Imac processor upgrade?

I have bought imac 21.5' with i5 processor a few months ago. Is it possible to upgrade it to i7?

Thanks. Indeed, I had to buy with i7 in the first place.
The reason I bought one with i5 was that several people told me that there were no real difference except a small difference in speed (which was OK with me), as i5 was also multicore. What I found was that even if I run just one very CPU (and, might be i/o extensive) job I do feel some (very small but irritating) delays in responce of other programs, even emacs. I do not have this problem with my MacAir, which has the same memory, but i7. In fact Air also has solid state disk which iMac does not, could this be a problem?
Thanks for responding.

Early 2006 iMac processor upgrade

I have an "Early 2006" Core Duo 20" iMac. I know that the processor can be upgraded (this model was socketed, unlike later iMac models).
My research on the internet concerning this comes up with info that outdated. I know that it is difficult, and I know that the chip needs to be a "mobile Core 2 Duo chip" (those that
My questions are:
1. Has anyone on this board done this?
2. What processors am I limited to, as the info I see is a couple of years old and applies to older processors? I obviously do not want to insert an incompatible chip or one that runs too hot for my logic board & fans (even though I am sure I could use SMC fan Control to help out).
3. Is the old limitation of 2gb ram limited by the 32-bit nature of the Core Duo or by the logic board... meaning if I DO upgrade to a 64-bit Core 2 Duo chip, does that change the 2GB RAM limit?
BTW, these are two of the older articles I've combed through:

Hi Charles
It's a little off the subject, but it would probably cost you less in the long run to sell your Core Duo and buy a New, an Apple Refurbished or Pre-Owned Core 2 Duo.

Processor Upgrade for iMac G3

Hello, I didn't see any particular posts specifically pertaining to the slot loading iMac (Graphite)..I hope someone can help me out.
I have a G3 Graphite iMac, upgraded RAM currently running Tiger. I used to use it but wiped it clean, re-installied the OS and created a separate account for my 8y/o son, so essentially there aren't many apps on there. For some reason it's running slower than it should, even with just Safari open. Is there a fix or possibly a processor upgrade for this model (I keep seeing that there isn't, but I want to be sure).
It's either that or constantly hearing my son complain of the lagtime and ask for our laptops instead...

According to Mactracker at one point there was a 700 MHz model available in Graphite & Snow. If you could find a 700 MHz G3 CRT iMac logic board on eBay it might be possible to upgrade the processor speed. You could also install a Matshita SR-8184 or SR-8186 DVD-ROM drive.
There's firmware available for both drives that allow them to be flashed to RPC1 or region free meaning they can play DVDs from any region in the world. Normally the drive is restricted to being able to only play Region 3 DVDs from the US. If you order a Matshita SR-8184CD optical drive from www.welovemacs.com call their 800 number listed on their website & be sure to ask for Jessica or Faith since some of the optical drives they sell don't have RPC1 firmware available for them.

Imac g4 processor upgrade

I just bought an Imac g4 and I would just like to know if it's possible to upgrade the processor? basic specs:40gb,256megs,700mhz,15" screen.

Hi Macis4me,
Here is a link to an iMac G4 upgrade:

IMac CPU upgrade

I'll just get to the point.
I have a mid 2009 iMac9,1 system. 24" display w/ 2.66GHz C2D with 4GB of RAM and a GeForce9400M.
I want to upgrade the CPU from 2.66GHz to 3.06GHz (or better if available) since I often run demanding applications such as Flash CS4 and MU:LAB (audio workstation) and the extra CPU grunt would be fantastic.
Is the CPU in the iMac9,1 soldered or socketed? Will the Apple store do it for me? I don't want to tackle it myself as I have never taken apart and Apple computer before.
Thanks.

is the CPU in the iMac9,1 soldered or socketed?
Soldered.
Will the Apple store do it for me?
The Apple Store would not perform such an upgrade even if the processor was socketed. Apple does not support processor upgrades in any of their current Macs (they haven't supported a processor upgrade for years, in fact). The only upgrade Apple will perform on an iMac is adding additional RAM.
Sorry, but if you want a system with a faster processor, you'll need to sell your current iMac and buy one of the current models. The Core i7 system is the fastest, but the Core i5 is pretty fast and significantly less expensive.
Regards.

Hello Brad:
First, forget about a virus. There are NO documented viruses that affect a Mac running OS X - none.
Do you have about 10-15% of the HD free at all times?
Open activity monitor and see what is taking the processor capacity.

New Sonnet Encore /MDX G4 processor upgrade?

I looking at New Sonnet Encore /MDX G4 processor upgrade.
http://www.sonnettech.com/product/encoremdxduet.html
Do you think that would make my Power Mac G4 MDD (if I got Dual PowerPC G4 7447A CPUs running at 1.8 GHz) about as fast as my iMac G5 1.8 or my MacBook 1.83 ?

