Hi guys and welcome to 123myIT. In this video, we will show you all the Mac M1 Start-up Modes. These are helpful if you need to troubleshoot or work on your Mac for any reason.

This video will show you how to open Startup Options. Start the Mac with Diagnostics, Recovery and Safe Mode. Also show you how to set a default Startup Volume.

Lets get started. I am using a MacBook Pro M1 computer. First step is to shut down the Mac.

Start-up Modes

Once your Mac is shutdown to get into Startup Options press and hold the power button until you see the Apple logo with Continue holding for Startup Options menu. When you see the Options cog you can let go of the power button. This is the Startup Options menu and you can do things like select bootable disks.

Diagnostics modes and other modes

Diagnostics Mode

To get into Diagnostics Mode we want to press and hold Command and D keys until your Mac Restarts and you will see the Diagnostics Menu load. Now you might need to connect the Mac to your WIFI to start the diagnostics. Once you have connected to WIFI the Diagnostics will download and you can use the Diagnostics to see if you have a hardware problem with your Mac.

Just click Run Offline and the Mac will check all your hardware to see if its ok. I get an error with my power adapter because its not plugged in. If you click get started it will show you a list of error codes. So if you have faulty hardware you can contact Apple for help.

If I plug my cable back in and run the test again I don’t get any error codes. This means that the Mac hardware is fine and working correctly.

Start-up Disks

If you want to check startup disk, reinstall MacOS, restore from backup or change security settings go into Recovery mode by pressing the Options Cog. So in Recovery menu you have Restore from Time Machine. Reinstall Mac OS. Disk Utility and Browse Apple support.

Safe Mode allows you to Flush user cashes and disable third-party extensions. TO get into Safe Mode go back into Startup Menu and press and hold the Shift key. Then click continue in Safe Mode underneath it. You Mac will restart and then you should be able to see the top right hand menu. Simply logon and your Mac will be in safe mode.

If you want to set a default startup disk go back into the Startup Menu and press and hold the Option key. Under the Disks it will show Always Use option. This allows you to set the default Startup disk. Helpful if you have multiple disks.

Fix Broken Bricked Mac with Restore Revive

Hi guys and welcome to 123myIT. In this video, we will show you how to fix a bricked mac or broken MacBook with revive or restore.

Guys if you are like me and you have bricked your new Mac M1 or other MacBook’s then you can try to do a restore or revive process to get it working again. You might be getting the black screen with exclamation mark and the restore URL on it. This video will show you how to fix it.

Restore Revive Bricked Mac

To do a restore or revive you will need another Mac or MacBook. This Mac will push the restore to software to the broken Mac. IF you are like me and did not have a second Mac try borrowing one from a friend or you might have to go to an Apple store.

Let us get started. I am using two MacBook Pro M1 computers. You need to plug the power cable into the working MacBook on the right USB C port. In addition, plug the second USB C cable from the second MacBook to the left port. Then plug the cable from the left port into the left port of the broken Mac. Here’s a picture you might find helpful for the different Macs.

Apple Configurator

Next up download and app called Apple Configurator 2 from the App Store. Go ahead and open Apple configurator 2. Once that is done, you will need to put the MacBook in DFU mode. This can be a bit tricky.

You need to:

1. Press the power button.

2. While holding down the power button, at the same time press all three of the following keys for about 10 seconds:

The right Shift key

The left Option key

The left Control key

Other things to know are revive will revive the firmware and reinstall the latest version of recoveryOS.

Restore Firmware

Restore will restore the firmware, erase all data, and reinstall the latest version of recoveryOS and MacOS. Bricked Mac.

Therefore, if you do it wrong it will come up like this. It has the padlock there and you cannot revive or restore this Mac. Ok so let try again. Press and hold the Power button then press and hold the Right shift, Left Option and Control keys.

3. After 10 seconds, immediately release the three keys but continue to hold down the power button until it appears in Apple Configurator 2.

Your Mac in DFU mode – Bricked Mac

Awesome, you have now just put your Mac in DFU mode. Just like an iPhone. Now depending on how you broke your Mac you will need the Revive option or the restore option. To find these menus right click on the DFU sign on the first Mac and go to Advanced. Under Advanced you will have the revive option otherwise I will use the restore option.

Ok the restore revive will start and may take some time so go ahead and hit the like button and subscribe guys!

Cool, if everything goes well then you should see the DFU replaced with a padlock. Moreover, your broken Mac should now be fixed. You can go ahead and setup your Mac again.

