Dual Core 2.3 - almost silent

After a 747-like PCI-X machine I'm beginning to wonder if my new Dual core 2.3 fans are broken. I don't think they were even roused during QT Pro encodes of DV->H.264.
Certainly not complaining but it's had me reaching around the back to make sure there's something flowing out of the vents! These are very quiet machines.

I've been doing some research on noise, and wonderind whether the dual2.3 might be too much. Thanks for your post. I'm off to the Apple online store!

AMD dual core 64 X2 and Opteron 1**; what motherboard.

Hi to everybody, my name is Mauro and I am Italian. I have had for many years a lot of mobos MSI that are shown always reliable and with really excellent utility. An example the LiveUpdate that unlike utility of other brand is very comfortable and reliable. Currently I have a system AMD 64 X2 3800+ stepE4 with Asus A8N SLI Premium and memory RAM G.Skill PC4000 (chip Samsung UCCC) F1-4000USU2-2GBHZ PC4000. I have many problems of stability and I would want to return to the brand MSI. I use the PC as Workstation I am not interested to the SLI and I would want soon to pass to the CPU Opteron 1 * * dual core. The customer care G.Skill has reported that the brands of reference for the development of the forms are the MSI and few others. You would know me to suggest a complete mainboard in the endowments, silent and compatible with the CPU from me you quote. How VGA I have both chip ATI X700 Silent Pipes 256Mb or NVIDIA 6600 always silent pipes 256Mb. I am not interested to overclock. I am observing with attention the RD480Neo2 and other mobo with chipset NForce Ultra K8N Neo4 Platinum. Thanks for your share and suggestions.
Mauro

Skippy, that's changing fast. Probably most major manufacturers are now explicitly supporting the Opteron.
Even MSI is getting there: K8N Diamond Plus
Hi,
To a careful study I have discovered that perhaps my Asus A8NSLIPremium has a problem that Asus is resolving. However I have asked to one friend of mine to make a will the MSI K8N Diamond Plus; in Germany it is already available some exemplary. The fact that the development has been made really with the Ram DDR that I have purchased (the G.Skill PC4000) it is a very important factor for the stability of a system. You introduces then with a good section of feeding to 4 phases it is very important. Certainly I am not interested to the characteristics of overclock but a Ferrari is not purchased only for racing. I have not told you that in so many years I have almost always had 2 brands that have always guaranteed me reliability: Abit and MSI. Objectively now that have tried also a lot of Asuses (5) I are not fully satisfied. For instance the Utility: LiveUpdate2 gave me reliability in the update of the bios (operation that finishes in DOS); the utility AsusUpdate because of a bug in the summer '05 are cost me 3 MB (update that departs in auto and it finishes in Windows). Resulted not could remain without MB I have had to purchase other identical MB. And treating itself of corruption of bios no guarantee. I have also discarded Tyan because it accepts only certified RAM DDR and their support it doesn't guarantee the operation with my DDR G.SKILL. Now that are in game I don't sell certain the DDR!

NX7600GT Diamond Plus and fan speed with Dual Core Center

I just got a NX 7600GT Diamond Plus for my HTPC. I noted that Riva Tuner and other utilities are not able to control the fan speed of the video card. The only way one can control the fan speed is via Dual Core Center and 3D Core Cell. The problem is that the default setting for fan speed on Dual Core Center is too high and clearly audible. How can I get Dual Core Center to start with user defined presets during windows start-up/boot-up ?
What I want to do is to put the fan into 'SILENT' mode automatically during Dual Core Center start-up. Any ideas / suggestions ?

Quote from: BOSSKILLER on 17-January-07, 00:44:11
well no need to edit manually, MSI provided everythink in easy way from core center.
select advanced mode, create your custom profile pickup your desired settings,(setup maximum FAN RPM via buttons) and save it to custom profile.
suggest you to read help section from program.
So the custom profile is automatically loaded every time DualCoreCenter starts up ? Maybe there is something wrong with my install of DCC, I cannot get it to load custom profiles automatically upon startup. I can save the changes to say "User Profile 1" but the profile active on startup always is the "default" profile ...

13'' dual-core with 16gb ram vs 15'' quad-core 8gb ram -- ram vs cores?

