Not according to EveryMac who are usually spot on with their info, including unsupported 'hacks', none of which are mentioned for this model. This model can simultaneously support the internal display at full native resolution and up to 4096x2304 on an external display in both extended desktop (second workspace) and video mirroring (internal display ...

It turned out that this error can be just ignored, because the user is properly created anyway.

I have an iMac 27 Late 2012 and I upgraded my SSD. The fusion drive is a misnomer - it's actually two drives. There is an PCIe SSD, probably about 128GB that attached to the logic board, then there's a 3.5" 1TB HDD. Technically, you could upgrade the PCIe blade SSD drive, but after some research, I found it wasn't really economical. All you need is a ...

The slot is proprietary, and it is not an M.2 or mSATA slot. I have seen no adapters on the market that will allow you to connect an ordinary SATA drive to the proprietary connector. Such an adapter would need to include an amount of electronics, as it is a completely different interface - i.e. it is not just a passive adapter. The only other supplier of ...

Most of the time will be spent separating the glue between the aluminum housing and the glass. Once you separate it, you can easily remove the glass and access to the drives are ...

I do not know which program you used to generate the output in the screenshot, but assuming it outputs the ordinary figures such as for example Activity Monitor or top would do - the reason for the seemingly erraneous swap usage is simply one of time. Imagine that a process on your Mac allocates 12 GB of RAM. The system hasn't got 12 GB of free RAM, so it ...

This is all anecdotal, tested using a sample size of 2, so barely counts as experiment... Restart the Mac, it's been up 12 days. That would be fine for a machine with a lot of RAM, but it's going to hit a low RAM machine harder. I'd say the simple solution would be to double the RAM. Two of the machines here are always on, the one with only 10GB RAM used ...
