I’m download the lastest version of Delphi 11.1 and all is Ok, but when I try to debug project in MAC Monterey 12.3.1 using PAServer 22, I have an error in PAServer Terminal window, it said that Framework Python can’t be found in System/library/Frameworks/.., I install Python 2.7 but it’s not installed in System/... is installed in Library/... and PaServer can’t find it. Have you any Solutions for that problem?

Thank you.

    I notice the [requirements](https://docwiki.embarcadero.com/RADStudio/Alexandria/en/Running_the_Platform_Assistant_on_a_Mac#M1_Debugging) say: The PAServer uses LLDB on macOS 64-bit (ARM), which requires Python 3.9. – Brian Apr 20 '22 at 19:20

    The problem is with macOS 64-bits(x86_64) and with (ARM), the problem is in dinamic librarys that use PAServer that have inside fixed references to /System/Library/Frameworks/... of Python 2.7 Framework and in MAC Monterey this path not exits. If you install Python 2.7 the Framework is installed in /Library/Frameworks/... . – IndexCons Apr 21 '22 at 12:30

At this time, this is a known issue. See https://quality.embarcadero.com/browse/RSP-37609 for more details. Sadly there is no official fix yet. But in that RSP you will find a workaround by Michael Geddes that might help you:

For those that want to get going no matter what, I suspect this will work (haven't tried it yet, and it will probably not survive an update):

Install Python 2.7 package from python.org
Disable SIP
    Reboot Mac hold down Command + R
    From a shell:
        > csrutil disable
        > reboot
Remount / as read-write
    > sudo mount -uw /
Check that /System/Library/Frameworks doesn't exist and then Copy (?link) in the Python framework.
    > cp -R /Library/Frameworks/Python.framework /System/Library/Frameworks
Enable SIP
    Reboot Mac, hold down Command + R
    From a shell:
        > csrutil enable
        > reboot

  • Thank you, it can be a solution, I try ... – IndexCons Apr 25 '22 at 12:53
  • Meanwhile a patch has been released for 11.1. And guess what? It does not fix the problem, merely issues a workaround similar to this. https://blogs.embarcadero.com/rad-studio-11-1-alexandria-patch-1-available/ – Sherlock70 Apr 28 '22 at 10:21
  • the solution isn't valid, Monterey have the root folder like a Virtual foolder and encrypted, it's impossible change the folder. – IndexCons Apr 28 '22 at 17:04
  • The good solution is recompile PAServer librarys to find Python in /library/Frameworks/.. folder, the problem is that my subscription to embarcadero is down and I can't download new PAServer. :-( – IndexCons Apr 28 '22 at 17:45

Finally I have the solution, use:

sudo install_name_tool -change '/System/Library/Frameworks/Python.framework/Versions/2.7/Python' /Library/Frameworks/Python.framework/Versions/2.7/Python liblldb.3.8.0.dylib

I change the dylib that crash, with new path for Python.

  • It probably works judging from a description of how install_name_tool works that I found at https://stackoverflow.com/a/9263735/903783 – George Birbilis May 19 '22 at 10:23
  • ...however when you run it (having installed Python 2.7.8 from https://www.python.org/ftp/python/2.7.18/python-2.7.18-macosx10.9.pkg) it says "can't open file: liblldb.3.8.0.dylib (No such file or directory)" – George Birbilis May 19 '22 at 10:37

I was having the same issue, followed the link posted by Sherlock70 to the link posted (https://quality.embarcadero.com/browse/RSP-37609)

I saw part way down in the comments that Marco Cantu posted saying the patch was available and had this link on his post https://blogs.embarcadero.com/rad-studio-11-1-alexandria-patch-1-available/

Once I ran the RadStudio 11.1 patch, I copied the new PAServer 22.0 over to my Mac and followed the "Additional Steps for Python Configuration on macOS" that Marco has in his post above.

Once I did that, everything is able to run on my iPad running iOS 15.4.1 now

I've followed the steps in the linked Embo blog. Using Montery. It still returns the error about not being able to find the System/Library/Frameworks/Python.framework/Versions/2.7/Python path etc. Stupid thing was working yesterday.

Have just reinstalled Delphi 11.1 and the two patches on GetIt (so version is now Embarcadero® Delphi 11 Version 28.0.44500.8973)

Installed Python 2.7 on the Mac and ran the 3 commands in the terminal.

This is beyond frustrating ....

  • Finally got it to work. Had to reinstall PAServer, aand then re run the 3 command lines ... Be warned, follow the steps exactly: – David Moorhouse Jul 01 '22 at 02:32