Hello. I am at a point between choosing a 13'' dual-core i5 with 16gb ram vs the 15'' quad-core with 8gb ram - both retinas.
I will be using photoshop and illustrator while uploading/downloading large files constantly. After much headscratching I almost decided on the 13'' i5 because from my experience, RAM limitations is where I usually run into problems, and don't see the extra price of i7 worth it when it is still a dual-core. For the same price I can get a 15'' quad, but will be stuck with 8gb ram.
I don't care about the screen size, I have good eyes and the weigth trade-off makes this a non-issue.
I'm thinking about down the road, as either of these I'm sure will be fine solutions. I'm just wondering where does the edge really come in this case? Ram or processor / cores?
Thanks.

Thanks for your reply tjk, of course with 16gb on the 15'' for $200 more I'd have easier time, but in this case I am comparing a refurbished - the lowest 15'' 16gb I could find would cost $500 more, I just can't do it.
I should make clear that this particular comparison between 13''w/16 and 15''w/8, they are the same price (the 13 being new) - which is why I'm stuck.
To rephrase - for the same price - which will I regret less in 4 years?
As a side note, I can't believe I'm even thinking about paying this much money for something that is not upgradeable, but that's another discussion entirely.

Macbook pro, dual core or quad core?

Hey guys Im getting an early college present and was wondering which Macbook I should look at. This will be my one and only computer while im in college. No photo editing or anything like that, maybe some video editing but it will be almost none. Will be used to surf the web and write documents. My question is should i get the dual core or quad core processor? Will it really matter for what i want it for? One thing I absolutely hate is lag! So the faster of the two the better.

tony477g wrote:
So if I went with the quadcore because you guys say it is faster than the 2.9 ghz dualcore. Would the difference be noticable between the 2.6 ghz and the 2.3 ghz? I noticed the 2.6 has 8 gb to the 4gb and 750gb to the 500 gb.
Well, actually, only one guy said the quad core would be faster, but it is not clear why they said that. You said you were only going to use it "to surf the web and write documents." Well, guess what. You don't need a quad-core for that. You don't need a dual-core for that. I've surfed the web and written documents on my old single-core iPhone. Those tasks are just not that demanding.
So unless there are more things you want to do that you haven't mentioned, there is just about no way it's worth paying for quad-core or a 2.6GHz processor if all you are going to do is surf the web and write documents.
The quad-core is going to speed up operations that specifically benefit from parallel processing, like intensive editing of photo/audio/video, or bulk encoding of audio and video, or specific math apps, stuff like that. And most Mac users would not benefit from choosing the 2.6GHz over the 2.3GHz because the performance of so many common uses depends not only on the CPU speed, but actually on the overall balance of CPU, RAM, and disc. In other words, if you really have a legitimate application for 2.6GHz it usually means you must also install a great deal more RAM and also an SSD to avoid creating a bottleneck that holds back the CPU. But then you would have a machine that is massively overpowered and overpriced for surfing the web and writing documents.
You could surf the web and write documents quite effectively on the least expensive MacBook that Apple sells. But since you do want to keep it throughout all of college, it is a good idea to buy something higher than the bottom of the line. For a Mac for very basic uses that should last four years, I would suggest:
13-inch MacBook Air with 256GB SSD storage and 8GB RAM
13-inch MacBook Pro with 500GB HD storage and 8GB RAM
13-inch MacBook Pro with Retina Display with 256GB SSD storage and 8GB RAM
(You didn't mention what your budget is)
I suggested 13-inch because it's more portable than the 15-inch but more comfortable for 4 years than an 11-inch. I chose storage sizes that would be appropriate since you said you would do some video. And I chose 8GB RAM because 4GB may not be enough for 4 years, and also because insufficient RAM is often a bigger cause of lag than CPU or disk speed.
If you have a limited amount of money, from this point on you'll need to justify why you would want a bigger screen, a faster CPU, or more cores given the two tasks you said you'd be doing most of the time. Because again, if you didn't actually need a Mac, you could write documents and surf the web on an iPad with the Logitech Ultrathin Keyboard Cover and be done for $600.

Is it worth recompiling for dual core?

I've just bought a new pc with dual core. Is it worth building none/some/all apps from source to take advantage of the second processor?
My guess is only some apps will benefit from having two processors, things like multimedia, can anyone confirm?

