The two volumes are present "Mac SSD" and "Mac SSD - Data". However, the "Mac SSD" volume is NOT mounted, but instead, an "APFS System Snapshot" within the Mac SSD volume is mounted and seems to be where macOS is running from.
How do I fix this?
How I Got Here...
Yesterday I had ... 2018 15" Macbook Pro w/32 GB RAM + 2TB SSD running macOS 10.15.7.
There has been a growing list of oddities, so want a fresh start NOT restoring from my TimeMachine backup.
I created a new APFS Volume and called it "Mac SSD"
I installed Big Sur 11.2
Started to install all my software and data
Booted back to Catalina and noticed odd drives on my desktop
Checked Disk Utility, booted back to Big Sur, Checked Disk Utility
And here I am ... very confused.
M1 MacBook Air, macOS Monterey 12.4, never reinstalled the OS, Time Machine disabled, but still shows that it is running from a snapshot:
Also, if I actually check disk snapshots from Onyx or terminal, it says that there are none:
I don't think this snapshot is somehow created by the Time Machine, but rather it might be created by macOS update utility to restore to the previous version if update goes wrong. Although I do not have any real evidence to prove this point, I'm quite sure you shouldn't be worried about your macOS setup not being clean or stable.
Sorry for my English, not a native speaker.
It turns out that the snapshot is an intended security feature of macOS 11 and higher.

Well this is embarassing...
I'm a college student with an apple developer's license.
I'm currently stuck in the CMD+R recovery partition.
I installed 10.10 successfully earlier today. Then I got the bright idea to format my drive and do a clean install of Yosemite. When I clicked the 'Reinstall OS X' button in the recovery screen I recieved a message telling me that my computer cannot be verified with apple. I'm guessing this is because the recovery drive cannot recognize or download/install my developer certs.
Any ideas on how I can fix this? I'd prefer to install 10.10 but I'll roll back to 10.9 if absolutely necessary.
EDIT:
I solved my problem by doing an internet recovery (Cmd+Opt+R at startup). From there I installed 10.8 and re-installed 10.10 from the mac app store.
If you downloaded it from the developer site, you should have went through redeeming a code step, then Yosemite should be in your purchased app list. Are you sure you are using the account you redeemed the code? If you get the image from someone else, you probably want to redeem the code from the developer center.
I was able to get a clean install by booting to an external Mountain Lion disk and running the installer from there. More info: http://themainthread.com/blog/2014/06/clean-install-yosemite.html
I solved my issue by re-installing 10.8 onto my main partition and updating to 10.10 from there.
Since apple has not released OS X Yosemite to the public they can't verify the software because the recovery mode disk utility is for non developers, the software is not in the apple system yet. You should just make a bootable usb and do a clean install of OS X Yosemite.
Items to try:
1) Repair Permissions (better if booted into Recovery HD)
2) Resync time with Apple's Servers via System Preferences
...if all else fails, you can nuke and pave, or create a bootable USB installer.
I am brand new to Apportable. I installed and am able to launch the sample Spin app on my Android device. However, after launch, my system is completely frozen and will not respond to any trackpad or keyboard touch. I hard booted and tried again with an iOS app I developed with the same results.
System:
MacBook Pro 15" Early 2011 running OSX 10.9
16GB RAM, 20 GB disk space available
Xcode 4.6
Any ideas why this is happening and what I can do to prevent it? Thanks!
Sometimes while copying the apk to the device, the USB driver gets blocked for a few seconds. If this is the same issue, then your system should return to normal pretty quickly (no more than five seconds on most machines).
If that isn't the case for you, you can try the following command:
MTP=no apportable load
If you still have the issue after that, something else is going on that I have never seen.
I had the same problem and MTP=no apportable load solved it for me.
Recently i upgraded to mountain lion.I want to open my old projects in older version of xcode 4.3 and i don't want to use xcode 5 for some reason.
Is there any way to open xcode 4.3 only. I have installation file of xcode 4.3 if its needed to reinstall.
It gives alert "This installation of Xcode 4.3.2 requires Mac OS X 10.7 Lion."
I know how to run my projects in other versions with old simulators... but only need 4.3
Any Suggestions?
Ignore the snarky comments by people like matheszabi; there are good reasons to support the millions of units of older devices. Tip: If you are looking at picking up older devices, you'll want to target iOS 4.2.1 not 4.3, as every device supporting 4.3 can be upgraded to iOS 5. See Highest Version of iOS Supported.
Virtualizer
To answer your question, "Any suggestions?": Use a virtualizer like Parallels, Fusion, or VirtualBox to run Lion, Mountain Lion, or Mavericks in a virtual environment. This arrangement has many advantages, including resisting the pushing and shoving of Apple to constantly upgrade our OS, Xcode, and iOS targets.
Another advantage is a pristine working environment with its own clean Keychain, Desktop, and so forth having only items related to Xcode project(s). All my own personal stuff is kept to the real Mac. I think of the real Mac like I do my home, with personal property, while I think of the virtual Mac as my office space, my cubicle, having only work-related items.
The one thing you'll need is memory (RAM). If you want a 3 or 4 gig virtual Mac, you'll need about that much space unused on your Mac. By unused, I mean the green colored piece of pie in Activity Monitor.
My Experience
For my current project, I run Xcode 4.6.3 targeting iOS 5 & 6 in Parallels 8 (9 is now available) on a Mac mini (Late 2012) with 16 gigs of memory and i7 quad-core with 8 virtual cores driven by Mountain Lion 10.8.5 on the real Mac, while the virtual Mac has 4 gigs of memory and 2 cores. For the most part this works very well. A few bugs, but no show-stoppers.
