After update to High Sierra, Pages/Keynote/Numbers wont open
Hi,
I updated my mid2011 iMac from ElCapitan to High Sierra. After this, I could not open Pages/Keynote/Numbers any more. I tried to update at the appstore purchased tab. This prompted to download the last compatible versions, which I did.
After installation I still just get "Numbers quit unexpectedly." when I try to open the apps. I read in the crash report:
Exception Type: EXC_CRASH (Code Signature Invalid)
Exception Codes: 0x0000000000000000, 0x0000000000000000
Exception Note: EXC_CORPSE_NOTIFY
Termination Reason: Namespace CODESIGNING, Code 0x1
I do not know how to solve this issue and any hint is highly appreciated. Thanks!
iMac 27″, macOS 10.13
