Connecting 3rd Party Monitor to iMac 2.8 Intel Core i7 27"

Hi Hope somone maybe able to answer this question?
I would like to connect my Dell monitor to my iMac as a 2nd screen, it has VGA, HDMI, & DVI ports. What would be the best way, can I simply purchase a mini-display port > DVI or VGA adapter or would I require a Dual Link Adapter?
Thanks in advance
Mike

A mini display port cable to either HDMI, VGA or DVI would be fine. The best way to to purchase is to buy it directly from Apple that way you know you are getting a high quality cable that has been well tested.
BTW, your manual says:
One or two Thunderbolt ports (high-speed data, video, and audio)
Connect Thunderbolt-compatible devices for high-speed data transfer, or connectan external display that uses Mini DisplayPort. You can purchase adapters to connectdisplays that use DVI, HDMI, or VGA. The 21.5-inch iMac has one Thunderbolt portand 27-inch iMacs have two.

Connect third party monitor to iMac thunderbolt

Trying to help my brother find some answers. He is going to purchase the newest iMac and knows that a monitor can be connected via the Thunderbolt port, but needs to know what kind of adapter he might need to connect a third party monitor.
Any help will be appreciated
Thank you in advance

He needs a Mini Display Port to either VGA, DVI or HDMI adapter. The MDP and Thunderbolt connections are the same size. If he wan't a really nice external monitor tell him to get the Apple Thunderbolt Display. Those retail for $999 but can be found on Apple's refurbished store for $849 which is a good buy.

Trouble connecting 3rd party monitor to MacBook..."OSD Locked" message?

I am trying to connect my LG monitor to my MacBook air. This monitor worked w/the last MacBook I had (2008 model) and yes, I am using the right cable. The background on the monitor is the same as my MacBook (starry galaxy image) however there are no files. When i tap any button on the monitor (e.g., menu, engine, source, auto/set) I get the message "OSD Locked". I have a feeling this is a setting from my MacBook. Any ideas?

Hey wrtrgrl,
Thanks for the question. It sounds like everything is up and running, your preferences may just be set to Extend your Desktop (as opposed to mirroring). Try configuring your preferences to mirror:

Forwarding alerts to a 3rd party monitoring tool

I'd like to be able to forward alerts recieved by the Enterprise Controller to our Unicenter NSM server. I have no desire to use Ops Center's incident assignment capabilities.
Has anyone managed to forward alerts from Ops Center to a 3rd party monitoring tool ?

Since posting my question, I have found this possible solution...
http://www.halcyoninc.com/products/NeuronIntegration/index.php
Halcyon appear to be an Oracle partner who have developed a product which integrates OC with popular 3rd party tools.
I see also that a user by the name of 'halcyon' sometimes posts in this forum, so I'm guessing that's them also.
Obviously this is a commercial solution and won't come for free, but I have struggled to figure out how this can be achieved independently. As you say, there are lots of questions and documentation is sparse. I'd prefer not to make a career out of it. ;)
The integration of OC with our Unicenter NSM tool with be my highest priority for when I get back from Xmas vacation in mid January. I will post up any useful information I discover.

One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.

IMac 3.06GHz Intel Core 2 Duo (24-inch) - 2 or 4 slots ?

Hi,
Crucial's memory selector tells me that I can install a maximum of 4GB of memory on my iMac 3.06GHz Intel Core 2 Duo (24-inch). Why does the system info show me that I have 4 slots with 2 being empty (see picture below) ?
Regards.

Hi,
I found the reason why System Info is displaying 4 slots ... it's because I have 4 slots.
I have a 21,5" monitor not a 24". It is identified as an iMac10,1 model and the good news is that I can upgrade to 16Gb of memory.
That being said, I would like to upgrade, because I often find that my computer is slow. If I go to the Activity Monitor utility, iI think that my memory requires an upgrade but how much more should I put in ? See the memory display below.
Also can someone tell me if I could experience a faster computer if my processor is not used intensively, like shown below.
Regards.

