I recently set up a new APFS volume to support dual boot for the macOS Catalina beta alongside my Mojave install. Unfortunately, this new "beta OS" volume seems to have set itself up as the default boot volume.  How can I change the order of volumes so that the more stable OS takes priority?

I set Windows 7 to my Boot Camp. Windows 7 starts now by default in the normal boot. However, I want that OSX boots by default and Windows 7 only as I press ALT and then select it.  How can you set OSX to boot by default?

I have Mac OS 10.7.4 and I'd like Finder to use "Is Folder?" as its first sort criteria, or in other words, group folders before files regardless of the sorting method.  Windows and Linux both do this by default.

I have a MacBook with 1TB SSD. I want to have two separate partitions with two independent macOS installations. I want to make sure that none of the partitions have any kind of possibility to interact with the other, I want them to be as separated as if they were physically separate. Is this achievable with, for example, FileVault for each of them? Edit: My question is neither &quot;how can I install two different macOS versions on two different partitions on one SDD&quot;, neither &quot;how do I use FileVault&quot;, etc. I know how to do all of that. I want to make sure that there is no interaction between the partitions possible. Can this be made sure with the above approach? Is it sufficient?

Using Mac OS X 10.4  I made a script a while ago for my linux box in order to take archived data off of 300 floppies that automated the process. I would make an image of the floppy and copy the files directly off of the floppy. I managed to install xcode on the machine (in order to install ddrescue)  The thing is on a linux box I mounted each floppy to /media/floppy and unmounted it to ddrescue it and copied it directly to a usb drive.  I'm trying to port my script to the mac, and it seems that it's default behavior is to automatically mount each zip floppy to the /Volumes folder, which is fine, except it uses the volume's name as it's mount point folder name. So if a floppy's volume name is, "Jimmy Bo Bobs" it will mount to /media/Jimmy /Bo /Bobs.   So my question is I need to get the volume name either consistent to one name, or adaptable to the volume's name.   So my initial question is can I some how mount a drive to a specific folder, Like I would normally do in linux?   #Linux  mount /dev/sd1 /media/floppy  #Mac  diskutil mount /dev/disk1s1 /media/floppy #Doesn't work   If it's not possible, is there an easy way to extract the volume's name so that I can then link the script like this.    Volumename=Jimmy Bo Bobs  do stuff to /Volume/$Volumename   I'm guessing if it's not possible I'll have to grep the mount command to the /dev/ pointer and then somehow parse that string which is what I want to avoid since it would require even more research.

I have a Macbook that runs Catalina OS, but I would like to have a VirtualBox version of it.   I was able to successfully download Catalina from the App Store, and followed a tutorial to convert it into an .iso image. The problem now is that whenever I try to launch it in VirtualBox all I see is the UEFI Interactive Shell v2.2  The shell displays a Mapping Table and it just hangs there waiting for a command.

Prior to Mojave 10.14.4, macOS would automatically attempt to mount locked Core Storage volumes, and if the necessary password was found in the current user's keychain this would occur automatically.  I've taken advantage of this behaviour until now to allow me to have multiple encrypted volumes that are all mounted automatically by successfully logging in to a user account on my encrypted startup volume.  However, macOS no longer appears to be attempting to mount Core Storage volumes automatically, despite the necessary passwords being in either my user keychain, or the system keychain, forcing me to mount them manually with Disk Utility. This isn't ideal as it ties the volumes to the user account, meaning if I log out the volumes are locked again.  This behaviour differs from encrypted APFS volumes, which mount automatically exactly as before. I know Apple is pushing us to move to APFS, but with still no conversion for AppleRAID (I'm not keen to erase and restore a multiple terabyte volume just to switch), and no use for Time Machine which still doesn't support an APFS backup volume.  Is there a way to restore or securely emulate the previous behaviour such that the volumes are unlocked automatically for all users?  In case the specifics of my setup are useful; my startup volume is an APFS encrypted volume that only my admin account is authorised to unlock, but I use other, standard, user accounts (one for work, one for general use etc.) when actually using my system. I then have an AppleRAID volume of several disks using Core Storage encryption, and a CS encrypted Time Machine disk.

After upgrading to macOS Sierra, I'm getting the notification that "Your disk is almost full. Save space by optimizing storage.":    The options appear to be to store my files in iCloud, automatically delete files, or manually delete files:    My problem/irritation is that I have 80GB free of my 440GB volume.  The question: is there a way to silence this notification in a (semi-)permanent fashion, or to change the threshold it uses for the notification?

New mac user here (Linux background). I'm running macOS Catalina (Beta5). I've noticed there are 5 volumes in my main disk container. One is mounted at /, that I understand, it's the system, another is /System/Volumes/Data, which I tough it would be the Linux /home, but it's not, so what it it?  Also what are the other two unmounted volumes? One might be the recovery one, but the other? Thanks!

