Old MBP worked fine until latest update - MP4s broken

[donovanw3037157]

I know I am using an old MBP, but I have used Premiere on it for over a year with no problems. I updated to the lastest software and all things went to hell. Can't get any mp4s to work at all. It loads just audio and gives me the "low level exception" error. I followed everything I could online, clearing/cleaning/deleting/reloading software etc. Nothing worked.

I then tried to go back to an older version software.  I thought I remembered being able to go through all versions... but now it only gives you specific versions you can go to. I don't remember what my last working version was, but I tried all the versions that you had available to me thru CC and the same error with mp4 (in H 264) came up. 

So I transcoded a folder full of my mp4s to Apple Prorez...and that at least imported to my timeline properly, but when I tried to render the timeline I got another low level error message.

So what gives???  I don't mind running an earlier version if you tell me my Mac is the problem...but I can't get back to making an earlier version work.  As it stands now your software is broken and unusable to me.

Thanks,

According to the Minimum Requirements for Mac found here:

Adobe Premiere Pro CC System Requirements

For the October 2018 release (13.0) you need OS 10.12 or greater and 16 GB minimum RAM.

Did you make a backup of your computer prior to attempting the upgrade? If so you could restore back to that.

No. No backup. Tried returning to the last two prior versions and mp4s still don't work.  I tried uninstalling versions and then reloading from scratch...but something from the new update is still buried somewhere deep in my system because mp4s do not work.

Funny you would think that Adobe would have built into their software a check to make sure you are running the correct OSX software before letting you update. Other apps do??

So easy with CC saying "there is an update" to coax you into updating into a mess.
