do I have to remove High Sierra to install Mojave?
Mac Pro
Thanks, Neil. I have been trying unsuccessfully for five hours to install Mojave on my Mac Pro (late 2013). Each time I get this message:
This copy of the Install macOS Mojave.app application is damaged, and can’t be used to install macOS.
If you get a corrupted message...
Naw, not damaged, it's just that you have an old copy already in Applications, there are 2 cures...
Disconnect from the Internet & set the Date back to 2014, then you can run the Install MacsOS Mohave App in Applications, so expired Certificates are not expired.
Or... trash the Install MacsOS Mojave.app in Applications, empty trash & restart, then a new copy of a more recent version can be downloaded..
Sweet, if you have great internet & no data limits the second option is best my friend! :)
No.
