[mac Big Sur]If you want to record sound from your PC, use BlackHole.

I tried to install Soundflower on my PC (OS: Big Sur) to record the sound coming out of my M1 model macbook, but
I tried to install Soundflower on my PC (OS: Big Sur) to record the sound coming out of my M1 model mac, but I got a message that “Soundflower.pkg” cannot be opened because the developer has not been confirmed.
After some research on Google, I found that
After some Googling, I found out that the solution is to go to [Settings] -> [Security & Privacy], allow downloads, and click [Open As].
I’m sure everyone (including me) has found a solution like this.

I’m not sure if you’ve tried to install Soundflower on your macbook.

If you can’t, you can’t, so install BlackHole instead of Soundflower.

Steps to install BlackHole as a replacement for Soundflower

First, proceed to the official website.

BlackHole official website
From the top, enter [email address], [first name], and [last name], then click [Subscribe for Free Mac Download].

If your email address is entered correctly, you will soon receive an email from BlackHole with a download link, so click on the download link.

Open the link in the email to open the BlackHole download page, and click on the “BlackHole 16ch v0.2.9” to start downloading.

Click on the downloaded pkg file to open the installation window, and follow the steps in the installer to install the software.
After the installation is complete, you will be asked if you want to put the installer in the trash, but you don’t need it anymore, so throw it away.

Where is it? To open the installed BlackHole

I tried to start up the installed BlackHole, but I couldn’t find it when I looked into [Applications].
The name of the application is “Audio MIDI Settings”.
If you want to open it from the Dock application, go to [Applications] -> [Launchpad] -> [Other] -> [Audio MIDI Settings].
If you want to open it from Finder, you can go to [Finder] -> [Applications] -> [Utilities] -> [Audio MIDI Settings].

How to set up BlackHole to record sound from your macbook

Now that it is installed, let’s configure it.

When you open Audio MIDI Settings, a window like the one above will open. Click the [+] mark in the lower left corner and select [Create Multiple Output Devices].

Check the “BlackHole 16ch” checkbox.

Right-click on the [Multiple Output Devices] you just created to open the window shown above, and click [Use this sound output device].
You can now close the Audio MIDI Settings window.

Set the microphone to BlackHole in QuickTime Player.

Right-click on QuickTime Player and open [New Audio Recording].

Click on the red record button to the right to select the microphone you want to use.

If you can’t record, please reboot after installation.

Try playing sound from your MacBook on Youtube, itunes, or anything else.
If the volume gauge of the QuickTime audio recording swings, you have succeeded.
If not, you may need to restart your computer.
Restarting the computer may help if the recording doesn’t work right after installing BlackHole or after changing Audio MIDI settings.
If the volume gauge is not moving, even if you can click the record button, no sound will be recorded.

When using BlackHole, you cannot use the function keys to adjust the volume.

When the microphone is set to [BlackHole 16ch], you will not be able to adjust the volume or mute the microphone using the function keys.

If you want to adjust the volume using the keyboard such as [F10], [F11], [F12], etc., such as when you want to check the recorded audio file, please go to [System Preferences] -> [Sound] and change it back to the built-in speaker of your macbook.

What to do if you hear a blurry sound when you play back a recorded audio file?

This is a little off topic, but for example, when using Google Translate on your computer, you can only select a female voice, but if you want to have it read out loud in a male voice, you can use Siri instead.
How to use Siri to read out a sentence in a male voice
You can also use BlackHole to save the voice as an audio file, which you can then use to create a narration for Youtube.
End of story
When you successfully record and play back the audio file, you may find that the sound is blurred, or as if it was recorded in a large room.
I don’t know how to describe it, but it’s not exactly howling.

If you feel the above indescribable discomfort when you play the resulting audio file, try changing the recording quality of the audio recording in QuickTime Player from [High] to [Highest].
I tried various things in the Audio MIDI settings under [Speaker Configuration], but no matter what I did, it didn’t improve, but just changing it to [Highest] usually did.

Summary of using BlackHole with Big Sur

I used BlackHole to record the sound of my PC with the result that I could not install Soundflower with Big Sur.
I had to reboot to get it to work (or was that just me?). But I was able to record without any problems.
I’m sure many people are in the process of switching to a macbook with M1 chip, so I hope this will be useful for those who have no choice but to switch to BlackHole.








How to use a Switch controller to control minecraft on mac. Setting public [Joystick Mapper].

I installed the mac version of minecraft, but… keyboard control is too difficult!
If you’re not used to playing computer games, it’s impossible to play the PC version of minecraft with a keyboard.
If you’ve installed minecraft on your mac without realizing it, you’re probably regretting it.
Don’t worry.
Use the Pro Controller (or Joy-Cons) for your Switch.

You can use a home console controller to control minecraft on your mac!
Please explain it in a video! If you want to learn how to do this, please go to

The following article will help you to record a video of playing with a pro-controller from a third person’s point of view, and watch a replay video.

