Well, I'm 1 for 2 on this one; the Extension Manager 6.0.8 Update installed fine, however, the Adobe Bridge CS6 5.0.2 Update seems to be either broken or needs some additional installation software ... I get the error message. "Updatges could not be applied ... Adobe Application Manager maybe be damaged. Download and install a new copy of Adobe Application Manager".
This has me stumped as the CS6 Adobe Application Manager is not missing and doesn't appear to be damaged, but I suspect it may be out-of-date and creating a conflict and giving a misleading erro message. Some other posts suggests to remove it completely, others say to remove and re-install. I can't find anywhere to download load a stand-alone version to re-install as the pop-up error message would seem to imply. Is there a download for the Adobe Application Manager?
Is there such a thing as a stand-alone version of the Adobe Bridge CS6 5.0.2 Update that does not require the Adobe Application Manager?
I've found a work-around to allow the Adobe Bridge CS6 5.0.2 Update to proceed;
It seems that all of the other stand-alone CS6 updates will run directly from the mounted *.dmg disk image file and install the update directly, however, the Bridge update was not following that same scenario.
Not being sure whether the AdobePatchInstaller that came with the Bridge 5.0.2 update was corrupted or limited in some way, I copied the AdobePatchInstaller from another CS6 update along with the original "payloads" folder from the Bridge update and placed them in a new folder on my desktop. From there, double-clicking on that alternate AdobePatchInstaller worked without error, correctly installing the Bridge 5.0.2 update.
In hindsight, I doubt there was a corruption in the AdobePatchInstaller that came with the Bridge 5.0.2 update disk image, rather it was probably a Mojave OS quirk that forced this work-around.