In answer to your first question, programs that support SMP (symmetric multiprocessing--the use of multiple cores/CPUs) should not need to be recompiled with a different ./configure flag (e.g. /var/abs/extra/gimp/PKGBUILD says that the GIMP is compiled with --enable-mp by default on Arch). However, modern CPUs (whether multi-core or not) support various optimizations (specific to each CPU) that may improve performance beyond Arch's default CFLAGS, which on i686 is CFLAGS="-march=i686 -mtune=generic -O2 -pipe". Using ABS, you can recompile [core], [extra], [community], and [testing] packages with your own CFLAGS, which you should probably copy from the wiki according to your specific CPU. Just note that you probably won't notice much of a difference in performance, if any, from Arch's default CFLAGS, so I don't recommend recompiling all your software from source. Let me refer you to CRUX or Gentoo if you want to follow that road. Of course, you should still set CPU-specific CFLAGS in your /etc/makepkg.conf because they apply to the AUR as well as ABS. While it's probably not worth recompiling all your software just to optimize a little bit further, you might as well optimize your AUR builds since you have to compile from source anyway.
In answer to your second question, yes you should use MAKEFLAGS="-j3". I've never had a program fail to compile because of make -j3, and it almost doubles the speed of compilation. Definitely use it. Actually, according to this, MAKEFLAGS="-j2" might be slightly faster, but I've always followed the convention of adding 1 to the number of processors or cores.

My 2010 15 in. 2.66 Ghz i7 dual core macbook pro randomly shuts off and reboots

I am a student at a college, and I recently bought a used MacBook Pro from the computer store which is part of a 4 year turnaround program when Faculty get new machines. It is a 2010 15 in. 2.66 GHz i7 dual core MacBook Pro, and I have had it for almost 1 week. After I got it, I installed Office 365 and Microsoft Document Connection. Almost immediately after doing this, and when I opened a Office application, it shut down. So I thought that installing Office 365 was somehow causing the computer to shut down. But over the past week, I've had maybe 3 more random shut downs including when all Office applications were quit and thus inactive. They were pretty rare, so I actually thought it wasn't such a problem because they didn't interrupt my work too badly. The screen suddenly goes black with no warning, and then immediately without me doing anything the computer reboots to grey screen, apple logo with languages / licensing stuff, tells me I shut down my computer due to a problem do I want to return to the screen I was on with all my stuff on it?, I say yes and it quickly goes to the desktop with everything I was working on pulled up.
So I didn't mind too much until last night, when it shut down twice within rapid succession of one another. Shut down, reboot, within seconds of me clicking on mail or whatever, boom, shuts down, reboots again. That was annoying. Then this morning, I wake up, open my computer to do work, BOOM shut down 1, open again, try to work, this time I'm using Safari when boom shuts down again time #2 within 1 minute of last shut down, then BOOM shuts down A THIRD TIME this time within 5 minutes of the last shut down. But still 3 SHUT DOWN/ REBOOTS in 10 minutes. Needless to say this is extremely annoying. Also, these last three times it has been on Battery power, but last night it was plugged in, so I don't think it's a battery issue. Also, my computer was fully charged (or almost) this morning, so it's not like it's on really low battery or anything like that.
I checked this thread: https://discussions.apple.com/thread/5044196?start=30&tstart=0, and it seems like I may be having kernel panics due to a defective NVIDIA graphics card. How do I tell what is causing these shut down cycles? How do I get it fixed? Also, needless to say, this MacBook is 4 years old, and I am not the original owner / purchaser, so I'm sure it's out of warranty. Does anyone know how much this will cost me at the Apple Store?

ggp057,
it could be due to the NVIDIA GPU defect in the 15-inch Mid 2010 models. It might also be due to faulty RAM. Do you know whether it has its factory-installed RAM, or if the RAM had been replaced? The GPU defect can be confirmed by making an appointment at your nearest Apple store to have them run their Video System Test on your MacBook Pro. Yes, it’s long out of warranty; the diagnostic test should be gratis, but if the defect is present, it typically costs a few hundred dollars to remedy (it involves a logic board replacement).
Did you also receive the two grey installation DVDs which originally came in the box with your MacBook Pro? Among other things, it has your model’s Apple Hardware Test. If you didn’t receive them, and the computer store is unable to provide them to you, then you can purchase a replacement pair from Apple. The Apple Hardware Test includes a RAM test, although it isn’t able to detect all possible RAM problems.

