I have a 27" 2010 iMac that has served me well since I bought it new. It sees only light duty; web surfing, email, Microsoft Office, and a touch of Photoshop LE. Lately, however, the hard drive is making noises that sound a lot like boiling water. I'm considering a 1TB SSD upgrade from OWC for $220. I've done plenty of hard drive upgrades but never on an iMac. I upgraded the RAM long ago from the original 4GB to 12GB. If I do the SSD upgrade and completely screw the pooch then my upgrade path is clear: new iMac. I'm thinking for $220 it's worth a shot. I also have a new 2020 MacBook Air so I won't be Mac-less if things go horribly wrong.

Honestly if you need the speed and updates, upgrade. If not, get the SSD and hold out until ARM. My 2012 iMac is doing great and I will be using it until it is no longer sufficient for my uses then upgrade to the newest iMac.

Is the K3100m compatible with the 2010 iMac? Like plug-n-play compatible?
Almost. The vBios has to be flashed. But if you can tear down an iMac and put it back together, flashing the vBIOS is not that hard. There are a few ways to do it (Linux, Windows 7, or a CH314 programmer).

Seems pretty straight forward, especially with nvflash now supporting Windows 10. Where do I get the bios file for the card?

I've just bought a 2nd iMac 27" mid 2010 on Monday. (300$)
Origin specs:
Core i3-550
2x2GB DDR3 RAM
HD5750m
500GB HDD

My intention for upgrade:
- 120GB SSD to replace the optical drive (have a spare lying around), re-use the temp sensor of the optical drive.
- core i7-870 (30$ incl shipping)
- 2x8GB DDR3 (55$)
- K2100m (65$) or K3100m (80$)
- Having a service shop do all of the above upgrades (30$) and cleaning.

Or I might skip the GPU upgrade and have the original GPU rehabilitated, i.e. removing all the aged solder on the GPU chip and re-balling, resoldered it back to the MXM card. Almost all laptop repair shops here have a special machine to rebake just the GPU chip on the card, thus the service is very cheap.

What do you think? Am I very stupid to purchase such old hardware and upgrade it?

Like @herrdude said, don’t reball the GPU, just replace it. Also, making the SSD your boot drive and the extra RAM is going to do wonders — and that’s before the CPU. For $200, you're basically replacing every single component, but you’ll be left with a much more usable machine and a very good QHD display that can be used in target display mode. Honestly, I’m mad I let my husband sell my late-2009 27” iMac for scraps like 5 years ago because I would still use it as a random display today.

I'm curious, where can you get a service shop to do those upgrades and cleaning for $30? I would love to have someone else do an SSD upgrade on our 2009, but I figure they would charge much more than that amount around here

I live in Ho Chi Minh City, my friend. Repair shops are plenty and service prices are cheap here.
The other day, I've asked for a quotation for my iMac:
- Thorough dusting.
- Reapplying thermal grease for CPU & GPU
and they offered me 10$ for the service, so I guess for another 20$ they would help me swap the GPU, flashing it as well.

Their website is in the link below, all in Vietnamese. But the shop is just 20min from my house.

The bake may not work at all, or may only last a short while. It is a temporary fix, but that temporary fix could last for years.

The GPU bake that I did has lasted over a year now. There have been posts on the forum saying that their baked GPU was still working after a few years.

I am not suggesting the OP to not get a new GPU, but if the OP was already concerned about investing too much money on an old computer, then the price of a GPU might just be too much.

I was just saying there are low cost options if the GPU was having issues.
Coincidentally, I just got the chance to try a GPU bake this week.

This was for a Mac Pro though and I already had another better video card, but I did the bake on a nearly-dead Quadro FX 4500 anyway just for fun. Before the bake I would get the 2D boot screen but it would never load the OS and then would cause a kernel panic. The 2D boot screen was clear though.

After the bake, I could consistently boot into El Capitan, but both the 2D boot screen and El Capitan had snowy artifacts. (Screengrabs were perfect, but output on screen was snowy.) So, the bake stabilized the GPU, but appears to have damaged the memory (or something else after the GPU). At first I thought its was because I didn't have proper thermal pads on the memory, so I invested in some thermal pads but that didn't solve the problem.

So, it was ultimately a failure, but it was a low cost one, something like US$8 for the thermal pads with tons left over. However, even as a failure, it could be considered a success for an emergency. Say I had something critical and not yet backed up on there, it was usable enough to navigate around the OS and access the drive, etc. in case I wanted to pull some data off.

Hello guys
I need your help 🙌... I have an APPLE iMAC desktop computer, here are technical specifications: MacOS version High Sierra 21,5- inch, Mid 2010 Processor: 3.06 GHz Intel Core i3 Memory 6 GB 1333 MHz DDR3 Graphics ATI Radeon HD 4670 256 MB.
A few hours ago I proceeded to a deletion of my data in the hard disk (in order to sell it), when starting I get the folder image with question mark as described in the link below If your Mac starts with a question mark.
I followed the instructions of the link, but once the recovery of macOS is done via the Internet, after about twenty minutes, my Laptop remains stuck on the screen with the apple, even after 2 hours, nothing happens. I need your help.
What do I have to do to reinstall the macOS again?
Thanks in advance for your quick feedback.

If recovery fails, you can always reinstall MacOS using the USB installer method. You will have to create the USB installer from another Mac, though.

I would just turn off the machine and try the recovery method for a several time before switching to another method.

Hello @Nguyen Duc Hieu

Now everything is back to normal. I have used my ethernet cable in order to complete my reinstallation.

Hi Everyone!

