For the past month or so, Mac portable Prezis seem to be in a new format named “prezi.portable-v234”. The files don’t look like typical Mac executable program files, but the presentations seem to run perfectly on 2 of my computers when double-clicked. I’m using an iMac 27 with Sierra and a MacBook Pro with OS X Sierra 10.12.3.
When the same files are transferred to other Macs, some with Sierra and some with earlier systems, the files don’t run at all. They appear as folders containing 2 primary files, “prezi.json” and prezi.xml", a number of subfolders named for various support file types – fonts, images, etc.
It doesn’t matter how the portable Mac press are transferred, whether by USB stick, portable Mac formatted hard drive, email, Drop Box or whatever, we can’t defeat the files showing up as folders and therefore not running as portable prezis.
There are no such issues with Windows .exe files.
Our files are intended for use by Medical Education instructors across Canada, and this has become a serious logjam in distributing course material. We really need to solve this quickly!
I posted this problem earlier, but it didn’t seem to appear in the forums. Please forgive if this comes up as a duplicate.