Older SP vs. Dual Core - Browser/Plugin Performance

Hi Gang
Have been down the block here many times. I'm very familiar with issues regarding the discontinued support of Flash Players and the frustration trying to keep your perfectly good running older G5's up to date.
Have question why I can't get the browsers in my older G5 SP 1.8 to work as satisfactorily with my two Dual Core G5's?
Details: I have 3 G5's #2 Dual Core 2.0's and #1 older SP 1.8. The Dual Core machines have #2 Browsers installed; TenFourFox ver 4, & Safari 4.1.3 with Flash Player ver 10.0 r45. Most videos in BOTH machines play just fine including UTube.
However my older 1.8 SP machine, (with browsers Safari 4.1.3, & TenFourFox ver 9), trying ALL archived versions of Flash DO NOT function properly. Each time I've used the Adobe uninstaller, then tried several/all archived players, always followed by 'Disk Permissions'. NONE will yield the same satisfactory results as with the Dual Core machines.
I'm wondering now if this situation could be related to the older 1.8 SP? Or perhaps have something to do with the Video Card in the SP machine? It's the only machine with an ATI, rather than Nvidia?
BTW, I also just tried a 'home-made altered' version of Flash, which was created by a skilled-creative person who's efforts are directed to us G5 users with NON-Intel machines. Anyway, it also failed ...
Any ideas?
Thanx
Mike

Mike-
Your video plays fairly well on Leopard in Safari (Flash 10.1) in my 2.0 GHz SP G4 w/Geforce 6800 GT.
With scaling on and full screen, the video is jerky. With scaling off, the video smooths and the video is enjoyable to watch.
HOWEVER, comparing the playback of the video on an Intel processor machine with much stronger CPU/GPU and Flash 11.1, the playback quality difference is marked; cinema-like as opposed to "web video"....
It's the only machine with an ATI, rather than Nvidia?
In your case, you have adequate GPU but inadequate CPU.
The 1.8 GHz machine wasn't good for more than 20-25 fps with HD at 480i.
128 MB VRAM and a mid grade GPU (9800 and better) are all that are needed in the graphics department.
One needs 30 fps and better to "see" smooth video.
If you were complaining about video with a FX 5200 or a Radeon 9600 I would say "get a better card".
In this case, No.
Video in OS X has ALWAYS been far more CPU bound than GPU bound... some comparisons to Windows put the diference at 5x more CPU.
BTW, Radeon drivers have, historically, almost always been better than Geforce drivers in OS X.
This is especially true in Tiger and Leopard.
I'm wondering now if this situation could be related to the older 1.8 SP?
Yes.
You are simply experiencing the limitations of the SP 1.8....... NO comparison AT ALL to either of your dual core machines, regardless of the graphics card.

Redundant Supervisors in a Dual-Core Catalyst 6500 network

Read the PDF doc called:
Designing a Campus Network for High Availability.
http://www.cisco.com/application/pdf/en/us/guest/netsol/ns432/c649/cdccont_0900aecd801a8a2d.pdf
It essentially recommends that dual supervisors only be used in SPOF points - not in dual-distribution or dual-core switches.
The rationale is that a layer three routing protocol convergence (EIGRP for instance) only takes 60-200ms, but a supervisor failover using NSF and SSO takes up to 3 seconds.
In practice, I almost always see dual supervisors recommended in the core (and that's what I've recommended as well).
I can see keeping dual supervisors in the core because the customer may place a higher value on redundant hardware capability than an up to three second convergence, but I'd like to hear other rationales why dual supervisors should be used in a redundant core given the definite speed advantage of routing protco convergence over convergence following NSF/SSO failover.
Thanks,

In a completely clean textbook design where the cores are mirrors of each other and only provide transit between distribuition layers, NO, dual sups are not needed and will only slow convergence as the document indicates.
However, in some live environments this is not always the case, where the textbook does not reflect reality. One core switch can have a configuration or connection that the other core cannot backup. As much as people try to keep their cores clean and symetrical, a fast growing and underfunded network can quickly get messy with one-offs and bandaids that get forgotten about a few months later. In situations like these, having dual sups in the core provides the peace of mind and assurance that 3 seconds can buy (if you can afford it).
Please rate this post.
Thanks,
Brad

G5 Dual Core with ATI X1900GT - upgrade to FCS2, Tiger or Leopard?

