I have resurrected a C++ project I was working on a few years ago in Qt (MacOS), and can no longer get debugging to work. The problem seems to be that it is trying to use the wrong (old?) version of LLDB. The current macOS version is 12.6.8. I'm not sure what the version was when I set it all up. In Preferences > Kits > Debuggers, it lists as 'Auto-detected' both Applications/Xcode.app/Contents/Developer/usr/bin/lldb, and /usr/bin/lldb. The latter is flagged (popup appears when hovering) as 'Cannot determine debugger type' (and with a red warning marker). The other entry seems fine. When I look in Projects > Build and Run and hover over Build (for this project) the popup window tells me 'Not recognised engine using /usr/bin/lldb', and when I try to run the code in debug mode I get the message (in Application output) 'Unable to create a debugging engine'. It seems that Qt is finding two versions of the debugging engine, one of which is presumably OK and the other not, and then tries to use the wrong one. There is no option in the list of debuggers in Preference > Kits to remove the problematic one or to set a default. How can I figure out these dependencies to get my project to compile?

I am currently using a Docker container that requires squashfs to create the file system. The container fails to start up correctly and displays this in the logs: 2024-02-01 08:09:53 mount: /mnt/sqfs: unknown filesystem type 'squashfs'. To debug, I ran cat /proc/filesystems in the docker container and it did not list squashfs. I saw in [the release notes for version 4.27.0 of docker](https://docs.docker.com/desktop/release-notes/#for-all-platforms) (latest as of this question's writing): > Bug fixes and enhancements > > For all platforms: > - [...] > - Re-added kernel modules for btrfs, xfs, vfat, exfat, ntfs3, f2fs, **squashfs**, udf, 9p and autofs. I learned from [this Stack Overflow thread](https://stackoverflow.com/questions/54913641/enabling-squashfs-inside-docker) that > A Docker container cannot have a different filesystem list than their host machine so I assumed my mac was missing squashfs. I then [installed squashfs with homebrew per this thread](https://apple.stackexchange.com/q/212906/331689) but it still doesn't work. Even after restarting docker, running cat /proc/filesystems in the docker container STILL does not list squashfs. It still also shows the error above as well. How can I run a container requiring squashfs on an Intel Based Mac running Sonoma 14.3 and Docker Desktop for mac? ---------- **EDIT:** Please Note, Versions **4.27.0** and **4.27.1** of Docker for mac [have a known issue where docker crashes a few minutes after boot](https://github.com/docker/for-mac/issues/7164) . Beware if you are planning on installing these versions of docker. ---------- **EDIT 2:** Versions **4.27.2** of Docker for mac has fixed the errors in versinos **4.27.0** and **4.27.1**. After installing it, I now see squashfs listed when I run cat /proc/filesystems in the docker container. My docker container still doesn't run properly though, and I now get a different error in my docker logs: 2024-02-13 11:54:40 mount: /mnt/sqfs: wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error.

I'm looking for a free way to do AI-powered "text to speech", so I can copy-paste an article or document and have it read to me. I've tried say on the command line, but the lack of AI means it is much harder to comprehend. All of the non-AI TTS-libraries that I've found are also much harder to comprehend than the new generation of AI-powered TTS. Specifically, the new AI-powered TTS services seem to understand some of the meaning and structure of the sentence that is being read, and so they provide better natural cadence. This alleviates stress on the listener to parse the meaning of what is being read out. All of the apps I've come across so far have tried to get me to sign up for services that cost well in excess of $100 per year. My best alternative at the moment is to write my own code to use an API such as the Google Cloud text-to-speech API, but even that will cost me around $0.12 to speak a typical 1300-word article. Perhaps there is some kind of open-source software that works on Mac Silicon, that I can install to generate better speech from text?

I noticed dupeguru webpage last has updates in 2018 and when opening the app, Ventura says it could be malicious software and the developer should update. I saw activity on GitHub, however not sure if anyone has compiled this from source. Does anyone know of this works on macOS Ventura?

    If you wish to install a Python application that isn't in Homebrew,

    You may restore the old behavior of pip by passing
    the '--break-system-packages' flag to pip, or by adding
    'break-system-packages = true' to your pip.conf file. The latter
    will permanently disable this error.
    