Connecting the Switch controller to the mac via Bluetooth

First, let’s connect the controller to the mac via Bluetooth. It’s easy.
Setting up the controller
There is a small button at the top of the controller (near the charging port), press and hold it.
The way to do this will differ depending on the type of controller, so check it out as you go.
Bluetooth settings on the mac
Go to [System Preferences] > [Bluetooth] and click [Turn Bluetooth On].
If the controller is ready, the name of the controller connected via Bluetooth will appear in the [Device] field, and click on it.
If successful, [Connected] will be displayed.

Connected successfully! Okay, let’s get started with minecraft… but it doesn’t work…

That’s right. The world is not so easy.
You can’t control your mac with the controller just by connecting it via Bluetooth.
Let’s continue with the explanation.

Using mapping software to link controller buttons and keyboard [Joystick Mapper

The Bluetooth connection is successful, so it seems like it should work, but unfortunately it doesn’t.
In order to link the controller’s buttons to the keyboard, you will need something called mapping software.
In this case, we will use a software called “Joystick Mapper”.
Joystick Mapper

Unfortunately, there is a fee.
However, we can’t turn our backs on it to improve the usability.
Do you want to play minecraft comfortably with a controller on your mac?
Then buy it. Money is the answer.
In fact, as an amateur who played minecraft with a pro controller after using Joystick Mapper and mapping the settings as described below, I found that it was about 80% operability with the controller compared to 20% operability with the keyboard.
For more details on how to set up Joystick Mapper, please refer to “Joystick Mapper: How to Use a Mac with Joystick or Pro Controller”.
Anyway, it’s totally different. It’s a totally different experience.


How to use the Joystick Mapper to control a mac with a joystick or pro controller.

I’ve given it a lot of thought, and I’ll post the settings that I think are best at this point.
After connecting your mac to the controller via Bluetooth, use Joystick Mapper to configure the settings as shown in the table below.
Please do not change the control settings in minecraft.

In the above figure, after clicking [scan], press one button on the controller, and the button information (Hat, #0, Down, etc.) will be detected automatically.
Change the [keyboard key] part and the [Q] part as shown in the table below.
In this setting, buttons that are not used by the controller are not registered.
[(scan) / controller control / automatic / automatic / change as needed / change (minecraft movement) ] The view will be as shown above.

Differences between minecraft for nintendo switch and the controls

If you set it up in Joystick Mapper, 80% of the operations will be the same.
However, there will be some discomfort (about 20%).
The following is an explanation of the 20% of discomfort.
Cursor operations in the menu screen and item screen
You use the right stick to control the cursor in the menu screen and item screen.
The left stick is unresponsive.
Deciding and Returning in Menu and Item Screens
To make a decision, use [ZR (Main click)] instead of the [A] button.
To return to the play screen from the menu screen, or to close the item screen, press [Y (Escape)] instead of [B].

Once you get used to this, you will be able to play minecraft quite comfortably.
Now, use the Switch controller and have a fun minecraft life on your mac!



How to take hand-held videos|How to fix your phone at any angle and shoot from your eyes

This course explains how to film your hands from your own perspective while having both hands free, such as working on a desk, streaming sound games, cooking videos, etc.
You can shoot from above, hold your phone at any angle, or master eye-level shooting.
There is no trick to mastering it.
Just buy one. Money is the answer.

How to shoot without shaking with a tablet arm.

Trying to shoot with a phone in your hand will never work for eye-level shooting.
If you want to shoot good hand-held video, a tablet (monitor) arm is a must.


I bought the following product, and I recommend it because it doesn’t wobble at all.

I bought the following product, and I recommend it because it doesn’t wobble at all. The cheap ones with a squishy bendable arm have a weak grip, or the arm is too weak to withstand the weight of the phone.
I recommend you to buy an arm that is about the price of the product link above, as it can hold your phone firmly.
If you are considering buying an arm for handheld photography, you might want to buy one with a ring light.
If you are considering buying an arm for handheld photography, you might want to buy one with a ring light. .
I bought one with a ring light, which was mainly for the purpose of “watching my iPad while lying down! I’m just using it to take handheld photos of products whose main purpose is “I can look at my iPad while lying down!
If you’re going to shoot hand-held, it’s definitely better to have lighting than not, so I’d consider buying one with a solid arm and a ring light.
There is also a similar product, a tripod type stand, but if you are filming work on a table, the legs of the tripod will show up in the video if you are not careful, so you need to be careful when choosing one.

Actual video shot using the tablet arm

I tried writing with the tablet arm. The picture is taken from directly above.

Whether my handwriting is good or not, the video itself is well shot without blurring.
It is possible to film while looking directly at the paper and pen with your eyes.
As I mentioned earlier, the video seems a little dark, so an arm with a ring light would be better.
In this video, I gripped the arm on the side of the table and brought the phone to my eye level to hold it in place.
You can use the arm on the side or on top of the table as long as you can grip it.
If you want to shoot a wider area like a cooking video, you can fix the phone on a cupboard or something and shoot from above.

How to adjust the angle by moving the movable part of the tablet stand

The fixing method is quite simple.


Place the base of the tablet stand on the edge of the table, and turn the bottom screw to fix it in place.
The part of the stand that directly touches the table is covered with rubber, so it won’t scratch the table.