Hi everyone,
I am little confused what to do. So, maybe somebody can advise me what it would be the best.
Here is the situation:
I am still using my G5 Dual Core 2.0 with an ATI X1900GT card, 8.5GB RAM and Decklink SP (as below states). I intend to use it till the end of this year, and then to switch to the fastest at that moment Mac Pro. Now, I have 10.4.11 and FCS-1 with almost all filters from Noise Industries. Everything works perfect.
But I would like to upgrade to FCS-2, especially because of Motion3 new features. The questions are:
1. Stay with Tiger and do the upgrade to FCS-2? And after that how the Motion3 will work? With similar speed? Or better, maybe worse? (I am not afraid about Final Cut - it shouldn't be any problem, but what about Motion?)
2. Upgrade the system to Leopard, and then upgrade the FCS?
But what about the graphic card drivers? On the Ati/AMD web site there are still (from over a year) drivers for Tiger and not for Leopard. Without the proper drivers it could be a problem to install the FCS. Few months ago, when I was changing the startup disk for WD Raptor, I did the clean system installation and tried to install FCS-1. But I forgotten about installing the ATI drivers. When I tried to install, the FCS shows the info that this computer doesn't have the graphic card which support Quartz Extreme. Of course, after installing those drivers everything works OK.
So, how it could be with Leopard?
3. Will the all filters (I mean filter from Noise Industries) work fine in Motion and in FCP?
4. Will the old Motion project open correct in Motion3? I use the old project quite often.
+For those upgrades I can use another (cloned) startup disk to avoid the "dramatic" situation.+
I appreciate any help. Thanks in advance.
Marek.

Thanks for all replies.
It looks that it is not a bad idea to stay with 10.4.11, and upgrade only the FCS.
I will do this on my clone disk, and check if everything works fine.
But, is it possible to install Motion3 (from FCS2 upgrade disks) and leave the Motion2 on the same disk being installed? (I suppose no, but asking just in case)
I checked the specification of the Noise Industries - filters work fine in both system Tiger and Leopard (most of them I am using now, except of those filter which need FCP6 and Motion3), so I think I will stay with Tiger.
Peter, do you know what capabilities exactly I can loose staying with Tiger? Do you use those filters (or some of them)?
Marek.

HP Compaq CQ43-400TU Dual Core 2.2 (Second Gen) Processor Upgrade

I have HP Compaq CQ43-400TU Dual Core 2.2 (Second Gen) Laptop.
I want upgrade it Core i3 or Dual Core HT and VT Support Modles
if it possible
please give me list of supported processors

Here is the manual with a list of possible processors:
Manual
The B960 is the same socket as a 2d gen Core i-3 so it might work.
The only issue is that, many times, the motherboards used with the low-end processors have been defeatured and do not support all of the possible functions of the higher end processors. It is almost impossible to know 100% in advance whether a specific processor will work 100% in such a situation. I notice that the system board options list different boards for the i-series and Pentium systems which is usually a dead giveaway. The i-series might boot and run but not all features will work, more than likely.

Powermac G5 Dual Core 2.0 GHZ or Macbook Pro Dual Core 2.0 GHZ

I have a Macbook Pro Dual Core 2.0 GHZ that currently has 1 GB of RAM in it. For the most part it runs fine, but I do come into problems with it sometimes while I'm doing video editing which is my main usage for my computer. I currently run Final Cut Studio 2. Would it be worth it to sell this computer and get a Powermac G5 Dual Core 2.0 GHZ or 2.3 GHZ and upgrade the RAM to 8 GB to help my video editing run smoother? The reason why I am considering this is because I would like a computer that would work better with my video editing at a cost that I can afford. I also would like to have a firewire 800 port for my external hard drives. I rarely use my internal hard drive, so that is no factor in my decision. Currently I cannot afford a new Mac Pro, but will be buying one in about a year. I'm just trying to decide if this would be a good switch for right now. Thanks for your help.

