I want to uninstall Python 3.13 and only keep 3.9. I tried using brew but just get this error:

brew uninstall python@3.13
Error: No such keg: /opt/homebrew/Cellar/python@3.13

I don't have admin permissions to manually delete the files in /Library:

which python3.13
/Library/Frameworks/Python.framework/Versions/3.13/bin/python3.13

How can I actually remove this version? Running the following command shows python is located in /Library but I can't remove it due to not having sudo access.

type python3
python3 is /Library/Frameworks/Python.framework/Versions/3.13/bin/python3

I am developing a Python software and I'd like to generate a logs folder where .log files can populate for user-debug. When I run the file through the main init. and the .app created by PyInstaller, the logs folder generates just fine. But when I test the app distribution (creating a .dmg), the .app gets flagged by Gatekeeper. I can open it through Settings>Privacy & Security, but my logs file won't generate (due to com.apple.quarantine attribute). Anyone have a recommended workaround to give my software writing ability? I'd prefer not to pay the developer subscription...Thanks!

I need to install python3.4 on my OS X. Tried to do it with brew install python3 and now I have python 3.5.1. But I need py3.4. How can I install python3.4 on my Mac?

On my Windows machine, I ran pip3 install scikit-learn and it installed without any problems, however, on my Mac, I've tried a lot of things:

I've also tried the commands on the official website, https://scikit-learn.org/stable/install.html , which produce similar errors as my system doesn't recognize pip and the -U flag doesn't make a difference. What am I doing wrong?

I ran through a few upgrades of homebrew, in the past, and all python scripts I used to use were running fine, post python updates, meaning the upgrades got all necessary site-packages properly accounted for. Today my luck ended using the same mechanism: brew update && brew upgrade && brew cleanup --prune=all), and I see my new python version at 3.12.2 having replaced my previous 3.11, but missing tons of stuff in /usr/local/lib/python3.12/site-packages (as compared to 3.11). Some of them are the praw ones, thus the obvious "No module named 'praw'" when trying to run a python script dependent on it. I do recall having had a similar issue, a while ago, which I thought I fixed with some simple pip install --upgrade praw or python -m pip install --upgrade praw, but these are now coming back with the "error: externally-managed-environment". Any ideas how I could fix this?

There are twelve executables named python on my intel macbook pro.  None of them are in my path, but "python3" in my path points to version 3.13.4 installed by homebrew. When I try python3 -m pip install pinyin I get two screens of diagnostics, starting with × This environment is externally managed ╰─> To install Python packages system-wide, try brew install xyz, where xyz is the package you are trying to install. but brew install pip says there is no formula for pip. I need to run a python script that starts with import sys import re import pinyin but it errs with a complaint about pinyin on line 3 I also tried doing it with the Apple-installed P{ython, but no success there either. Advice? Update: After studying those two screens of diagnostics, it seemed to advise me to install and use pipx instead.  So I did that, and then pipx install pinyin said pinyin is already installed!  So I tried running the intended command again and got the same complaint: WGroleau@MacBookPro pinyin % python3 convert_pinyin.py test.pinyin.php test.pinyin.php Traceback (most recent call last): File "/Users/WGroleau/ChiCal/pinyin/convert_pinyin.py", line 3, in import pinyin ModuleNotFoundError: No module named 'pinyin' WGroleau@MacBookPro pinyin %

I am trying to use mss to capture a portion of my screen using the following code:

When running, my mac keeps prompting for permission and I have to click allow for every request. Unfortunately, this isn't just a one-time thing, it happens for every screenshot request I make. This is not feasible when I am making multiple requests. Hence, I am looking for a way to disable this security check. I have allowed terminal full access to the disk, and to screen and audio recording in my system settings. This still didn't work so I am currently using pyautogui to automatically allow this, but this is still slow (takes ~0.2 seconds to get rid of) for my application. I am expecting a solution to guide me to disable the above security check. Is it possible to eliminate further requests? edit: output of the given command (

I'm fairly new to MacOS, when i try to directly do

pip install

the terminal whether in VScode or the normal mac terminal gives the output as

But if i execute the same command after activating my virtual environment, it works. can anyone help in explaining this.

