In November 2020 Apple introduce its M1 system - on - a - buffalo chip that powers its latest generation of Macs . We ’ve already go out how these devices have seensignificant carrying out booststhanks to the newfangled central processor , but is that only thing to deal when choosing between them ?
We take a look at how the new chips change the path the Mac works and some thing you should be cognisant of before making your leverage .
We ’ve already write about how the M1 Macs liken to their predecessor , so if you just want a ecumenical guide on how the machines fare in terms of velocity , terms , compatibility , and the kind of modelling you could buy , then take a looking at these articles :
In this clause we ’ll concentrate more on technical change to some of the things you used to be capable to do on Intel Macs , such as booting from external drives , using Target Disk Mode , entering Recovery mode , computer hardware resets and other things that have exchange on the new M1 devices .
What’s different?
With Apple now name its own processors for Macs – sometimes referred to as Apple atomic number 14 – there are some insidious but key differences in how they interact with macOS when compared to Intel processors . This can mean that tried and tested spry fixes for computer hardware touch issues are no longer available to the drug user . We ’ll address some of the big differences below .
Entering Recovery on an M1 Mac
On Intel Macs if you want to use Recovery modality to wipe your Mac or reinstall macOS you enter the special modality by pressing and oblige Command + R during commencement up . Then when your Mac boots up you will have access to tools like Disk Utility .
On an M1 Mac the process is a piddling different .
There is also an additonal ‘ fallback recuperation mode ’ , that is detailed by Applehere . In this case you double iron the power push : first press it , give up , and then press and hold down the power push .
disengagement recovery modality accesses a second written matter of the recoveryOS on the SSD of the Macs with M1 Chip . The second written matter is there for resiliency , fit in to Apple .

Resetting the System Management Controller (SMC)
Traditionally on an Intel Mac , one direction to deal with any problems that arise with fans or power supplies is to reset the System Management Controller ( SMC ) . This is reach by switch off your Mac then restarting it , or using certain cardinal combinations , all of which are explained inhow to readjust the SMC on a Mac .
M1 Macs do n’t have a System Management Controller , so this route obviously no longer exists . All functions that were previously handled by the SMC are now incorporated into the M1 central processor .
you could still change some of these configurations . For lesson , you could use the Terminal creature pmset to switch rest modal value configurations .
If your M1 Mac has a job with its hardware you could attempt redact the computer in DFU mode and reinstall the microcode using Apple Configurator 2 and another Mac . Malus pumila runs through how to restore the microcode herehere .
Resetting the NVRAM
Another troubleshooting method acting that ’s missing from the M1 Macs is the ability to apply a keyboard combination to reset the NVRAM . This can be a useful locating for boot issues , audio problems or your Mac selecting the wrong blind resolution when start . We discusshow to reset the NVRAMseparately but we ’ll run through the fundamentals below .
On Intel Macs you moderate down theOption / Alt+Command+P+Rkeys when booting up the simple machine , but as far as we can tell there ’s no equivalent on M1 machines .
On M1 Macs the NVRAM still exist , but it work differently .
you may still take in and change scope with the concluding command NVRAM , but you may no longer completely reset the contents .
agree to written report , the M1 Chip essay the NVRAM when the calculator is started up from a complete shutdown . If it rule something wrong with the memory it will be reset mechanically .
An alternative is tostart the Mac in Recovery mode , start Terminal from the Tools carte and enter the command :
NVRAM -c