    If you disable this error, we STRONGLY recommend that you additionally
    pass the '--user' flag to pip, or set 'user = true' in your pip.conf

I have encountered a situation in rsync where --delete does not work *but* `--delete-after` seemingly does. See the screen shot below that shows the two commands one right after the other. Deleting test.txt is the expected result that only works with --delete-after. (And for some reason it's not working today but has worked fine before.) Is this an rsync issue specific to the Mac? This is on Sequoia 15.1 using rsync version 2.6.9.

sh

**Update to initial post with answer** Here's an example (with help from ChatGPT) that provides an example: mkdir -p test/source test/dest touch test/source/file1 touch test/dest/file1 test/dest/file2 # file2 should be deleted with --delete rsync -av --delete test/source/ test/dest/ This does delete file2, as intended. The issue is that there isn't any "verbose" output indicating that file2 is being deleted, even though -v is being used. Interestingly when you use --delete-after, it does show that file2 is being deleted. The solution is to use the -i flag and this does show file2 being deleted more explicitly. Without -i: rsync -av --delete test/source/ test/dest/ Transfer starting: 2 files In contrast with -i rsync -avi --delete test/source/ test/dest/ building file list ... done *deleting file2 .d..t.... ./ So the question becomes: why does -v work the way I expect it to with --delete-after but not with -delete. Is this related to Sequoia using a different version of rsync? See also https://apple.stackexchange.com/questions/479291/shell-scripts-that-call-rsync-no-longer-work-in-macos-sequoia

I'm noticing on macOS v13.7 BSD tar files have unexpected contents when unpacking on GNU Linux. For GNU compatibility I need to use tar --disable-copyfile --no-xattrs, otherwise I end up with this issues untiring on a GNU system: tar: Ignoring unknown extended header keyword 'LIBARCHIVE.xattr.com.apple.metadata:kMDItemTextContentLanguage' ... Duplicate files F prefixed ._F in the tar file. I see following workaround posted here and here , however no explanation why macOS tar needs to behave this way. Does anyone know why macOS tar is behaving this way?

I've recently switched from Hyper terminal (no longer maintained) to iterm2. I'm surprised that iterm2 seems to be using vi mode: instead of going to start and end of line when I press ctrl+a/ctrl+e it emits literal ^A and ^E. I don't remember ever configuring vi mode on purpose. iterm2's configuration GUI overwhelms me. I've tested running zsh in factory mode (zsh -f), and even there iterm2 uses vi mode. In contrast, when I use Hyper or the inbuilt terminal, zsh is in default readline mode. How can I fix this? I've gone through iterm2 documentation and issue tracker and couldn't find anything. Interestingly, when I run zsh -f in inbuilt Terminal, it _is_ in vi mode. Similar question over at superuser, which has been open for 10 years without answer: https://superuser.com/questions/840134/unintentional-vi-mode-in-iterm-on-mac

I'm using shortcut to input and append info to a note document. The issue is that I'm trying to escape all the quotes and apostrophes in my inputs, but some might already be escaped so I have to do so selectively. The command I made for this in shortcuts was `Replace (? Hello there it's me, don\\'t escape this one. "One quote" followed by \\"another\\" > > Testing new date format and some escape characters like " and it's Which then becomes > Hello there it\\'s me, don\\'t escape this one. \\"One quote\\" followed by \\"another\\" > > Testing new date format and some escape characters like " and it's So for whatever reason it isn't replacing anything on the second line with the escaped versions. I built this regex over at https://regexr.com/ where it matches all the strings in the input I give so it should work as far as I can tell, and it's not like the negative look behind isn't supported since it works fine in the first line. I also tried adding a separate " ' after the second line to see if it'd get escaped and those ones did, but the ones already in that line didn't. Can anyone offer an explanation so I can better understand what's going on with the expression I chose and the data I’m feeding it?