I've built a simple Python script that tries to discover my Sonos speakers via mDNS/UPnP/Bonjour and set some music sources to them. This is done using the [soco](https://soco.readthedocs.io/en/latest/getting_started.html) lib. The script works well when started on the shell. Starting it from a LaunchAgent (same machine, same user), it can't find the speakers.

I'm a bit puzzled as of why it doesn't seem to get network access when run via LaunchAgent. I've even extended the discovery timeout to 30 seconds. System is macOS 15 Sequoia. Caveat: The Mac is connected to multiple networks using VLANs.

My program works as follows In a while loop, it checks for the active window change - AppKit library used from AppKit import NSWorkspace active_window = (NSWorkspace.sharedWorkspace().activeApplication()['NSApplicationName']) if the active window changes to from some other window to google chrome, I need get the url from the chrome's current tab using apple script as : url="""tell application "System Events" tell application "Google Chrome" to get the URL of the active tab of window 1 as string end tell""" This script is running fine, I can able to get the current window name and also url I need to know which kind of identifier, provisioning profile, certificate should be used for the same Im confused of choosing the certificate I don't have any idea if I need to have a provisioning profile Im not going to place this app in mac app store, I just wanted to use this app to support another electron application Any help is appreciated

I've looked around *a lot* to try to find the answer to this but have thus far been unsuccessful. I am programming in Python, and I have code that takes a long time to run (hours to months depending on the application) and I am trying to optimize it. On larger thread systems (once I get above ≈8 threads, but especially >18 threads), I run into a situation where the system is using up a large amount of my CPU instead of the actual code I want to run. On a 12-thread machine as I type this, the system is using ≈25–30% of my total CPU. If I try to run it on a 36-thread machine, the system takes >70% of the CPU which is simply unworkable (though running two instances of the code, limiting each to 18 threads, cuts this overhead back, oddly enough). The Activity Monitor indicates that

is using at least 10%, while

,

, and

are also using several percent, each (along with

at 1% so I should turn off Spotlight, and sometimes

spikes to >40%, but that's more rare ... note that that process is another launch system daemon). My older hypothesis was that it was a disk I/O issue, since the code was writing and reading many small files to try to keep track of certain things and recover if I needed to stop it. My now-working hypothesis, based on what I could find online about the interactions between

and

, is that this particular chunk of code is spawning a large number of processes and macOS's launching and security daemons are taking large amounts of CPU to make sure those processes are safe. These are things like calling "mv" and "rm" from the command line (os.system(...) in my Python code), and spawning other code that take a second or two to run (such as in a different conda environment when two have conflicting installs of necessary components). I count at least 40 potential spots where this chunk of code is possibly spawning child processes, and I thread it so that it's doing that concurrently however many threads there are (so, on a 12-thread machine, 12x40 over the course of ~10 seconds). It doesn't seem to me like this should be making my system take up so much CPU, but that's my best guess at the moment. Possibly related, the

is constantly spitting out to log files, "MacOS error: -67062", which again I've searched for and found no luck with diagnosing the issue. And,

is spawning a lot of "\\" messages in the Console, but its CPU% is around 0.3% so I'm less concerned about that. My apologies for rambling a bit here, but I'm trying to provide the information I have, and hopefully someone here has an idea. If I can get rid of this 25% or larger issue, that can save months of time. For what it's worth, I'm running macOS 10.14.5 and ..4 on two desktops, and 10.15.5 on a laptop. Same issue for all. Running in Linux on a nearly identical 36-thread system build does not have the overhead issue (but I really don't want to switch to Linux) which is another reason why I don't think it's a disk I/O problem.

My python installation was messed up after I ran the command brew install curl causing Homebrew to auto update. Since then, I discovered that matplotlib was not installed (it was before the update), which I had to install with brew and not pip, and whenever I import the newly installed matlplotlib.pyplot, there is an error regarding not finding PIL. Installing Pillow does not have any effect on this error. Is there a way to reverse that to when everything worked well on my Mac? I am running macOS Sonoma 14.5. Any help is welcome. Thanks!