The only bad bug is that copying text from the real Mac and pasting into the virtual Mac appends an extra mysterious invisible character that wreaks havoc, including preventing compiling of Objective-C code. I routinely do searches for that evil character, and try to make a habit of hitting Backspace after pasting text brought over from the real Mac.
Another bug: Horizontal scrolling by finger-swiping on my Apple Magic Mouse does not work in the virtual environment.
But Parallels 8 + Mountain Lion + Xcode 4.6.3 works well. You can plug in an iOS device for direct debugging via USB cable – Parallels asks whether you want the connected device to be seen by the real Mac or the virtual Mac.
I've also run earlier versions of Xcode 4 on Lion (besides Mountain Lion) in Parallels 8.
With this arrangement, I am free to consider upgrading my real Mac to Mavericks while keeping my Parallels 8 + Mountain Lion + Xcode 4.6.3 work environment intact. Though, I may need to shell out some money to upgrade my Parallels 8 to the new version 9. No such thing as a free lunch! (But this arrangement comes close)
Backups
Tell Time Machine to avoid backing up the 20-50 gig file that is your virtual Mac's hard disk. Instead, do an occasional backup of that large file. More often, make a backup of your import work files and Xcode project, copying off to Dropbox, Google Drive, or external hard drive or SD card. If that file that is your virtual Mac's hard disk ever gets corrupted, you may lose everything. So backup religiously – though I'm sure you do so anyways now. ;-)
Looks like Xcode 4.3 doesn't know about Mountain Lion, the fix would be downloading and installing Xcode 4.6.2 from developer center, which surely supports it.
I would like to know if I can install Xcode with Windows XP.If possible please provide the document link also.Thank you very much for any help in advance...
It's certainly possible.
There are two routes;
Install OSx86 (aka iATKOS / Kalyway) on a second partition/disk and dual boot.
Run Mac OS X Server under VMWare.
The first route requires modifying (or using a pre-modified) image of Leopard that can be installed on a regular PC. This is not as hard as you would think, although your success/effort ratio will depend upon how closely the hardware in your PC matches that in Mac hardware - e.g. if you're running a Core 2 Duo on an Intel Motherboard, with a NVidia graphics card you are laughing. If you're running an AMD machine or something without SSE3 it gets a little more involved.
If you purchase (or already own) a version of Leopard then this is a gray area since the Leopard EULA states you may only run it on an "Apple Labeled" machine. As many point out if you stick an Apple sticker on your PC you're probably covered.
The second option is the more costly. The EULA for the workstation version of Leopard prevents it from being run under emulation and as a result there's no support in VMWare for this. Leopard server however CAN be run under emulation and can be used for desktop purposes. Leopard server and VMWare are expensive however.
If you're interested in option 1) I would suggest starting at Insanelymac and reading the OSx86 sections.
I do think you should consider whether the time you will invest is going to be worth the money you will save though. It was for me because I enjoy tinkering with this type of stuff and I started during the early iPhone betas, months before their App Store became available.
Alternatively you could pickup a low-spec Mac Mini from eBay. You don't need much horse power to run the SDK and you can always sell it on later if you decide to stop development or buy a better Mac.
No. You can not install XCode on a Windows machine. You need MacOS to run XCode.
Although you can install VMWare Server on your windows machine and then install MacOS on that virtual server and can install the XCode on that MacOS server.
But to install MacOS(VMWare server) and start working on it. your hardware must support virtualization.
To install VMWare following links might be useful.
http://www.petri.co.il/virtual_install_vmware_server.htm
http://www.virtuatopia.com/index.php/Installing_VMware_Server_2.0_on_Windows_Systems
Or there is always Google.
YOu can check if your CPU supports virtualization here.
Since Xcode is an software of Mac OS so its not possible to run Xcode without Mac OS. And for Mac OS you can dual boot your computer with a Mac OS or simply you can just use VMWare to install Mac OS in your laptop or PC. Just the necessary requirement for installing Mac OS through Dual boot or through VMWare is that you need really high configuration in your laptop or PC, Like atleast you require 5th Generation core processor with atleast 4 cores also you require more than 4GB RAM for better functioning of Mac OS. Mac OS can be installed with 2nd generation processors, Dual core, and 2 GB RAM but it will take too much time. Which is not worth installing Mac OS in your laptop or PC. And even after installing you won't be able to use Xcode efficiently with such a low configuration. So it is recommended to have 5th Generation processor with 4 core and atleast 4GB RAM.
If you have this configuration than you need some files and software to install Mac OS in your Laptop.
For installation through VMWare you can prefer to this video: https://www.youtube.com/watch?v=wodqGvug6e0
And I have the required file for the same as in video but not uploaded to the internet.
I want to Install any smooth working version of XCODE(for Iphone Apps development) on MAC machine having configuration as follows:-
MAC OS Z1-9.2.2,
Built In RAM-128 MB,
MAC OS ROM 9.0.1.
What are the feasibilities with that MAC.
Please help as I am just One day old for MAC.
No, it's not possible. It requires a modern Mac OS X. Xcode4 requires at least Snow Leopoard, and IIRC so does the current Xcode 3.2.x.
Even if it were possible, my Xcode4 right now occupies about 590MB of RAM at the moment of this writing. You wouldn't want to run something like that on a system with just 128MB RAM.