My Dual 1.25 is just as fast as the iMac G5 1.8 it replaced.
Your MacBook beats all of these machines, it is a Dual-Core processor, and it's a newer chip that beats any PPC except the Dual G5's.

Processor upgrades

i have had a single 1ghz mdd firewire 800 for about a year. i had great plans for this machine but it is basically a print server for my g4 imac in the living room. recently i purchased a 400 mhz sawtooth to replace the mdd. Is downgrading from a mdd a good idea? i plan on selling one of the powermacs. if i decide to upgrade again which is easier/cheaper to upgrade? there are a lot more processor upgrades for g4 models earlier than the mdd and i am not sure why. i purchased the mdd for around $400. i purchased the sawtooth for $10.

My LW 16/600 will work with the Wintels if hooked via parallel or via ethernet reversed pair cable (single cable with one reversed pair). But if I hook the LW to a hub or to the router the only units that can see it are the Macs. I just turn on sharing on the Mac and make a printer profile in the Windoze control panel that routes to my mac (\\xxx.xxx.x.xxx\<mac name>\<OSX printer profile>). I imagine it has something to do with the protocols back in 1995 when the HP4 was being made as a LW.
But if you say that your HP5 will show up when hooked to a hub but not a router I may try that, isolate the Wintels and the LW on the hub and then hook the hub to the router. Is that essentially what you are describing? A reversed pair cable is a two unit closed loop hub, so the same effect as I described before will apply, right? But current setting of letting OSX discover the LW and letting the Wintels use the Mac to print is no real drag, just a few watts of power for an otherwise unused computer.
My HP LJ5MP worked with the PhoneNet/EtherMac connection to its AppleTalk port back when I just used the old 10BaseT hub for my LAN and internet connection (before modern router and switches). However, the new switch technology doesn't recognize the EtherMac output, which is the AppleTalk input. I found that when I put the hub in between the EtherMac and the new switch, the switch recognized the hub, which recognized the EtherMac and everything worked on my LAN. With this setup, both my Mac and my PC notebook on my LAN could see and use the HP LJ5MP.
Alternatively, I later bought a D-Link parallel port print server for the HP LJ. It works quite well on my LAN and is a little bit faster than the AppleTalk/EtherMac/hub setup. I currently have both connections to the HP LJ 5MP hooked to my LAN. I do it for redundancy, as the two different connections function independently of each other, so if there is a problem with one, the other usually works. This is important to me as the HP LJ is my primary printer for all my computers.

Imac Core Upgrade??

How would I go about upgrading my Imac, which is capable of holding two cores?
Do I have to buy the processor from Apple or are there equivalents on that I can buy online?
Thanks in advance,
Jason

The core is not a user upgradeable part. That means there is risk any upgrade to the core will void the warranty. I say risk, since none of us here works for Apple, but are aware of the part of the warranty which discusses "unauthorized modifications", and can't really state Apple's policy for certain due to terms of use on the right. Thus if you want to do a processor upgrade, you'd best take it up with AppleCare, if you still have an under 1 year old machine, or one you purchased AppleCare for to make sure you don't run into trouble. http://www.xlr8yourmac.com/ is the most thorough site I've come across to discuss processor upgrading. Cooling is a big concern because many of these machines have very specific fan speeds to keep them cool, and cooling gel which when applied too much becomes an insulator and overheat, and too little would overheat too. Thus any such installation is pretty much at your own risk.
In addition, because each model has very specific hardware/software integration, it is possible you may make it impossible to upgrade your software once you install a new core, as the software won't be seeing the hardware it expects.
If you really want to upgrade the speed of your iMac, be sure to spec RAM (x), and consider keeping your hard drive at most 85% full (x) (an arbitrary number), as that slows down the system. Also keep your active Dashboard Widgets to a minimum, and use your USB bus wisely with the Apple System Profiler to make sure not too many 12 Mbps or slower devices share the high speed bus.
(x) Links to my pages may give me compensation.

IMac G4 Upgrade

Hello. Is it possible to upgrade an old iMac G4 to the level of modern computer? Now processor in the iMac G4 is very weak (1.25 GHz PowerPC G4).
Thank you!

As others have said, the answer is basically no. You can add RAM, but that won't get you any closer to current as far as application compatibility or running a more modern version of the OS.
Your best bet would be to look at a new machine. I know it's expensive, but you're getting a lot more than just a processor upgrade. Since the days of the G4 iMac, just about every component (or subsystem) inside the machine has seen some major improvements. Not just a faster CPU and more memory, but a MUCH faster graphics chip (even the least expensive iMac has a fast GPU), faster (and larger) hard drive, better display, and even improved I/O (stuff like USB ports). You also get the latest version of Mac OS and iLife, it's quite a bit of bang for your hard-earned buck.
To get an idea of how much faster a new machine might be overall, you can take a peek at the GeekBench (Mac Benchmark app) results. An 744MHz iMac G4 gets a score of 349, which wasn't bad back in the day. The lowest score of any of the 2011 iMacs is 7,185. Yes, that's 20 times faster.
Hope that info helps!