IMac (3.4gHz Intel Core i7) shuts down when sleeps, then won't restart

Just bought a brand new 27" iMac (3.4gHz Intel Core i7) which shuts down when sleeps, then won't restart (ie completely dead).
In order to restart, I have to unplug the power cord from the computer, hold power key down for 10secs, replug in and it then starts up. I returned to the store and they spent a couple days letting it go to sleep etc and overnight and for them it was fine. Woke up no problems. They returned it to me yesterday.
So I set it all up again, left it overnight and this morning it was dead again. So now it leaves me to wonder if it's something I have plugged into it.
I have a new Seagate 3TB external hard drive hooked up using USB3.0. This is plugged directly into the back of the computer.
I also have a powered USB hub plugged into the computer which has regular USB stuff such as printer, graphics tablet and another external hard drive (this one is older LaCie 500gb, and have put it into a new USB 3.0 case as well for the arrival of the new iMac (this had an old firewire hard drive case). However this hard drive is switched off at the case and is not being used.
I believe it could possibly be the Seagate 3TB disk causing this problem, but it works fine during the day while I am using the computer, it's just when I either leave it at lunch time to go to a meeting or walk etc or overnight that I come back and it has shut down....leaving me to believe that it's due to the computer going to sleep.
Has anyone else had a similar problem with a Seagate drive? Today I'm conducting an experiment and heading off for lunch with both hard drives unhooked. If I come back and the computer wakes up from a click of the mouse or keyboard as it should, I will plug in one hard drive at a time and re-test. I will leave the Seagate for last, as I don't think it is the old LaCie disk (which is off).
For reference sake, I also have a NAS running off my network through Airport Extreme etc and have my old iMac hooked up to the network too, but don't believe this is the problem.
Initially I did put in some after market RAM (another 8GB) and though that might be the problem, but I removed and it still reacted the same way (plus store I bought it from again booted up fine and woke up fine at their shop after I had taken RAM out too).
Will keep this post updated with my next test (letting computer sleep without either hard drive in), but keen to hear if anyone has had any similar experiences with Seagate disks/cases and the new iMacs.
Cheers,
Kristin

Hey kristinandmike,
I had a similar problem shortly after I bought my 27" iMac. Here is an excerpt from my discussion:
"As BDAqua suggested, I started the process of elimination by shutting down the externals and just leaving up one of the USB drives and using the computer until time to shut it off. After eliminating 2 of the 3 drives I figured it had to be the last one. That drive is a Seagate GoFlex Desk version that allows different bases with differing connectivity. I had previously used FW800 to connect but had switched to USB3 on the new computer. I went ahead and got a Thunderbolt to FW adaptor cable and switched this drive back to Firewire rather than USB3. So far so good."
For some reason the Seagate I was using didn't agree with the USB3 on the Mac.

10.10 painfully slow on 2008 iMac 2.4gHz intel core 2 duo

I made a big mistake-
My gf sees me as the guy who really knows Macs.
I updated her 20" iMac 2.4gHz intel core 2 duo (3G ram) when the prompt came up in software updates.
Now she's practicing patience as everything is much slower and problematic in keeping connected to the ISP.
Accepting that the Mac has to re-index everything, we've allowed 3 days for this, but not much improvement.
The question:
What is Best Practices (and detailed method) for getting back to her previous OS without the install disk?
This is probably best until we can get a new Mac on her desk.
Is it better to stay with 10.10.1 - if so, we need to speed this puppy up.
Any help?

The first problem may arise from the fact that iMacs use 3.5" harddisk whereas most SSDs are 2.5" ones.
So some sort of tray or 'holder' is needed.
Second problem might be the thermal sensor Apple uses in some iMacs.
Your first recommendation to your friend: 'get a bigger harddisk and more RAM' sounds like the best way.

