Changing processor in Late 2012 Mac Mini

If you want a new processor because your Mini is slow, there are more effective options that will make a greater difference if your Mini current has a mechanical hard drive. Most Macs of that era that are considered slow by their users are slow becasue of their mechanical hard drives, not their processors. Example of two options to deal withtn eh mech drive:

—Requires opening the computer: I have a 2012 Macbook Pro with the same i5 processor and virtually identical benchmarks as your 2012 Mini i5:

It came with a slow 5400rpm hard drive whose max data transfer rates were about 70MB/sec even when new. After a couple of years of struggle, I replaced the HDD with an inexpensive internal SSD. Now the transfer rates are ~500MBsec and the computer still gives plenty of satisfying speed, and remains my travel Mac today, over 11 years after its purchase.

—The "non-invasive option: You can attach a USB3 SSD external drive, clone your current internal drive to it, and set the external as the boot volume. The cheapest incarnation of that at-home conversion will do 400MB/sec, still plenty-fast compared to a 2012 mech drive.

Information on the external boot volume option is here:

thanks! And my Mac Runs 13.6. Also I can’t buy a motherboard from a i7 Mac 2012 and just put it in my i5 Mac 2012?

That Mac can run macOS 10.15, and is not supported on macOS 13.

Apple doesn’t sell Mac mini 2012 parts to end users.

Some third parties can and usually do offer parts and upgrades, but with the usual caveats.

I’d look at some of the available teardown videos, and see if the project is something you want to consider, too.

You can buy a 2012 Mac mini 2.3GHz i7 for $105 or a 2.6GHz i7 Max for $159

If I may ask, why are you wanting to invest money on a 2012 Mac mini instead of wanting to buy a new or newer Mac mini?

What’s your goal for this current or for this potential upgraded Mac?

An RPi or a Pine64 board might be a better investment, if you are looking for computing flexibility. These won’t run macOS of course, but quite effective at many tasks, and with community support.

Mac mini late 2012 tops out at macOS 10.15 as well, so not too far back, but still well back enough from current macOS to add to the effort involved. The most recent three versions have the deepest support. This Mac mini is also Intel x86-64, which is the previous architecture.

That mini will also run FreeBSD and some other OS choices, if you are interested in learning about that.

You’ll certainly learn about disassembly and reassembly here, following your current plan.
