IMac 21.5 inch 3.6GHz dual core works virtually like a Quad?
I read on apple.com that the iMac 21.5 can be configured to have 3.6GHz processor which supports hyperthreading. Does this mean, this will have 4 virutual processors/cores?
This machine has 3.6GHz dual core processor so, 3.6 + 3.6 = 7.2. Does this mean it is only approximately about a core less compared to a Quad core machine (Mac Pro or iMac)?
I'm just trying to understand all this and choose a machine which is not an overkill. I have a 2 year old Macbook pro which is fast enough for audio work but I'm looking to do video editing with a new desktop that I want to buy soon.
It seems the best thing to do is wait for some more benchmarks. Barefeats has some good ones, unfortunately they don't yet have a 3.6GHz i5:

I Have bought The new MacBook Pro 13-inch:
2.9GHz dual-core Intel Core i7
Turbo Boost up to 3.6GHz
8GB 1600MHz memory
750GB 5400-rpm hard drive1
Intel HD Graphics
My Q: Can I upgrade my memory ram from 8GB to 16GB ?Sure. Make sure that you buy the RAM specified for your computer - 204-pin PC3-12800 (1600 MHz) DDR3 SO-DIMMs - and purchase from a reputable dealer such as Crucial, OWC, etc.
You can go to the Crucial website and use the System Scanner app to get the correct RAM for your unit.

RAM Update to 8 or even 16GB on MacBook Pro 13-inch 2.5GHz dual-core Intel Core i5 mid 2012?
Hey folks,
i heard and read rumours, that it is possible to update the ram of the MacBook Pro 13" (mid 2012/no retina) to a double 8GB RAM, making it 16GB.
Which would be great, right?
Apple says on the support website that all the MacBooks 13" are only able to hold two 4GB making it 8.
Currently I only have the standard two times two 4GB.
So i was wondering, since I found this Crucial PC3-12800 DDR3 1600MHz 8GB SODIMM on the Internet if that's a fit for the rumours.
It says on the site:
"Guaranteed compatible with:
MacBook Pro 13-inch 2.5GHz dual-core Intel Core i5 mid 2012
Now, has any one experience with this one?
Maybe this memory will plug both slots and that's why it says compatible?
you find the website here: http://www.macdimms.com/Crucial-PC3-12800-DDR3-1600MHz-8GB-SODIMM_p_123.html
appreciate the help.It won't plug both spots. To get 16 GB you will have to buy 2 sticks, one for each slot.
Apple only recommends and will suport 8 and recommends installing in pairs - so 2 slots of 4 GB each. You can always try the 2 slots of 8 and see if they will work. I would recommend ordering from crucial direct. They are one of the better memory companies around and have a website at crucial.com.
You shouldn't have any issues as the maximum non-Apple supported config is 16 GB.
Good luck. -

Hello there.
Doe's the reconfigured mac mini with the fourth generation 3.0 GHz Dual Core i7 with 3.5GHz Turbo Boost, with 1TB Fusion Drive, run at 7200rpm?
Thanks.Historically Apple have generally used 5400rpm hard disk drives and while the detailed information on the Apple store does not definitively say what speed hard disk the 1TB Fusion drive includes, it does make mention of testing conducted with a 5400rpm drive.
Therefore I think we can safely assume it does come with a 5400rpm 1TB hard disk. However this is not necessarily as bad as it sounds, the whole point of a Fusion drive is to automatically off-load the most commonly used files to the much faster 128GB SSD portion of the Fusion drive so overall you should get performance better than even a 7200rpm hard disk.
Finally, as far as I can see for the Mac mini it does not matter which speed model you buy they will all come with the same 1TB drive model if you chose a 1TB capacity, so the 3.0GHz Dual Core i7, 2.8GHz Dual Core i7, and 2.6GHz Dual Core i5 will all have a 5400rpm 1TB hard disk. -
Processor for graphic design application: dual-core i5 or quad core i7?
I am planning on buying a MacBookPro, and I am comparing the processor options. Using the MacBook for graphic design – Photoshop, Illustrator, InDesign – will I see a significant difference in performance between the 2.6GHz dual-core Intel Core i5, and the 2.2GHz quad-core Intel Core i7? I will typically need multiple files open at once, but I will not be doing any video editing or gaming. If going with the dual-core i5 won’t be too slow, I’d like to save that money! Thanks.
Thanks for answer!
That means I should take the Dual Core (i5),because I don't play games very often.
But Portal 2 should work?!
At the moment I have a PC with 2,4 Ghz Core 2 Quad and it works fine
Please explain with more information -
Is there a noticeable difference between Dual Core i7 and Quad Core i7?
Hi everyone.
I'm going to be a college freshman this fall. I'm looking at 13" MacBook with Retina Display with dual core i7. I'm also looking at the 15" MacBook Pro with Retina Display with Quad Core i7. I want to major in science and have a concentration in photography, which means that I will run programs like Excel, PowerPoint (or keynote), and Photoshop.
Anyways, will there be a noticeable difference between a Dual Core i7 processor and a Quad i7 processor?
Thanks!Ceteris Paribus, the quad-core will be twice as fast as the dual-core.

does the 13-inch: 2.5 GHz 2.5GHz dual-core Intel Core i5 Turbo Boost up to 3.1GHz internet speed the same as the 13-inch: 2.9 GHz 2.9GHz dual-core Intel Core i7 Turbo Boost up to 3.6GHz
The retina MBP will be faster than the conventional one on boot and shutoffs as well as very demanding CPU/GPU intensive applications. As far as web browsing , text editing and other non-CPU intensive applications there will be little if any difference between the two.
If you install A SSD in the conventional MBP, it will be faster than the retina due to the faster CPU. Note also that the conventional MBP can have up to 16 GB RAM installed. The retina is restricted to a maximum of 8 GB.
You will have to weigh the differences in the display, speed, form (weight) and flexibility as to how they suit your needs. All I can do is to and highlight the differences.