It is now fixed as shown in the photo above.
This tablet arm has four joints, so you can bend and rotate it to bring the head part to the position you want.
So, by setting the arm to the side, you can bring the camera right above you while dodging your hands.


I set up the tablet arm on the side and moved the phone right above the keyboard.


In this way, you can shoot videos using both hands from your own perspective.
Situations where using the arm stand is useful
Cooking videos
Drawing videos
Writing videos
Typing speed videos
Videos on Sound Games (Bandori, etc.)
Clay animation videos

A remote shutter to remotely control the shooting button is useful.

If you have adjusted your phone with the arm so that it is at your eye level, but when you tap the shoot button, it would be uncomfortable to have your phone out of alignment, so a remote shutter for your phone would be useful.
I bought this one.

You can usually buy them at 100-yen stores these days.
If you connect it to your phone via Bluetooth, you can tap the button on your phone remotely without having to tap it directly.

If you want to shoot with your hands, you’ll need an arm system that can hold your phone.

When I first wrote this article, I was recommending a tablet arm, but I think an arm with a ring light would be better if the main focus is on “photography”.
It’s not a tripod type, but a type that can be fixed to a table, etc.
If you are considering using an arm with a ring light for live online shopping or makeup videos, I recommend you to use it.

[Fire TV Stick Initial Settings] Restarting the device will solve the problem of no sound or no display.

fire tvを挿す

When you connect your fire tv stick to a TV for the first time, you may find that the screen does not show up or the sound does not come out.
Here is a brief explanation of how I solved the problem of no screen and no sound.

If nothing appears on the TV, unplug it once.

If nothing appears after a while after connecting to the TV, try unplugging the power supply plug once.

fire tv stickを接続してもテレビに何も表示されない時は一度電源プラグを抜く

As you can see in the picture, there is a USB cable extending from the main body of the fire stick that plugs into the wall socket, so unplug it, wait about 10 seconds, and plug it back in.
Unplug it, wait for about 10 seconds, and plug it back in. If you see the “amazon” logo, you’ve succeeded.
I was happy that it worked, but then the TV went dark again.

If unplugging and plugging in the power supply doesn’t work, move the HDMI port slightly.

If the problem is not solved by unplugging the power plug, it may be a physical problem with the connection between the TV and the fire stick.
Unplug the fire stick from the TV and plug it back in.
Also, if you move the connection part up and down, left and right, back and forth, etc., just a little bit (just a little bit so as not to break it), it will connect properly and you will be able to see it on the TV.
Although the video output stumbled during the initial connection, I have been using it for about two years now and have not had any problems with it not working again.


If you connect the TV and fire tv stick itself directly to the TV, it is easy to break when people or objects bump into it, so you can use the extension cable that comes with it.

If there is no sound, reboot the fire stick.

If things are going well, you can hear the “beep” sound when you move the cursor on the menu screen.
In my case, however, I was so busy with the initial setup that I didn’t notice the lack of sound until I was actually watching a movie.
If you see the image but no sound, reboot the Firestick.
Use the remote control to go to [Home], [Settings], [Device], and then go to [Reboot] to reboot the fire stick itself.
You will be able to hear the sound after the reboot.

Selecting the dolby digital output didn’t produce sound after all.

There was no sound, and when I checked various sites, I found something about [dolby digital output].
I’m sure you can get sound by rebooting, but in case you can’t fix it by rebooting, here’s another way to fix it (I couldn’t fix it this way)
Go to Home→Settings→Display and Sound→Audio
Using the same remote control, go to [Home] -> [Settings] -> [Display & Sound] -> [Audio].


There is a “dolby digital out” option, so you can select that (although I didn’t).
You will get sound one way or the other.

Initial settings for the fire tv stick (just in case)

If you can see the image on the TV and hear the sound, you are probably done with the initial setup, but just in case, here is the explanation.

fire tv stickの初期設定(念のために)

There is a language selection, choose Japanese.

When you get to the screen to connect to the network, select the wi-fi that you use at home.

Enter the wi-fi password (it’s written on the back of the router or something)

Set the functional restrictions and download the necessary applications.
You can change these settings later, and use functional restrictions as needed.

Can’t I control the volume with the remote control of the Fire Stick?

As it turns out, you can’t adjust the volume with the old fire tv stick (1st generation) remote.
There are products that can adjust the volume for first generation remotes, but they cost over 10,000 yen, so I don’t recommend them at all.
The newest fire tv stick is only about 5,000 yen and has a volume control function on the remote.
Adjusting the volume on the TV remote is a pain in the ass! I want to do it with the fire tv stick remote! If you want to use the fire stick remote control, you should buy a new model.


If you are confused about video apps, Amazon Prime Video is fine for now.

There are many video streaming services such as Netflix, hulu, and Amapla, but if you want to use the download function and watch them on your car navigation system, Amazon Prime is the way to go.
With Netflix and hulu, you can’t watch downloaded movies in the car due to the hdcp (copy protection).
However, if you use Amazon Prime Video, you can watch videos in the car without wi-fi.
The free trial period is set at 30 days, so if you want to stop using it, you can just cancel it.
This is the solution to the problem I had when I initially set up my fire tv stick.