Although I don't own a Mac Pro, rumor has it that they run video chores significantly more efficiently than do the last generation G5's. I bought my 2.3 GHz, w/the 7800 card, for $600, last November on eBay. The case wasn't cosmetically perfect (a rather nasty looking crimp on the front handle) but it has performed well running my video (EyeTV and recording) and academic (I teach math & Mathematica) needs. I picked-up extra memory (it now has 6 Gigs) pretty cheap (around $75, IIRC), from Kingston. I also took the advice of many here and got a WD 640GB HD that made a significant difference in both boot-time and opening applications. However, if you're going to get a new Mac Pro in a year, it's almost like throwing money away - the G5 will probably have its' depreciation rate decrease once the software vendors no longer continue supporting pre-Intel machines. That being said, my G5 is more than sufficient handling my present version of Mathematica - I don't think that paying $3000, or whatever it takes to get a new Mac Pro, would balance the marginal increase of utility I would get using Mathematica. If I were a video guru, I might feel differently. I thought I could give you a definitive yes, buy the G5, because I really love mine. Unless something happens, I plan on having it for at least a few years. At about $250/year, if one figures that I'll have owned it for a total of 3 years, that's less than 70¢/day. But I also value the opinions of many of the posters who have commented on the new machine's speed, compared to the 2.5 GHz Quad, say.

Dual 2GHz or Dual Core?

Looking in to getting a refurbed G5 tower. I was wondering if anyone knew of any drastic differences between a Dual 2GHz Powermac G5 and the new Dual Core 2GHz model. Like different PCI slots or something. Also, would there be any performance gain between the two 2GHz processors and the Dual core 2GHz?
And yet another question: Would I need an adapter to hook up an older ADC Studio Display (LCD)?
iMac G5 17" 2GHz | iBook G4 14" 933MHz | eMac 700MHz Mac OS X (10.4.4)

I would same there is a BIG difference
Atleast performance wise i have seen a 10% increase
compared to the dual model.
I would say that the 2x1MB L2 cache is a good thing -
Old model had 2x512kb
Also - The DDR2 seems a nice addition and perhaps
most important is the PCI-E bus.
Also the new machine is way more silent than old Dual
machine.
I notice the same with mine. This unit is super quiet compared to the 3 previous PM G5s I owned. The CPU fans run at a constant 600RPMs and never rev -- no matter what I'm doing. Also, this unit multi-tasks much better. I would go with the newest model.

TS1545 I have downloaded 10.5.8 combo several times and cannot get it to install because the disc won't mount or the installation gets hung up after restart. My current os is 10.5.1, and I am trying to upgrade to snow leopard. This is on a dual core macbo

I have downloaded 10.5.8 combo several times and cannot get it to install because the disc won't mount or the installation gets hung up after restart. My current os is 10.5.1, and I am trying to upgrade to snow leopard. This is on a dual core macbook pro.

