Why does every Bluetooth device in Android have "contact sharing" toggled on? I can't even find a useful description of what the setting is supposed to be for. I mean, my keyboard and headset shouldn't need this, right?

Contact sharing transfers your contacts list to a Bluetooth device such as a car's infotainment system, so you can use that device's user interface for hands-free calling. I don't know why it would default to "on."

I *think* that this functionality is for syncing your phone's phone book to, for instance, your car's stereo.  But it seems odd that it should be available to your keyboard, for sure.

Just checked my phone (an LG v50) and contact sharing is enabled for all my Bluetooth devices as well.

I know System Integrity Protection is a good feature, but sometimes it's just annoying as fuck.  I'm trying to delete an old backup of my system folder and I just can't because there's an SIP lock on the Siri voice trigger at ~/Library/VoiceTrigger/SAT.  Not even root can delete it.  I'm going to have to reboot into Recovery mode, disable SIP, delete it, then reenable SIP.  Ugh.

No, SIP lock does not completely prevent use of superuser. Did you try sudo rm -r from a Terminal? It has to be recursive for directories. Or maybe it's just su to open the superuser shell, in which case there is no sudo command. It should work. Definitely for ~/Libary, unless there are permissions shenanigans on that sub-directory. In which case you need rm -rf. Sudo use the force force delete. (https://manik.me/2017/05/26/add-user-sudoers-file-mac-os-x/)

No, sudo rm -rf does not work. Nor can one chmod, chown, touch or even ls the file in question. Chmod and chown result in errors saying that the ACL could not be modified.  If one opens Get Info on the file, the More Info... tab has a spinning wheel and under permissions it says, "You have unknown permissions."  I was able to move the file to Trash, but it can't be emptied with it in there.

A search online finds others who have had the same issue when trying to delete a home folder manually.  They say that turning of SIP works.  I'll let you know how I fare.

ETA: Worked a charm.  Couldn't delete it even in recovery mode until SIP was disabled. Once disabled, no problems.

If you boot into recovery firmware (Mac+R), you get a superuser Terminal. I know that hasn't changed.  ;) That's where you have to go to turn SIP on & off anyways.

I know that.  But that superuser still can't delete that file with SIP turned on.

Are you sure don't mean a folder in the system library folder (/Library)?

You did mention deleting a user's home folder, so you do mean a file In /Users/*/Library/ ? If so, it could be a filesystem bug, or a bug where a program changed permissions on a file/directory in there. What kind of library sub-folder is it?

I already explained exactly what file was at issue here.

In other news, when our firewall rejects an expired certificate on an active directory server, it logs the event as "unable to connect to LDAP server." No mention of a TLS error, much less an expired certificate.  I was finally able to track it down in the logs on the AD server...after spending far too long troubleshooting the actual connection.  Seems it sent an expired certificate code back to the AD server, but didn't bother logging that code itself.  Arrgh.

Also, I've said it before but it bears repeating: fuck certificates.

Sit down to finally watch Midsommar. Dust filter warning pops up on projector. "Clean dust filter!". Check filter info: 1000h passed (yes, I watch too much TV), which is the default time for the reminder. No way to get rid of warning, it remains on screen indefinitely, and it's a giant overlay across my entire screen. Turn projector on and off. Starts up slower than usual because of course it does. Warning still there. Reset filter hours via menu. Warning remains. Turn of reminder entirely. Warning remains. Finally decide to just clean it then if it's so damn important that it has to happen this exact moment. Take out filter holder: There is no fucking filter in there at all!



Turn projector back on, everything seems normal now.
Mooohn!
