noticed a difference in the "Processor Name" in the "About this Mac". My old logic board was labeled: CPU Type: PowerPC G5 (3.1) The new replacement logic board is labeled: Processor Name: PowerPC G5 (3.0) What's the difference between the 3.1 and the 3.0 CPU Type or Processor Name? Did they replace my logic board with an older version? I am in China where they can put anything in anything - you never know!
Is there a simple way (i.e. 100% free, including using the Terminal) to determine which files in one folder are NOT in another, disregarding any extensions the files in each folder have?
One way I thought I could approach this, using the Terminal:
Code:
ls /path/to/first/folder > folder1.txt
ls /path/to/second/folder > folder2.txt
diff folder1.txt folder2.txt
Only problem is that this does NOT ignore extensions, so all the lines in both text files will be reported as different. This is NOT what I want.
I have seen that along with old mac mini "slot-loading Combo drive" was there. But with new mac mini "8x SuperDrive with dual-layer support" was there.
Can some body tell me what's the difference between above two?
There is a big difference I would notice by adding more RAM to my machine. I use Photoshop, FCP, VMware (windows 7 and XP) and all the basic apps (itunes firefox etc). Haven't done much gaming but want to now that I have my MP. Would I notice a difference by adding 2 or 4 more GB in my 2 empty slots?
I know there's a thread about how the new Expos頳ucks and all, but I wanna find out roughly how many people are actually annoyed by Snow Leopard's version of Expos鮍
Im in the market for a new mac mini and I was wondering if there was a significant speed difference between the 2.53 and 2.66 ghz versions. Also, I want to buy the model that has 4 gb of ram , 320 gb hard drive and I was wondering if this model came with a mini dvi to dvi cable included in the box? Or do i have to buy a minidisplay port to dvi cable.
I'm kinda' new to the whole audio recording process and I'm leaning more towards the 13' MBP bc the only difference between the 15' and the 13' is an optical in line. So, what does the optical line in do? And is it worth the extra $200 because i do not think 2' of monitor space is?
I'm looking at second hand 2009 quad mac pros. I'm not sure if 2.66 has a massive disadvantage over the 2.93. The thing is, I'm buying this for quite a long run (I work with audio/ Logic pro). I'm thinking that the 2.93 will be more future proof? Does anyone have any experience with the two?
I have used mac for some years now, and know the OS well, but there is something that always has confused me: There are three different libraries in OS X. the first is: Macintosh HD>Library - the second: Macintosh HD>User>Library - and i recently noticed a third: Macintosh HD>System>Library. The reason this annoys me is because, as everyone know, there's often programs asking you to delete files from the library etc. I know i could just search for the right directory but still... kind of annoying, and a bit confusing at times. So why do Mac OS X have three different libraries and what are the difference between them?
more USB 2.0 ports for my Mac Pro (early 2008). Which one should I get? at's the difference between PCI and PCI Express? I had added a USB PCI card in my G4
I am 99% going for the MBA. Now the question is HDD or SSD?!I have read all comments about speed difference but I would like to know the difference in heat between the two. Really dislikes heat in a laptop and hence if there is a difference between the two
I'm looking to modify the cal command that I've seen used for calendars in GeekTool to create a horizontal calendar.
I don't care about days of the week so much, I just think it would be interesting to have all of the days of the week listed out in order at the bottom of my screen, with the current one marked.
So, I need two things:
I need to strip out of the cal command the days of the week at the top (or repeat them the appropriate number of times, but I imagine that will be far more difficult) and the line breaks at the end of each week. This is the most important part.
Secondly, I'd like to find a way to add bars (like this: |) on either side of the current date without replacing the numbers as most of the calendars I've seen have done it.
Here's the code I've seen:
Code: cal | sed "s/^/ /;s/$/ /;s/ $(date +%e) / $(date +%e | sed 's/././g') /"
If I can just modify that to get what I want, that's fine, if I have to use something completely different, that's fine. I just would love to have a horizontal calendar.
im looking into buying a macbook air and was just wondering if their is much difference in performance between the 2 cpu options when used with the sata hard drive?also any advice to consider before buying a rev 2 macbook air would be great
When I connect my MacBook to my iMac to transfer files over (using target disk mode), a sparsebundle of my macbook files shows up as a mounted disk image, along with the yellow external hard drive icon on my desktop. The yellow icon says I have about 80GB total, but the mounted disk image (white) says I have 120GB total on it. Does that mean I have more space than I originally thought? (I thought it had 80GB on it)
Looking at Seagate site, even newegg, the hard drives for mac are incredibly more expensive. I doubt the interface is different, so the only other option is how it is formatted.
If the drive is formatted differently, at an extra cost, I am curious if OSX is capable of formatting externals on its own? Can I buy a standard drive and format it natively in OSX?
I only ask, because after coming from Home Premium, several hardware utilities are non-existent.
A while ago we got more ram, and I was looking at it in about this mac and I noticed a difference to the ram that came with the Mac. Is there anything wrong with that?
What are the differences between the Previous-gen 15" 2.4gz vs the 15" 2.66 version one? Specifically i mean the ports and the "real-world" speed of the processors.
