Plus, if I add them, I get the same error (I will provide later). I completed the macOS High Sierra installed, mounted and authenticated to the Time Machine server, and accessed the Time Machine backup sparsebundle. I don't have the exact error messages with me, and I'll update my question later with the exact errors and possibly screenshots. So, I chose "Other Location" and I specified the server and SMB share name, and it added it but then said the share was unavailable. I waited 8 hours, and still it didn't find them. However, at the point where it asks if I wanted to transfer from a backup, I chose that option but macOS won't find the backups. Since I could not longer boot the MacBook Air and I was sure I had two good backups, I wiped the Mac and installed macOS High Sierra from the recovery partition. I also did a "Backup with Consistency Check" on each of the two drives and I did a "Verify Backups" and all was fine. In the Recovery app window, select Reinstall for your macOS release, click Continue, then follow the onscreen. We have a two Drobos attached to the server and our Macs backup to each Drobo in round-robin fashion. Choose Apple menu > Shut Down, press and hold the power button until Loading startup options appears, select Options, click Continue, then follow the onscreen instructions. I ended up turning off the machine and my drive was no longer bootable.īefore I did this, I made sure I had two backups on our macOS Sierra Server, configured with the Time Machine Server. It rebooted and entered a black screen while the machine got very hot for about 30 minutes. applicationpath /Applications/Install\ macOS\ Sierra.I tried to upgrade a MacBook Air from macOS Sierra to macOS High Sierra. Sierra.app/Contents/Resources/createinstallmedia -volume /Volumes/ MyVolume Does this just get posted to the end of whatever is there now? it said to type the following command in Terminal. Question 2 - I was looking at the link you provided for the bootable USB. Some users reported their Mac was running slower after the macOS High Sierra update. Try giving the system some time to configure itself. macOS High Sierra is slow or freezes at random. Isn't there the same potential for bringing over things from the old SSD that I wouldn't want on the new SSD? Restart your Mac and repeat the backup using Time Machine. However, wouldn't I have the same potential issue if I am installing High Sierra with a bootable USB and then restoring files from Time Machine? It sounds like you're recommending this option over the other but I am not clear on how that makes any difference if I then end up using Time Machine to restore my old files. You mentioned that when I go into Recovery and restore from a Time Machine backup that this will do a clean install but could also restore some things from the old SSD that I don't want back. A clone backup with Carbon Copy Cloner or Superduper or Prosoft Data Backup will give you the full system without archives, and can be verified easier as complete because it is able to boot your system from Apple menu -> System Preferences -> Startup Disk. Note Time Machine itself only stores the first backup it made when first run, the last backup of any changes to the system from the first backup, and intermediate archives of what it was able to fit on initially, daily, weekly, monthly, and yearly backups on the destination backup. Note: the backup you make under any older system will contain applications that no longer work under High Sierra.īe sure that this link is checked for any compatibility issues before you proceed. When you are done with that, you can use Time Machine to restore your old backup. If the App Store is not available from the restore or internet restore, you may need to restore El Capitan first, and then upgrade immediately to High Sierra after that from the App Store. It is the first MacBook that allows that built-in. If by "clean" you mean erase and install, be mindful that your Macbook will let you erase the hard drive when booted off the restore partition, (command-R boot), using Disk Utility, and then install Mac OS X 10.13 directly from the App Store after that. Mac OS X has never had a "clean install" option.