Restoring a Time Machine backup or using Disk Utility
Should your Mac experience knockout problems , you may require to restore a Time Machine accompaniment , snapshot relief or use the Disk Utility software to either fix or cancel the data on your hard drive .
While both are still usable on M1 and Intel Macs , the way you enter the option have changed . With Intel Macs , you hold downCommand+R(as describe above ) when booting the machine to start up with a recovery partition . From there you could choose which type of support or repair you want to use .
On the raw M1 Macs , the road is slightly different in that you power down the gimmick , then bid and have the mogul push button until you see a content about the startup options loading . Click theOptionsbutton , then you should see the same features as on the Intel equipment .
Choosing your boot volume
When going through the process above , you have the ability to take theUtilities > Startup Security Utilityoptions for more tools . In here , you would usually expect to find three option : Full security system , Medium SecurityandNo Security .
Apple discover the various tier in this way :
Full Security
“ Ensures that only your current oxygen , or signed operating system software presently swear by Apple , can run . This mode requires a mesh connection at package installment time . ”
Medium Security
“ Allows any interlingual rendition of signed operating system software ever trusted by Apple to run . ”
No security measure
“ Does not enforce any requirements on the bootable group O ”
M1 Macs only have the first two security tiers , presumptively as Apple tightens up the system against any vulnerability . In line to this , you’re able to no longer arrange a microcode password , although we ’re not certain why .
Booting from external drives
Another difference is power to boot from international drives . With the Intel Macs you ’d see the options in a section markedExternal Boot , but this is missing on the M1 Macs . That does n’t intend you ca n’t use external bang cause , just that the itinerary to them has been shift .
alternatively , power down your M1 Mac then contract and hold the power push button . This clip wait until after the startup option are to the full loaded before releasing the push . You ’ll see the available startup volume expose , so all you need to do is lumber in as an administrator and press the driveway you want to practice .
We have seen account of problem with Big Sur not being able-bodied to use extraneous thrill ride on either M1 or Intel Macs , but hopefully that issue has been resolved by the time you show this . If you ’re unsure how to lead off your Mac in this way be our guide onhow to install macOS on an outside driving force .
Using Safe Mode
If you reckon that software program you ’ve installed might be causing problems , a well elbow room to check is by rebooting in Safe Mode . you may do this on both types of Mac , but again you ’ll postulate to use unlike commands .
For Intel Macs , only reboot your Mac while holding down theShiftkey .
For M1 users , turn off your Mac and reboot it while harbor down the mogul key until you see the startup option have finished cargo .
Then , choose the internal disk , hold down theShiftkey and clickContinue in safe mode .

Using Apple Diagnostics mode
Another handy mode for troubleshooting is the Apple Diagnotics mode .
On Intel Macs , hold down theDkey when rebooting and you should mechanically infix the mode .
For M1 devices , hold down the business leader key when bring up until you see the startup options appear , then immediately pressCommand + Dto get in Apple Diagnostics mode .
Power naps and battery management
For MacBooks , it ’s important that you save barrage fire bursting charge and health to prolong not only how long you’re able to use the equipment on single charge but also to extend its living in universal .
Intel MacBooks have options for Power Naps and Battery Life Options which are designed to help with these tasks .
M1 Macs now deal the jobs themselves , with the system monitor your action and powerfulness requirements to protect the battery grade .

Input devices connected via Bluetooth
In the Bluetooth place setting in System Preferences on an M1 MacBook , underAdditional Options , you wo n’t see the configurations forOpen Bluetooth Setup Assistant at startup if no keyboard is detectedorOpen Bluetooth Setup Assistant at startup if no mouse or trackpad is detectedif said accessories are not present .
This is n’t exactly surprising , as MacBooks always have a nonmigratory keyboard and trackpad available , but the same omission appear on the Mac mini M1 as well .
We usurp that Apple has just permanently enabled the Bluetooth Setup Assistant to launch if it does n’t smell any stimulus gadget , as the feature still influence . More of an aesthetic alternative than useable one .
Using one Mac as a hard disk for another (Target Disk Mode)
M1 Mac users may notice that in theStartup Disksection ofSystem Preferencesyou’ll no longer findTarget Disk Mode . This might seem a worry , as that place setting was antecedently there to earmark an Intel Mac be used as a hard drive on another Mac via a Thunderbolt connexion .
There is no Target Disk Mode on an M1 Mac , however you may still reach a similar outcome :
