macOS Mojave Run On My Mid 2010 MBP?

The reason Apple is moving toward non-replaceable RAM and storage is that removing the sockets these devices sit in, and soldering the components directly to the board, improves reliability dramatically.

If they can keep the costs of Drives and RAM reasonable, you get a MUCH more reliable machine at about the same price-point as before. You just have to get used to the idea that you need to buy a little larger than you used to, to allow for some growth, because you cannot swap Internal drives later.

If your needs change so dramatically that you need a computer with much more RAM or much more Internal storage, you can sell the old computer and buy a different one that meets those needs, or hand the old one off to an employee with more modest needs.

Switching to Windows over this issue is really, "cutting off your nose to spite your face."

iMacs have never had upgradeable hard drives.

Certainly not true. Just one example: https://eshop.macsales.com/upgrades/imac-retina-4k-21-5-inch-late-2015-3.3-ghz/i nternal-drives

It's not an easy job, but it can be done.

It is most definitely not true. A trained technician with the right tools and replacement parts can repair virtually any internal component. That does not make all those components upgradeable. Of any such internal components, iMac hard drives are one of the least upgradeable. It is only possible because OWC has reverse-engineered the temperature sensor and included the hack in their adapter cable. I have replaced the hard drive in an iMac and I would never recommend that anyone else attempt it.

It’s not an easy job, or without risk to damage the screen, but the videos I’ve seen for replacing HDs don’t include anything about modified temperature sensors or cables.

Then in theory my 17 inch should be able to run it as I have checked both graphic cards are the same for my 13 inch pro and my 17 inch pro yet the 17 inch pro can not run it. While the 13 inch can I seem to be confused as to why because my 17 inch pro is a combination of a a Mac mini and 13 inch pro it has the same graphics card as the 13 inch with double the processor, memory and hard drive space as my Mac mini. Yet it seems to be that something is off between the 2012 13 inch and the 2011 17 inch that I am not seeing.

Perhaps you aren't looking at the right videos. For example, your first link was an upgrade kit for a 2015 iMac or newer. That video is for a 2013 iMac. If you look at the upgrade kit for a 2011 iMac similar to the one Nanchatte Technojunkie was referring to, you will see that it does include a special OWC thermal sensor cable. I don't know. Perhaps the 21.5" iMacs don't need the sensor cable. If anything, I'm even less likely to recommend that repair now.

OWC HDD Installation tools & SMC Compatibility Solution For 2011 iMac

Right now and probably next year we won’t but eventually the 17inch pros will become like the 06 MacBooks they will continue to ask you for updates even though you can not. Along with some of us were using the 17 inch for development purposes for the fact of portable screen space. I know the new machines have better pixel counts but at the end of the day there is only so much you can fit on a 15inch screen.

Not sure about anyone else but all 1500 machines from my company are 2010-2011 windows machines the only thing we typically did along with my MacBook pro is upgrade the memory in them and hard drives.

etresoft stated that iMac HDDs have never been uogradeable.

I beg to differ. Every single iMac I bought for my company 2007-2011 models

I have updated to either a 256 or a 512GB SSD.

The earlier machines required the HDD to be replaced but the later machines have an extra SATA port just for SSDs.

I have a couple of old 2006(?) white plastic 24” models with gorgeous screens and they run as keynote noticeboards. They have been updated to 128GB SSDs

****, I have a 17” lampshade iMac that has run the welcome animation on a loop in the lobby for over 10 years. I updated that to a 32Gb PATA SSD.

My main machines are 27” 2011 i7 3.4GHz with 32GB RAM and have run flawlessly with after market 512GB SSDs added in the cavity provided.

So I have no idea where you’re getting this idea that iMac HDDs are not upgradeable.

As I mentioned I will have to move back to Windows as soon as the Macs stop supporting the latest software.

Unless Apple reverse their policy on allowing after market upgrades without having to melt glue just to open the bloody machines.

(Not going to pay $5000 for a Mac “pro”)

If changing the Graphic Card, which Graphic Cards will support my old MBP?

MacBook Pros don't have graphics cards. The graphics chips are soldered on to the logic boards.

And, are you supporting the idea that Apple shouldn't advance the hardware and software in their new models because they need to continue legacy support for 8 year old Mac models?

Because I’ve done it and I know Apple. Apple sells consumer machines. Apple doesn’t seriously market or sell machines to businesses. A few businesses might spend 3X the price to use Macs, but that is unusual. If you have an IT support staff, then you can always perform any upgrades you want. You are only limited to the skills, tools, and resources that your company can provide.

But you are doing a disservice to 95% of the people in this forum by saying iMac hard drives are upgradeable. They are not. By that logic, you could just as easily say that the CPUs, GPUs, I/O ports, and logic boards are upgradeable too.

There is absolutely no internal component in an iMac that can be replaced without significant risk of damage, even by a trained technician.

NO.

eGPU support announced now will support only ThunderBolt-3 ports, as it says plainly on the Apple web site:

Highlights Compatible with Mac with Thunderbolt 3 ports

Blackmagic eGPU - Apple

That box costs US$700. If you have that kind of money, a more modern Mac with a retina display should be considered.

The last operating system version that I remember being faster, more stable, and less buggy than the one that came before it was 10.8 "Mountain Lion". And even then, I'm only comparing that that version 10.8 "Lion". People wax nostalgic about how great 10.6 was, but that was a long time ago.