The numeric keypad on my Magic Keyboard does not work when I am running the Python interpreter in interactive mode. The regular numbered keys do work for entering numbers. But when I try to enter a number on the numeric keypad when I am running the Python interpreter (launched from the Terminal) I get no response. Also, the numeric keypad on my Magic Keyboard DOES work properly when I am using other apps, including, but not limited to, TextEdit, Numbers, irb (the interpreter for the Ruby language), Terminal (when I am not in the Python interpreter), and every other app that I have tried. I am now running Python 3.13.2

[I initially thought that this would happen with Catalina](https://apple.stackexchange.com/q/361840/321512) , but since it didn't happen, a similar question is again relevant: My question is two fold: - **When I eventually update to macOS Big Sur, will the Python (2.7.X) installation – which currently ships with macOS – get removed from my system?** - **What about if I do a fresh install; will python be gone then?** Relevant section from macOS Catalina 10.15 Release Notes (emphasis mine): >## Scripting Language Runtimes >### Deprecations > - Scripting language runtimes such as Python, Ruby, and Perl are included in macOS for compatibility with legacy software. Future versions of macOS won’t include scripting language runtimes by default, and might require you to install additional packages. If your software depends on scripting languages, it’s recommended that you bundle the runtime within the app. (49764202) > - Use of Python 2.7 isn’t recommended as this version is included in macOS for compatibility with legacy software. **Future versions of macOS won’t include Python 2.7.** Instead, it’s recommended that you run python3 from within Terminal. (51097165) > > Source: https://developer.apple.com/documentation/macos-release-notes/macos-catalina-10_15-release-notes I can't find anything about this in [Big Sur's release notes](https://developer.apple.com/documentation/macos-release-notes/macos-big-sur-11_0_1-release-notes) though. Edit: I am not actively using Python 2, I'm simply wondering this since it might affect some 3rd party software which relies on the OS's Python installation.

I'm having a problem using the int() function on a user input from the keyboard in Python 3 (latest version from website). The actual program will perform various numerical calculations, but I have written a short test program that shows the problem. The int() function works fine for values embedded in the code, but crashes if the same number/format is entered via the keyboard. 1. dummy_num = (2.5) #just an example float number 2. dummy_num = int(dummy_num) #converts 2.5 to integer 2 3. print (f"{dummy_num}") #verifies result of "2" 4. variable_test = input ("type 2.5 please:") 5. print (f"{variable_test}") #verifies 2.5 is actually entered 6. variable_test = int(variable_test) The program runs as expected for lines 1 to 5. If 2.5 is entered via the keyboard in line 4, line 5 prints 2.5, but then line 6 crashes the program. An error message is generated as follows: variable_test = int(variable_test) ValueError: invalid literal for int() with base 10: '2.5' I don't understand why the int() function works fine for the value "2.5" in line 2, but crashes in line 6 - even though line 5 shows that the number entered is indeed 2.5 and the same program instruction works fine in line 2. Sorry if this is a newbie error, but I have run out of ideas. Note that I put a few #comments in the above code just for the purpose of this question.

I'm on macOS Sequoia 15.3.2, and I've been experiencing some weird behavior with /usr/bin/python3 lately. Usually it seems like a perfectly normal Python 3.9 binary:

Python 3.9.6

But then when I cd into a directory with [use flake](https://github.com/nix-community/nix-direnv) in its [.envrc](https://direnv.net/) file, it suddenly starts pretending like it doesn't exist:

But the _file_ does exist:

**What is in /usr/bin/python3 on macOS?** What kind of binary is it, and why does it print this bizarre "tool 'python3' not found" error message in some situations?