Your Mac is definitely one of the supported models? http://www.apple.com/uk/osx/specs/
If so, what happens when you try to download? Is it a case of nothing happens? If so, take a look at the suggestions under 'Stalled Download' in this link:
http://www.wired.com/gadgetlab/2013/10/mavericks-issues-and-fixes/#slideid-23477 1
Also, some usrs have found that logging out of the Mac App Store and then back in again and starting over has kick-started the download. It seems that the 5+gb download can take a long time to give any feedback as to what's happening.

I'm currently running OS-10.6.8 on my IMAC with an Intel Core 2 duo and would like to update to at lease 10.7. Can this be done and if so how?

Only if you cannot upgrade to Mavericks.
Upgrading from Snow Leopard to Lion or Mavericks
To upgrade to Mavericks you must have Snow Leopard 10.6.8, Lion, or Mountain Lion installed. Purchase and download Mavericks (Free) from the App Store. Sign in using your Apple ID. The file is quite large, over 5 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 Mavericks- System Requirements
       Macs that can be upgraded to OS X Mavericks
         1. iMac (Mid 2007 or newer) — Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) —
             Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) — Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) — Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) — Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) — Model Identifier 3,1 or later
         7. Xserve (Early 2009) — Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Are my applications compatible?
         See App Compatibility Table — RoaringApps.
Upgrading to Lion
If your computer does not meet the requirements to install Mavericks, 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.

How much Memory Should my IMac have? iMac, 24-inch, Intel Core 2 Duo

Hi, I have a problem. I have a iMac, 24-inch, Intel Core 2 Duo which had to have a hard drive replaced. Brought it home today and it is not the same? It makes weird noises when processing info and it seems to run slower. I noticed that the memory is only 1GB and this model should have 2 or something along those lines? It seems as though they didn't replace this with what I had on my original one? Can anyone help me, let me know how to verify that I am lacking what I had on this machine when I bought it and what should this model have on it? I am so ****** off right now, it isn't funny!
Also, I can't go into my Iphoto and make any of my pictures a desktop image. That leads me to believe it is a low memory issue. Right?

What imac do you have how old is it. The 2.4ghz 20inch model still comes with 1gb as standard in the uk anyway. most intel imac including mine are totally silent, is it overheating download a great widget called istat pro at http://www.apple.com/downloads/dashboard/status/istatpro.html this will show you your fan and temp etc. If it in warranty then take it back to apple or phone them with the machine serial number and they will inform you to what spec the imac was shipped to you. The desktop image problem - go-to system preferences then to desktop and screen saver you will find all your iphoto folder and events in the right hand side just click on your image this should work.

Hi,
This is the compatibility list
http://www.apple.com/osx/specs/
if your iMac is mid2007 or newer - yes.
You will need to upgrade to 10.6 (Snow Leopard) first buy DVD from online apple store
Then to 10.7 Lion - buy and download via Store App included in SL
and then 10.8 Mountain Lion upgrade the same steps as Lion

Is RAM and OS for iMac 2.16GHz Intel Core 2 Duo upgradeable?

Can the RAM and OS for a iMac 2.16GHz Intel Core 2 Duo with 1GB RAM, 667 MHz DDR2 SDRAM, MAC OS X 10.6.8 be upgraded? Looking to upgrade to 4 GB RAM and OS X 10.8. Please advise. Thanks.

Welcome to Apple Support Communities
Of course you can upgrade RAM. You have a Late 2006 iMac, which supports 4 GB of RAM. You can buy more memory at OWC or Crucial > http://eshop.macsales.com/shop/apple/memory/iMac/Intel_Core_2_Duo_2006
This Mac can't be upgraded to OS X Mountain Lion because OS X Mountain Lion needs a Mid 2007 or newer iMac. Instead, you can upgrade to OS X Lion by calling Apple > http://support.apple.com/kb/HE57 Make a backup of your files with Time Machine and check that your applications are compatible > http://www.roaringapps.com