IIRC then the mount options shown in /proc/mounts have changed. Some time ago acl and user_xattr were shown, now it seems that only noacl and nouser_xattr are shown if these features are turned off.  Where is this configured? Does that depend on the compiled-in defaults of the filesystem code? How can I check whether a volume supports e.g. ACL? Is there a better solution than testing with setfacl, getfacl?

My /boot is full. Is there an easy and safe way to resize it? I saw a discussion which said that /boot partition is not required. A /boot directory will be fine. However, I don't think I can have /boot folder while /boot is mounted. Similarly, I can resize /boot because I can't unmount it.  I plan to 1. create a new logical volume, 2. mount it and copy all files from /boot to this new volume, and 3. change mount table to mount new logical volume under /boot.  Since it's /boot, I won't be able to boot if I make mistakes. Could anyone give me instructions?  Steve

I have macOS High Sierra installed on my MacBook Pro already with the APFS format.   However, I would like to know the steps involved to perform a clean installation of macOS High Sierra with the APFS format?

On my Mac OSX Mojave machine.. I installed Ubuntu 18.04 to attempt to dual boot on the internal Apple SSD. Worked for a while, but after some updates to Ubuntu... hitting the power button boots up to a GRUB terminal, and when hitting the option key there is no 'Macintosh HD' as a startup option.  I have seen 2 similar posts on this topic, but none of them appear to exactly match as far as partitions go  and  and I am hesitant to try something that would wipe out or corrupt my OSX data that I know is still on the SSD/drive.  When booting into recovery media, I executed the following command to list disks:    I notice the partition FFFFF-FFFF...  I then do a disktuil info /dev/disk0s2 to look at the info.    I then use GPT to check...  gpt -r show /dev/disk0     What can I do to make it so that I can fix my OSX boot partition without losing any files. The disk that my OSX files are stored are on disk0s2, which is the FFFFFFF partition... how do I fix up my ability to boot into the OSX Mojave without wiping out my data or is there a way? Does APFS have anything to do with this?  At this point I don't care about the Ubuntu 18.04 partition, but I do not want to lose any data on the 900+GB partition, which is all my the Mac files are.

I just finished the huge download of Mac OS X Lion, started the installer, and now I have a problem. The installer says that I must have the GUID-Partitions Table Scheme.  The problem is that when I go into the disk utility, I can't change the format anymore, because I have Master Boot Record as type.  Can anyone help me, please?

I can't figure it out how to sort folders by name in Finder.   My expected results should look like this:  0629e7bc-8110-4db9-aaa9-b67b0b73743d 06a409e1-98c6-4bf4-afa4-c814f7899d82 0a3a5c12-e459-4aa0-b9cb-30b544013215 0c14581f-31d8-4961-a14f-11afc40e47f9 0fe8970c-6338-46ca-bc16-f7867b271480 129855c4-7dbe-4a9f-a100-28b1d3d02340 1522e288-8a81-4298-aefc-f334cb088a53 180d430b-76f9-401f-845a-cb395bc1eba0 1a01a936-bedf-4758-971a-d4886ee8d281 ....   But instead it looks like this:    Here are my settings:    Grouping is turned off.  I think this is a bug.  (grouping doesn't change anything here). I've deleted .DS_Store files.   I am running macOS Mojave 10.14.5 (18F132)  Even if I switch to another view, it does not work.    What else could I try to fix this?

I've searched and tried a lot of stuff but still can't get it to work.  I was able to use my seagate HDD properly last week but now it doesn't mount. I tried plugging it to a PC &amp; another mac, it works fine on both. The reasons could be    Updating OS to macOS Sierra  Not ejecting properly Installed sims4 with wineskin   Things I have tried.   From disk utility clicking on mount &amp; first aid.  From terminal writing: diskutil mount disk2s1 &amp; diskutil mount readOnly disk2s1 both resulted with this  Volume on disk2s1 failed to mount If the volume is damaged, try the "readOnly" option From terminal writing: diskutil repairDisk disk2s1 &amp; diskutil repairVolume disk2s1. Restarted mac in normal mode &amp; safe mode. /private/var/log/install.log from here found some logs but don't know what to do with them.  Switch USB ports &amp; retry. A couple of other things.

I'm going to be upgrading my Macbook Pro (mid-2012 model) from its original OS X Lion 10.7 installation to a newer version of macOS. It looks like Apple will allow me to upgrade from Lion directly to OS X El Capitan 10.11 and macOS Sierra 10.12, and from there all the way to macOS Mojave 10.14.  I have heard that upgrading to a newer OS can cause performance issues, especially on older hardware. How can I find out about these issues, so I can determine the best version of macOS to upgrade to?
