Thank you much for your answer. I tried to updated but I get this error. Checking "(null)"
At what point does that error appear?
Were you able to download the upgrade application?
As soon as I click Agree.
Thank you
No I didn’t. I got the error as soon as I click agree.
Thank you again
As soon as I click Agree. Never start the download.
The download usually works well with the Safari browser.
If Safari isn't working properly, I suggest you try downloading with the Firefox browser, or maybe Brave browser.
