Download Issue

I found 2 issue as i download league of legends again, on mac

In 1/2 or 33 percent of the download, it went pretty fast. Scaling from 500-1300 Kbps

But in 2/2 or 33-100 percent of the download, it was so slow! Scaling from 0-500 Kbps

The another issue that is the most annoying is

It crash! So let say, i got to 36 percent and it crashed. When i reopen it, it start over from 33 percent. I do it again, get to 35 percent, CRASHED. Reopen it, it start over from 33 percent.

Question is, Why is it slow for 2/2?

Why is it starting from 33% when you already download the extra percentage of the software. Does it download over on top?

Im still stuck with the download because of this issue.

FYI, this never happen before, when i started this game in 2012

Please response to this post. I can't play it after clean everything on my mac.

Is anyone facing the same issue?

Not sure if i will ever get to play it. A good update would need to be on this... THX
