iTunes 12.9.5: is there any alternative to disabling SIP? Reason being, it breaks all your iOS apps: they won't open. [Retroactive 2.0, Monterey 12.6 (M1)]

Just noticed this myself. You have to re-enable it for them to work again, and that breaks iTunes 12.9.5 again :(

I managed to get 12.8.3.1 working with scripts from this thread: https://forums.macrumors.com/threads/itunes-12-6-5-3-on-apple-silicon.2354390/ ...works without disabling SIP

Didn't work for my use though as my ITL is 12.9.5 (from Mojave)...really wanted all the data preserved.

so I got it working, what you need to do is forget Retroactive, get a copy of iTunes 12.9.5.5 from Mojave, zip it, move it over to new Mac, and unzip/put it in ~/tmp ( ~/tmp/iTunes.app) and then run these commands:

xcode-select --install

plutil -replace CFBundleGetInfoString -string 'iTunes 13.9.5.5' ~/tmp/iTunes.app/Contents/Info.plist
plutil -replace CFBundleShortVersionString -string 13.9.5 ~/tmp/iTunes.app/Contents/Info.plist
plutil -replace CFBundleVersion -string 13.9.5 ~/tmp/iTunes.app/Contents/Info.plist
ditto -c -k --sequesterRsrc --keepParent ~/tmp/iTunes.app ~/Desktop/iTunes12.9.5.5_Patched.zip
ditto ~/tmp/iTunes.app /Applications/iTunes.app

paste them in as 4 chunks above...no need to do each individually.
