The trust certificates in system and user keychains managed by the 17\f2\i Keychain Access 18\f0\i0 application and the 19\f2\i security 20\f0\i0 command line utility are not used as defaults by the Python 21\f3 ssl 22\f0 module. A sample command script is included in 23\f3 /Applications/Python 3.10 24\f0 to install a curated bundle of default root certificates from the third-party 25\f3 certifi 26\f0 package ({\field{\*\fldinst{HYPERLINK "https://pypi.org/project/certifi/"}}{\fldrslt https://pypi.org/project/certifi/}}). Double-click on 27\f3 Install Certificates 28\f0 to run it.\ 29\ 30The bundled 31\f3 pip 32\f0 has its own default certificate store for verifying download connections.\ 33\ 34 35\f1\b \ul Install Options\ 36 37\f0\b0 \ulnone \ 38You can control some aspects of what is installed by this package. To see the options, click on the 39\f4 Customize 40\f0 button in the 41\f4 Installation Type 42\f0 step of the macOS installer app. Click on a package name in the list shown to see more information about that option,\ 43 \ 44 45\f1\b \ul Using IDLE or other Tk applications 46\f0\b0 \ulnone \ 47\ 48This package includes its own private version of Tcl/Tk 8.6. It does not use any system-supplied or third-party supplied versions of Tcl/Tk.\ 49\ 50Due to new security checks on macOS 10.15 Catalina, when launching IDLE macOS may open a window with a message 51\f1\b "Python" would like to access files in your Documents folder 52\f0\b0 . This is normal as IDLE uses your 53\f1\b Documents 54\f0\b0 folder as its default when opening and saving files; you can still choose other locations in the 55\f1\b Open 56\f0\b0 and 57\f1\b Save 58\f0\b0 file dialog windows. Click on the 59\f1\b OK 60\f0\b0 button to proceed.\ 61\ 62 63\f1\b \ul macOS 11 (Big Sur) and Apple Silicon Mac support\ 64 65\f0\b0 \ulnone \ 66For Python 3.10 releases, we provide a new 67\f4 universal2 68\f0 installer variant that provides universal binaries for both 69\f4 ARM64 70\f0 and 71\f4 Intel 64 72\f0 architectures and is also supported on all Macs that support macOS 10.9 or later. Some of the advantages of the new installer variant: native ARM64 code on Apple Silicon Macs should run significantly faster than Rosetta2-emulated code; some operating system functions and options introduced in macOS releases since 10.9 are now exposed when available (primarily in the os module); and the new installer variant includes Tcl/Tk 8.6.11 rather than 8.6.8.\ 73\ 74On Apple Silicon Macs, it is possible to run Python either with native ARM64 code or under Intel 64 emulation using Rosetta2. This option might be useful for testing or if binary wheels are not yet available with native ARM64 binaries. To easily force Python to run in emulation mode, invoke it from a command line shell with the 75\f4 python3-intel64 76\f0 command instead of just 77\f4 python3 78\f0 .\ 79 80\f1\b \ul \ 81Other changes\ 82 83\f0\b0 \ulnone \ 84For other changes in this release, see the 85\f2\i What's new 86\f0\i0 section in the {\field{\*\fldinst{HYPERLINK "https://www.python.org/doc/"}}{\fldrslt Documentation Set}} for this release and its 87\f2\i Release Notes 88\f0\i0 link at {\field{\*\fldinst{HYPERLINK "https://www.python.org/downloads/"}}{\fldrslt https://www.python.org/downloads/}}.\ 89}