You don't need to update to Leopard 10.5.8 unless you want to keep Leopard. Upgrading to Snow Leopard requires that your purchase the retail install disk.
The following covers Leopard:
Some general advice on updating:
It is worth noting that it is an extreme rarity for updates to cause upsets to your system, as they have all been extensively beta-tested, but they may well reveal pre-existing ones, particularly those of which you may have been unaware. If you are actually aware of any glitches, make sure they are fixed before proceeding further.
So before you do anything else:
If you can, make a full backup first to an external hard disk. Ideally you should always have a bootable clone of your system that enables you to revert to the previous pre-update state.
Turn off sleep mode for both screen and hard disk.
Disconnect all peripherals except your keyboard and mouse.
1. Repair Permissions (in Disk Utility)
2. Verify the state of your hard disk using Disk Utility. If any faults are reported, restart from your install disk (holding down the C key), go to Disk Utility, and repair your startup disk. Restart again to get back to your startup disk.
At least you can now be reasonably certain that your system does not contain any obvious faults that might cause an update/upgrade to fail.
3. Download the correct version of the COMBO update from the Apple download site.
The Combo updater of Leopard 10.5.8 can be found here:
http://support.apple.com/downloads/Mac_OS_X_10_5_8_Combo_Update
If you prefer to download updates via Software Update in the Apple menu (which would ensure that the correct version for your Mac was being downloaded), it is not recommended to allow SU to install major (or even minor) updates automatically. Set Software Update to just download the updater without immediately installing it. There is always the possibility that the combined download and install (which can be a lengthy process) might be interrupted by a power outage or your cat walking across the keyboard, and an interrupted install will almost certainly cause havoc. Once it is downloaded, you can install at a time that suits you. You should make a backup copy of the updater on a CD in case you ever need a reinstall.
Full details about the 10.5.8 update here: http://support.apple.com/kb/HT3606
More information on using Software Updater here:
http://support.apple.com/kb/TA24901?viewlocale=en_US
Using the Combo updater ensures that all system files changed since the original 10.5.0 are included, and any that may have been missed out or subsequently damaged will be repaired. The Delta updater, although a temptingly smaller download, only takes you from the previous version to the new one, i.e. for example from 10.5.7 to 10.5.8. Software Update will generally download the Delta updater only. The preferable Combo updater needs to be downloaded from Apple's download site.
Now proceed as follows:
4. Close all applications and turn off energy saving and screensaver.
5. Unplug all peripherals except your keyboard and mouse.
6. Install the update/upgrade. Do not under any circumstances interrupt this procedure. Do not do anything else on your computer while it is installing. Be patient.
7. When it ask for a restart to complete the installation, click restart. This can take longer than normal, there are probably thousands of files to overwrite and place in the correct location. Do nothing while this is going on.
8. Once your Mac is awake, repair permissions again, and you should be good to go!
If your Mac seems slightly sluggish or ‘different’, perform a second restart. It can’t hurt and is sometimes efficacious! In fact a second restart can be recommended.
9. Open a few of your most used applications and check that all is OK. In this connection please remember that not all manufacturers of third party applications and plug-ins, add-ons, haxies etc, will have had time to do any necessary rewrites to their software to make them compliant with the latest version of your operating system. Give them a week or two while you regularly check their websites for updates.
N.B. Do not attempt to install two different updates at the same time as each may have different routines and requirements. Follow the above recommendations for each update in turn.
Lastly, Apple's own article on the subject of Software Update may also be useful reading:

[b]If you are updating Safari (or just have):[/b]
Input Managers from third parties can do as much harm as good. They use a security loophole to reach right into your applications' code and change that code as the application starts up. If you have installed an OS update and Safari is crashing, the very [i]first[/i] thing to do is clear out your InputManagers folders (both in your own Library and in the top-level /Library), log out and log back in, and try again.
So, disable all third party add-ons before updating Safari, as they may not have been updated yet for the new version. Add them back one by one. If something goes awry, remove it again and check on the software manufacturer's website for news of an update to match your version of Safari.
Most errors reported here after an update are due to an unrepaired or undetected inherent fault in the system, and/or a third party add-on.

To reiterate, Input Managers reach right into an application and alter its code. This puts the behavior of the affected application outside the control and responsibility of its developers: a recipe for problems. That's not to say that issues absolutely will ensue as a result of Input Managers, but you, as a user, must decide. If the functionality of a specific Input Manager or set thereof is really important to you, you may well choose to assume the associated risk.
Again, the advice is to remove all Input Managers from the following directories:
/Library/InputManagers
~/Library/InputManagers
especially prior to system updates (they can always be added back one-by-one later).

Core 2 Duo vs Dual Core i5

I'm looking to replace my 2008 MacBook Pro (2.4 ghz Core 2 Duo) with a the new Mac Mini i5 Dual Core. I'm trying to decide if this is an upgrade in performance. I already use an external monitor with bluetooth keyboard and trackpad. I don't do much fancy but I like to increase my performance every couple years. I have almost never used the MBP as a portable unit. Pretty much stays on my desk.
I can't find any definitive info I could understand to see if this is worth the change.
Thanking everyone in advance,
Paul

this is interesting. https://discussions.apple.com/thread/3136777?start=0&tstart=0
points to this guy - the Echo Express: http://cl.ly/450a0n3f031S42052q3a
that might change the game. make me just stick with my MBP for a bit more to see what pans out.

Dual Core 2.3 - almost silent
