Etrecheck – System Information

Quite a few people have had the same issues with 10.10 after the iTunes update the other day. If you have time machine its a real easy fix. Another person on this forum figured it out and it worked for everyone that has done it so far...

Set this window on your screen before going into Time Machine.....

System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice

Then in Time Machine click on the same folder on a date before the update and restore.

This should do it!

Just as a note, I also had an issue backing up my phone in iTunes as well as not being able to open safari. This fix, fixed both issues.

See this discussion, There is a download of the old file.

i have fixed this issue，copy the System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice from your backup or other mac without update，restart the safari ...... done ！

Do you have a backup you can restore from? If so, go into the backup to a time when Safari worked. Select your hard drive, then the System folder. Select Library, then PrivateFrameworks. Then MobileDevice.framework/Versions/A/MobileDevice. Restore that file. Quit/reopen Safari and test.

Worked perfectly, the window that you choose will stay at the front in Time Machine and you just click restore on the 'MobileDevice' icon. I replaced it with one from 6 months ago.

All working now. Thanks !!!

Thanks! Restoring the file from

my TimeMachine Backup solves the problem for me

Also the Safari error window will keep popping up so I have to keep it on the lower corner of my screen or it literally keeps popping up during the whole time my computer is opened. And if I open iTunes then the MobileDevice error window does the exact same thing.........

Frustrated

THANK YOU!!!!! Safari works and will be testing if iTunes see's my iPhone to sync and backup next! Wish I knew in detail software, coding and computers. I know a little but not as much as I wish. I can't understand what happened with the "MobileFramework" the moment iTunes automatically updated to 12.8.1. Seems like an software issue. Wonder if its an issue with the iTunes update directly or because I am using a Macbook Pro 2011 running Yosemite 10.10.5...

Thanks again! I spent 3 hours last night reading and trying to figure out what was the issue...

Dont know if this would help but i noticed at least in Time Machine it gives a lot of dates but not all date have actually backups. Just confirm that the day you picked has an actual backup. In Time Machine if I remember correctly it will be highlighted in red when your mouse goes over it.

I have the exact same problem. I'm on 10.10.5 and updated itunes last night to 12.8.1 and it killed my Safari as well. Everything else seems to work okay though. Apple please fix.
