Not functioning on High Sierra (10.13.1)

[dmlemos]

Recently upgraded to 10.13.1, and after disabling SIP and patched iTunes is still opening. It was working before with Sierra up until now.

Attached is the log com.thebitguru.Play-Button-iTunes-Patch 2017-12-02 17-32.log

Hi, @dmlemos,

Thanks for reporting this and sharing the log file. Based on the log, the file should already be patched. Can you confirm that you restarted your Mac after patching? Also, by any chance, are you trying the play/pause button on a Bluetooth headset?

[dmlemos]

I tried to patch it twice. And yes I restarted the mac. Just using the internal keyboard nothing more.

[thebitguru]

That's really weird. The log says that the file is patched. Can you attach the output of the following command?

strings /System/Library/CoreServices/rcd.app/Contents/MacOS/rcd

Doesn't work for me on High Sierra as well. The patch GUI said that the rdc status was "Patched." when I first ran it, even though I had not run it before. I ran the patching anyway, it prompted for my password several times, and proclaimed that it was patched and now there was a backup.

Here are some comparisons of the patched file and the backup:

Johnny-Five:~ peter$ ls -l /System/Library/CoreServices/rcd.app/Contents/MacOS/rcd*
-rwxr-xr-x  1 root  wheel  40656 Dec  5 18:20 /System/Library/CoreServices/rcd.app/Contents/MacOS/rcd
-rwxr-xr-x  1 root  wheel  41296 Dec  5 18:20 /System/Library/CoreServices/rcd.app/Contents/MacOS/rcd_backup_1.1_20171205_18_20.22

Johnny-Five:~ peter$ cksum /System/Library/CoreServices/rcd.app/Contents/MacOS/rcd*
794668000 40656 /System/Library/CoreServices/rcd.app/Contents/MacOS/rcd
2939926531 41296 /System/Library/CoreServices/rcd.app/Contents/MacOS/rcd_backup_1.1_20171205_18_20.22

Johnny-Five:~ peter$ strings /System/Library/CoreServices/rcd.app/Contents/MacOS/rcd > rdc.strings
Johnny-Five:~ peter$ strings /System/Library/CoreServices/rcd.app/Contents/MacOS/rcd_backup_1.1_20171205_18_20.22 > rcdbak.strings
Johnny-Five:~ peter$ diff rdc.strings rcdbak.strings 
Johnny-Five:~ peter$ 

No difference in the strings output between the patched one and the backup.

I've attached the strings output from the patched one, since there was no difference, the log file, and a screenshot of the GUI after patching.

Looks like _FIND_COMMAND_DATA is no longer in the executable. Wonder if that has been moved off somewhere else.

[thebitguru]

Sorry, I have been quite consumed by my primary job. I will look into this as soon as I can.

[peterguy]

No apology needed - be glad you have a primary job! :-)

I saw your clever hack in Patcher.m, and I did some digging through the strings of various other executables involved in the launching of iTunes, like mediaremoted, but I did not find any obvious candidate for the same kind of command substitution.

macOS Sierra really messed up the RCD hacking crowd - there is a liberal sprinkling of "doesn't work in macOS Sierra!" issues, like this one, so you are not alone. I have a feeling a completely different approach will be needed.

[pickanothername]

+1 for this. Had the same exact experience, and I'm at my wit's end.

[thebitguru]

@peterguy :) Thanks for sharing the details! I finally got a chance to start looking more into this. I agree with your assessment that Apple has changed how they are launching iTunes in 10.13, I didn't find any references to the string that the patch was replacing before.

Sounds like this will require some serious detective work again.

I have noticed that in High Sierra I haven't needed this. I did switch to a different media player (Swinsian) which could be the reason. Can one of you please let me know the name of the media player that you are using where this is an issue?

[peterguy]

No alternate media player here: I was actually hoping to use your patch to stop iTunes from launching every time I connected to a bluetooth speaker.

I use cmus and sometimes spotify.

Hi guys, to bad this is not working anymore :-( I don't know if that could help you but this project does some jam with the media keys, maybe it's approach could be reusable https://github.com/milgra/highsierramediakeyenabler