MacBook Air M1 vs MacBook Pro M1

Hi Guys and welcome to 123myIT. In this video, we will show you comparison between the Apple MacBook Air M1 vs MacBook Pro M1.

Before I start I already have done a video on the MacBook Air and Pro M1 model and if you want to see that video I will put a link in the top of the video and the description below.

Dirsplay – MacBook Air M1 vs MacBook Pro M1

Display Brightness compare MacBook Air M1 vs MacBook Pro M1
Compare display brightness between MacBook Air M1 and MacBook Pro M1

Both the MacBook Air and Pro M1 come with a 13.3-inch LED Backlit Retina Display with IPS technology. They both a resolution of 2560 x 1600 and 227 pixel per inch, but the Air has 400 nits of brightness and the Pro has 500 nits of brightness. This means you should be able to see the slightly brighter display on the Pro on the right. Its not a massive difference but if you are looking buy the Air or Pro, its something you should consider. True Tone technology also adds a warmer more realistic colour to the display.

 In Terms of how heavy the MacBook Air and Pro are the Air is 2.8 pounds, which is lighter than the MacBook Pro on 3 pounds. The Dimensions are very simular for both models .16-.63 inches high on ther Air compared with .61 inches on the Pro and the are the same in width at 11.97 inches. When talking about portability the Air is slightly lighter but I don’t think the difference between 2.8 pounds and 3 pounds is noticeable.

Pricing – MacBook Air M1 vs MacBook Pro M1

Pricing for the MacBook Air M1 starts at $999 USD and the Pro is $300 more expensive on $1299. You can get the Air in three different colours Space Grey, Gold, Silver and the Pro in Silver and Space Grey. Storage options start at 256GB and go up to 2TB. Using the 256 GB model, I found the upgrade to 512 GB is probably worthwhile as I started having disk space issues after installing the Fortnite game, which requires about 90 GB. I started to wish I had the extra space. So consider this when buying the new MacBooks.


On the left side, you have two Thunderbolt, USB 4 ports. I would have like to see three as one could be taken up with a power adapter. There is No Ethernet, so this model is WIFI only. The USB 4 doubles as a display port so if you have a USB 4 to HDMI adapter you can plug in an external display.

On the right, you have a 3.5 Headphone Jack and there is no SD card reader so it does feel limited in terms of connectivity.


The design of the MacBook Air is different from the Pro as the palm rests slope down slightly at the front. This does make resting your palms on the MacBook Air slightly more comfortable. The Backlit Magic keyboard is a delight to type on and does not bend when pressing the keys. And there is very little flex on the keyboard too. The MacBook Pro does come with a touch bar which replaces the Function keys

Both models have Stereo speakers with Wide Stereo sound. However the MacBook Pro M1 has Stereo speakers with high dynamic range. They sit both side of the keyboard and are designed to point upwards towards your ears. The speakers have the best sound on any laptop I have heard so far. They are truly amazing. Here’s a comparison. Let me know what you think in the comments below.


The Force Touch trackpad is nice and wide on both models however the Trackpad is smaller on the MacBook Air but I never find myself missing a click or having to click twice.

Along the top, you will find an integrated 720p FaceTime HD camera with an indicator light. This is the same webcam on both models and there is no button to manually close the webcam. MacBook Air and Pro have Touch Id built into the power button. This allows you to set a finger print which negates the need for a password and you can log in to your Mac by tapping the power key.

Also included in the box is a 30 watt USB C power adapter for the MacBook Air and the Pro has a 61 watt adapter. You can expect to get up to 18 hours of battery life on the Air and up to 20 hours on the Pro, which is outstanding.


Cool, let us run the benchmarks. Starting the Cinebench software really works the MacBook Air hard. But you wont hear the fan spinning because there is none.

Heres the Cinebench multicore score for the Air which was 5324 this is not as good as the MacBook Pro score which was 7780.

Here is the Geekbench CPU single core score and the Mulitcore score.

Heres the GeekBench Compute score. As you can see the MacBook Pro did much better.

One other thing I noticed too. If you have two Macs and plug them in together via the USB C cable you only need to press the power button on one Mac and it starts up the other Mac Automatically.

You should buy the MacBook Air M1 if you want an affordable Apple Mac computer. It’s a powerful thin light laptop that runs Mac OS Big Sur. It’s very portable and it has amazing battery life and runs whisper silent as it doesn’t have a fac.

You should buy the MacBook Air M1 if you need even better performance and battery life. However it does have a loud fan which can be annoying. Which even model you decide to get I would defiantly recommend getting the 512GB storage model.