I recently pulled out of the dust a 27" iMac mid 2010 2.8 ghz intel core i5 1tb, 4gb ram.

And i was wondering if you consider it worth the extra $400 to upgrade it to larger ram and SSD, or if i should just sell it for that same amount.

Hi Andrea!

Performance wise, that will be more than adequate for most users with another 8 GB RAM (or total 12 GB), plus SSD. However, the problem with this particular model is that I believe it has the Radeon 5750 video card, which prevents it from being updated past 10.13 High Sierra. 10.13 is quite decent, but sooner rather than later it will lose browser updates.

If you do decide to update it, one issue is you also have to be careful who you get to install the SSD. There are a number of ways to do it.

1. Install an SSD with dedicated heat sensor adapter. This works well but costs the most.
2. Install an SSD with an optical drive sensor. Supposedly this also works well and is much less expensive.
3. Install an SSD with no sensor at all. A lot of small shops do this but this is definitely not recommended. If you install it without a sensor, the default for the Mac is to run the fan at maximum, which is quite loud and irritating. You have to install fan control software to keep the fan speeds down, but it's a poor workaround IMO.

I have a 2010 i7 model and had also contemplated the upgrade, but I ended up using it as a monitor instead. I have a dual iMac setup, with a 2017 27" Core i5 Retina as the primary machine, and the 2010 27" Core i7 non-Retina used in Target Display Mode as a monitor.

And i was wondering if you consider it worth the extra $400 to upgrade it to larger ram and SSD, or if i should just sell it for that same amount.

Many options to consider, but I would recommend some simple and non-expensive upgrades, suppose the display is still good (bright and clear, no smoke, no dead pixel, no yellowish stain, etc....)

1. Use it at a monitor => cost zero
2. Add some RAMs => 2x4GB second hand SODIMM cost around 20$. If you can get 2x2GB for free (removed from some old/dead laptop, etc.), that would be enough too.
3. With 8GB RAM, even the HDD can keep the machine run smooth for light jobs (Word processing, small worksheet, online education & meeting, entertainment)
=> If you can purchase (and want to have) a 27" 2K monitor for around 400$, why don't you just keep the iMac?

Maxed out upgrade calculation:
Core i7-870 => 40$ (double number of cores and threads comparing with the core i5)
32GB Ram => 120$
GPU => 240$ (WX7100)
SSD => 40$~200$ depending on capacity. Don't need to replace the 1tb, just add the SSD. Use the 1tb for 2nd OS disk and file storage.

But anyway, upgrading should be limited to "experimental projects"

For a serious working instrument, I'd just sell the iMac and buy a new one + Apple care.

I have to agree with the others. I have a late 2009 i7 2.8ghz with 2tb and the RAM is upgraded to 12 GB. It is on High Sierra and can't go further without using a patch. I expect security updates will likely stop when Big Sur is released soon. The machine is slow, but other than taking a while to get the HDD moving from sleep and a slow reboot it works reasonably well for web and mail. I even have Parallels on it to run Windows 10 for one program. It works, but is painfully slow at times.

I know upgrading to an SSD would speed things up a good bit, but I decided it was time to replace the machine. I might try an upgrade at some point just as a project, but more than likely I am either just going to use it as a monitor or perhaps erase all of the data and use it to stream content when exercising, maybe using a Linux distro rather than Mac OS.

It's an inexpensive enough upgrade to do it yourself if you want a project, but for $400 it sounds like you would be paying someone else to do it and I don't think I would personally do it at that point. But YMMV.

The problem with the 2010 with Radeon 5750 is that it can’t go past High Sierra even with the patch. It’s unusable with later patched OS versions.

The 2009 can go past High Sierra with the patch. I’m using the patch to run Catalina on a 2008 MacBook and a 2009 MacBook Pro. There are a few minor glitches here and there but overall the OS experience is very good. The main problem is those old laptops are slow. My 2010 iMac far, far faster, but unfortunately is stuck on High Sierra.

The sad irony of this is that my 2010 is actually a replacement for a defective 2009. At that time I thought that was a bonus, but now not so much.

I replaced the original disk with an SSD in my mid 2010 but am not happy with the performance. Is this normal? Is there anything I can do to increase performance?

If "performance" means the indicators in those tests, then there is nothing else you can do.
If your SSD is a slow one, change to a certified faster one may help, but not much. Quite an insignificant improvement in actual use.

If the GPU is the main obstacle, then maybe it's time to upgrade it.
I'm awaiting my order of a core i7-870 and a WX4150 to upgrade my iMac mid 2010.
If WX4150 fail, I'll order a K3100M to try.
Kind of wasting money, because the original GPU is serving my use well enough, but anyway, I really want to see my iMac running at its top specs.

Your 2010 iMac can only do SATA 2 speeds so you're not going to get the full speeds of that SATA 3 SSD. Do you actually feel the computer is slow? Or were you just expecting to see higher benchmarked speeds?

Both. I feel it is a little slow. That's why I installed SSD. It's a 2.93 Core I7 32GB RAM.
I also did a high Sierra clean install.

Is there any other upgrades I can to to make it faster?

You can upgrade the GPU, that likely won't improve normal day to day usability but certain apps and games will run better of course. Other than that, you're maxed out. I found my 2010 i7 iMac with similar specs to yours extremely usable, until it died.

Yes I have been thinking about GPU. Works with heavy image processing so a better GPU can certainly be a good idea. I've read a lot about GPU upgrades lately but am a bit confused. What is the best GPU solution?

WX7100, the equivalent of RX580 8GB in PC
Cost about 250$.
Another 50$~100$ to get the 3-pipe GP heatsink, if you don't have it already.
