My 2009 iMac started behaving very oddly. On the computer, we have four user profiles set up two of which are admin users. A couple of months ago I noticed that under my user ID(Admin) I'm not able to access the internet but under the other admin ID the internet can be accessed. I have a...

Hi there, I have acquired some iMacs from 2009 which have had windows 7 put on them for whatever reason. I'm trying to get macOS back on them but whenever I boot them up (current OS is corrupted btw) I get a blank grey screen followed by the PC style 'No boot device available press enter to...

I know this discussion has been had 1000 times, but I'm yet to find a clear answer. To my knowledge, the Core 2 Extreme X9000 does allow the iMac to boot up, but its under clocked to 700MHz. I know this, and it would be simply unacceptable to run this in macOS. However, to my knowledge, this...

Good Morning, I have a late 2009 iMac, which I recently upgraded with 12GBs of memory and a SSD hard drive to give it new life. I just upgraded my internet to 1000Mbps. I was wondering if there was a way to upgrade my computer to handle speeds anywhere near that via WiFi. Can I just upgrade my...

Hey y'all, I've got a strange issue. I purchased a used iMac a couple months ago and it was working fine then. Everything booted fine and stuff.

Hello, I followed the instructions from "https://forums.macrumors.com/threads/adding-usb3-0-to-late-2009-imac-11-1.1979806/#post-26064070" which were limited but gave me a lot of hope. But, after doing it all I find myself with 2 more USB 2 ports. Basically the system identifies a USB 3...

I have a late 2009 Imac lying around gathering dust ... I had decided to upgrade it, so I upgraded the ram to 16gb and put in a 512gb ssd- now I want to go further. I know that it has a core 2 duo, but would I be able to put in an i7? And if not, what it the best processor I could put in? I know...

Hi there, I want to buy a cheap used mac for Adobe Lightroom (5,6 or CC. I would use it for 10MP RAW files from a Canon 40D) and I found an iMac with these specs: iMac early 2009 24 inch 2,66 GHz C2D 4GB DDR3 (please tell me if it makes sense to add more RAM) GeForce 9400 w/ 256MB RAM I also...

Hi been lurking round here for a while and found a lot of help for various issues over the years without having to post. But I can't seem to find a solution for this one. I have a 2009 iMac running OX 10.8.5 over the last few weeks it keeps ejecting one of my 3 external hard drives. A WD 3...

Hi folks, I'm new to this forum, and have very limited experience with upgrading computers, with the exception of RAM and battery replacements. I own an early 2009 20-inch iMac, 2.66 GHz Intel Core Duo, running OS X 10.9.5. I upgraded the RAM two years ago to 4 GB (1067 MHz DDR3). As one might...

I have a late 2009 27" iMac with blue vertical lines. I opened it and tried to bake the video card and put it back in but I got a blank screen with the backlight on. I connected my iMac to TV to see if the video card is toast but it showed up okay on my TV screen. I bought a display port cable...

Hi, as I see a lot of people trying to achieve the same thing on his old imac 27'', and searching the net trying to see if someone has already done this, we end up here thinking it's not possible to swap the mini pci-e wifi card, I'll update with my experience: it works, you can have usb 3.0 on...

The display on our iMac 9,1 (vintage 2009) (OS 10.9.5 or so) went black. At boot I hear no chime, but I see a brief 1 cm horizontal illuminated band then just more black screen. I can boot it into target disk mode. Having done that, I connected it to a MacBook Pro running the same OS and ran...
