Two things. One is off topic. The time in the upper right hand corner is ofd by 7 -8 minutes every week. When I open it corrects itself.
Issues with DPP. My 24-70II for DLO would not not update. It was like this for a while and I just thought Canon had not released it yet. I decided to reinstall DPP.
Did a full uninstall and used the disk that came with my 5D3. Install was great but every time I tried to update to 3.13.51 DPP crashed when I tried to open an image. Canon USA detects your OSX and auto selected Mavericks.
I tried several more times with no success. I then tried the Canon Canada website and it does not detect your OXS version, it just has a drop down box and you have to select it. It offered 10.9 (and lower) which is Mavericks, they just don't include the name. I tried that about 3 times and it failed as well. I went back to the Canon USA site and again it detected Mavericks however since that just continued to fail I clicked on the drop down box and on a whim tried 10.8 and I was able to update to 3.13.51 without crashing. Not sure why that worked, but it did, so I don't really care.
I was also to successfully update all my lenses as well. What a nightmare. I would be have been easier if I didn't have to restart the commuter each time. What an archaic system. Probably programmed by the dinosaurs
