Upgrading iMac 2007 (7,1) Memory

I seem to find my trusty iMac a bit sluggish and want to upgrade the RAM (that and i was given a copy of Windows 7 as a gift) so 1 gig isnt enough to run two modern OS's. I've been doing a lot of research (making sure i know what i'm doing and making sure i don't screw up) and I know what kind of RAM to get and how to install it and everything.
what i'm not sure is if I remove the previous DIMM (1 gig) and put in a 2 gig DIMM, would 1 gig be subtracted from the new DIMM as it would occur in a PC? Since i'm hoping to max out my machine with 4 gigs, i'd really like to know before i shell out the cash for two 2 gig DIMMS and instead opt for just one 2 gig DIMM.
thanks in advanced, i always appreciate the help i get here!

Hi sceptile2300
Your iMac supports a total of 4GB, 2 2GB modules, see > http://support.apple.com/kb/HT1760
I saw a 1GB PC2-5300 667MHz PNY ram module at my local BestBuy for like $55, but really your best buy is at OWC > http://eshop.macsales.com/shop/apple/memory/iMac/IntelCore_2Duo

Hi,

Many Thanks

Sorry no it is not.

I have OsX 10.6.8, and imac 2007-08, and enough disk space to download yosemite but still Apple tells something is wrong and generates a list of maybes but not a specific reason. Any ides as to how to pin point the problem of the upgrade?

Want to upgrade from 10.6.8 to yosemite and I have a imac 2007, and enough disk space. but when trying to download, I get a "I can't" due to a list of possible issues, but how to isolate the problem?
Thanks,

Check that your computer is compatible with Mountain Lion/Mavericks/Yosemite.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
iMac (Mid 2007 or newer) model number 7,1 or higher
Your Mac needs:
OS X v10.6.8 or OS X Lion already installed
2 GB or more of memory (More is better - 4 GB minimum seems to be the consensus)
8 GB or more of available space
Check to make sure your applications are compatible. PowerPC applications are no longer supported after 10.6.
Application Compatibility
Applications Compatibility (2)
Do a backup before installing.
If you can/do upgrade, I recommend you make a copy of the installer and move it out of your Applications folder. The installer self-destructs. The copy will keep you from having to download the installer again. You can make a bootable USB stick to install using this free program.

I recently upgraded my 2007 vintage iMac from the Leapord OS to Mavericks. Now my system runs extremely slow when I start my apps. I only have 2G RAM. Do I need to install more RAM or is this something else?

I recently upgraded my 2007 vintage iMac from its original Leapord OS to the new Mavericks OS and now its really running slow. I've run disk utilities to confirm everything is ok from the hard drive standpoint ... but am wondering if this is simply a memory issue. I only have 2G of DDR2 SDRAM installed. Is there a minimum recommended for the Mavericks OS? Any other recommendations? Time to launch any app has more than tripled from what it was before the OS upgrade.

A combination of things:
1. Slower CPU and GPU.
2. Not enough RAM installed.
3. Upgraded from Leopard.
I would have backed up my files, erased the hard drive, then reinstalled Snow Leopard. Downloaded Mavericks and upgraded Snow Leopard directly. Then I would restore my files.
Upgrade your RAM to at least 4 GBs if supported by your model.
Backup your files, then do the following:
Install or Reinstall Mavericks or Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
OS X Mavericks- Erase and reinstall OS X
OS X Mountain Lion- Erase and reinstall OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.

I have a imac 10.5.8 with 1 GB of memory. If i upgrade to 3 GB of memory will i then be able to run mountain lion ?