I am in the process of writing a small Python Script to automate sending some emails that I send every week, specifically every Monday at 8 AM. The Python script calculates when the next Monday will be, fills in the email template with the specific information, and then schedules it. I have been able to get the AppleScript to create the email, put in the recipient, and put the signature, but I have not been able to get it to click on the schedule to send email button and schedule it for 8 AM. Here is the current AppleScript I have:

tell application "Mail"
        set theSender to "{sender_email}"
        set newMessage to make new outgoing message with properties {{subject:"Interest in {position} at {company}", content:"{email_body}", visible:true}}
        tell newMessage
            make new to recipient at end of to recipients with properties {{address:"{recipient_email}"}}
            set sender to theSender
        end tell
    end tell

    tell application "System Events"
        tell process "Mail"
            set frontmost to true
            tell window "Interest in {position} at {company}"
                click pop up button "Signature:"
                delay 0.5
                click menu item "AccountName" of menu of pop up button "Signature:"
                
                -- Wait for UI to update
                delay 1
            end tell
            
            -- Access the menu directly through menu bar item name
            -- This uses exact menu hierarchy: Message menu > Send Later...
            tell menu bar 1
                tell menu bar item "Message"
                    tell menu "Message"
                        click menu item "Send Later..."
                    end tell
                end tell
            end tell
            delay 1
            
            -- In the schedule dialog that appears
            tell sheet 1 of window "Interest in {position} at {company}"
                set value of text field 1 to "{next_monday_formatted}"
                set value of text field 2 to "8:00 AM"
                click button "Schedule"
            end tell
        end tell
    end tell

Everything works but the scheduling part, and this is the last attempt I have made. I know that there are email automation tools, but I want to learn how to code this by myself and integrate it into the terminal. Any help would be appreciated, thanks!

I am using Jorrick's MacOS notifications generator to make custom popup notifications. Whenever one appears, it uses the Python Launcher rocketship icon, like this: I want to replace the rocketship image with the System Settings gear icon. So, I followed Apple Insider's tutorial on how to do so, and succeeded. This method only works with images, not .icns files - maybe there's a lead there. I also deleted PythonLauncher.icns, the picture of the rocketship, made a .icns of the gear, and put it in the same directory with the same name, so hopefully the program would use that as the icon. Now, PythonLauncher.app uses the gear icon in several places, but annoyingly, still not the notification icon! 1. The Python I'm executing to make the notification. I run it with python3 notifgen.py from Terminal. 2. The gear.png icon is used in the Get Info window 3. The gear.png icon is used in Finder 4. The gear.png icon is used in the Dock 5. The .icns file I made to replace the rocketship. Changing this file does not change the previous three icons. 6. The notification, still using the rocketship icon, even though that icon does not exist anywhere on my system. I deleted all traces of it. To be sure I deleted all copies of the old rocketship icon, I ran sudo find / -iname '*PythonLauncher*' 2>/dev/null | tee ~/Documents/python/pythonlaunchersearch.txt. The ouput of that command is below - I added newlines and explanatory comments, and opened each file in Finder to check what it was.

I could never be a detective, because I can't find where this rocketship icon is hiding. **How is Python still accessing the rocketship icon, even when it no longer exists? And how can I change the icon to be the System Settings gear instead?** Sharing an alternative to Jorrick's package that does allow to change the icon would also be a great answer. Postnote: The commented icon variable in the python program isn't helpful - that puts a small icon in the bottom right, like this:

I asked over on Stack Overflow, but this seems a problem specific to Mac OS X as the error does not happen on other OS (ubuntu for example). https://stackoverflow.com/q/42637680/447830 repeated below: So.

I have a weird issue with Python on macOS Sequoia for the last couple of days. It did not happen right after the upgrade, it worked initially. Python in Terminal.app cannot resolve any DNS queries. However, the Python console and the builtin Terminal in PyCharm works just fine. Here's a sample; the http command is [HTTPie](http://httpie.io) , a Python based utility:

% http google.com

As you can see, network connections in general are fine, only DNS queries can't be resolved. They time out after about 30 seconds. However, the same within PyCharm works fine. I've read about HTTP_PROXY environment variables maybe being a problem, but I don't have those set. I don't know enough about DNS resolution and how Python uses it to even know where to look. Any ideas?
