![]() ![]() UPDATE: 6:01pm PT: All’s well that ends well. A bit of a rocky start, but things are settling down. As for the Big Sur OS itself, I’m loving the updated look and typography and design (see Engadget Big Sur review). I’m running the 11.1 Beta which is rock solid. As for the Chrome crashing, Big Sur 11.1 seems to fix it. I learned that likely has to do with Spotlight re-indexing the system for search which completes within 24-hours or so. UPDATE : Turns out Big Sur resulted in extreme battery drain and also frequent crashing of Chrome, at least on my MacBook Pro (2016). Big Sur Beta Version 11.2 is most recent. But for personal use I’d say give it a go (backup your data first please!). Obviously big caveat: this OS release is still in beta, and I wouldn’t run it on a production or mission critical MacBook. It would have made my initial attempts to eliminate the old/un-updated Apps/Extensions that were infecting my wife’s computer.UPDATE : So far the new Big Sur Beta releases from Apple have been excellent in my experience. Hope you can similarly isolate the extensions Apple/Non-Apple. I like the separation of the Apple applications (In the System.Applications folder and putting the non-Apple applications in the traditional Application folder. I made a copy of the original source Pictures folder, made an alias of the file and moved that to the target user folder. I eliminated the biggest part of the user merge (Pictures which was HUGE!) and the migrate/restore user of the new macOS set up function worked fine. Step 14 - With the new APFS secret partitions, the restore user part of the set up function did not have enough free space to proceed. Maybe the install app does some clean up needed, but bypassed by the Disk Utility restore option? Or is this now irretrievable? Thank you for any help.ĮXCELLENT! PROBLEM SOLVED. I just assumed an image could be written block-for-block to recover machine state.Īnyway, I'd be most grateful if any of you could help with this by pointing me in the correct direction. I confess, I don't really understand how APFS works or what a "volume" means in that world. Now, I know I made many mistakes in this process and I won't win any Apple Support Engineer awards but I'm sure there must be some way to recover the information in the image file. I also tried to restore the image back to the erased SSD but was met with the news that I can't restore images containing APFS volumes. But how? It seems obvious that it should be doable with the Migration Assistant, but I can't figure out how. Now, I'd like to recover settings, programs and files from the image backup. I was able to use Internet Recovery to reinstall High Sierra, but only after erasing the internal drive. I used Disk Utility in recovery mode to create a disk image before moving further (ominous music). Sadly, the only Time Machine backup is from several years ago. Unfortunately, every time the Air starts now, it immediately tries to upgrade to Monterey but crashes after 29 minutes. ![]() Apparently, there was not enough disk space (disk util said 16GB available, Monterey said less than 11GB available), so the upgrade failed. How to use a disk image to migrate after a failed upgrade? Inadvisably, I tried to upgrade from High Sierra to Monterey on a MacBook Air. Restore data using the method of your choice.Follow the prompts, and install on Macintosh HD.If “Erase Volume Group” is shown, use that instead. Click Erase, and input the following exactly: (If you cannot select erase on the main hard drive, erase the "Container" or “Macintosh HD”.).This will either be the top, non indented hard drive. Select "View" in the toolbar -> "Show All Devices". ![]() Once you are in macOS Recovery, verify you are connected to WiFi in the top right corner.Turn on the Mac, (if off) and immediately press and hold Option + Command + R until you see a spinning globe.So, you need to erase the disk, install macOS Big Sur, then transfer data manually, or with Migration Assistant/Time Machine restore. Not being able to use the "Restore" feature is a known issue in macOS Big Sur. A "seal" is part of the Signed System Volume (SSV) in macOS Big Sur. ![]()
