If you want to change the password, you need to decrypt it and then use APFS with encryption afterwards. You can still decrypt HFS+ volumes, but that's it. Disk Utility does not even list Mac OS Extended with encryption as an option any longer and the other way to do this so far – right-clicking the volume and clicking encrypt – also just creates a new APFS container with encrypted volume, partitioning your drive between HFS+ and APFS. Any attempt to encrypt an HFS+ volume, will result in a new APFS container (with encrypted volume) to be created. I've been using external drives formatted as Mac OS Extended Journaled (HFS+) with encryption for a while and noticed that Big Sur can not create volumes formatted as encrypted HFS+. Either way, that takes a few minutes.I thought I'd share some observations I made after having recently updated to Big Sur, with some big surprises regarding external drives.

To start up from your OSX Install disc, insert it in the SuperDrive (or insert the Software Reinstall drive on a MacBook Air). (If you're not sure what version of OSX you're running, click here.) Be sure you use a compatible version of OSX - if you’re running Lion, use a Lion disc if you’re running Snow Leopard, use a Snow Leopard disc, etc. If all else fails, start your Mac up from a different source: the Recovery HD on Lion 10.7.x or later (see Using the Recovery HD), or your OSX Install disc (Software Reinstall drive on a MacBookAir), or a different disk that has OSX installed on it.
Exclude it from Spotlight indexing, via System Preferences > Spotlight > Privacy.If you're running any anti-virus software, exclude the disk from it or turn it off.If you get a message saying " Could not unmount disk," some other process is using (or trying to use) the disk: If in doubt about them, see Disk Formats. Set any other partitions to the desired format. Effective with Lion 10.7.x, you can encrypt the backups, per Question #31.If any disks/partitions being backed-up are case-sensitive, the backup volume must be, too, so select Mac OS Extended (Case-sensitive, journaled).For your Time Machine partition, there are two considerations: Usually, that will be the default: Mac OS Extended (Journaled). For each partition, click on it (it will then be outlined in blue), then supply a name (this is the name that will appear on your desktop and/or Finder sidebar) and size (either by typing in the box or dragging the dividers in the diagram).Į. Sometimes you can't change a MBR drive to GUID or APM and change the number of partitions at the same time if that happens, make a single partition with GUID or APM first, then re-format with the desired number.ĭ. Select the Partition tab, then set the number of partitions from the pop-up menu below Volume Scheme (use 1 partition unless you need more). See Troubleshooting item #E7 for a detailed explanation.Ĭ. Most of the time there's no difference, but if the backups are case-sensitive, there may be problems when restoring previous versions of files via the Time Machine browser (the "Star Wars" display). So if you have, or think you might add, a case-sensitive disk, make your backup disk Mac OS Extended (Case-sensitive, Journaled) now.īut if NO disk/partition being backed-up is case-sensitive, the backup volume can be case-sensitive, but we recommend it be case-ignorant: Mac OX Extended (Journaled). There's no choice: that’s the only way Time Machine can back them up. If ANY disk being backed-up is case-sensitive, then your backups must be case-sensitive also. (Effective with Lion 10.7.x, they may also be encrypted.) Most are Mac OX Extended (Journaled) see if any are Mac OS Extended (Case-sensitive, Journaled). Click each partition in the sidebar (indented under the main line of the drive), and you'll see the Format towards the lower left. Do not use case-sensitive unless you're sure you need it.Ĭheck the Format of all the disk/partitions to be backed-up, via Disk Utility, in your Applications/Utilities folder. That's the default if Time Machine formats it for you, but non-case-sensitive (also known as case-ignorant) is the default for all other volumes.
A case-sensitive format means upper-case letters in file names are seen as different from lower-case letters. Case-sensitivity on Time Machine backups.
