You cannot install ANY version of operating system past today’s date OFFLINE unless…. I just spent an entire day going through every possible trouble shooting procedure available to discover why my installers all report as “damaged”. In fact a quick search today will show people asking why their external installers will not show up on Option boot operations or boot or install.

Mark my words, this latest time bomb will also be recorded by the technical community just like the other one.

Now I tried those “damaged” installers once again and like magic, now they all work just like before. I booted the Mac on a completely different system and changed its date back one year. My notes said that Apple once made a software time bomb that screwed up everybody.

how?….Magic?)Įrror Message said that the installers were all “damaged” and could not be used.įurther tests revealed that none of my High Sierra installers would work either. That seems darn suspicious huh? (the DVD altered its content?,…. NONE of my Mojave installers would function. No, I am not joking, that is historical fact all non geek Mac users know. That’s right, they all stopped on Valentine’s Day. On Februall the updaters and installers that all these competent people created and kept stored stopped working. NONE of my installers would install, neither the DVD or thumb drive versions. So I began today (Thursday Nov 7 2019) to install Mojave 10.14.3 as a random choice to test the AIFF file issue. I have made such an installer for all versions of Apple OS for more than a decade. The customer must learn from others, how to create an installer since Apple has not made an installer the customer can purchase for more than a decade. My first step in troubleshooting was to go backwards. No competent person would say anything that accuses the computer or its components as the cause. (in fact overt lies and personal attacks) No help is given and the only response appears to be at least inaccurate in its report. This thread begins with Mojave 10.14.6 will not play a CD or any other AIFF file “properly” on a Nehalem Mac Pro using Line Out. Apple deleted this thread from Apple Discussions.
