That is (as is probably clear to you) not how mounting works.
The contents of the /dev folder is mainly device files (as the name implies). Device files are "special files" in that they're really nodes in the file system, but the contents of these "files" are not stored inside the file system.
Device files are divided into two main types: block devices ...
Unfortunately the defaults write method does not seem to be reliable anymore.
The most reliable way I've found to do this is with AppleScript.
The downside is that it can take 15-30 seconds to run, during which time you should not do anything else with your keyboard or mouse.
The good news is that you should be able to save the AppleScript below as an app ...
Yes, there are some terminal commands to set your default setting to "none".
Disable top left hot corner:
defaults write com.apple.dock wvous-tl-corner -int 0
Disable top right hot corner:
defaults write com.apple.dock wvous-tr-corner -int 0
Disable bottom left hot corner:
defaults write com.apple.dock wvous-bl-corner -int 0
Disable bottom right hot ...
It sounds like you mistyped the command or had problems with your brew command, making the chown apply to not only /usr/local but rather / - i.e. the whole system. The command you have written is actually relatively dangerous, as you're relying on "brew --prefix" to output the right thing.
In this case your command changed the owner of system files, such as ...
Is this something that comes preinstalled in a MacBook?
No. It is a 3rd party app.
Is it okay to completely remove it?
Yes, it is okay to remove it if you don't use it. It must have been installed by the previous owner.
If this MacBook is a shared computer and it's possible that some other user may be using the app, it's safe to leave it.
Doesn't appear to be a hardware problem after all. Resetting the NVRAM/PRAM seems to have done the trick. Before doing this, the problem was occurring about every two minutes. I've now run the system for 24 hours without an incident.
Edit: the problem is back after three days. I would appreciate any ideas.
I believe I have found the culprit...iMazing...or rather, iMazing's communicate-to-iOS-device-via-Wifi feature.
At some point over the last year or so, I had installed iMazing which, for those who are unaware, is an iOS device management and backup utility. And as mentioned above, one of their features is communication with iOS devices via WiFi. When this ...
You don't need additional software for this, the standard vi installed by macOS can edit binary files.
cd /Applications/Microsoft\ Word.app/Contents/MacOS/
cp Microsoft\ Word Microsoft\ Word.orig
vi -b Microsoft\ Word
Now, assuming you are not used to vi:
Type /app-sandbox followed by Return to jump to the definition you want to change
Press Return again ...
Based on this Apple support article, I gathered that the purgeable space might be taken up by local snapshots. I had already backed up since emptying the Trash, but I have more than one backup drive. I removed the backup disks that aren't accessible at the moment and some time later my system drive's purgeable space was shown to have been alchemically ...
I have been able to repair this. It may have been luck. What I did:
Copy all private/var/db/openldap/authdata from all Time Machine
backups to a working directory (for i in 2019*; do ditto $i/DumbledoreRoot/private/var/db/openldap/authdata/ /tmp/$i/authdata; done). My boot volume is called DumbledoreRoot.
Run crash recovery on all the authdata copies, to ...
So I tried again with another apple senior advisor today as the previous one would never do what he said he would. I think the issue is solved.... Heres a screen shot of what she had me uncheck in the Messages preferences tab on the iMac and the messages are all now acting the same in syncing...
There is an app on the app store named Note2Txt that will convert each note to a text file and save it to a directory/folder of your choice. The app is $0.99 and is extremely fast and efficient. I back up my notes using this app. Each text file is given the name of the note with extension .txt
I had the exact same issue using a combination of ZFS Samba, could create files on the mounted drive when testing but trying to create sparsebundles failed.
Turns out as others have pointed out that it might have to do with filesystems used, I had to add vfs objects = catia fruit streams_xattr zfsacl for it to work.
I was stumped with some issues for days now, reading everything I could on the subject, and I finally found the solution: it is a keychain problem with as simple solution.
The solution is to delete one or more folders located in ~/Library/Keychains/, that is to say folders in the Keychains folder in our user Library.
The folders to be deleted have long ...
I am yet to see any evidence that nfsd on macOS supports version 4.
From man nfs.conf:
For more information on the NFS and MOUNT protocols see Network File System Protocol
Specification, RFC1094 and NFS: Network File System Version 3 Protocol Specification.
And as the OP points out rpcinfo localhost consistently reports versions 2 and 3 only. I have had ...
The easiest way I know to do this is with a third party app like Bartender (https://www.macbartender.com). The app is used to hide pretty much any menu bar icon, and has a lot of great features. It's kind of a "must have" for and Mac Power User.
There's an app (in the Mac App Store) that lets you name Spaces via the menubar. It also lets you give each Space a unique icon, and tells you how you spend time across your Spaces (and the apps within them). Because macOS APIs are limited, the names stay in the app and don't show up in Mission Control. But they are persistent.
The app also lets you jump ...