I have MSMTP running flawlessly on four Raspberry Pies. I use it to send email from shell scripts. It works fine as a SMTP client. I installed MSMTP and mailutils on an M1 iMac via MacPorts. I configured MSMTP as follows using the information here: msmtp_gmail_setup /etc/mail.rc:

set append dot save ask crt
ignore Received Message-Id Resent-Message-Id Status Mail-From Return-Path Via
set sendmail=/opt/local/bin/msmtp

The only thing I added was the "set sendmail" line. .msmtprc looks like this:

# Generics
defaults
auth           on
tls            on
# tls_starttls   on
# following is different from ssmtp:
# tls_trust_file /etc/ssl/certs/ca-certificates.crt
# user specific log location, otherwise use /var/log/msmtp.log, however,
# this will create an access violation if you are user pi, and have not changes the access
rights

tls_fingerprint 7D:8B:CD:37

logfile  ~/.msmtp.log

# my  specifics
account        gmail
auth           plain
host           smtp.gmail.com

from           me@gmail.com
user           me
password       my_password

# Default
account default : gmail

If I run the mail command on the command line it lets me address and compose a message, but I get the following error:

msmtp: no recipients found
Sending data to /opt/local/bin/msmtp failed: Process exited with a non-zero status
cannot send message: Process exited with a non-zero status

There are no entries in ~/.msmtp.log What have I done wrong here?

I'm a bit confused. I've installed a bunch of libraries (e.g. vtk, gsl,...) that I need for a c++ project for school. I used homebrew to install them (luckily there were formulas available). My question is, does Homebrew link these into /usr/include or something comparable? Or is this something I would need to do manually? Homebrew usually does this kind of stuff for executables, yet I can't seem the find the libraries anywhere other than in the /usr/local/Cellar/... directories. I have a bunch of libraries installed so I can't simply use -L/... for each of them.

Is it possible to and how do I get a list of all the packages installed on my Mac using Homebrew? I am not interested in packages installed outside of Homebrew.

How can I prevent the Mac v13.7.3 DHCP server from sending traffic to network interfaces? I.e. how can I manage this? I'm trying to invoke dnsmasq and another application is using port 67 socket. I also notice the VirtualBox clients are getting DHCP addresses on the "HostOnly" network. I see this launchd is using the port: sudo lsof -i :67 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME launchd 1 root 29u IPv4 0x60ac5cc81221ae9f 0t0 UDP *:67 launchd 1 root 39u IPv4 0x60ac5cc81221ae9f 0t0 UDP *:67 From this question and answer I put together that launchd may be invoking the DHCP server. I tried to edit /private/etc/bootpd.plist in the section to disable the dhcp server: dhcp_enabled and reload as follows, however I get errors: $ sudo /bin/launchctl unload system/bootpd.plist Unload failed: 5: Input/output error I try the following suggestion, however the port is still being used: $ sudo launchctl unload -w /System/Library/LaunchDaemons/bootps.plist $ sudo launchctl load -w /System/Library/LaunchDaemons/bootps.plist $ sudo lsof -nP -i:67 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME launchd 1 root 39u IPv4 0x60ac5cc8052e1e9f 0t0 UDP *:67 launchd 1 root 41u IPv4 0x60ac5cc8052e1e9f 0t0 UDP *:67 $ sudo launchctl stop -w /System/Library/LaunchDaemons/bootps.plist Exit status: 3 I didn't expect VBox clients to be receiving DHCP datagrams because nothing is checked in the GUI and the VBoxManage command line tool doesn't show any DHCP server active.

I am trying to run Midnight Commander on my Mac and am getting a malware message saying that it was moved to trash and that it didn't affect my computer. I have tried removing it and reinstalling it but still get the same message.

I am using msmtp as a mail client on an M1 iMac still running Monterey. I use Gmail as a relay. It's been working fine, except recently I started getting the following error message:

send-mail: TLS certificate verification failed: the certificate fingerprint does not match

So, I generate a new fingerprint with this:

msmtp --serverinfo --tls --tls-certcheck=off --host=smtp.gmail.com --port=587 | egrep -o "([0-9A-Za-z]{2}:){31}[0-9A-Za-z]{2}"

And then it works, until it doesn't. In the last couple of days I've had to generate three new fingerprints. Why do the fingerprints seem to expire and is there anything I can do about it?

It would make it easier to determine which formulae are the most useful, and to discover new software I may not have heard of. Currently, I just use homebrew when I find out "I need to install this" for some dependency. Is there a way to determine which Homebrew packages have been installed the most times, either in the recent past or all-time?

I've noticed that when I run : brew update Homebrew was connecting to Google analytics and now warns about InnoDB anonymous analytics one time. Why and how to opt out?
