![]() ![]() I then started up the Mac pressing Option/Alt, and I saw all three options ("Macintosh HD", "Windows", and the Monterrey startup disk). I cannot boot into the Recovery partition.ĥ- I created a bootable USB drive (using Monterrey) and plugged it into the MacBook. If I choose Macintosh HD, I get the spinning circle/reboot cycle.Ĥ- If I restart the Mac while pressing command-R to get to the recovery drive, I again just get the spinning circle/reboot cycle. The Boot Camp control panel showed up, and I could select MacOS from there.Ģ- When booting up into MacOS, I get a momentary spinning circle (dots) after which the computer reboots - this cycle keeps repeating itself to no end.ģ- When booting the MacBook while pressing Option/Alt, I *do* see two partitions: "Macintosh HD" and "Windows". I did find the Boot Camp app under "Program Files" and ran it. From the Windows desktop that does work, I noted that there is no D: drive (no MacOS partition), and there is no "Boot Camp" app in the Task Bar ^ menu. One works and launches the Windows 10 desktop, the other produces (Windows-based) error messages and offers to fix the corrupted drive instead. He gave it to me to have a look, and here's what I found:ġ- Windows boots fine, but there are two Windows 10 installations to choose from on startup. Since doing so, he has been unable to boot back into MacOS. My friend's teenage son installed Boot Camp on his 2019 MacBook Air. Enter the password you would use when logging in to your Mac to decrypt the volume when prompted.Cannot boot or recover MacOS (even from USB installer drive or internet) after Boot Camp installation Hi all - I have searched the forum but (so far) cannot find any answers to this particular problem.Enter the following command, replacing disk1s1 with the identifier you previously noted: diskutil apfs unlockVolume /dev/disk1s1.Make a note of the volume identifier, for example disk1s1.Open a Terminal window and find the (APFS-formatted) volume you would like to mount using the diskutil apfs list command.If you are using macOS, try the following: If the drive is encrypted with FileVault, this may be a lot harder-especially if you're not using macOS for the recovery process. Will Haley's blog has an excellent account of navigating this process, from finding an adapter to mounting the HFS+ partition in Linux. Unfortunately, getting another machine to recognize your drive might be the biggest stumbling block. There are interfaces for M2 and NVMe drives that can make this process much easier, while a SATA to USB adapter will work for older SSD and HDD models. With the drive removed, you'll need to work out how to attach it to another computer or a Mac. Most Macs now use M.2 or NVMe drives, some with proprietary connectors. If the Mac is especially old it may have a mechanical hard drive or an older solid-state drive. You will probably need a set of TORX screwdrivers for this, and you should take precautions like using an anti-static wrist strap and safely storing the screws until you need them again.įrom here the directions will ultimately depend on the drive. With this information, head to iFixit and look up your Mac model to find out how to get into the chassis. You'll find the serial number printed on the outside of the chassis somewhere (on the bottom of your MacBook, for example) which you can then plug in to to get your precise model, year, and release date. The first thing you should do is look up your Mac model. Since there is a lot of variance in the types of drives Apple uses, specific instructions will differ depending on your device. One last option is to physically remove the drive inside of the Mac and mount it in another computer. Make sure the Apple Silicon Mac (that you want to share from) is turned off, then press and hold the power button until you see "Loading start-up options" on the screen. This is very similar to Target Disk Mode, though it works a little bit differently.įirst, connect your two computers using a USB, USB-C, or Thunderbolt cable. If you're trying to share files from an Apple Silicon-equipped Mac with an M1 chip or later, you can use Mac Sharing Mode.

At this stage you can transfer any files you may need. If the drive is encrypted with FileVault you should be prompted for the password which macOS can use to decrypt the volume. The source Mac's drive should appear on your desktop (or in the Finder sidebar under "Locations") once Target Disk Mode has been initiated. Now turn your attention to the second Mac. ![]()