I can't set up iCloud drive on my iMac after upgrading to Yosemite

I can't set up iCloud drive on my iMac after upgrading to Yosemite - iPhone and iPad are updated but both say my iMac isn't (even though it is running Yosemite).
My iMac is OS X Yosemite 10.10 (14A389), memory is 4 GB 1333 MHz DDR3 and storage capacity is 273.64 free of 999.35 GB.
When i go to System Preferences and click on iCloud. The iCloud Drive section is greyed out and says setting up and a spinning pin wheel. It stays like this the whole time. I have tried restarting the computer. i amanita sure what else to do to make it work. Any suggestion would be great.

I found another way to correct this...
1) Select Message, then go to Preferences,
2) a window will appear with 3 options, General, Accounts, Audio Video, don't be surprised when you see a video of yourself, your camera just turned on.
3) Select Accounts (you may have several here)
4) Select the account that has "iMessage" under the account name. This may likely be your Apple ID ****@me.com
5) Look at what is checked under the "You can be reached for messages at:"
6) Select the one account (or more if you like) and deselect the others
7) Close the window and the problem goes away.
I'm not longer getting my sons iMessages.

How do I turn off messages on my iMac after upgrading to Yosemite?

How do I turn off messages on my iMac after upgrading to Yosemite?

Hi,
Open the Messages app.
Go to the Preferences item in the app's Menu.
Select the account pane in the Preferences.
Each active account should have a tick in the Enable this Account box.
This can be unticked.
This will stop accounts logging in but will not stop the app Launching in certain circumstances.
First of all check the app is Quit before shutting down the computer.
The fact the app is open even if all windows are hidden can cause the app to restart when you Start up the computer.
Messages is a Multiple window app and using the red button on the top left of a window only closes that window and does not Quit the app.
Also check the System Preferences > Users and Groups > your account > Login Items tab.
This will list items that are set to Start up when the computer does.
I have a couple of External Drive on other computers, some Anti Virus software and the common iTunes Helper plus an old version of TextExpander that will work if I launch the Preference Pane this way.

iWeb 'disappeared' from my iMac after upgrading to OS X10.8 - any ideas? tkx

Did you do an erase and install of Mt Lion? In any case you'll have to reinstall iWeb from its original source. Did iWeb come with your computer? If so you should have a couple of disks that came with your Mac and one of them will have the Bundled Software Install package on it. Like one of these:
Be sure to update iWeb to the latest and last version, 3.0.4, from Apple Downloads web page.

SCSI card for a G5 or processor upgrade for a G4?

Hi all
Actually, this is a question that concerns the G5 and the G4 forum, but I decided to post it here first.
So, I have this old G4/400 PCI with an Adaptec 2930 SCSI card that I use for scanning slides with an Artix 4000t sclide scanner; this works fine, but the G4 is rather slow when it comes to using some features of the scanning software, such as removing scratches.
I've been thinking about buying a SCSI card for my G5 (Dual 1.8) for some time now, but I'm not sure what card I should go for; I'm not even sure if there are still cards for such an "old" device as the slide scanner (about 3 to 4 years old, no Ultrawide or something like that). And then there's the problem of the drivers for the card - how long will they be available, especially now that Apple is switching to Intel...?
The other possibility would be to buy a processor upgrade for the G4. I've seen some at OWC, and they seem to be less expensive than a SCSI card. The drawback of this solution is of course that I'll have to keep the G4 standing on my desk... on the other hand, I do know that the scanner will work perfectly with the G4.
The G5, on the other hand... it will be faster and easier, since I won't have to transfer the files for storage and editing, I could free some space on my desk,... but will it work? The G5 is running 10.4, I'm not sure if my current scanner driver is compatible... and what when 10.5 comes out...?
So I'm looking for a second, third, fourth... opinion:
What would you do? Get a SCSI card for the G5 or a processor upgrade for the G4? What SCSI card would you recommend?
TIA,
Tina

I've done some research on G5 and SCSI and scanners, and obviously, what I remembered was correct... making it work seems at least tricky, and maybe expensive too (if you've got to buy new scanning software and and..).
So I guess that's decided: No SCSI on the G5. Leaves the question, should I buy a processor upgrade card for the G4? Getting some dual G4 on eBay might be an option, but then, that would be another computer in my already crammed office, and I just can't throw the G4 away, it's one of the very first models...
I came by the idea of a processor upgrade because I just played around with an old Mac SE, which has an 68030 accelerator card installed, and this seems to work fine. Anyone has any experience with G3 /G4 upgrades (good or bad)?
Smokerz: Why would you not recommend an upgrade? Any bad experiences?
