Re: I ask for help!
I have a tablet and I see all the wifi networks around here.
In Mac Mini settings it gets searching for networks and shows nothing.
I do not know why this. It never was like that.
You have technical knowledge or have already had a similar problem or someone you know has already presented this same situation.
I personally have not encountered this specific behaviour.
The first idea that comes to mind is to run “Wireless Diagnostics” that is located (in macOS Big Sur) at
/System/Library/CoreServices/Applications. It will take a while to run. If it prompts to monitor, you can just tell it continue as is (not monitor).
It should give you what it found, hoping it finds something useful.
Here’s what my run suggested.
What would be interesting is to see if the computer can detect any defective components using the Diagnostics tool.
To do so, you will need to power off the MacMini, then power it on while pressing the “D” button on the keyboard. Keep pressing the button until you see the Apple logo or “Starting Internet Recovery.” If it asks you to choose a network, let’s see if any networks are found (double test); if it doesn’t find a network, you will need to run an Ethernet cable.
Can my mini MAC upgrade how much memory?
According to
MacTracker, if you have a mid-2011 MacMini, Apple supported up to 8 GB of memory on that device.
The documentation on adding memory to the MacMini can be found at:

Yes you can. This was not a supported upgrade by Apple however.
The Mac mini I have felt that it is a bit hot, how can I improve it.
It has a notebook base to cool.
Because he does not worry that I'm not running any program.
During system installing a little heats.
Do you know what it is?
It’s hard to say, but it could be several things that are causing your computer to heat up, including:
- Dust in the fan(s), or elsewhere in the system (the easiest)
- The mechanical hard drive working extra hard
- The thermal pad/paste on the CPU and GPU might have dried up.
Of course, some of these are not for the faint of heart. Assess your own level of comfort, based on your own knowledge.
It can be difficult to disassemble some Apple devices, so before doing so make sure you’re comfortable. I personally would not replace the thermal paste on an Apple device, because I’m not comfortable doing it on those devices.