What year, CPU speed and screen size is your iMac?
It appears as if it's one of the 2006 models that can only take up to 4 GBs of RAM, but only 3 GBs is recognized.
3-4 GBs of RAM is really the working minimum amount for OS X, alone.
The minimum iMac hardware spec for OS X 10.8 Mountain Lion is a mid 2007 model iMac.
2006 models cannot run Mountain Lion, but can run OS X 10.7 Lion.
If you have a mid 2007 or newer iMac, my advice would be to install, at least, either 6 or 8 GBs of RAM.
OS X, by itself, to run smoothly,quickly and efficiently can use between 3-4 GBs of RAM leaving virtually no RAM for any additional applications.
If you have an iMac that can take more than 8 GBs of RAM, think of installing more if you can afford it.
Purchase reliable Mac RAM from online vendors Crucial or OWC (Other World Computing) also known as macsales.
Good Luck!

I have an iMac (2007) with osx 10.5.8, I would like to upgrade to mountain lion 10.8. Is it possible?

I have an iMac (2007) with OSX 10.5.8 and I want to upgrade it to mountain lion. It tells me I must have OSX 10.6 or higher but it won't let me upgrade to that. Is it possible or do I have to buy another iMac? Love my iMac! I'll never have a PC again. Macs all the way.

Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s MobileMe service; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
        1. iMac (Mid 2007 or newer)
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer)
         3. MacBook Pro (Mid/Late 2007 or newer)
         4. MacBook Air (Late 2008 or newer)
         5. Mac mini (Early 2009 or newer)
         6. Mac Pro (Early 2008 or newer)
         7. Xserve (Early 2009)
     Are my applications compatible?
         See App Compatibility Table - RoaringApps.
     Am I eligible for the free upgrade?
         See Apple - Free OS X Mountain Lion upgrade Program.
     For a complete How-To introduction from Apple see Upgrade to OS X Mountain Lion.
Note that you need a specific 2007 model to run Mountain Lion.

It takes forever opening folders ... (iMac 2007 - Leopard)

In fact, everything is slowing down, but I can live with that, except for opening existing folders or naming newly created folders.
Is it usefull to upgrade to Snow Leopard (> Mountain Lion) to speeding things up?
iMac 2007 (iMac 7.1) 2.8 GHz 4GB Memory HD 465 GB (170 GB Free)

Open Activity Monitor, Show:>All Processes, sort on CPU%, see if anything using too much CPU% when this happens, click on Memory tab, do you have many Pageouts?
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...

Problem: slow connection. I have an iMac (2007) running on Mac OS X 10.6.8. I just had my internet speed increased from 1 to 3 Mbps but my connection slowed down considerably. Do I have to change any setting?

Problem: slow connection. I have an iMac (2007) running on Mac OS X 10.6.8. I just had my internet speed increased from 1 to 3 Mbps but my connection slowed down considerably. Do I have to change any setting on the computer, and how?

One possibility is that you may need to "Upgrade" your Cable /DSL Modem if you have an older unit. ISP's that provide your Internet service in recent years have been switching over from DOCSIS 2.1 version Modems to DOCSIS 3.0 version Modems, which handle the new higher data streaming speeds the ISP's are offering. I would suggest you call your ISP's Technical Support and inquire about this possibility.

I bought used iMac 2007 with Mavericks installed but iPhotos was missing. I reinstalled Mavericks but didn't get iPhoto. Now if I want it I have to buy it? Is there a way to install it without having to pay for it?

If you own any verson of iPhoto '11 then there is a free update to version 9.5.x in the App store
If you own a previous version of iPhto (iPhoto '09 or earlier) then as always an upgrade to a new version (in this case iPhoto '11) is a paid upgrade and you purchase it in the App store
and no OS update/upgrade contains a version of iPhto - it is a seperate program and although it is included as part of every new Mac it is not a free program and never has been sinve version 1 or 2 (I forget when it changes)

Imac 2007 and maverick will be compatible

With all the description of maverik, I have the impreion that my imac 2007 dual core will roon better, or this will only apply to i5 up cpu. Will I have full compatibiliy will the apps? thank!

