Where is the format APFS on Monterrey and Ventura OS?

Boy what a can of worms. I am trying to format a USB Drive to APFS so I can put Big Sur on it for contingency purposes. That format is not found on either of my machines under Disk Utility which show ONLY the two Journaled formats. I attempted this also at the beginning of the installation procedure on the Monterrey machine which also only shows the Journaled formats. The installer insists that APFS be the disk format and will not accept Journaled.

From this, I have to assume that APFS can only go certain types of drives.


What is going on?

p.s. this is an extintion of the dual drive on my Monterrey machine

@BDAqua already explained what to do, but so far your pictures of Disk Utility show you have not modified Disk Utility's "View" setting. Within Disk Utility you need to click "View" and select "Show All Devices" so that the physical drives appear on the left pane of Disk Utility. You must select the physical drive to erase in order to get the option for other file systems. If you only select an existing APFS volume, then you can only select APFS as the file system since the APFS volume is part of the hidden Container which is an APFS Container.


FYI, never erase the whole physical drive on an Apple Silicon Mac's internal SSD since several hidden APFS Containers are required just to access the Apple Silicon Mac's special boot modes. It is Ok to erase the whole physical external drives.

OK!!! Just another example of INITIAL NOMENCLATURE CLASH. My intentions were: Machine 1, Machine 2 and Machine 3. Will attempt to move that over to Computer 1 (C1), etc...

Understand about the APFS, MBR and GUID incompatibilities which is basically the access problem of this subject.


Now, lets compound this even more. ALL the previous was on C1 (Ventura) and got caught up in something else and did not extend that to C2 (Big Sur/Monterrey) for investigation.


As noted before, Big Sur Install shows APFS GUID on Disk Utility but shows Journaled under Get Info. A further check on ** shows the gamut of for Format and Scheme; i.e. four setups for APFS, two for Journaled and two for PD. Under Scheme shows GUID, NBR and APM.


Now switch over to a 64G USB and it only shows Format: two Journaled and two PC formats. Shows all three of Scheme and after clicking on GUID the get all the formats as well.


Just went back to C1 to check and the USBs from before now showing all three Schemes and all Formats under GUID.


Guess this has been answered but do not understand why or how since just a very short time ago those Scheme did not show GUID AT ALL.


I have not checked but there should to be something under Help about APFS and GUID, where it is found and how it is used.


Tks for all the help especially in getting me to troubleshoot LOGICALLY instead of haphazardly. I should know better having been a troubleshooter of other electronics systems for almost 20 years before retirement.

1 problem... MBR cannot do APFS, eeds to be GUID.

You provided lots of info but to be clear out here it'd be best to not use M1, M2, or M3 as that nomenclature is for Apple's new Silicon CPUs.


Master Boot Record (MBR) can be used in NTFS format and is only compatible with Windows computers.


So if you could clarify for me...

C1 is running which OS ?

C2 is running which OS ?

C3 is running which OS ?

Just for grins I plugged in my "BIg Sur Install" (USB A) drive on Monterrey, went to "Disk Utility", selected the install icon and clicked erase. LOW AND BEHOLD not only the Journaled formats come up but five different APFS formats show up.

This then tells me that for some odd reason that it seems to be drive specific but no hint on how that is selected. At present, all my USB Drives, other than installs, are set for Journaled which now seems to indicate that one a drive has been formatted into Journaled it will never be able to be formatted into APFS.

All this was done on the Ventura machine with the exact same results including using both methods of trying to install the OS.

Just another thought that may be causing this, that somehow there are particular Drives that have already been set to APFS and those are the only one usable for the APFS installation.

One the USB drive, there seems to be only one selectable. Only the internal data/OS drive show more than one on the Ventura machine.


On the Monterrey machine, everything is all fowled up with three drives showing as 'data' which are labled which I had labeled, one for Big Sur and one for Monterrey with only the Big Sur showing the volume. i.e.

Batestar 03 10.14 (dims when selected)

Batestar 03 10.14 shows active

Batestar 03 11.4

Com Apple US update. . . . . . . .

Batestar 03 11.4 Data


As noticed, all of these show on the internal drive. There are two external drives that only show the volume.

Get info shows: all four of the Batestar 03 volumes as APFS. Both external (USB Drives) show Journaled though on the disk utility the Big Sur Install shows all of the available formats, Journaled and Apfs, while the unused only show the two Journaled formats. (this is on the Disk Utility). to date, the Big Sur Install drive is the only ont that shows the APFS formats among the twelve or so USB (A and C) I am using.

Maybe it would be best to start all over with this as we/I seem to be chasing RAREBITS and getting off the subjects.


Image one is the "Get Info" of the drives on Monterrey/Big Sur (this is a secondary problem that is causing some of the rarebits (M2)


Image two is desktop screenshot of the Ventura drives (M1)


Image three is a third computer with multiple OS's (no part of this problem except for USB formatting)(M3)

Note M1 is the only one with an operational backup drive. M3 backup showing problems and not active.

M1 also the newest machine (2022 model); M2 is a 2018 model and M3 is a 2013 model. When m2 booted into Monterry it seems to be maxed for OS. M3 is maxed for OS with USB Drive OS 10.11 El Capitan but use with 10.6 (Apple works) if I can get it installed again. That 10.9.2 is the drive from an ancient Dome Mac which is PPC but have it for the data only on the drive.


At the present time, M2 is somehow booted into Big Sur but showing identical information as if booted into Monterrey. Not discussing this at this time other than what is happening on Disk Utility with both showing identical information. Only difference is which disk image is on top as active.

M1 is presently booted into Ventura.


Here we need to pick up the Disk Utility images from M1 and M2 a couple of notes above.


To answer that last question: I do not know other than getting error messages about the GUID Partition.


I just received a brand new 1T USB drive but it is USB C and I need USB A for M2. I have multiple 64mb USB C's available along with a 256MB that I am trying to put Snow Leopard (10.6) on for use with AW but it is available.


(((((S T O P A N D R E C E N T E R problem)))) - - - Formatting USB drive to be used as External OS installation.


All USB drives indicate they are formatted as Journaled and only show the two Journaled formats when attempting reformat on both M1 and M2.


Only the Big Sur Install USB Drive picks up the APFS submenu but shows as formatted Journaled (4th info below).


Working with the 1T, presently unnamed, and the 256M USB drives presently mounted on Ventura. Screen show of Disk Utility added. Disregarding all references to PC info.


Select Volume: USB Sandisk (data only - used for info only) . . . Select Erase and dropdown menu only shows journaled with scheme Master Boot Record. Cancel and select Batestar 06. Select Erase and dropdown menu only shows journaled without scheme line.


Select Volume: SanDisk Ultra Media (unformatted 1T). . . select erase and dropdown menu only shows Journaled with scheme Master Boot Record. Cancel and select UNNAMED. Select Erase and dropdown menu only shows Journaled without scheme line.


OOOOPSSSS! Just noted that there is an additional pick on Scheme as Apple Partition Map which I now suspect as GUID Partition SCHEME???? However, still nothing about APFS under Format when applied. Now also understand that MBR reference. BOY DO I HATE INITIAL ACRONYMNS!


Now just wondering if it is necessary to format to Journaled APM and then use MAY get APFS for the Volume???