Is it worthwhile to replace the hard drive in a 24" 2008 dual core intel iMac?
Is it worthwhile to replace the hard drive in a 24" 2008 dual core Intel iMac?
If you still have a use for it it's definately worth it. You can upgrade the ram to a maximum of 6GB and run the current Yosemite OS. Hard drives are cheap and it's not that difficult, here's a step by step guide https://www.ifixit.com/Guide/iMac+Intel+24-Inch+EMC+2134+and+2211+Hard+Drive+Rep lacement/8968

How to manage a failed OS X Mavericks installation | MacFixIt - CNET Reviews.
Try these in order:
1. a. Resetting your Mac's PRAM and NVRAM
b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and
after the chime press and hold down the OPTION key until the boot manager screen appears.
Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless. -
IS THE SITUATION HOPELESS
I used Target mode to transfer files to a new i7 iMac running Snow Leopard 10.6.8 from an older Dual core Intel machine (EMC 2105) also on 10.6.8. but originally Tiger 10.4. The operation was successful and I ejected the disk icon from the new machine and powered down the old machine. When this was restarted the next day there was a grey screen with flashing Mac symbol alternating with a 'no entry' sign and occasionally a question mark.Keyboard and mouse were unusable so k inserted the original instal disc (No.1 for 10.4. with installer 1.0.4) which came with the machine in 2006 in an attempt to boot from this. The ensuing window said this was not possible and now it cannot be ejected.I have tried everything ! It offers Disk Utility and other options like Terminal but that doesn't work either.I 'repaired disk' and that was pronounced o.k. None of the various keystrokes at start up will work, and the computer will only offer the installer disc continually.The only option would seem to be is to erase the hard drive completely from the disc in the machine.I don't want to do this as there is still material which I need to recover. I think the drive has in some way been corrupted by using it in target mode, and I don't know if there are any other options to try.
Please tell me how to get this disc to eject !Graham Giles wrote:
Have you seen this type of problem before? I think it could be a serious issue for anyone in a similar position.
No; but then, I've not had occasion to use TDM. I've been using firerwire drives for over 10 years, both FW400 and FW800, with no issues except a bit of instability using a B&W G3 machine.
TDM should be safe. Using cautious, manual copying of files from the Target machine to the Host machine should not result in unexpected loss of files or damage to the Target drive's directories. It should behave exactly the same as if it were an external (to the Host) firewire drive.
• I don't suppose there is anything I can do to 'put back' lost items from a separate Time Machine drive which has an up to date backup on it.
There is probably a way to do that - seems to me that's one of the reasons for a Time Machine volume.
On the other hand, if the Time Machine volume is rigidly linked to the now-absent OS on the original drive, there may be no way to effectively access the files in the TM archive.
I know that using a cloned drive would work well in this instance.
I have no experience with Time Machine, so perhaps someone who has will chime in with suggestions.
With the machine in TDM with the other machine, have you tried running Disk Utility to see if you can effect repairs to the drive? -

Not only would it be safe but less expensive as well. The tray loaders are deemed to be the most reliable. Apple does not support Blueray so avoid that.

24" imac dual core and uk broadband providers
I currently have a 17" flat screen imac connected to the internet via the internal modem. I use AOL's dial-up service. I'm intending to purchase a new 24" dual core imac and want to connect to the internet via broadband. As AOL's current broadband sevice doesn't support Macs, can anyone recommend a Mac friendly ISP? I'm a broadband novice, so any other connection advice would be appreciated.
Hi Keithsahammer
All broadband service's are Mac friendly it's most service provider's dont support Mac's.
Have a look at ADSLguide http://bbs.adslguide.org.uk/threads.php?Cat= scroll down for all provider's
Mac forum http://bbs.adslguide.org.uk/postlist.php?Cat=&Board=mac ask away.
When you get Broadband make sure you dont get a USB modem as they dont work to well with Mac's as they need driver's.
Get yourself a ethernet router/modem like http://www.dsl-warehouse.co.uk/product.asp?pr=DG834 or if you need wireless http://www.dsl-warehouse.co.uk/product.asp?pr=DG834G

Can older dual core iMac be external monitor to new (lion) imac
If yes, how do they need to be connected and configured?
Thanks, classic II for the reply. You are right--I should consider configuring my old Mac to be a wireless device if/when I get a new iMac, however I still would need my flash drive to have embroidery designs on it in order to get the designs into xp under bootcamp.
It was painful for me to get my dual core iMac upgraded to 1 meg for snow leopard. I could drive 50 miles to an authorized apple person, leave my iMac and he would order and install the 2 gig memory and in addition charge me $300 to fix the cd drive that was barely off warranty or do what I did. Local apple store would install a half Meg of memory but couldn't do the ordering. So I ordered 500 meg memory from on line apple store, had it shipped to my house, and then had apple store install it--to get me to 1 Gig, so I could install snow leopard--I think the apple store installed it for no charge since I ordered the memory from on line apple store, and didn't have to drive 50 miles, one way--twice.
What I have is working for me, so I guess I'll just watch what happens with lion and icloudI and apple tv (and bernina v6 software which only runs under windows7 on macs) and move on to new iMac when things are settled.