OS X Mavericks has got the same requirements as Mountain Lion. Just open System Information or System Profiler app (in /Applications/Utilities) and check your model identifier. If it's iMac7,1 or a higher number, your computer is compatible.
We don't know anything more about OS X Mavericks, so you will have to wait until the final version is released to know if your computer will work properly. Note that this version includes a huge number of performance improvements and a better memory management, apart from OpenGL 4 compatibility and more. See > http://www.apple.com/osx/preview

Imac 2007 and bluetooth setup

Hi,
I just bought a pre-owned imac 2007. The computer is rebooted/re-installed and I am now sitting with the welcome screen before me. Is there a way to pair the bluetooth keyboard and mouse at this stage or do I need a USD set to finalize the setup?
Thanks,
Emil

Want to upgrade iMac os x 10.5.8. suggestions as to what next best version I should go to?

Want to upgrade iMac os x 10.5.8. suggestions as to what next best version I should go to?

If it is a PPC iMac (G4 or G5) Leopard 10.5.8 is as far as it can go.
If an Intel iMac, read on:
Start by checking if you can run Snow Leopard:
Requirements for OS X 10.6 'Snow Leopard'
http://support.apple.com/kb/SP575
The OS 10.6 Snow Leopard install DVD is available for $19.99 from the Apple Store:
http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
and in the UK:
http://store.apple.com/uk/product/MC573/mac-os-x-106-snow-leopard
When you have installed it, run Software Update to download and install the latest updates for Snow Leopard to bring it up to 10.6.8, or download the combo update from here:
http://support.apple.com/kb/DL1399
Check via Software Update whether any further updates are required, particularly to iTunes.
You should now see the App Store icon in iTunes, and you now need to set up your account:
http://support.apple.com/kb/HT4479
You can now upgrade to Mavericks OS 10.9 for free IF you have one of the following Macs, with not less than 2GB of RAM, and at least 8GB of available space on your hard drive:
iMac (Mid-2007 or later)
MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
MacBook Pro (13-inch, Mid-2009 or later), (15-inch, Mid/Late 2007 or later), (17-inch, Late 2007 or later)
MacBook Air (Late 2008 or later)
Mac Mini (Early 2009 or later)
Mac Pro (Early 2008 or later)
Xserve (Early 2009)
If you cannot run Mavericks you can purchase the code to use to download Lion from the App Store (Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, running the latest version of Snow Leopard):
http://store.apple.com/us/product/D6106Z/A/os-x-lion
or Mountain Lion:
http://store.apple.com/us/product/D6377Z/A/os-x-mountain-lion

IMac 2007, crashes

My iMac 2007 keeps crashing, forcing me to conduct a cold reboot on each occassion. (Unplug machine wait 15 seconds, hold down power button for 5 seconds , etc) Should I upgrade to Mountain Lion to help resolve the problem? or are there any specific tests I can conduct to diagnose the fault?

No what you need to do is isolate whether it is software or hardware causing crashes. You can't upgrade an unstable system anymore than build on an unsteady house of cards. Backup your data and then we can isolate the causes of the crashes.

Random crashes imac 2007

iMac 2007 (I bought it in August 2007) has a strange series of random crashes every two days and with differents tasks (Safari, Pages, IPhoto etc...). Suddenly and for no apparent reason, the screen freezes. It doesn't obey any order from the mouse or the keyboard... We have to force reset by switching off and so many times with the subsequent problems for de HD. We change the RAM to see if the problem was there and no way. Later on we have to change the HD because as a result of so many crashes the HD was nearly broken. We change the keyboard, the mouse... We delete the HD and we reinstalled from the original DVDs that came with the iMac... Then we upgrade to 10.6.8 and the same problems. We upgrade to 10.8 and the same problems... and this happen for nearly a year...
Apart from these random and continous crashes the iMac goes smoothly when it has a day without crashing out.
My question: does anyone know if this problem is recognize by apple as a manufacturing problem with these series of iMacs?
does anyone know a way to solve the continuoys crashes?
Thanks in advance for your posible answers. Sorry for my faulty english. It is not my mother tongue.
with my best regards.
Thanks.

No. I have no anti-virus software of any kind.
thanks
